Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an outdoor unit. Background Technology

[0002] In related technologies, a refrigerant radiator includes a radiator core for heat exchange with a heat source. The radiator core has fins, and an air duct is formed between two adjacent fins. A heat exchange pipe is connected to or built into the radiator core. A fluid controller is installed in the heat exchange pipe or the pipe connected to it. The fluid controller controls the flow of the cooling medium in the heat exchange pipe based on throttling or one-way shut-off, thereby controlling the main mode of the refrigerant radiator to switch between liquid cooling mode and air cooling mode, so that the refrigerant radiator selects the most suitable heat dissipation method in a suitable environment.

[0003] However, refrigerant radiators cannot achieve convection of hot and cold air inside the casing, cannot evenly distribute heat throughout the entire casing, cannot ensure that all electronic control components operate in a relatively uniform temperature environment, cannot effectively improve the working environment of electronic control components, and are not conducive to improving the overall performance and stability of the equipment. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an outdoor unit that can make the temperature environment of each electronic control component relatively uniform. At the same time, it can reduce the probability of failure caused by factors such as excessive temperature, dust, and moisture, significantly improve the reliability of the equipment, reduce the number of maintenance and downtime, thereby improving production efficiency and reducing operating costs.

[0005] To achieve the above objectives, an outdoor unit is proposed according to an embodiment of the present invention. The outdoor unit includes: a casing; a compressor disposed within the casing; an outdoor heat exchanger disposed within the casing and connected to the compressor; and an electronic control assembly disposed within the casing, comprising: a housing; a circuit board disposed within the housing and electrically connected to the compressor, and having electronic control elements disposed on the circuit board; a refrigerant radiator at least partially disposed within the housing and connected to the outdoor heat exchanger; and fins disposed within the housing and connected to the refrigerant radiator. The electronic control assembly further includes: a fan disposed within the housing; wherein the fins form air ducts, and the fan is disposed opposite to the air ducts. When the cooling energy of the refrigerant radiator is transferred to the fins, the fan operates, and the airflow passes through the air ducts to form a low-temperature airflow within the housing, which convections with the hot air to cool the electronic control elements.

[0006] The above technical solution has the following advantages or beneficial effects: by adopting a fully sealed shell, adding fins to the surface of the refrigerant radiator, and using a fan to circulate air, a low-temperature airflow is formed inside the sealed shell, and hot and cold air convection is carried out, which greatly improves the working environment of the electronic control components and makes the temperature environment of each electronic control component relatively uniform. At the same time, it can reduce the probability of failure caused by factors such as excessive temperature, dust, and moisture, significantly improve the reliability of the equipment, reduce the number of maintenance and downtime, thereby improving production efficiency and reducing operating costs.

[0007] According to some embodiments of the present invention, the fin includes: a heat dissipation portion, wherein there are multiple heat dissipation portions, the multiple heat dissipation portions are spaced apart in a vertical first direction, and an air duct is formed between two adjacent heat dissipation portions. The fan is located on one side of the fin in a vertical second direction, and the vertical first direction is perpendicular to the vertical second direction so that the fan is arranged opposite to the air duct.

[0008] The above technical solution has the following advantages or beneficial effects: the heat dissipation part can play a heat dissipation role and improve the heat conduction efficiency. Multiple heat dissipation parts can further increase the heat exchange area and improve the heat conduction efficiency, so that heat can be dissipated more quickly. The fins can be placed vertically on the refrigerant radiator, and the fan can be placed above or below the refrigerant radiator. In addition, the fins can also be placed horizontally on the refrigerant radiator, and the fan can be placed on the right side to achieve airflow around the radiator. This is conducive to improving the overall performance and stability of the equipment, thereby improving production efficiency and reducing operating costs.

[0009] According to some embodiments of the present invention, the fins further include: a connecting portion, one side of which is connected to the refrigerant radiator, and a plurality of heat dissipation portions are connected to the side of the connecting portion away from the refrigerant radiator.

[0010] The above technical solution has the following advantages or beneficial effects: the connecting part can play a connecting role and realize the connection between the fins and other components. One side of the connecting part is connected to the refrigerant radiator, which realizes the connection between the fins and the refrigerant radiator. The two ends of the connecting part are connected to the heat dissipation part and the refrigerant radiator respectively. Multiple heat dissipation parts are set away from the refrigerant radiator and are spaced apart from each other. This can avoid interference between multiple heat dissipation parts and can quickly dissipate heat.

[0011] According to some embodiments of the present invention, the connecting part is integrally formed on the refrigerant radiator.

[0012] The above technical solution has the following advantages or beneficial effects: the fins can be integrally formed on the refrigerant radiator through the connecting part. At this time, there is no additional joint interface between the fins and the refrigerant radiator, which can reduce the contact thermal resistance and enable heat to be transferred from the refrigerant to the air more efficiently. Secondly, the integrally formed design is usually more robust and durable than the assembled design, and can better resist vibration and other mechanical stresses. At the same time, the integral forming does not require complicated assembly steps, which can reduce production costs and improve production efficiency.

[0013] According to some embodiments of the present invention, the electronic control component further includes a fastener, and the connecting part is fixed to the refrigerant radiator by the fastener.

[0014] The above technical solution has the following advantages or beneficial effects: the fasteners can play a role in fastening and connecting, and can realize the connection between different components. The connection part is fixed to the refrigerant radiator by the fasteners. At this time, the installation is convenient, the disassembly is easy, the practicality is strong, the structure is reliable, and it is easy to maintain and replace. In addition, the number of fins, spacing and other parameters can be adjusted according to specific needs, which is highly flexible.

[0015] According to some embodiments of the present invention, multiple heat dissipation parts are integrally formed on the connecting part.

[0016] The above technical solution has the following advantages or beneficial effects: multiple heat dissipation parts and connecting parts are integrally formed, so the fins are an integral structure, which is more stable and firm, and facilitates the installation and setting of the fins. At the same time, only one processing mold is needed to process and produce the fins, which facilitates the production and manufacturing of the fins. In addition, the integrally formed structural parts can better resist vibration and other mechanical stresses, and there is no need to carry out complicated assembly steps, which can reduce production costs and improve production efficiency.

[0017] According to some embodiments of the present invention, multiple heat dissipation parts are integrally formed on the connecting part.

[0018] The above technical solution has the following advantages or beneficial effects: multiple heat dissipation parts and connecting parts are integrally formed, so the fins are an integral structure, which is more stable and firm, and facilitates the installation and setting of the fins. At the same time, only one processing mold is needed to process and produce the fins, which facilitates the production and manufacturing of the fins. In addition, the integrally formed structural parts can better resist vibration and other mechanical stresses, and there is no need to carry out complicated assembly steps, which can reduce production costs and improve production efficiency.

[0019] According to some embodiments of this utility model, the thickness of the heat dissipation part is a, and the value range of a is: 1mm≤a≤2mm.

[0020] The above technical solution has the following advantages or beneficial effects: the thickness of the heat dissipation part cannot be too small, that is, less than 1mm. Such a thin heat dissipation part is prone to deformation or even breakage, especially when subjected to physical impact during cleaning or long-term exposure to vibration environment, its durability is poor. At the same time, the thickness of the heat dissipation part cannot be too large, that is, greater than 2mm. When manufacturing refrigerant radiators with the same surface area, using a thicker heat dissipation part requires more raw materials, which increases production costs.

[0021] According to some embodiments of this utility model, the distance between two adjacent heat dissipation parts is b, and the value of b is in the range of 2mm≤b≤5mm.

[0022] The above technical solution has the following advantages or beneficial effects: The distance between two adjacent heat dissipation parts cannot be too small, that is, less than 2mm. This will significantly increase the resistance encountered by the air when passing through the air duct, causing the fan to require higher power to maintain the same air volume, thereby increasing energy consumption and potentially generating greater noise. At the same time, the distance between two adjacent heat dissipation parts cannot be too large, that is, greater than 5mm. This will reduce the number of heat dissipation parts per unit volume, which will directly reduce the effective surface area of ​​the refrigerant heat sink, thereby reducing the overall heat exchange efficiency.

[0023] According to some embodiments of this utility model, the dimension of the fin in the height direction is c, the dimension of the fin in the width direction is d, and the dimension of the fin in the length direction is e. The value ranges of c, d, and e are respectively: 30mm≤c≤60mm, 30mm≤d≤80mm, and 40mm≤e≤100mm.

[0024] The above technical solution has the following advantages or beneficial effects: The fins have a reasonable height dimension, avoiding a reduction in the total heat exchange area per unit volume, thus preventing the need for more fins or a larger refrigerant radiator, which would increase the overall size and cost of the equipment. Simultaneously, it avoids the significant increase in air resistance that taller fins would cause when flowing through the heat exchanger, leading to higher fan power to maintain the same airflow, potentially causing noise problems, and reducing the overall system efficiency. The fins also have a reasonable width dimension, reducing the area available for heat exchange per unit length, thus reducing the refrigerant's heat exchange capacity, especially in low-wind-speed or high-temperature environments. The performance is worse at lower speeds. At the same time, to avoid increasing the contact area between the fins and the airflow, which would significantly increase the airflow resistance, the fan would need more power to push the air through the refrigerant radiator, resulting in increased energy consumption and noise. The dimensions of the fins in the length direction are reasonable. This would reduce the effective area that can participate in heat exchange, directly affecting the overall heat dissipation capacity. Under high load conditions, this may lead to problems such as compressor overheating and decreased system efficiency. At the same time, the longer the path that the air needs to overcome, the greater the wind resistance. Increased wind resistance would require the fan to have higher power to maintain the same airflow, thus increasing energy consumption and noise.

[0025] According to some embodiments of the present invention, the housing includes: a mounting base on which the refrigerant radiator and the fan are disposed; and a cover on which the cover is disposed, and a sealed space is formed between the cover and the mounting base.

[0026] The above technical solution has the following advantages or beneficial effects: the mounting base and the cover are components of the housing. The mounting base mainly serves as a mounting surface and can be used to install other components. The mounting base can provide certain support for the refrigerant radiator and fan, facilitating the installation and setting of the refrigerant radiator and fan. The cover serves as a cover, enabling the housing to form a closed state. The cover is placed on the mounting base, and a sealed space is constructed between the cover and the mounting base. The cover and the mounting base are fitted together, thereby enabling the housing to form a closed state.

[0027] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0038] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0039] The following is for reference. Figures 1-6 Outdoor unit 1 according to an embodiment of the present utility model is described.

[0040] The outdoor unit is part of the air conditioner's structure. The specific structure of the air conditioner will be described in detail below.

[0041] An air conditioner consists of an indoor unit and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and indoor heat exchanger, connected in sequence, form a refrigerant circuit. The refrigerant circulates in this circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve either the air conditioner's cooling or heating mode.

[0042] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0043] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0044] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0045] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet and expel the outdoor air, after it has been heated by the outdoor heat exchanger, through the outdoor air outlet. The outdoor fan provides power for the flow of outdoor air.

[0046] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening degree is adjustable to control the refrigerant flow rate and pressure.

[0047] The four-way valve is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform cooling mode or heating mode.

[0048] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate. In the heating mode of the air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0049] In some embodiments, the indoor heat exchanger further includes heat exchange fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0050] The indoor fan is configured to draw indoor air into the indoor unit through the third air inlet and discharge the indoor air, after heat exchange with the indoor heat exchanger, through the fourth air outlet. The indoor fan provides power for the airflow.

[0051] The air conditioner also includes a control unit, which is mainly used to control the compressor's operating frequency, the expansion valve's opening degree, the outdoor fan's speed, and the indoor fan's speed. The control unit is connected to the compressor, expansion valve, outdoor fan, and indoor fan via data cables to transmit communication information.

[0052] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device. The non-transitory computer-readable storage medium may include magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), card, stick, or keyboard drive).

[0053] The outdoor unit 1 according to an embodiment of the present invention may include a casing, a compressor, and an outdoor heat exchanger. The casing serves a protective function, protecting the internal components. The compressor compresses the low-temperature, low-pressure refrigerant gas from the indoor unit into a high-temperature, high-pressure gas, increasing the pressure and temperature of the refrigerant so that it can release heat in the external environment. The outdoor heat exchanger cools the high-temperature, high-pressure refrigerant gas and converts it into a liquid or gas-liquid mixture.

[0054] The compressor is housed inside the casing, and the outdoor heat exchanger is also housed inside the casing and connected to the compressor. By placing both the compressor and the outdoor heat exchanger inside the casing, the casing can protect them. The outdoor heat exchanger is connected to the compressor, and together they form a complete refrigeration cycle. The refrigerant circulates within this closed system, transferring heat from indoors to outdoors, improving energy efficiency and ensuring effective system operation.

[0055] like Figures 1-4As shown, the outdoor unit 1 may include an electronic control component 10, which is located inside the housing. The electronic control component 10 includes a housing 100 and a circuit board 101. The circuit board 101 is located inside the housing 100 and is electrically connected to the compressor. The circuit board 101 is also provided with an electronic control element 102. The electronic control component 10 can monitor, control, and regulate the operating status of the system, ensuring that the equipment can work efficiently and safely. The electronic control component 10 can be installed inside the housing. The housing 100 and the circuit board 101 are components of the electronic control component 10. The housing 100 can provide protection and improve the working environment of the internal components, reducing the frequency of failures caused by factors such as excessive temperature, dust, and moisture. The circuit board 101 can not only carry the electronic control element 102, but also realize the electrical connection and signal transmission between them. The circuit board 101 is installed inside the housing 100, at which time the housing 100 can protect the circuit board 101. The circuit board 101 is electrically connected to the compressor. The circuit board 101 and the compressor can be electrically connected through wires or terminals. In this way, the circuit board 101 can control the compressor's start-up, shutdown, speed, frequency, and other operating parameters. The electronic control element 102 is installed on the circuit board 101. At this time, the electronic control component 10 can realize intelligent control of the entire system.

[0056] like Figures 2-4 As shown, the electronic control component 10 may include a refrigerant radiator 103, which is at least partially disposed within the housing 100 and connected to the outdoor heat exchanger. The refrigerant radiator 103 can further cool the high-temperature, high-pressure refrigerant discharged from the compressor or flowing from the outdoor heat exchanger. Since the refrigerant radiator 103 is at least partially disposed within the housing 100, the housing 100 can provide some protection for the refrigerant radiator 103, reducing the frequency of malfunctions caused by factors such as excessive temperature, dust, and moisture. The connection of the refrigerant radiator 103 to the outdoor heat exchanger allows it to further reduce the refrigerant temperature, increase subcooling, and help improve the system's cooling capacity.

[0057] like Figures 2-4 As shown, the electronic control component 10 may include fins 104, which are disposed within the housing 100 and connected to the refrigerant radiator 103. The fins 104 can increase the heat exchange area, improve heat transfer efficiency, guide airflow direction, enhance convective heat transfer, prevent dust accumulation, and improve corrosion resistance. The housing 100 protects the fins 104. By connecting the fins 104 to the refrigerant radiator 103, the fins 104 increase the heat dissipation area of ​​the refrigerant radiator 103, improving heat exchange efficiency and enabling rapid heat dissipation.

[0058] like Figures 2-4As shown, the electronic control component 10 also includes a fan 105, which is disposed within the housing 100. The fan 105 can generate a low-temperature airflow inside the housing 100, making the temperature distribution inside the housing 100 more uniform. The housing 100 also protects the fan 105, reducing the frequency of malfunctions caused by factors such as excessive temperature, dust, and moisture.

[0059] like Figures 2-4 As shown, the fins 104 form an air duct 106, and the fan 105 is arranged opposite to the air duct 106. The air duct 106 can enhance the convective heat transfer efficiency between the air and the fins 104, reduce the air stagnation area, and improve the overall heat dissipation capacity. The fan 105 can be arranged opposite to the air duct 106 to improve the overall heat dissipation capacity. For example, the fins 104 can be placed vertically on the refrigerant radiator 103, and the fan 105 can be placed above or below the refrigerant radiator 103 to achieve the opposite arrangement of the fan 105 and the air duct 106. In addition, the fins 104 can also be placed horizontally on the refrigerant radiator 103, and the fan 105 can be placed on the right side. By arranging the fan 105 opposite to the air duct 106, the fan 105 can be arranged to circulate air, so that a low-temperature airflow is formed inside the housing 100.

[0060] like Figures 2-4 As shown, when the cooling capacity of the refrigerant radiator 103 is transferred to the fins 104, the fan 105 operates. After the airflow passes through the air duct 106, it forms a low-temperature airflow inside the housing 100 and convects with the hot air to cool the electronic control component 102. When the refrigerant radiator 103 transfers cooling capacity to the fins 104, the fan 105 circulates around it, forming a low-temperature airflow inside the housing 100. This makes the temperature distribution inside the housing 100 more uniform. Through the convection of hot and cold air, heat can be evenly distributed throughout the entire housing 100, making the temperature environment of each electronic control component 102 relatively consistent. This can greatly improve the working environment of the electronic control component 102, which is conducive to improving the overall performance and stability of the equipment, reducing maintenance frequency and downtime, thereby increasing production efficiency and reducing operating costs.

[0061] In this way, by adopting a fully sealed housing 100, adding fins 104 to the surface of the refrigerant radiator 103, and using a fan 105 to circulate the air, a low-temperature airflow is formed inside the sealed housing 100, and hot and cold air convection is carried out. This greatly improves the working environment of the electronic control components 102, making the temperature environment of each electronic control component 102 relatively uniform. At the same time, it can reduce the probability of failure caused by factors such as excessive temperature, dust, and moisture, significantly improve the reliability of the equipment, reduce the number of maintenance and downtime, thereby improving production efficiency and reducing operating costs.

[0062] In some specific embodiments of this utility model, such as Figures 4-6 As shown, the fins 104 include a heat dissipation section 107, and there are multiple heat dissipation sections 107. The heat dissipation section 107 can dissipate heat and improve heat transfer efficiency. Multiple heat dissipation sections 107 can be set to further increase the heat exchange area and improve heat transfer efficiency, so that heat can be dissipated more quickly. The multiple heat dissipation sections 107 are arranged at intervals to avoid interference between them and to make the distribution range of the multiple heat dissipation sections 107 wider. To a certain extent, this can increase the heat dissipation area of ​​the refrigerant radiator 103, improve heat exchange efficiency, and dissipate heat quickly.

[0063] In some specific embodiments of this utility model, such as Figures 4-6 As shown, multiple heat dissipation sections 107 are spaced apart in a vertical first direction, forming an air duct 106 between adjacent heat dissipation sections 107. A fan 105 is located on one side of the fins 104 in a vertical second direction. The vertical first direction and the vertical second direction are perpendicular to each other, allowing the fan 105 to be positioned opposite the air duct 106. In the vertical first direction, the multiple heat dissipation sections 107 are spaced apart. In the vertical second direction, the fan 105 is positioned on one side of the fins 104. The vertical first direction and the vertical second direction are perpendicular to each other, allowing the fan 105 to be positioned opposite the air duct 106. Specifically, the fins 104 can be placed vertically on the refrigerant radiator 103, in which case the fan 105 can be placed above or below the refrigerant radiator 103. Alternatively, the fins 104 can be placed horizontally on the refrigerant radiator 103, in which case the fan 105 can be placed on the right side, achieving airflow around the fins. When the refrigerant radiator 103 transfers cooling energy to the fins 104, the fan 105 circulates the air, creating a low-temperature airflow inside the housing 100. This makes the temperature distribution inside the housing 100 more uniform. Through the convection of hot and cold air, heat can be evenly distributed throughout the entire housing 100, making the temperature environment of each electronic control component 102 relatively consistent. This greatly improves the working environment of the electronic control component 102, which is beneficial to improving the overall performance and stability of the equipment, reducing maintenance frequency and downtime, thereby increasing production efficiency and reducing operating costs.

[0064] In some specific embodiments of this utility model, such as Figures 4-6As shown, the fins 104 also include a connecting portion 108. One side of the connecting portion 108 is connected to the refrigerant radiator 103, and multiple heat dissipation portions 107 are connected to the side of the connecting portion 108 away from the refrigerant radiator 103. The connecting portion 108 serves a connecting function, enabling the fins 104 to connect with other components. With one side of the connecting portion 108 connected to the refrigerant radiator 103, the fins 104 can increase the heat dissipation area of ​​the refrigerant radiator 103, improving heat exchange efficiency and allowing heat to dissipate quickly. The multiple heat dissipation portions 107 connected to the side of the connecting portion 108 away from the refrigerant radiator 103 further increase the heat dissipation area of ​​the refrigerant radiator 103, improving its heat exchange efficiency and allowing heat to dissipate quickly.

[0065] In some specific embodiments of this utility model, such as Figure 4 As shown, the connecting part 108 is integrally formed on the refrigerant radiator 103. That is, the connecting part 108 enables the fins 104 to be integrally formed on the refrigerant radiator 103. At this time, there is no additional joint interface between the fins 104 and the refrigerant radiator 103, which can reduce contact thermal resistance and allow heat to be transferred from the refrigerant to the air more efficiently. Secondly, the integrally formed design is generally more robust and durable than the assembled design, and can better resist vibration and other mechanical stresses. At the same time, the integral forming eliminates the need for complex assembly steps, which can reduce production costs and improve production efficiency. In addition, since no additional connectors or welding points are required, potential leakage points can be reduced, improving the system's sealing and reliability. Therefore, integrally forming the fins 104 on the refrigerant radiator 103 can improve heat exchange efficiency, enhance structural strength, and simplify the production process.

[0066] In some specific embodiments of this utility model, the electrical control component 10 further includes fasteners, and the connecting part 108 is fixed to the refrigerant radiator 103 by the fasteners. The fasteners provide a secure connection, enabling connections between different components. Since the connecting part 108 is fixed to the refrigerant radiator 103 by the fasteners, the fins 104 can also be fixedly connected to the refrigerant radiator 103 by the fasteners. This facilitates installation, disassembly, and practicality, ensuring a reliable structure. It also allows for easy maintenance and replacement. If the fins 104 are damaged, they can be replaced individually without replacing the entire component. Furthermore, it allows for the use of materials different from those used in the refrigerant radiator 103 piping to manufacture the fins 104, optimizing cost or performance. Additionally, the number, spacing, and other parameters of the multiple heat dissipation parts 107 can be adjusted according to specific needs, offering high flexibility. Therefore, the fasteners, such as screws, allow for more flexible design and maintenance.

[0067] In some specific embodiments of this utility model, such as Figures 4-6 As shown, multiple heat dissipation parts 107 are integrally formed on the connecting part 108. Since the multiple heat dissipation parts 107 and the connecting part 108 are integrally formed, the fins 104 are a single-piece structure, resulting in a more stable and robust structure. This facilitates the installation and setting of the fins 104. Furthermore, only one processing mold is needed to manufacture the fins 104, simplifying their production. Additionally, the integrally formed structure better resists vibration and other mechanical stresses, and eliminates the need for complex assembly steps, thus reducing production costs and improving production efficiency.

[0068] In some specific embodiments of this utility model, such as Figure 5 As shown, the thickness of the heat dissipation part 107 is 'a', and the value of 'a' ranges from 1mm to 2mm. It should be noted that the thickness 'a' of the heat dissipation part 107 needs to meet certain requirements. Specifically, the thickness of the heat dissipation part 107 cannot be too small, i.e., less than 1mm. If the heat dissipation part 107 is too thin, it is prone to deformation or even breakage, especially when subjected to physical impact during cleaning or long-term exposure to vibration environments, resulting in poor durability. Furthermore, if the heat dissipation part 107 is too thin, the actual contact area between it and the refrigerant radiator 103 pipe may be insufficient, leading to increased contact thermal resistance and hindering effective heat transfer. Secondly, an excessively thin heat dissipation part 107 is more prone to quality problems during manufacturing, such as warping or incomplete cutting, which places higher demands on the production process. Additionally, while a thinner heat dissipation part 107 helps improve airflow and heat transfer efficiency, it may also... This makes it easier for dust to adhere to its surface and difficult to remove. Long-term accumulation will affect heat dissipation performance. At the same time, the thickness of the heat dissipation part 107 cannot be too large, that is, greater than 2mm. When manufacturing a refrigerant radiator 103 with the same surface area, using a thicker heat dissipation part 107 requires more raw materials, which increases the weight of the entire refrigerant radiator 103 and also increases production costs. Secondly, using a thicker heat dissipation part 107 will increase the internal thermal resistance of the fins 104, thereby reducing the overall heat exchange efficiency. In addition, a thicker heat dissipation part 107 may obstruct airflow and reduce the effective ventilation area through the air duct 106, thereby reducing the heat exchange effect. Therefore, in order to better improve the heat exchange efficiency and dissipate heat quickly, the thickness a of the heat dissipation part 107 should be set to 1mm to 2mm.

[0069] In some specific embodiments of this utility model, such as Figure 5As shown, the distance between two adjacent heat dissipation parts 107 is b, and the value of b ranges from 2mm to 5mm. It should be noted that the distance b between two adjacent heat dissipation parts 107 needs to meet certain requirements. Specifically, the distance between two adjacent heat dissipation parts 107 cannot be too small, that is, less than 2mm. This would significantly increase the resistance encountered by airflow through the air duct 106, causing the fan 105 to require higher power to maintain the same airflow, thus increasing energy consumption and potentially generating more noise. Secondly, a smaller spacing between the heat dissipation parts 107 makes it easier for dust and other particles in the air to accumulate on their surface, forming a heat insulation layer, severely affecting heat exchange efficiency and potentially leading to localized overheating. Furthermore, a denser arrangement of the heat dissipation parts 107 places higher demands on the manufacturing process, especially in ensuring the flatness and consistency of the heat dissipation parts 107. Any slight deviation can lead to a decrease in heat exchange efficiency or physical damage. At the same time, the distance between two adjacent heat dissipation parts 107 cannot be... If the distance between two adjacent heat dissipation sections is too large, exceeding 5mm, it will reduce the number of heat dissipation sections 107 per unit volume, directly resulting in a decrease in the effective surface area of ​​the refrigerant radiator 103, thereby reducing the overall heat exchange efficiency. Secondly, an appropriate distance between the heat dissipation sections 107 can promote turbulent airflow between the heat dissipation sections 107, enhancing the heat exchange between the air and the surface of the heat dissipation section 107. When the distance between two adjacent heat dissipation sections 107 is too large, the airflow tends to be laminar, reducing the heat exchange efficiency. In addition, to achieve the same heat exchange capacity, a larger refrigerant radiator 103 size is required to compensate for the reduction in effective heat exchange area caused by the increased distance between the heat dissipation sections 107. This not only increases costs but may also limit the choice of installation space. Therefore, in order to better improve heat exchange efficiency and quickly dissipate heat, the distance b between two adjacent heat dissipation sections 107 should be set to 2mm to 5mm.

[0070] In some specific embodiments of this utility model, such as Figure 5 and Figure 6As shown, the dimension of fin 104 in the height direction is c, the dimension of fin 104 in the width direction is d, and the dimension of fin 104 in the length direction is e. The value ranges of c, d and e are: 30mm≤c≤60mm, 30mm≤d≤80mm, and 40mm≤e≤100mm, respectively. It should be noted that the dimension c of the fin 104 in the height direction needs to meet certain requirements. Specifically, the dimension c of the fin 104 in the height direction cannot be too small, i.e., less than 30mm. This would reduce the total heat exchange area per unit volume. This means that to achieve the same heat exchange capacity, more fins 104 or a larger refrigerant radiator 103 would be needed, increasing the overall size and cost of the equipment. Secondly, if the dimension c of the fin 104 in the height direction is too small, it may not provide enough space for the refrigerant to fully release or absorb heat, especially at high speeds where the refrigerant's transit time is short, limiting the heat exchange effect. Additionally, it may make it easier for dust and other contaminants to adhere to its surface. Due to the limited cleaning space, cleaning becomes more difficult, which will affect the performance and lifespan of the equipment in the long run. Furthermore, the dimension c of the fin 104 in the height direction cannot be too small... Larger fins (greater than 60mm) significantly increase air resistance as the heat exchanger flows through it. This not only requires the fan 105 to have higher power to maintain the same airflow but may also cause noise problems and reduce the overall system efficiency. Furthermore, excessively tall fins 104 can lead to uneven internal airflow distribution, particularly creating a large temperature difference between the connection 108 and the heat dissipation section 107, resulting in uneven heat transfer and reducing the actual heat transfer effect. Additionally, taller fins 104 are more fragile and easily deformed or damaged by external forces, affecting the normal operation of the refrigerant radiator 103. Moreover, they require more complex processes and technologies, leading to higher production costs. Therefore, to better improve heat exchange efficiency and quickly dissipate heat, the height dimension c of the fins 104 should be set between 30mm and 60mm.

[0071] The dimension d of the fins 104 in the width direction needs to meet a certain range. Specifically, the dimension of the fins 104 in the width direction cannot be too small, that is, less than 30mm. This would reduce the area available for heat exchange per unit length, reducing the heat exchange capacity of the refrigerant, especially in low wind speed or high temperature environments. Secondly, fins 104 that are too narrow are prone to deformation, bending, or even breakage, especially under external impact, resulting in poor mechanical stability. At the same time, fins 104 that are too narrow may reduce the connection area between them and the refrigerant radiator 103, affecting the fixing effect, and may also cause the fins 104 to fall off or become misaligned during assembly. In addition, if the fins 104 themselves are narrow, in order to ensure sufficient heat exchange area, the number of fins 104 must be increased, which may lead to the fins 104 being too closely spaced, causing dust accumulation problems. At the same time, the fins 104 in the width direction... The dimensional dimension in the axial direction cannot be too large, i.e., greater than 80mm. This would increase the contact area with the airflow, thereby significantly increasing the airflow resistance. This would require the fan 105 to have greater power to push the air through the refrigerant radiator 103, resulting in increased energy consumption and noise. Secondly, wide fins 104 may cause uneven airflow distribution, especially in the edge areas where "dead corners" or vortices may appear, reducing the overall heat exchange efficiency. At the same time, due to the restricted airflow, heat is difficult to be carried away in time, which may form a "heat retention zone" and affect the heat transfer efficiency. In addition, wider fins 104 require more material and have higher requirements for stamping, forming and other processes, increasing manufacturing costs and equipment weight. Therefore, in order to better improve heat exchange efficiency and quickly dissipate heat, the dimensional dimension d of the fins 104 in the width direction should be set to 30mm to 80mm.

[0072] The length dimension 'e' of fin 104 needs to meet certain requirements. Specifically, the length dimension of fin 104 cannot be too small, i.e., less than 40mm. This would reduce the effective area available for heat exchange, directly affecting the overall heat dissipation capacity. Under high load conditions, this could lead to compressor overheating and decreased system efficiency. Secondly, short fins 104 may cause heat to concentrate in certain areas, resulting in excessively high local temperatures, which could lead to material fatigue and accelerated aging. Furthermore, if a single fin 104 is too short, the number of fins 104 must be increased to achieve a sufficient total heat exchange area. This could lead to a smaller fin spacing, resulting in dust accumulation and increased air resistance. Additionally, excessively short fins 104 may result in an unstable connection between them and the refrigerant radiator 103, potentially leading to loosening or detachment during long-term operation. Conversely, the length dimension of fin 104 cannot be too large, i.e., greater than 1... The longer the airflow path, the greater the wind resistance. Increased wind resistance requires the fan 105 to maintain the same airflow, thus increasing energy consumption and noise. Secondly, if the airflow is close to saturation temperature after passing the first fin 104, the heat exchange effect of the subsequent fins 104 will decrease significantly, forming an "ineffective heat exchange zone," which reduces the heat exchange efficiency per unit area. At the same time, excessively long fins 104 are prone to bending, deformation, or even breakage due to their own weight or vibration, especially in high temperature or high humidity environments. In addition, longer fins 104 are more difficult to keep flat during stamping and assembly, and are more likely to be damaged during transportation or installation. Moreover, excessively long fins 104 may occupy more space, limiting the compact design of the equipment. Therefore, in order to better improve heat exchange efficiency and quickly dissipate heat, the length dimension e of the fins 104 should be set to 40mm to 100mm.

The mounting base 109 and the cover 110 are components of the housing 100. The mounting base 109 primarily serves a mounting function and can be used to install other components. Both the refrigerant radiator 103 and the fan 105 can be disposed on the mounting base 109. In this case, the mounting base 109 provides some support for the refrigerant radiator 103 and the fan 105, facilitating their installation and placement. This allows the refrigerant radiator 103 and the fan 105 to be at least partially disposed within the housing 100. The cover 110 serves a covering function. This allows the housing 100 to be in a closed state. The cover 110 is placed on the mounting base 109, and a sealed space is formed between the cover 110 and the mounting base 109. The cover 110 and the mounting base 109 are fitted together, thereby making the housing 100 in a closed state. At this time, the housing 100 can play a protective role, improve the working environment of the electronic control component 102, reduce the frequency of failures caused by factors such as excessive temperature, dust and moisture, significantly improve the reliability of the equipment, reduce the number of maintenance and downtime, thereby improving production efficiency and reducing operating costs.
