Description

Technical Field

[0001] This application relates to the field of chassis technology, and in particular to a chassis, energy storage system and data system. Background Technology

[0002] Air conditioning is widely used in residential and industrial settings for indoor heat exchange. In industrial applications, it is used in energy storage containers, which are crucial components of photovoltaic energy storage systems. These containers contain numerous batteries, and as battery stacking capacity and rate capabilities increase, efficient control of battery temperature rise is key to the temperature control of the enclosure system. Low cost for the entire temperature control system is also a core competitive advantage. Currently, integrated air conditioners are typically installed on both sides of the enclosure, using the air conditioner to deliver cool air to cool the batteries. However, this temperature control architecture suffers from drawbacks. Electrical devices farther from the air conditioner experience poor heat dissipation due to insufficient airflow, leading to higher cell temperatures and shorter battery life. Furthermore, the long internal airflow path of the air conditioner results in greater air resistance and lower overall temperature control efficiency. Summary of the Invention

[0003] This application provides a chassis with better heat dissipation.

[0004] In a first aspect, this application provides a chassis, the chassis including a shell, an electrical device, and a thermal control device. The electrical device is located in a receiving cavity within the shell, and includes a fan, a first air vent, and a second air vent. The fan is used to accelerate the airflow speed between the first air vent and the second air vent. The thermal control device includes a first heat exchanger, a second heat exchanger, and a heat exchange medium. The first heat exchanger and the second heat exchanger are connected by a pipe. The heat exchange medium is located in the first heat exchanger and the second heat exchanger and can flow between the first heat exchange tube and the second heat exchange tube. The first heat exchanger and the second heat exchanger achieve heat exchange between the inside and outside of the shell through the thermal circulation of the heat exchange medium. The first heat exchanger is located in the receiving cavity and adjacent to the first air vent.

[0005] Fans are structural components of electrical devices, used to dissipate heat from components within the internal space of the electrical device.

[0006] The electrical device includes electrical components. When the electrical device is working, the electrical components are the main heat source for the electrical device to generate heat. The fan in the electrical device is used to dissipate heat from the electrical components. The fan can blow air to flow on the surface of the electrical components to dissipate heat from the battery cells.

[0007] In this application, the air circulation between the internal space of the electrical device and the receiving cavity is achieved by using the fan of the electrical device itself, eliminating the need for an additional fan, saving costs and receiving cavity space. Furthermore, the first heat exchanger is located near the first air outlet of the electrical device, enabling the first heat exchanger to exchange heat with the electrical device in a timely manner, thereby improving the heat exchange effect on the electrical device and enhancing the heat exchange efficiency of the heat control device on the electrical device.

[0008] In one embodiment, the chassis is an energy storage container, the electrical device is a battery module, and the electrical components are battery cells. The battery module generates a large amount of heat during operation, and a fan is used to dissipate heat from the battery cells. In some embodiments, the chassis can be a data center, which can be a small data center, such as a server rack, or a large data center, such as a data center room. In some embodiments, when the chassis is a server rack, the electrical device is a server, and the electrical components are electronic components within the server. The server generates a large amount of heat during operation, and a fan is used to dissipate heat from the electronic components within the server. In other embodiments, the chassis can also be other equipment requiring heat exchange.

[0009] The airflow velocity between the first air outlet and the second air outlet includes the flow velocity from the first air outlet, through the internal space of the electrical device, to the second air outlet, or the flow velocity from the first air outlet, through the receiving cavity, to the second air outlet. The increased airflow velocity inside the electrical device will also increase the airflow velocity in the receiving cavity outside the electrical device.

[0010] When the fan operates, it drives air to circulate between the first air vent, the internal space of the electrical device, the second air vent, and the receiving cavity. These three components form an airflow circulation channel, within which the fan is located. In one embodiment, the fan drives air from the first air vent into the internal space of the electrical device, then from the second air vent into the receiving cavity. The fan then draws air from the receiving cavity and delivers it back to the first air vent, thus forming the airflow circulation channel. In another embodiment, the first air vent is the air inlet of the electrical device, and the second air vent is the air outlet of the electrical device.

[0011] In one embodiment, the first air outlet is the air outlet of the electrical device, and the second air outlet is the air inlet of the electrical device. A fan drives air to flow from the second air outlet into the internal space of the electrical device, then from the internal space back to the first air outlet and out of the first air outlet into the receiving cavity. The fan then draws in air from the receiving cavity, causing air to enter the internal space of the electrical device from the second air outlet, thus forming an airflow circulation channel. In this application, the airflow circulation channel is formed by the electrical device's own fan, eliminating the need for an additional fan, saving costs, and conserving internal space within the receiving cavity without occupying other space.

[0012] The first and second heat exchangers are components capable of conducting heat and can be air-liquid heat exchangers. The heat exchange medium changes from a first state to a second state when it absorbs sufficient heat, and from a second state to a first state when it releases heat, thus achieving a heat cycle. For example, the heat exchange medium changes from liquid to gas when it absorbs sufficient heat, and from gas to liquid when it releases sufficient heat. The heat exchange medium is a refrigerant, such as water, ethylene glycol, acetone, or methanol.

[0013] In one embodiment, when the electrical device needs to be cooled, the heat generated by the operation of the electrical device causes the air in the containment cavity to heat up through the airflow circulation channel. The first heat exchanger located in the containment cavity absorbs the heat of the air in the containment cavity and transfers the heat to the heat exchange medium in the first heat exchanger. After absorbing the heat, the heat exchange medium heats up and vaporizes into a gas. The gaseous heat exchange medium flows to the second heat exchanger, which is used to transfer the heat of the gaseous heat exchange medium to the outside of the housing, thereby realizing the inside-outside heat exchange process of transferring the heat inside the housing to the outside of the housing.

[0014] In one embodiment, when the internal temperature of the electrical device needs to be increased, for example, when the chassis is located in an extremely cold region and the internal temperature of the electrical device is too low to reach the normal operating temperature, the electrical device needs to be heated to ensure normal operation. A second heat exchanger heats the heat exchange medium within it. The heated medium then flows to a first heat exchanger, where it transfers heat to the air in the containment cavity. The heated air in the containment cavity heats the electrical device through an airflow circulation channel, thereby achieving an outside-to-inside heat exchange process that transfers heat from the outside of the casing to the inside.

[0015] The internal-to-external and external-to-internal heat exchange processes are achieved by the thermal circulation of the heat exchange medium between the first and second heat exchangers. The first heat exchanger is located within the containment cavity and facilitates heat exchange between the air within the cavity and the heat exchange medium within it. The heat exchange medium can flow from the first heat exchanger to the second heat exchanger. The installation position of the second heat exchanger can be arbitrarily set, as long as heat exchange between the heat exchange medium in the second heat exchanger and the outside of the casing is achieved. The casing includes a top cover and a bottom plate arranged opposite each other along a first direction. The second heat exchanger is located in the top cover of the casing, where the first direction is the height direction of the casing. In some embodiments, the second heat exchanger is located on the side of the casing.

[0016] In this application, the first heat exchanger is positioned adjacent to the first air inlet, so that the airflow entering the internal space of the electrical device from the first air inlet passes through the first heat exchanger, or the airflow exiting the internal space of the electrical device from the first air inlet passes through the first heat exchanger. This allows the air inside the electrical device to exchange heat with the first heat exchanger in a timely manner, improving the heat exchange efficiency of the electrical device. For example, when the electrical device needs to be cooled, assuming the first air inlet is an air inlet, the electrical device generates heat during operation, and the fan operates, driving the cold air cooled by the first heat exchanger to quickly enter the internal space of the electrical device from the first air inlet, thus cooling the electrical device in a timely manner. This reduces the distance the cold air needs to travel from the first heat exchanger to the internal space of the electrical device, reducing heat loss and improving the cooling effect of the electrical device. Here, the electrical device is the heat source that generates heat, and the first heat exchanger is the cold source that cools the electrical device. Positioning the heat source (electrical device) and the cold source (first heat exchanger) adjacent to each other provides a better heat exchange effect, thereby improving the heat dissipation efficiency of the electrical device.

[0017] The fan is the electrical device's own fan, typically located inside the device or in its first and second air vents. This means the fan is closer to the first vent, resulting in the highest airflow and velocity. When this high-flow-rate air passes through the first heat exchanger, a larger volume of air exchanges heat with it per unit time, improving heat exchange efficiency. If the fan is placed further away from the electrical device, the airflow driven by the fan is dispersed within the enclosure, reducing the airflow and velocity reaching the first heat exchanger, thus decreasing its heat exchange efficiency.

[0018] In one embodiment, the first heat exchanger may include a first heat exchange tube. In another embodiment, the first heat exchanger may include a first heat exchange tube and heat-conducting fins, with the first heat exchange tube passing through the heat-conducting fins, which increase the contact area for heat exchange with the air. The first heat exchanger may also be other structural components; for example, when the first heat exchanger is used to cool air, it may be an evaporator.

[0019] In one possible implementation, the electrical device includes a housing and electrical components located within the housing, the housing including the first air vent and the second air vent, and the fan located at at least one of the following locations: the first air vent, the second air vent, and the interior space of the housing.

[0020] The housing refers to a casing for housing electrical components, which are the electrical components of the electrical device. The housing and the electrical components located within it constitute an electrical compartment. In one embodiment, the electrical device is a battery module, and the housing is a casing for housing battery cells. In one embodiment, the electrical device is a server, and the housing is a casing for housing electronic components. In one embodiment, the electrical device is a battery module, and the housing and the battery cells located therein constitute a battery compartment.

[0021] In one embodiment, the first air vent and the second air vent are arranged opposite each other along a second direction, which intersects with the first direction. The first air vent is an air inlet, and the second air vent is an air outlet. The fan is located at the first air vent, so that air that has undergone heat exchange with the first heat exchanger is directly blown into the internal space of the chamber shell from the first air vent, where it undergoes heat exchange with the electrical components, thereby improving heat exchange efficiency. In some embodiments, the first air vent is an air outlet, and the second air vent is an air inlet. Air exiting the internal space of the chamber shell directly exchanges heat with the first heat exchanger after exiting from the first air vent.

[0022] In one embodiment, the fan can also be located inside the casing, which is also the internal space of the electrical equipment. The fan can be located anywhere within the casing, specifically according to the arrangement of the electrical components, to ensure a reasonable layout of the fan and electrical components, guaranteeing sufficient ventilation and the number of electrical components. In one embodiment, the fan can be located at the second air vent. In another embodiment, there are two fans, located in the first and second air vents respectively.

[0023] The fan located at the first air vent includes the fan being fixed to the side of the first air vent facing the interior space of the silo shell, or the fan being fixed to the side of the first air vent away from the interior space of the silo shell, or the fan being fixed to the silo shell surrounding the first air vent. The fan located at the second air vent includes the fan being fixed to the side of the second air vent facing the interior space of the silo shell, or the fan being fixed to the side of the second air vent away from the interior space of the silo shell, or the fan being fixed to the silo shell surrounding the second air vent.

[0024] In one embodiment, the electrical device includes a plurality of fans, which are respectively located at the first air vent and the second air vent. In one embodiment, the plurality of fans are respectively located at the first air vent and within the internal space of the housing. In another embodiment, the plurality of fans are respectively located at the second air vent and within the internal space of the housing. In yet another embodiment, the plurality of fans are respectively located at the first air vent, the second air vent, and within the internal space of the housing. This arrangement of multiple fans can increase airflow speed.

[0025] In one embodiment, when the heat control device is used to cool the electrical compartment, a fan drives the air cooled by the first heat exchanger to flow from the first air outlet into the internal space of the compartment shell to cool the electrical components. The air then heats up and flows from the second air outlet into the receiving cavity. Through the airflow circulation channel, the air returns to the first air outlet and is cooled by the first heat exchanger. The cooled air then re-enters the internal space of the compartment shell, which can effectively improve the cooling efficiency of the electrical components inside the compartment shell.

[0026] In some implementations, the heat control device can be used to heat the electrical compartment. The specific heating process is similar to the heating process described above and will not be repeated here.

[0027] In one embodiment, the housing includes a first side door, a first air vent facing the first side door, and a first heat exchanger located between the first side door and the first air vent, and fixed to the inner surface of the first side door facing the electrical device. Mounting the first heat exchanger on the first side door facilitates maintenance of both the first heat exchanger and the electrical device; maintenance of the first heat exchanger can be performed simply by opening the first side door.

[0028] In one embodiment, the first heat exchanger may also be fixed to the outside of the electrical device. The housing includes a first side door located on one side of the electrical device along the second direction. A first air vent and a second air vent are disposed opposite each other along the second direction. The first side door is positioned closer to the second air vent than the first air vent. The first heat exchanger is fixed to the outside of the electrical device.

[0029] In some embodiments, multiple first heat exchangers are also provided on other sides of the electrical device to improve the heat exchange effect on the electrical device.

[0030] In one possible implementation, the electrical device includes a plurality of stacked housings. In each housing, the first heat exchanger is located outside the first air vent, and at least a portion of the first heat exchanger is opposite to the first air vent. In one embodiment, the housing also includes a top cover and a bottom plate disposed opposite each other along a first direction, with the electrical device located in the area between the top cover and the bottom plate. The stacking direction of the plurality of housings is the first direction. The first heat exchanger extends along the first direction, such that each housing has a portion of the first heat exchanger at its first air vent, allowing for more uniform heat dissipation for each electrical compartment. In one embodiment, the first direction is the height direction of the housing, and the second direction is the width direction of the housing.

[0031] In one embodiment, a portion of a first heat exchanger is provided at the first air vent of each compartment shell. When cooling the electrical equipment, the heat exchange medium in the first heat exchanger is liquid. The liquid absorbs heat and turns into gas. The difference in the amount of heat absorbed by the liquid heat exchange medium at any location in the first heat exchanger as it turns from liquid to gas is relatively small. In one embodiment, a larger amount of liquid heat exchange medium can be provided in the first heat exchanger so that the liquid heat exchange medium can flow to any part of the first heat exchanger, or at least to the portion of the first heat exchanger near the first air vent of each compartment shell. This makes the heat absorption effect of the portion of the first heat exchanger near the first air vent of each compartment shell comparable, thereby improving the uniformity of heat dissipation to each electrical compartment in the electrical equipment.

[0032] In one embodiment, the electrical device includes an electrical support, on which a plurality of electrical compartments are disposed. In some embodiments, the plurality of electrical compartments may be directly stacked along a first direction.

[0033] In some embodiments, the electrical device includes a device housing and electrical components located within the device housing. The device housing includes a first air vent and a second air vent, and the fan is located at at least one of the following locations: the first air vent, the internal space of the device housing, or the second air vent. In one embodiment, the electrical device is a battery module, the battery module including a module housing and battery cells located within the module housing, the battery cells being directly disposed within the module housing. The module housing includes a first air vent and a second air vent, and the fan is located at at least one of the following locations: the first air vent, the internal space of the device housing, or the second air vent.

[0034] The first air vent and the second air vent are respectively disposed on the housing of the device housing, which is disposed opposite to each other along the second direction. The fan is fixed to the device housing by means of clips, screws, etc., and the specific method is not limited. In one embodiment, when the electrical device includes multiple electrical components arranged along the first direction, the multiple electrical components can be arranged along the first direction by means of a bracket or stacking, and multiple first air vents, multiple second air vents, and multiple fans are disposed on the housing of the device housing on both sides along the second direction, so that each electrical component has a first air vent and a second air vent on both sides along the second direction, and a fan that can blow air directly onto the electrical component.

[0035] In one possible implementation, the chassis includes a plurality of electrical devices arranged in an array, and the heat control device includes a plurality of first heat exchangers, with each of the plurality of electrical devices having a first heat exchanger at the location of a first air vent. The plurality of electrical devices are arranged in a third direction, which intersects with both a second direction and a first direction. In one embodiment, the first direction is the height direction of the chassis, the second direction is the width direction of the chassis, and the third direction is the length direction of the chassis.

[0036] In one embodiment, the electrical device comprises multiple electrical compartments. When a first heat exchanger is used to cool the multiple electrical devices, a portion of the first heat exchanger is installed at the first air vent of each electrical compartment within each electrical device. This improves the heat dissipation effect on each electrical compartment and enhances the uniformity of heat dissipation across all electrical devices. In another embodiment, the number of electrical devices arranged in a third direction is unlimited; even with a large number of electrical devices, good heat dissipation uniformity is still achieved. When the first heat exchanger is used to heat the multiple electrical devices, good heating uniformity is achieved.

[0037] In one embodiment, when there are multiple first heat exchangers, the heat control device may include one or more second heat exchangers. When there is only one second heat exchanger, it is connected to multiple first heat exchangers for heat exchange of the working fluid in the multiple first heat exchangers. When there are multiple second heat exchangers, each second heat exchanger may be connected to multiple first heat exchangers respectively for heat exchange of the working fluid in the multiple first heat exchangers, and the specific configuration can be determined according to actual needs.

[0038] In some embodiments, the chassis includes a plurality of electrical devices arranged along the second direction, with a first heat exchanger disposed on the outside of each electrical device. The number of first heat exchangers can be increased to accommodate the number or distribution of the electrical devices, and the distributed layout of multiple first heat exchangers can dissipate heat from each electrical device, improving the heat dissipation effect.

[0039] In one embodiment, two electrical devices are arranged along the second direction, and the first air vents of the two electrical devices arranged along the second direction are respectively adjacent to the first side door and the second side door on both sides.

[0040] In one embodiment, two electrical devices are arranged along the second direction, and the first air vents of the two electrical devices arranged along the second direction are respectively far away from the first side door and the second side door on both sides.

[0041] In some embodiments, two or more electrical devices are arranged along the second direction, in which case the first heat exchanger of the electrical device located between the electrical devices can be fixed to the electrical device.

[0042] In one possible implementation, the heat control device further includes a flow guide housing, the flow guide housing and the first heat exchanger being located on the same side of the electrical device along the second direction, the flow guide housing and the first heat exchanger extending along a first direction, the second direction intersecting the first direction, the first heat exchanger being located inside the flow guide housing, the flow guide housing being provided with a third air vent and a fourth air vent, the third air vent being disposed closer to the first air vent than the fourth air vent, the third air vent and the first air vent being used to connect the internal space of the flow guide housing and the internal space of the electrical device, and the fourth air vent being used to connect the internal space of the flow guide housing and the receiving cavity.

[0043] The third and fourth air vents are located within the airflow circulation channel. When the first air vent is the outlet of the electrical device and the second air vent is the inlet of the electrical device, the third air vent is the inlet of the guide shell and the fourth air vent is the outlet of the guide shell. The air coming out of the first air vent passes through the third air vent and enters the internal space of the guide shell, where it is cooled by the first heat exchanger. The guide shell allows the air to stay briefly in its receiving hole, thus increasing the contact time between the air and the first heat exchanger and enabling sufficient heat exchange.

[0044] In one embodiment, the third air vent overlaps with the central axis of the first air vent, making the airflow between the first air vent and the third air vent smoother.

[0045] In one embodiment, the airflow guide shell includes a first side plate, a second side plate, a third side plate, and a fourth side plate. The first and second side plates are arranged opposite each other along a second direction, and the third and fourth side plates are arranged opposite each other along a third direction. The first, third, second, and fourth side plates are sequentially connected to form the airflow guide shell. The first side plate is located adjacent to the first air outlet, the third air outlet is located on the first side plate, and a fourth air outlet is provided on both the third and fourth side plates. The air entering from the third air outlet can be divided into two paths and discharged from the fourth air outlets on the third and fourth side plates respectively.

[0046] In one embodiment, the housing further includes a top cover and a bottom plate disposed opposite to each other along the first direction, with the airflow guide housing located between the top cover and the bottom plate. The airflow guide housing includes a third air outlet and a fourth air outlet. The maximum vertical distance between the edge of the third air outlet and the bottom plate is greater than the minimum vertical distance between the edge of the fourth air outlet and the bottom plate, and less than or equal to the maximum vertical distance between the edge of the fourth air outlet and the bottom plate. This allows air to flow from the third air outlet to the fourth air outlet, or vice versa, increasing airflow speed while ensuring sufficient heat exchange. The first direction is perpendicular to the bottom plate.

[0047] In one embodiment, the maximum vertical distance between the edge of the fourth air vent and the base plate is greater than the minimum vertical distance between the edge of the third air vent and the base plate, and less than or equal to the maximum vertical distance between the edge of the third air vent and the base plate, wherein the first direction is perpendicular to the base plate.

[0048] In one embodiment, the vertical distances between the upper and lower edges of the third air vent and the fourth air vent and the base plate are equal. Specifically, the maximum vertical distance between the edge of the third air vent and the base plate is equal to the maximum vertical distance between the edge of the fourth air vent and the base plate, and the minimum vertical distance between the edge of the third air vent and the base plate is equal to the minimum vertical distance between the edge of the fourth air vent and the base plate.

[0049] In one embodiment, there are two fourth air vents. In another embodiment, there are three fourth air vents.

[0050] In one embodiment, the third and fourth air vents are rectangular in shape, and the length direction of the rectangle is the same as the first direction. In another embodiment, the third and fourth air vents are square in shape. In yet another embodiment, the third and fourth air vents are elliptical in shape, etc. In one embodiment, when there are two or more fourth air vents, the maximum vertical distance between the upper edge of each fourth air vent and the base plate may be the same or different, the minimum vertical distance between the lower edge of each fourth air vent and the base plate may be the same or different, and the shape of each fourth air vent may be the same or different.

[0051] In one embodiment, when the electrical device includes multiple housings, the airflow guide housing is provided with multiple third air vents, each of the third air vents being disposed opposite to a first air vent of one of the housings, and at least one of the fourth air vents satisfying the aforementioned vertical distance relationship with one of the third air vents. In one embodiment, the airflow guide housing provides one third air vent and one fourth air vent for each housing.

[0052] In one embodiment, a water receiving tray and a water pump are provided at the bottom of the flow guide housing. The water receiving tray is used to collect water droplets condensed from the first heat exchanger, and the water in the water receiving tray is discharged from the housing by the water pump.

[0053] In one possible implementation, the enclosure further includes a top cover and a bottom plate disposed opposite each other along a first direction. The electrical device is located on the bottom plate, and the top cover has a receiving space, within which the second heat exchanger is located. Placing the second heat exchanger in the top cover saves space. The bottom plate has multiple fixed supports with slide rails on them, and the electrical device is located on the slide rails. When there are multiple electrical devices, there are multiple first and second heat exchangers, with multiple second heat exchangers centrally located in the top cover to save on enclosure size. In other embodiments, the second heat exchanger may also be located in a side shell of the enclosure or on the outside of the enclosure.

[0054] In one embodiment, the inlet and outlet of the first heat exchanger are located at one end of the first heat exchanger adjacent to the top cover. The inlet and outlet of the first heat exchanger may include multiple "S" loop sections or a "U" shaped loop section.

[0055] When the inlet and outlet form a U-shaped loop, the heat exchange uniformity of the electrical equipment can be improved.

[0056] When there are multiple "S"-shaped loops between the inlet and outlet, the multiple "S"-shaped loops are equivalent to having multiple "U"-shaped loops as described above, which can also improve the heat dissipation uniformity of the first heat exchanger to the upper and lower parts of the electrical device.

[0057] In one possible implementation, the pipeline further includes a first connecting pipe and a second connecting pipe. The first connecting pipe is connected between the inlet of the first heat exchanger and the outlet of the second heat exchanger, and is in communication with both the first and second heat exchangers. The second connecting pipe is connected between the outlet of the first heat exchanger and the inlet of the second heat exchanger, and is in communication with both the first and second heat exchangers. When the first heat exchanger is mounted on a first side door, the first and second connecting pipes allow the first side door to be opened smoothly. In one embodiment, the first and second connecting pipes are connecting pipes with elastic expansion and contraction capabilities, or the first and second connecting pipes have a certain length, allowing the first side door to be opened more smoothly.

[0058] In one embodiment, the second heat exchanger includes a second heat exchange tube, a compressor, an expansion valve, a heat exchange component, and an outdoor unit fan. The compressor, heat exchange component, and expansion valve are sequentially connected between the inlet and outlet of the first heat exchanger. A portion of the second heat exchange tube is between the compressor and the heat exchange component, and a portion of the second heat exchange tube is also between the heat exchange component and the expansion valve. The compressor, heat exchange component, and expansion valve are in communication with the second heat exchange tube, and the heat exchange working fluid flows within the second heat exchange tube, compressor, expansion valve, and heat exchange component. The outdoor unit fan is used to drive the external circulation between the internal space of the top cover and the outside of the housing. The top cover includes an air inlet and an air outlet. The outdoor unit fan drives external air to enter through the air inlet, exchange heat with the heat exchange component, and then discharge it from the air outlet of the top cover, thereby achieving the external circulation between the internal space of the top cover and the outside of the housing.

[0059] When the heat exchange component is a condenser, the condenser is used to cool the heat exchange medium in the second heat exchange tube. When the heat control device cools the electrical equipment, the heat exchange medium in the first heat exchanger is a low-pressure, low-temperature liquid. Low-temperature, low-pressure liquids have a low boiling point and can absorb heat quickly. The fan in the electrical equipment drives internal hot air to flow from the first air outlet to the surface of the first heat exchanger. The low-pressure, low-temperature liquid heat exchange medium absorbs heat from the hot air and becomes a low-pressure, low-temperature gas heat exchange medium. This low-pressure, low-temperature gas heat exchange medium flows from the outlet of the first heat exchanger into the second heat exchange tube, and then into the compressor. The compressor converts the low-pressure, low-temperature gas heat exchange medium into a high-temperature, high-pressure gas heat exchange medium. The working fluid, a high-temperature and high-pressure gaseous heat exchanger, is then introduced into the heat exchange component (condenser) through a portion of the second heat exchange tubes. The high-temperature and high-pressure gaseous heat exchanger can refer to a gas with a temperature and pressure higher than that of the outside air. At this time, an outdoor fan can be used to drive the outside air to cool the high-temperature and high-pressure gaseous heat exchanger in the heat exchange component (condenser). The high-temperature and high-pressure gaseous heat exchanger is cooled by the heat exchange component (condenser) to form a medium-temperature and high-pressure liquid heat exchanger. The medium-temperature and high-pressure liquid heat exchanger then enters the expansion valve through a portion of the second heat exchange tubes, and forms a low-temperature and low-pressure liquid heat exchanger through the expansion valve. The low-temperature and low-pressure liquid heat exchanger then flows to the first heat exchanger to continue cooling the electrical equipment.

[0060] A second heat exchanger is used to exchange heat with the heat exchange medium in the first heat exchanger, creating a thermal cycle between the two heat exchangers. In one embodiment, the second heat exchanger includes a compressor and an expansion valve, allowing for a lower temperature reduction in the heat exchange medium. When the lower-temperature heat exchange medium exchanges heat with air in the airflow circulation channel through the first heat exchanger to cool the electrical device, the temperature of the electrical device can be kept below the temperature outside the casing, thus improving the cooling effect. When a thermal control device is used to heat the electrical device, the second heat exchanger in one embodiment can also ensure that the temperature of the electrical device is higher than the temperature outside the casing, thereby improving the heating effect.

[0061] In other embodiments, the second heat exchanger may also include other components, such as an air filter. The second heat exchanger may also have other structural configurations, as long as it enables heat exchange with the working fluid in the first heat exchanger.

The chassis is an energy storage container, and the power generation component is used to generate electrical energy and store the electrical energy in the chassis.

[0105] In this document, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0106] Furthermore, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.

[0107] For ease of understanding, the relevant technical terms involved in the embodiments of this application will be explained and described below.

[0108] Heat loss: Heat loss refers to the heat lost to the outside world.

[0109] Cold loss: Cold loss refers to the heat absorbed from the outside.

[0110] Thermal cycling: Thermal cycling refers to a thermodynamic process in which a system starts from an initial state, goes through a series of processes, and then returns to the initial state, that is, the final state of the system coincides with the initial state.

[0111] Air-liquid heat exchanger: a device for exchanging heat between air and a refrigerant working fluid.

[0112] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.

[0113] Expansion valve: It allows medium-temperature, high-pressure liquid refrigerant to pass through its throttling mechanism and become low-temperature, low-pressure wet vapor. The refrigerant then absorbs heat in the evaporator to achieve a cooling effect.

[0114] Please see Figure 1 One embodiment of this application provides a chassis 10, which includes a housing 100, an electrical device 200, and a thermal control device 300. The electrical device 200 is located in a receiving cavity 400 within the housing 100, and includes a fan 210, a first air vent 220, and a second air vent 230 (e.g., ...). Figure 2 As shown, fan 210 is used to accelerate the airflow speed between the first air vent 220 and the second air vent 230. Fan 210 is a structural component of electrical device 200, used to dissipate heat from components within the internal space 201 of electrical device 200. In this application, electrical device 200 includes electrical component 202. In the chassis 10, when electrical device 200 is operating, electrical component 202 is the main heat source for heat generation in electrical device 200. Fan 210 in electrical device 200 is used to dissipate heat from electrical component 202. Fan 210 can blow air to flow across the surface of electrical component 202 to dissipate heat from the battery cell 202.

[0115] In this embodiment, the chassis 10 is an energy storage container 10, the electrical device 200 is a battery module 200, and the electrical component 202 is a battery cell 202. The battery module 200 generates a large amount of heat during operation, and the fan 210 is used to dissipate heat from the battery cell 202. In some embodiments, the chassis 10 can be a data center, which can be a small data center, such as a server rack, or a large data center, such as a data center room. In some embodiments, when the chassis 10 is a server rack, the electrical device 200 is a server, and the electrical component 202 is the electronic component within the server. The server generates a large amount of heat during operation, and the fan 210 is used to dissipate heat from the electronic component within the server. In other embodiments, the chassis 10 can also be other equipment requiring heat exchange.

[0116] The airflow velocity between the first air vent 220 and the second air vent 230 includes the flow velocity from the first air vent 220, through the internal space 201 of the electrical device 200 to the second air vent 230, or the flow velocity from the first air vent 220, through the receiving cavity 400 to the second air vent 230. The increased airflow velocity in the internal space 201 of the electrical device 200 will also increase the airflow velocity in the receiving cavity 400 outside the electrical device 200.

[0117] like Figure 2 As shown, when the fan 210 operates, it drives air Q to circulate between the first air vent 220, the internal space 201 of the electrical device 200, the second air vent 230, and the receiving cavity 400. The first air vent 220, the internal space 201 of the electrical device 200, the second air vent 230, and the receiving cavity 400 constitute an airflow circulation channel 20, within which the fan 210 is located. Specifically, in one embodiment, the fan 210 drives air Q from the first air vent 220 to the internal space 201 of the electrical device 200, and then from the second air vent 230 to the receiving cavity 400. The fan 210 then draws in air Q from the receiving cavity 400 and delivers it to the first air vent 220, thus forming the airflow circulation channel 20. In this embodiment, the first air vent 220 is the air inlet of the electrical device 200, and the second air vent 230 is the air outlet of the electrical device 200. Figure 2 The diagram showing the flow of air Q on one side of electrical device 200 is only shown within the containment cavity 400. In a real scenario, air Q can flow within the containment cavity 400 surrounding electrical device 200.

[0118] In other embodiments, the first air vent 220 is the air outlet of the electrical device 200, and the second air vent 230 is the air inlet of the electrical device 200, such as... Figure 3As shown, fan 210 drives air Q to flow from second air outlet 230 to the internal space 201 of electrical device 200, then from the internal space 201 of electrical device 200 to first air outlet 220 and from first air outlet 220 to receiving cavity 400. Fan 210 then draws in air Q from receiving cavity 400, causing air Q to enter the internal space 201 of electrical device 200 from second air outlet 230, thereby forming airflow circulation channel 20. In this application, the airflow circulation channel 20 is formed by the fan 210 of electrical device 200 itself, eliminating the need for an additional fan, saving costs, and saving internal space of receiving cavity 400 without occupying other space.

[0119] The heat control device 300 includes a first heat exchanger 310, a second heat exchanger 320, and a heat exchange medium 330 (e.g., Figure 4a As shown, the first heat exchanger 310 and the second heat exchanger 320 are connected by a pipe 303. The heat exchange medium 330 is located in the first heat exchanger 310 and the second heat exchanger 320 and can flow between the first heat exchange pipe 310 and the second heat exchange pipe 320. The first heat exchanger 310 and the second heat exchanger 320 realize heat exchange inside and outside the casing 100 through the heat circulation of the heat exchange medium 330. The first heat exchanger 310 is located in the receiving cavity 400 and is adjacent to the first air outlet 220.

[0120] The first heat exchanger 310 and the second heat exchanger 320 are components capable of conducting heat and can be air-liquid heat exchangers. The heat exchange medium 330 can change from a first state to a second state when it absorbs sufficient heat, and can change from a second state to a first state when it releases heat, thereby realizing a heat cycle. For example, when the heat exchange medium 330 absorbs sufficient heat, it changes from a liquid to a gas, and when it releases sufficient heat, it changes from a gas to a liquid. The heat exchange medium 330 is a refrigerant, such as water, ethylene glycol, acetone, methanol, etc.

[0121] In one embodiment, when the electrical device 200 needs to be cooled, the heat generated by the operation of the electrical device 200 causes the air in the containment cavity 400 to heat up through the airflow circulation channel 20. The first heat exchanger 310 located in the containment cavity 400 absorbs the heat of the air in the containment cavity 400 and transfers the heat to the heat exchange medium 330 in the first heat exchanger 310. After absorbing the heat, the heat exchange medium 330 heats up and vaporizes into a gas. The gaseous heat exchange medium 330 flows to the second heat exchanger 320, whereby the second heat exchanger 320 is used to transfer the heat of the gaseous heat exchange medium 330 to the outside of the housing 100, thereby realizing the inside-outside heat exchange process of transferring the heat inside the housing 100 to the outside of the housing 100.

[0122] In one embodiment, when the electrical device 200 needs to be heated, for example when the chassis 10 is located in an extremely cold region and the internal temperature of the electrical device 200 is too low to reach the normal operating temperature, the electrical device 200 needs to be heated to ensure its normal operation. The second heat exchanger 320 heats the heat exchange medium 330 in the second heat exchanger 320. The heated heat exchange medium 330 flows to the first heat exchanger 310, and the heat of the heat exchange medium 330 is transferred to the air in the receiving cavity 400 through the first heat exchanger 310. The heated air in the receiving cavity 400 heats the electrical device 200 through the airflow circulation channel 20, thereby realizing an outside-to-inside heat exchange process that transfers heat from the outside of the casing 100 to the inside of the casing 100.

[0123] The internal-to-external and external-to-internal heat exchange processes are achieved by the thermal circulation of the heat exchange medium 330 between the first heat exchanger 310 and the second heat exchanger 320. The first heat exchanger 310 is located in the receiving cavity 400 and is used to achieve heat exchange between the air inside the receiving cavity 400 and the heat exchange medium 330 within the first heat exchanger 310. The heat exchange medium 330 can flow from the first heat exchanger 310 to the second heat exchanger 320. The installation position of the second heat exchanger 320 can be arbitrarily set, as long as heat exchange between the heat exchange medium 330 within the second heat exchanger 320 and the outside of the casing 100 is achieved. Figure 4a In the illustrated configuration, the housing 100 includes a top cover 130 and a bottom plate 140 disposed opposite each other along a first direction Y. The second heat exchanger 320 is located in the top cover 130 of the housing 100, wherein the first direction Y is the height direction of the housing 10. In some embodiments, the second heat exchanger 320 is located on the side of the housing 100.

[0124] In this application, the first heat exchanger 310 is positioned adjacent to the first air outlet 220 (e.g., Figure 4aAs shown, the airflow Q entering the internal space 201 of the electrical device 200 from the first air vent 220 will pass through the first heat exchanger 310, or the airflow Q exiting the internal space 201 of the electrical device 200 from the first air vent 220 will pass through the first heat exchanger 310, so that the air Q in the internal space 201 of the electrical device 200 can exchange heat with the first heat exchanger 310 in a timely manner, thereby improving the heat exchange efficiency of the electrical device 200. For example, when it is necessary to cool down the electrical device 200, assuming the first air vent 220 is the air inlet, the electrical device 200 generates heat during operation, the fan 210 operates, driving the cold air Q cooled by the first heat exchanger 310 to quickly enter the internal space 201 of the electrical device 200 from the first air vent 220, thus timely cooling down the electrical device 200. This reduces the transport distance of the cold air Q from the first heat exchanger 310 to the internal space 201 of the electrical device 200, reducing heat loss and improving the cooling effect on the electrical device 200. Here, the electrical device 200 is the heat source that generates heat, and the first heat exchanger 310 is the cold source that cools the electrical device 200. Placing the heat source (electrical device 200) and the cold source (first heat exchanger 310) adjacent to each other provides a better heat exchange effect, thereby improving the heat dissipation efficiency of the electrical device 200.

[0125] If the first heat exchanger 310 is positioned far from the first air outlet 220, when cooling of the electrical device 200 is required, the first heat exchanger 310 will first cool the components or air near it. The cooled components or air near the first heat exchanger 310 will then exchange heat with other components or air further away, resulting in heat loss. For example, some cold air may exchange heat with the inner wall of the housing 100 to cool the housing 100, while the cooled housing 100 will exchange heat with the outside air through its outer wall. In other words, some cold air is used to cool the outside air, resulting in heat loss and reducing the efficiency of the heat control device 300 in cooling the electrical device 200. In this application, the first heat exchanger 310 is positioned near the first air outlet 220, so that the first heat exchanger 310 can cool the air passing through the first air outlet 220 to the maximum extent, reducing heat loss. When the first air vent 220 is an air inlet, the air cooled by the first heat exchanger 310 promptly enters the internal space of the electrical device 200 through the first air vent 220, cooling the components inside the electrical device 200. When the first air vent 220 is an air outlet, the hot air inside the electrical device 200, driven by the fan 210, passes through the first air vent 220 and is promptly cooled by the first heat exchanger 310. The cooled air then re-enters the internal space 201 of the electrical device 200 through the airflow circulation channel 20 via the second air vent 230, cooling the components in the internal space 201 of the electrical device 200, thus improving the cooling effect of the electrical device 200 and also enhancing the cooling efficiency of the heat control device 300 for the electrical device 200.

[0126] If the first heat exchanger 310 is positioned far from the first air outlet 220, when heating the electrical device 200 is required, the first heat exchanger 310 will first heat the components or air near it. The heated components or air near the first heat exchanger 310 will then exchange heat with other components or air at a distance, resulting in heat loss. For example, some hot air will exchange heat with the inner wall of the housing 100 to heat the housing 100, while the heated housing 100 will also exchange heat with the outside air through its outer wall. In other words, some hot air is used to heat the outside air, causing heat loss and reducing the efficiency of the heat control device 300 in heating the electrical device 200. In this application, the first heat exchanger 310 is positioned near the first air outlet 220, so that the first heat exchanger 310 heats the air passing through the first air outlet 220 to the maximum extent, reducing heat loss. When the first air vent 220 is an air inlet, the air heated by the first heat exchanger 310 promptly enters the internal space of the electrical device 200 through the first air vent 220, heating the components inside the electrical device 200. When the first air vent 220 is an air outlet, the cold air inside the electrical device 200, driven by the fan 210, passes through the first air vent 220 and is promptly heated by the first heat exchanger 310. The heated air then re-enters the internal space 201 of the electrical device 200 through the airflow circulation channel 20 via the second air vent 230, heating the components in the internal space 201 of the electrical device 200, thus improving the heating effect of the electrical device 200 and also enhancing the heating efficiency of the heat control device 300 on the electrical device 200.

[0127] The fan 210 is the fan of the electrical device 200 itself, and is generally installed inside the electrical device 200 or in the first air vent 220 and the second air vent 230 of the electrical device 200. That is to say, the fan 210 is closer to the first air vent 220, and the airflow and velocity through the first air vent 220 are the largest. When this airflow and velocity pass through the first heat exchanger 310, the air volume that exchanges heat with the first heat exchanger 310 per unit time is larger, thus improving the heat exchange efficiency. If the fan 210 is placed further away from the electrical device 200, the airflow driven by the fan 210 is dispersed in the receiving cavity 400, and the airflow and velocity reaching the first heat exchanger 310 will be reduced, thus reducing the heat exchange efficiency of the first heat exchanger 310.

[0128] Please see Figure 5 When an integrated air conditioner 30 is installed inside the chassis 10 to cool the electrical device 200, the integrated air conditioner 30 refers to the air conditioner indoor unit and the air conditioner outdoor unit being an integrated structure. The integrated air conditioner 30 is relatively large, which will increase the internal size of the chassis 10 and has a poor heat dissipation effect on the electrical device 200.

[0129] like Figure 5 As shown, the integrated air conditioner 30 includes an air conditioner housing 31 and an air conditioner fan 32, an evaporator 33, and an air conditioner outdoor unit assembly 36 located in the air conditioner housing 31. The air conditioner housing 31 includes an air outlet 34 and an air inlet 35, with a certain distance between the air outlet 34 and the air inlet 35. Generally, the air outlet 34 and the air inlet 35 on the air conditioner housing 31 are located at the upper and lower ends of the air conditioner housing 31, respectively. The evaporator 33 is used to cool the air entering the air conditioner housing 31. The cooled air is discharged from the air outlet 34 into the receiving cavity 400. The air conditioner outdoor unit assembly 36 is used to transfer the heat of the evaporator 33 to the outside of the housing 100. When the integrated air conditioner 30 is used to cool the electrical device 200, the cold air cooled by the evaporator 33 flows from the air outlet 34 into the receiving cavity 400. There is a cold loss in the cold air between the air outlet 34 and the electrical device 200, and then the air dissipates heat to the electrical device 200. In this heat dissipation method, the evaporator 33 used to cool the hot air is located inside the air conditioner housing 31. The air path distance between the evaporator 33 and the electrical device 200 is relatively far. The hot air generated by the heat inside the electrical device 200 cannot be cooled near the first air outlet 220 of the electrical device 200. The hot air needs to travel a long path to reach the evaporator 33. The heat of the hot air will be transferred to other spaces in the receiving cavity 400. The airflow of the hot air reaching the evaporator 33 is reduced, and the heat dissipation efficiency of the evaporator 33 for the electrical device 200 is reduced. The heat dissipation efficiency is lower than that of the first heat exchanger 310 for the electrical device 200 when the first heat exchanger 310 is placed near the first air outlet 220 in this application.

[0130] Please see Figure 6 When a split-type air conditioner is used to cool the electrical device 200, an indoor unit 40 is installed inside the casing 10, and an outdoor unit 50 is installed outside the casing 10. The indoor unit 40 blows cold air to cool the housing 400 and the electrical device 200. The indoor unit 40 includes an air conditioner housing 41 and an air conditioner fan 42 and an evaporator 43 located within the housing 41. The indoor unit 40 is also relatively large, increasing the internal dimensions of the casing 10. The air conditioner housing 41 includes an air outlet 44 and an air inlet 45. In this embodiment, the evaporator 43 is far from the electrical device 200, resulting in some cold loss and poor heat dissipation for the electrical device 200. Furthermore... Figure 5 and Figure 6 In both of the methods shown, a fan needs to be installed inside the air conditioner, which increases the cost, while no additional fan is required in this application.

[0131] In this application, the fan 210 of the electrical device 200 itself is used to achieve air circulation between the internal space 201 of the electrical device 200 and the receiving cavity 400, eliminating the need for an additional fan, saving costs and space in the receiving cavity 400. Furthermore, the first heat exchanger 310 is positioned adjacent to the first air outlet 220 of the electrical device 200, enabling the first heat exchanger 310 to exchange heat with the electrical device 200 in a timely manner, thereby improving the heat exchange effect on the electrical device 200 and enhancing the heat exchange efficiency of the heat control device 300 on the electrical device 200.

[0132] The first heat exchanger 310 may include a first heat exchange tube 301. Alternatively, the first heat exchanger 310 may include a first heat exchange tube 301 and a heat-conducting fin 302 (e.g., Figure 4a As shown, the first heat exchange tube 301 passes through the heat-conducting fin 302, which increases the contact area for heat exchange between the air and the heat exchanger. The first heat exchanger 310 can also be other structural components; for example, when the first heat exchanger 310 is used to cool air, it can be an evaporator.

[0133] Please continue reading. Figure 4a In one possible implementation, the electrical device 200 includes a housing 241 and an electrical component 202 located in the housing 241. The housing 241 includes the first air vent 220 and the second air vent 230. The fan 210 is located at at least one of the following locations: the first air vent 220, the second air vent 230, and the interior space of the housing 241.

[0134] The housing 241 refers to the housing used to house the electrical component 202, which is the electrical component 202 of the electrical device 200. The housing 241 and the electrical component 202 located in the housing 241 constitute the electrical compartment 240. When the electrical device 200 is a battery module, the housing 241 is a housing used to house the battery cells; when the electrical device 200 is a server, the housing 241 is a housing used to house electronic components. In this embodiment, the electrical device 200 is a battery module, and the housing 241 and the battery cells 202 located therein constitute the battery compartment.

[0135] In this embodiment, the first air vent 220 and the second air vent 230 are arranged opposite each other along the second direction X (e.g., Figure 4a As shown), the second direction X intersects the first direction Y. The first air vent 220 is the air inlet, the second air vent 230 is the air outlet, and the fan 210 is located at the first air vent 220 (as shown). Figure 4aAs shown in the diagram, the air that exchanges heat with the first heat exchanger 310 is blown directly into the internal space 201 of the housing 241 from the first air vent 220, and then exchanges heat with the electrical components 202, thereby improving heat exchange efficiency. In some embodiments, the first air vent 220 is an air outlet, and the second air vent 230 is an air inlet. The air exiting the internal space 201 of the housing 241 directly exchanges heat with the first heat exchanger 310 after exiting from the first air vent 220.

[0136] In one embodiment, the fan 210 may also be located inside the housing 241 (e.g., Figure 7 As shown), the internal space of the housing 241 is the internal space 201 of the electrical device 200. The fan 210 can be located at any position on the housing 241. Specifically, the fan 210 can be set according to the arrangement of the electrical components 202 to ensure a reasonable layout of the fan 210 and the electrical components 202, guaranteeing ventilation volume and the number of electrical components 202. In one embodiment, the fan 210 can be located at the second air vent 230 (e.g., Figure 8 (As shown). In one embodiment, there are two fans 210, which are respectively located in the first air vent 220 and the second air vent 230 (e.g. Figure 9a (As shown).

[0137] Among them, the fan 210 is located at the first air vent 220, including the fan 310 being fixed to the side of the first air vent 220 facing the internal space of the housing 241 (e.g. Figure 9b (as shown), or the fan 210 is fixed to the side of the first air vent 220 away from the interior space of the housing 241 (as shown). Figure 9c Alternatively, the fan 210 may be fixed to the housing 241 surrounding the first air vent 220. Figure 9d (As shown). Fan 210 is located at the second air vent 230, including fan 310 fixed to the side of the second air vent 230 facing the interior space of the housing 241 (e.g. Figure 9e Alternatively, the fan 210 can be fixed to the side of the second air vent 230 away from the interior space of the casing 241 (e.g., Figure 9f (as shown), or the fan 210 is fixed to the housing 241 around the second air vent 230 (as shown). Figure 9g (As shown).

[0138] In one embodiment, the electrical device 200 includes a plurality of fans 210, which are respectively located at a first air outlet 220 and a second air outlet 230 (e.g., Figure 9a (As shown). In one embodiment, a plurality of fans 210 are respectively located at the first air outlet 220 and in the internal space 201 of the housing 241 (as shown). Figure 9h (As shown). In one embodiment, a plurality of fans 210 are respectively located at the second air vent 230 and in the internal space 201 of the housing 241 (as shown). Figure 9i (As shown). In one embodiment, a plurality of fans 210 are respectively located at the first air vent 220, the second air vent 230, and the internal space 201 of the housing 241 (as shown). Figure 9j (As shown). The arrangement of multiple fans 210 can increase airflow speed.

[0139] Please continue reading. Figure 4a In this embodiment, when the heat control device 300 is used to cool the electrical compartment 240, the fan 210 drives the air Q cooled by the first heat exchanger 310 to flow from the first air outlet 220 to the internal space of the compartment shell 241 to cool the electrical components 202. The air Q heats up and then flows from the second air outlet 230 to the receiving cavity 400. Through the airflow circulation channel 20, the air Q returns to the first air outlet 220 and is cooled by the first heat exchanger 310. The cooled air Q then re-enters the internal space of the compartment shell 241, which can effectively improve the cooling efficiency of the electrical components 202 inside the compartment shell 241.

[0140] In some embodiments, the heat control device 300 can be used to heat the electrical compartment 240. The specific heating process is similar to the heating process described above and will not be repeated here.

[0141] In this embodiment, the housing 100 includes a first side door 110 (e.g., Figure 4a As shown, the first air vent 220 faces the first side door 110, and the first heat exchanger 310 is located between the first side door 110 and the first air vent 220, and is fixed to the inner surface of the first side door 110 facing the electrical device 200. Installing the first heat exchanger 310 on the first side door 110 facilitates maintenance of both the first heat exchanger 310 and the electrical device 200; maintenance of the first heat exchanger 310 can be performed simply by opening the first side door 110.

[0142] In other embodiments, the first heat exchanger 310 may also be fixed to the outside of the electrical device 200 (e.g., Figure 4b (As shown). The housing 100 includes a first side door 110, which is located on one side of the electrical device 200 along the second direction X. The first air vent 220 and the second air vent 230 are arranged opposite each other along the second direction X. The first side door 110 is located closer to the second air vent 230 than the first air vent 220. The first heat exchanger 310 is fixed to the outside of the electrical device 200.

[0143] In some embodiments, a plurality of first heat exchangers 310 are also provided on other sides of the electrical device 200 to improve the heat exchange effect on the electrical device 200.

[0144] Please see Figure 10In one possible implementation, the electrical device 200 includes a plurality of stacked housings 241. In each housing 241, a first heat exchanger 310 is located outside a first air vent 220, and at least a portion of the first heat exchanger 310 is opposite to the first air vent 220. In this embodiment, the housing 100 also includes a top cover 130 and a bottom plate 140 disposed opposite each other along a first direction Y. The electrical device 200 is located in the area between the top cover 130 and the bottom plate 140, and the plurality of housings 241 are stacked in the first direction Y. The first heat exchanger 310 extends along the first direction Y, such that each housing 241 has a portion of the first heat exchanger 310 at its first air vent 220, allowing for more uniform heat dissipation for each electrical housing 240. In this embodiment, the first direction Y is the height direction of the housing 100, and the second direction X is the width direction of the housing 100.

[0145] When the integrated air conditioner 30 is used to dissipate heat from the electrical device 200 in this embodiment (e.g.) Figure 11 As shown, the air outlet of the integrated air conditioner 30 is generally located at a high position. After the cold air Q comes out of the air outlet 34 of the integrated air conditioner 30 and flows into the receiving cavity 400, the flow rate of the cold air Q gradually decreases from top to bottom, and the temperature of the cold air Q gradually increases from top to bottom. This makes the heat dissipation effect of the cold air Q on the electrical compartment 240 at the top and the electrical compartment 240 at the bottom of the electrical device 200 inconsistent. The heat dissipation effect of the electrical compartment 240 from the top to the bottom of the electrical device 200 gradually worsens, resulting in uneven heat dissipation.

[0146] In this embodiment, a portion of the first heat exchanger 310 is provided at the first air vent 220 of each chamber shell 241. When cooling the electrical device 200, the heat exchange medium 330 in the first heat exchanger 310 is liquid. The liquid absorbs heat and turns into gas. The difference in the amount of heat absorbed by the liquid heat exchange medium 330 at any position in the first heat exchanger 310 as it turns from liquid to gas is small. In this embodiment, a large amount of liquid heat exchange medium 330 can be provided in the first heat exchanger 310 so that the liquid heat exchange medium 330 can flow to any part of the first heat exchanger 310, or at least to the portion of the first heat exchanger 310 adjacent to the first air vent 220 of each chamber shell 240. This makes the heat absorption effect of the portion of the first heat exchanger 310 adjacent to the first air vent 220 of each chamber shell 241 comparable, thereby improving the heat dissipation uniformity of each electrical chamber 240 in the electrical device 200.

[0147] In one embodiment, the electrical device 200 includes an electrical support 250 (e.g., Figure 12 As shown, multiple electrical compartments 240 are mounted on an electrical support 250, wherein the structure of the electrical support 250 is not limited to... Figure 12 The structure shown can also be other structures. In some embodiments, multiple electrical compartments 240 can be directly stacked along the first direction Y.

[0148] Please see Figure 13 In some embodiments, the electrical device 200 includes a device housing 260 and electrical components 202 located within the device housing 260. The device housing 260 includes a first air vent 220 and a second air vent 230. The fan 210 is located at at least one of the following locations: the first air vent 220, the internal space of the device housing 260, or the second air vent 230. When the electrical device 200 is a battery module 200, the battery module 200 includes a module housing 260 and battery cells 202 located within the module housing 260. The battery cells 202 are directly disposed within the module housing 260. The module housing 260 includes a first air vent 220 and a second air vent 230. The fan 210 is located at at least one of the following locations: the first air vent 220, the internal space of the device housing 260, or the second air vent 230.

[0149] The first air vent 220 and the second air vent 230 are respectively disposed on the housing 260 of the device housing, which is arranged opposite to each other along the second direction X. The fan 210 is fixed to the device housing 260 by means of clips, screws, etc., and the specific method is not limited. When the electrical device 200 includes multiple electrical components 202 arranged along the first direction Y (e.g., Figure 13 As shown, multiple electrical components 202 can be arranged along the first direction Y by means of brackets or stacking, and multiple first air vents 220, multiple second air vents 230 and multiple fans 210 are provided on the housing of the device housing 260 along the second direction X, so that each electrical component 202 has a first air vent 220 and a second air vent 230 on both sides along the second direction X, and has a fan 210 that can blow air directly onto the electrical component 202.

[0150] Please see Figure 14 In one possible implementation, the chassis 10 includes a plurality of electrical devices 200 arranged in an array, and the heat control device 300 includes a plurality of first heat exchangers 310. Each of the plurality of electrical devices 200 has a first heat exchanger 310 at the location of its first air vent 220. The plurality of electrical devices 200 are arranged in a third direction Z, which intersects with both a second direction X and a first direction Y. In this embodiment, the first direction Y is the height direction of the chassis 100, the second direction X is the width direction of the chassis 100, and the third direction Z is the length direction of the chassis 100.

[0151] In this embodiment, the electrical device 200 has multiple (such as) Figure 14 As shown), the electrical device 200 has multiple electrical compartments 240 (such as...). Figure 10 As shown, when the first heat exchanger 310 is used to cool multiple electrical devices 200, a portion of the first heat exchanger 310 is provided at the first air vent 220 of each electrical compartment 240 in each electrical device 200. This improves the heat dissipation effect on each electrical compartment 240 and enhances the heat dissipation uniformity across all electrical devices 200. In this embodiment, the number of electrical devices 200 arranged in the third direction Z is unlimited; even with a large number of electrical devices 200, good heat dissipation uniformity is still achieved. When the first heat exchanger 310 is used to heat multiple electrical devices 200, good heating uniformity is achieved.

[0152] When the integrated air conditioner 30 is used to dissipate heat from the electrical device 200 in this embodiment (e.g.) Figure 15 As shown, the air outlet of the integrated air conditioner 30 is generally located at one end of the casing 100. This results in poor heat dissipation for electrical devices 200 located far from the integrated air conditioner 30 compared to those closer to it, leading to poor overall heat dissipation uniformity. To improve heat dissipation uniformity, multiple integrated air conditioners 30 would need to be installed in multiple locations within the casing 100, increasing costs and occupying more space. Furthermore, installing multiple integrated air conditioners 30 on the first side door 110 increases the risk of damage due to its weight, resulting in high maintenance costs. This application uses a method where the first heat exchanger 310 is located near the first air outlet 220, which is cost-effective and saves space. When heating multiple electrical devices 200, this application provides a portion of the first heat exchanger 310 near the first air outlet 220, improving the heat exchange uniformity for all electrical devices 200.

[0153] When multiple first heat exchangers 310 are present, the heat control device 300 may include one or more second heat exchangers 320. When there is only one second heat exchanger 320, it is connected to multiple first heat exchangers 310 for heat exchange of the heat exchange medium 330 in the multiple first heat exchangers 310. When there are multiple second heat exchangers 320, each second heat exchanger 320 may be connected to multiple first heat exchangers 310 respectively for heat exchange of the heat exchange medium 330 in the multiple first heat exchangers 310, and the specific configuration can be determined according to actual needs.

[0154] In some embodiments, the chassis 10 includes a plurality of electrical devices 200 arranged along a second direction X, and a first heat exchanger 310 is provided on the outside of each electrical device 200. The number of first heat exchangers 310 can be increased according to the number or distribution of the electrical devices 200. The distributed layout of multiple first heat exchangers can dissipate heat from each electrical device 200, thereby improving the heat dissipation effect.

[0155] Please refer to 14. In one embodiment, two electrical devices 200 are arranged along the second direction X, referred to as electrical device 200a and electrical device 200b respectively. The housing 100 also includes a second side door 120 disposed opposite to the first side door 110. Electrical device 200a is disposed adjacent to the first side door 110, and electrical device 200b is disposed adjacent to the second side door 120. A first heat exchanger 310a is fixed on the inner surface of the first side door 110 adjacent to electrical device 200a. The first air vent 220 of electrical device 200a is disposed closer to the first side door 110 than the second air vent 230. The first heat exchanger 310a performs heat exchange on electrical device 200a. A first heat exchanger 310b is fixed on the inner surface of the second side door 120 near the electrical device 200b. Compared with the second air vent 230, the first air vent 220 of the electrical device 200b is located closer to the second side door 120. The first heat exchanger 310b exchanges heat with the electrical device 200b. That is, the first air vents 220 of the two electrical devices 200 arranged along the second direction X are respectively near the first side door 110 and the second side door 120 on both sides.

[0156] Please see Figure 16 In one embodiment, two electrical devices 200 are arranged along the second direction X, respectively referred to as electrical device 200c and electrical device 200d. The housing 100 includes a second side door 120 disposed opposite to the first side door 110, wherein electrical device 200c is disposed adjacent to the first side door 110 and electrical device 200d is disposed adjacent to the second side door 120. A first heat exchanger 310c is fixed on the surface of electrical device 200c away from the first side door 110. The first air vent 220 of electrical device 200c is positioned away from the first side door 110 and adjacent to the first heat exchanger 310c compared to the second air vent 230. The first heat exchanger 310c exchanges heat with electrical device 200c. A first heat exchanger 310d is fixed on the surface of electrical device 200d away from the second side door 120. The first air vent 220 of electrical device 200d is positioned away from the second side door 120 compared to the second air vent 230. The first heat exchanger 310d exchanges heat with electrical device 200d. In other words, the first air vents 220 of two electrical devices 200 are arranged along the second direction X, respectively away from the first side door 110 and the second side door 120 on both sides.

[0157] In some embodiments, two or more electrical devices 200 are arranged along the second direction X. In this case, the first heat exchanger 310 of the electrical device 200 located between the electrical devices 200a and 200b can be fixed to the electrical device 200.

[0158] In one possible implementation, the heat control device 300 further includes a flow guide housing 340 (e.g., Figure 17aAs shown), the flow guide housing 340 and the first heat exchanger 310 are located on the same side of the electrical device 200 along the second direction X, and the flow guide housing 340 and the first heat exchanger 310 extend along the first direction Y (as shown). Figure 1 As shown), the second direction X intersects the first direction Y. The first heat exchanger 310 is located inside the flow guide shell 340. The flow guide shell 340 is provided with a third air outlet 341 and a fourth air outlet 342. Compared with the fourth air outlet 342 (as shown), Figure 17a As shown), the third air vent 341 is located closer to the first air vent 220. The third air vent 341 and the first air vent 220 are used to connect the internal space of the flow guide housing 340 and the internal space of the electrical device 200. The fourth air vent 342 is used to connect the internal space of the flow guide housing 240 and the receiving cavity 400.

[0159] The third air vent 341 and the fourth air vent 342 are located within the airflow circulation channel 20. When the first air vent 220 is the air outlet of the electrical device 200 and the second air vent 230 is the air inlet of the electrical device 200, the third air vent 341 is the air inlet of the guide housing 340 and the fourth air vent 342 is the air outlet of the guide housing 340. The air coming out of the first air vent 220 passes through the third air vent 341 and enters the internal space of the guide housing 340, where it is cooled by the first heat exchanger 310. The guide housing 340 allows the air to stay briefly in its receiving hole, thus increasing the contact time between the air and the first heat exchanger 310 and enabling sufficient heat exchange.

[0160] In one embodiment, the central axis of the third air vent 341 overlaps with that of the first air vent 220, making the airflow between the first air vent 220 and the third air vent 341 smoother.

[0161] In one embodiment, the flow guide housing 340 includes a first side plate 343, a second side plate 344, a third side plate 345, and a fourth side plate 346 (e.g., Figure 17a As shown in the figure, the first side plate 343 and the second side plate 344 are arranged opposite each other along the second direction X, and the third side plate 345 and the fourth side plate 346 are arranged opposite each other along the third direction Z. The first side plate 343, the third side plate 345, the second side plate 344 and the fourth side plate 346 are connected in sequence to form a flow guide shell 340. The first side plate 343 is arranged adjacent to the first air outlet 220, the third air outlet 341 is arranged on the first side plate 343, and the fourth air outlet 342 is provided on both the third side plate 345 and the fourth side plate 346. The air entering from the third air outlet 341 can be divided into two paths and discharged from the fourth air outlet 342 on the third side plate 345 and the fourth side plate 346 respectively.

[0162] In one embodiment, the housing 100 further includes a top cover 130 and a bottom plate 140 disposed opposite each other along the first direction Y (e.g., Figure 1(As shown), the flow guide housing 340 is located between the top cover 130 and the bottom plate 140. Please refer to... Figure 17b and Figure 17c , Figure 17c yes Figure 17b A schematic diagram of the unfolded flow guide housing 340 is shown. The flow guide housing 340 includes a third air vent 341 and a fourth air vent 342. The maximum vertical distance h1 between the edge of the third air vent 341 and the base plate 140 is greater than the minimum vertical distance h2 between the edge of the fourth air vent 342 and the base plate 140, and less than or equal to the maximum vertical distance h3 between the edge of the fourth air vent 342 and the base plate 140. This allows air to flow from the third air vent 341 to the fourth air vent 342, or from the fourth air vent 342 to the third air vent 341, increasing the airflow speed while ensuring sufficient heat exchange. The first direction Y is perpendicular to the base plate 140.

[0163] Please see Figure 17d and Figure 17e , Figure 17e yes Figure 17d A schematic diagram of the unfolded flow guide housing 340. In one embodiment, the maximum vertical distance h3 between the edge of the fourth air vent 342 and the base plate 140 is greater than the minimum vertical distance h4 between the edge of the third air vent 341 and the base plate 140, and less than or equal to the maximum vertical distance h1 between the edge of the third air vent 341 and the base plate 140, and the first direction Y is a direction perpendicular to the base plate 140.

[0164] In one embodiment, the vertical distances between the upper and lower edges of the third air vent 341 and the fourth air vent 342 and the base plate 140 are respectively equal (e.g., Figure 17f As shown), specifically, the maximum vertical distance h1 between the edge of the third air vent 341 and the base plate 140 is equal to the maximum vertical distance h3 between the edge of the fourth air vent 342 and the base plate 140, and the minimum vertical distance h4 between the edge of the third air vent 341 and the base plate 140 is equal to the minimum vertical distance h2 between the edge of the fourth air vent 342 and the base plate 140.

[0165] In one embodiment, the fourth air vent 342 is two (e.g. Figure 17a As shown), in one embodiment, the fourth air vent 342 is three (as shown). Figure 17g (As shown).

[0166] In one embodiment, the third air vent 341 and the fourth air vent 342 are rectangular in shape, and the length direction of the rectangle is the same as the first direction Y (e.g., Figure 17h (As shown). In one embodiment, the third air vent 341 and the fourth air vent 342 are square in shape (e.g., ...). Figure 17i(As shown). In one embodiment, the third air vent 341 and the fourth air vent 342 are elliptical in shape (as shown). Figure 17j (as shown). In one embodiment, when there are two or more fourth air vents 342, the maximum vertical distance between the upper edge of each fourth air vent 342 and the base plate 140 may be the same or different, the minimum vertical distance between the lower edge of each fourth air vent 342 and the base plate 140 may be the same or different, and the shape of each fourth air vent 342 may be the same or different.

[0167] In one embodiment, when the electrical device 200 includes a plurality of housings 241 (e.g. Figure 17k As shown, the airflow guide housing 340 is provided with a plurality of third air vents 341, each third air vent 341 being disposed opposite to a first air vent 220 of a housing 241, and at least one fourth air vent 342 satisfying the above-mentioned vertical distance relationship with one of the third air vents 341. In this embodiment, the airflow guide housing 340 provides one third air vent 341 and one fourth air vent 342 for each housing 241.

[0168] In one embodiment, a water receiving tray and a water pump are provided at the bottom of the flow guide housing 340. The water receiving tray is used to collect water droplets condensed from the first heat exchanger 310, and the water in the water receiving tray is discharged from the housing 100 by the water pump.

[0169] Please see Figure 18 In one possible implementation, the housing 100 further includes a top cover 130 and a bottom plate 140 disposed opposite each other along a first direction Y. The electrical device 200 is located on the bottom plate 140, and the top cover 130 has a receiving space 131, in which the second heat exchanger 320 is located. Placing the second heat exchanger 320 in the top cover 130 saves space. The bottom plate 140 has multiple fixed supports 142, and slide rails 141 are provided on the fixed supports 142. The electrical device 200 is located on the slide rails 141. When there are multiple electrical devices 200, there are multiple first heat exchangers 310 and multiple second heat exchangers 320. These multiple second heat exchangers 320 are concentrated in the top cover 130 to save on the size of the housing 10. In other embodiments, the second heat exchanger 320 may also be disposed in the side shell of the housing 100 or on the outside of the housing 100.

[0170] In one embodiment, the inlet 311 and outlet 312 of the first heat exchanger 310 are located at one end of the first heat exchanger 310 adjacent to the top cover 130. The inlet 311 and outlet 312 of the first heat exchanger 310 may include multiple “S” loop sections or a “U” loop section between the inlet 311 and outlet 312.

[0171] When the inlet 311 and outlet 312 form a U-shaped loop, the heat exchange uniformity of the electrical device 200 can be improved. The U-shaped first heat exchanger 310 includes an inlet section 313 and an outlet section 314 (e.g., Figure 19 As shown), the inlet of the liquid inlet section 313 is the inlet 311 of the first heat exchanger 310. The outlet 315 of the liquid inlet section 313 is connected to the inlet 316 of the liquid outlet section 314. The outlet of the liquid outlet section 314 is the outlet 312 of the first heat exchanger 310. The outlet 315 of the liquid inlet section 313 and the inlet 316 of the liquid outlet section 314 are located at the bottom of the "U"-shaped loop. When the heat control device 300 is used to dissipate heat from the electrical device 200, the cooled liquid heat exchange medium 330 flows from the second heat exchanger 320 into the first heat exchanger 310. The liquid heat exchange medium 330 enters from the inlet 311. For the inlet section 313: the liquid heat exchange medium 330 near the inlet 311 of the inlet section 313 has a higher liquid content, while the liquid heat exchange medium near the outlet 315 of the inlet section 313 has a relatively lower liquid content. This means that the heat dissipation effect is better at the inlet 311 of the inlet section 313 than at the outlet 315. For the outlet section 314: the liquid heat exchange medium 330 near the inlet 316 of the outlet section 314 has a higher liquid content, while the liquid heat exchange medium near the outlet 312 of the outlet section 314 has a lower liquid content. The content of heat transfer fluid 330 is relatively low, which means that the inlet 316 part of the outlet section 314 has a better heat dissipation effect than the outlet 312 part of the outlet section 314. The inlet 316 part of the outlet section 314 is adjacent to the outlet 315 part of the inlet section 313, and the outlet 312 part of the outlet section 314 is adjacent to the inlet 311 part of the inlet section 313. This allows the two ends of the inlet section 313 and the outlet section 314 to compensate for each other, thereby making the heat dissipation effect of the entire first heat exchanger 310 on the upper and lower parts of the electrical device 200 more uniform.

[0172] When there are multiple "S"-shaped loops between the inlet 311 and the outlet 312, the multiple "S"-shaped loops are equivalent to having multiple "U"-shaped loops as described above, which can also improve the heat dissipation uniformity of the first heat exchanger 310 to the upper and lower parts of the electrical device 200.

[0173] Please continue reading. Figure 10In one possible implementation, pipe 303 further includes a first connecting pipe 350 and a second connecting pipe 360. The first connecting pipe 350 connects between the inlet of the first heat exchanger 310 and the outlet of the second heat exchanger 320, and is connected to both the first heat exchanger 310 and the second heat exchanger 320. The second connecting pipe 320 connects between the outlet of the first heat exchanger 310 and the inlet of the second heat exchanger 320, and is connected to both the first heat exchanger 310 and the second heat exchanger 320. When the first heat exchanger 310 is mounted on the first side door 110, the first side door 110 can be opened smoothly via the first connecting pipe 350 and the second connecting pipe 360. In one embodiment, the first connecting pipe 350 and the second connecting pipe 360 ​​are connecting pipes with elastic expansion and contraction capabilities, or the first connecting pipe 350 and the second connecting pipe 360 ​​have a certain length, allowing the first side door 110 to be opened more smoothly.

[0174] Please continue reading. Figure 18 In one embodiment, the second heat exchanger 320 includes a second heat exchange tube 321, a compressor 322, an expansion valve 323, a heat exchange component 324, and an outdoor fan 325. The compressor 322, the heat exchange component 324, and the expansion valve 323 are sequentially connected between the inlet 311 and the outlet 312 of the first heat exchanger 310. A portion of the second heat exchange tube 321 is between the compressor 322 and the heat exchange component 324. The heat exchange component 324 and the expansion valve 323 also have portions of the second heat exchange tube 321. The compressor 322, the heat exchange component 324, and the expansion valve 323 are in communication with the second heat exchange tube 321. The heat exchange medium 330 flows in the second heat exchange tube 321, the compressor 322, the expansion valve 323, and the heat exchange component 324. The outdoor unit fan 325 is used to drive the external circulation between the internal space of the top cover 130 and the outside of the housing 100. The top cover 130 includes an air inlet 136 and an air outlet 137. After the outdoor unit fan 325 drives the outside air to enter through the air inlet 136, it exchanges heat with the heat exchange component 324 and then exits the top cover 130 through the air outlet 137, so as to realize the external circulation between the internal space of the top cover 130 and the outside of the housing 100.

[0175] Please continue reading. Figure 18When the heat exchange component 324 is a condenser, the condenser is used to cool the heat exchange medium 330 in the second heat exchange tube 321. When the heat control device 300 cools the electrical device 200, the heat exchange medium 330 in the first heat exchanger 310 is a low-pressure, low-temperature liquid. The low-temperature, low-pressure liquid has a lower boiling point and can absorb heat more quickly. The fan 210 in the electrical device 200 drives the internal hot air Q to flow from the first air outlet 220 to the surface of the first heat exchanger 310. The low-pressure, low-temperature liquid heat exchange medium 330 absorbs the heat from the hot air Q and becomes a low-pressure, low-temperature gas heat exchange medium 330. The low-pressure, low-temperature gas heat exchange medium 330 flows from the outlet 312 of the first heat exchanger 310 into the second heat exchange tube 321, and then into the compressor 322. The compressor 322 converts the low-pressure, low-temperature gas heat exchange medium 330 into a high-temperature, high-pressure gas. The high-temperature, high-pressure gaseous heat exchange medium 330 is then introduced into the heat exchange component (condenser) 324 through a portion of the second heat exchange tube 321. The high-temperature, high-pressure gaseous heat exchange medium 330 can refer to a gas with a temperature and pressure higher than that of the outside air. At this time, the outdoor unit fan 325 can be used to drive the outside air to cool down the high-temperature, high-pressure gaseous heat exchange medium 330 in the heat exchange component (condenser) 324. The high-temperature, high-pressure gaseous heat exchange medium 330 is cooled by the heat exchange component (condenser) 324 to form a medium-temperature, high-pressure liquid heat exchange medium 330. The medium-temperature, high-pressure liquid heat exchange medium 330 then enters the expansion valve 323 through a portion of the second heat exchange tube 321, and forms a low-temperature, low-pressure liquid heat exchange medium 330 through the expansion valve 323. The low-temperature, low-pressure liquid heat exchange medium 330 then flows into the first heat exchanger 310 to continue cooling the electrical device 200.

[0176] The second heat exchanger 320 exchanges heat with the heat exchange medium 330 in the first heat exchanger 310, causing the heat exchange medium 330 to form a thermal cycle between the first heat exchanger 310 and the second heat exchanger 320. In this embodiment, the second heat exchanger 320 has a compressor 322 and an expansion valve 323, which allows the temperature of the heat exchange medium 330 to be lowered. When the lower-temperature heat exchange medium 330 exchanges heat with the air in the airflow circulation channel 20 through the first heat exchanger 310 to cool the electrical device 200, the temperature of the electrical device 200 can be kept lower than the external temperature of the casing 100, thereby improving the cooling effect of the electrical device 200. When the heat control device 300 is used to heat the electrical device 200, the second heat exchanger 320 in this embodiment can also be used to keep the temperature of the electrical device 200 higher than the external temperature of the casing 100, thereby improving the heating effect of the electrical device 200.

[0177] In other embodiments, the second heat exchanger 320 may also include other components, such as an air filter, etc., and is not limited to these. Figure 18The structural components described above. The second heat exchanger 320 can also be composed of other structures, as long as it can achieve heat exchange with the heat exchange medium 330 in the first heat exchanger 310.
