Description

Technical Field

[0002] Energy storage temperature control products are products used to manage and control the temperature of energy storage devices such as batteries and supercapacitors. During the use of energy storage devices, heat is generated due to the chemical reaction inside the battery or supercapacitor. If the temperature is too high, it will not only affect the performance and life of the energy storage device, but may also cause safety accidents. Therefore, energy storage temperature control products monitor the temperature of energy storage devices and automatically control them according to the set temperature range to ensure the safe, stable and efficient operation of energy storage devices. Energy storage temperature control products are widely used in electric vehicles, solar energy storage systems, wind power generation and other fields.

[0003] The overall layout of existing energy storage temperature control equipment is usually as follows: the compressor is located in the upper cavity of the unit, at the return air close to the condenser. The higher return air speed near the compressor will cause the working capacity of the fluorine system to decrease; in addition, the compressor is heavy and located in the upper cavity of the unit, resulting in a higher center of gravity for the unit, which may cause the unit to shake or even tip over during transportation.

DETAILED DESCRIPTION

[0030] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0031] like Figure 1-Figure 6 As shown, an embodiment of the present application provides an energy storage temperature control device, including a casing 1, a compressor 2, a heat exchanger 3 and a heat exchange fan 4. Among them, the casing 1 is provided with an installation cavity 11 located at the lower part and a heat exchange cavity 12 located at the upper part, the cavity wall of the installation cavity 11 is provided with a first return air port 111, the cavity wall of the heat exchange cavity 12 is provided with a second return air port 121 and an air outlet 122, and a ventilation hole 13 is provided between the installation cavity 11 and the heat exchange cavity 12; the compressor 2 is installed in the installation cavity 11; the heat exchanger 3 and the heat exchange fan 4 are both installed in the heat exchange cavity 12, the heat exchanger 3 divides the heat exchange cavity 12 into a first sub-heat exchange cavity 123 and a second sub-heat exchange cavity 124, the ventilation hole 13 and the second return air port 121 are both connected with the first sub-heat exchange cavity 123, the air outlet 122 is connected with the second sub-heat exchange cavity 124, and the heat exchange fan 4 is configured to drive the airflow to enter from the first return air port 111 and the second return air port 121 and flow through the heat exchanger 3 and then be discharged from the air outlet 122.

[0032] The energy storage temperature control device provided in the embodiment of the present application can be applied to the temperature control of energy storage equipment such as a generator room.

[0033] Specifically, the energy storage temperature control device provided in the embodiment of the present application installs the compressor 2 in the installation cavity 11, which is located at the lower part of the casing 1, and installs the heat exchanger 3 and the heat exchange fan 4 in the heat exchange cavity 12, which is located at the upper part of the casing 1. Generally, the compressor 2 is heavy, and the heat exchanger 3 and the heat exchange fan 4 are lighter than the compressor 2. In this way, the overall center of gravity of the energy storage temperature control device in the embodiment of the present application is low, so that the unit as a whole is more stable when the unit is running. The energy storage temperature control device provided in the embodiment of the present application has a low overall center of gravity and more stable operation, which avoids the situation in the prior art where the compressor is installed on the upper part of the unit, causing the overall unit to sway when it is running.

[0034] Furthermore, the heat exchange fan 4 of the present application can exhaust air from the air outlet 122 by operating, so that negative pressure is generated in the casing 1 to form return air, thereby forming a heat exchange and exhaust air cycle. If the compressor 2 is in the high-speed return air position of the heat exchange fan 4, the high-speed return air speed will reduce the working capacity of the fluorine system. The energy storage temperature control device provided in the embodiment of the present application is provided with a compressor 2 installed in the installation cavity 11, the heat exchanger 3 and the heat exchange fan 4 are both installed in the heat exchange cavity 12, and the cavity wall of the installation cavity 11 is provided with a first return air port 111, and the cavity wall of the heat exchange cavity 12 is provided with a second return air port 121 and an air outlet 122, and a ventilation hole 13 is provided between the installation cavity 11 and the heat exchange cavity 12, and the ventilation hole 13 and the second return air port 121 are both connected to the first sub-heat exchange cavity 123, and the air outlet 122 is connected to the second sub-heat exchange cavity 124. In this way, when the energy storage temperature control device is running, when the heat exchange fan 4 rotates, the return air entering from the first return air port 111 enters the first sub-heat exchange cavity 123 through the ventilation hole 13, and the return air entering from the second return air port 121 enters the first sub-heat exchange cavity 123, the return air of the first sub-heat exchange cavity 123 is heat exchanged through the heat exchanger 3, and the airflow after heat exchange enters the second sub-heat exchange cavity 124 and is discharged from the air outlet 122.

[0035] Since the compressor 2 and the heat exchange fan 4 are located in the installation chamber 11 and the heat exchange chamber 12 respectively, the compressor 2 is far away from the heat exchange fan 4. Therefore, the return air entering the installation chamber 11 from the first return air port 111 has a lower wind speed at the position of the compressor 2, and the return air entering from the second return air port 121 does not flow through the compressor 2, so that the return air of the heat exchange fan 4 has less impact on the operation of the compressor 2, avoiding the high return air speed near the compressor 2 causing the fluorine system to reduce its working capacity. Since part of the return air flows through the compressor 2, the compressor 2 can be cooled to avoid the compressor 2 temperature being too high to affect its normal operation.

[0036] In an exemplary embodiment, Figure 1-Figure 6 As shown, the housing 1 includes a first side wall 14, a second side wall 15, a third side wall 16 and a fourth side wall 17 which are connected in sequence in an annular shape, the first side wall 14 is provided with an air outlet 122, and at least one of the second side wall 15, the third side wall 16 and the fourth side wall 17 is provided with a second return air outlet 121. Among them, the first side wall 14, the second side wall 15, the third side wall 16 and the fourth side wall 17 can be surrounded by a rectangular frame, the first side wall 14 can be the front side wall of the housing 1, the second side wall 15, the third side wall 16 and the fourth side wall 17 can be the left side wall, the rear side wall and the right side wall of the housing 1 respectively, and the first side wall 14 and the third side wall 16 are arranged oppositely, and the second side wall 15 and the fourth side wall 17 are arranged oppositely. The first side wall 14, the second side wall 15, the third side wall 16 and the fourth side wall 17 can be used to enclose the heat exchange cavity 12 to form the cavity wall of the heat exchange cavity 12.

[0037] Specifically, in the energy storage temperature control device of the embodiment of the present application, the first side wall 14 provided with the air outlet 122 will not be installed against the wall, so that the unit can smoothly and quickly discharge air and dissipate heat, and at least one of the second side wall 15, the third side wall 16 and the fourth side wall 17 is provided with a second return air outlet 121, so that it can be compatible with the application scenario of single-sided return air from the second return air outlet 121 on one of the second side wall 15, the third side wall 16 and the fourth side wall 17. For example, during the actual installation of the casing 1 of the energy storage temperature control device, if one or both sides of the casing 1 need to be installed against the wall, the wall will block the second return air outlet 121 on the side wall of the casing 1 against the wall, so that the return air operation can be performed from the second return air outlet 121 on the side wall of the casing 1 that is not against the wall.

[0038] Therefore, the above structural setting can expand the application scenarios of the energy storage temperature control device of the present application and improve the scope of application of the energy storage temperature control device.

[0039] In an exemplary embodiment, Figure 5 As shown, the heat exchanger 3 is a U-shaped heat exchanger, the heat exchange fan 4 is arranged in the U-shaped heat exchanger, the opening of the U-shaped heat exchanger faces the first side wall 14, and the second side wall 15, the third side wall 16 and the fourth side wall 17 are all provided with a second return air port 121. The outer side of the U-shaped heat exchanger can form a first sub-heat exchange cavity 123, and the inner side of the U-shaped heat exchanger can form a second sub-heat exchange cavity 124. Figure 5 In the figure, the direction indicated by the arrow is the flow direction of the airflow, and the airflow can return from the left, right and rear sides and exhaust from the front side.

[0040] Specifically, compared with the I-shaped (straight) heat exchanger, L-shaped heat exchanger, and V-shaped heat exchanger, the U-shaped heat exchanger of the present application has a larger heat exchange area and good heat exchange capacity; and adapted to the U-shaped heat exchanger, a second return air port 121 is provided on the second side wall 15, the third side wall 16, and the fourth side wall 17, so that the U-shaped heat exchanger has high heat exchange efficiency and the energy storage temperature control device has high cooling and temperature control efficiency. The heat exchange fan 4 is arranged in the U-shaped heat exchanger, so that the airflow flowing in from the second return air port 121 of the second side wall 15, the third side wall 16, and the fourth side wall 17 can flow to the U-shaped heat exchanger from the side of the U-shaped heat exchanger away from the port, and after heat exchange with the U-shaped annular device, it flows into the U-shaped heat exchanger and is finally discharged from the air outlet 122.

[0041] In an exemplary embodiment, the U-shaped heat exchanger may be a tube-fin heat exchanger, which may be configured to include a plurality of fins so as to increase the heat exchange area of ​​the heat exchanger. Of course, the U-shaped heat exchanger may also be other types of heat exchangers.

[0042] In an exemplary embodiment, Figure 5As shown, a partition 5 is provided in the housing 1 for separating the installation cavity 11 and the heat exchange cavity 12 , and a ventilation hole 13 is provided in the partition 5 , and the ventilation hole 13 is located on the side of the U-shaped heat exchanger away from the first side wall 14 .

[0043] Specifically, a partition 5 is provided in the casing 1 to separate the installation cavity 11 and the heat exchange cavity 12. The partition 5 can be a transverse partition. The installation cavity 11 is formed on the lower side of the partition 5, and the heat exchange cavity 12 is formed on the upper side of the partition 5. The partition 5 can be used to support and fix the heat exchange fan 4 and the heat exchanger 3.

[0044] The ventilation hole 13 provided on the partition 5 is located on the side of the U-shaped heat exchanger away from the first side wall 14, for example, the ventilation hole 13 can be provided on the rear side of the partition 5 and located on the rear side of the U-shaped heat exchanger, so that the ventilation hole 13 is connected with the first sub-heat exchange cavity 123 outside the U-shaped heat exchanger. In this way, the wind flowing from the installation cavity 11 into the first sub-heat exchange cavity 123 through the ventilation hole 13 flows to the side of the U-shaped heat exchanger away from the U-shaped opening, and after sufficient heat exchange with the U-shaped heat exchanger, flows to the air outlet 122.

[0045] In an exemplary embodiment, Figure 5 As shown, the interval S between the U-shaped heat exchanger and the third side wall 16 is not less than 150 mm.

[0046] The interval S between the U-shaped heat exchanger and the third side wall 16 is set to be not less than 150 mm. If the interval S is too small, the air volume of the lower return air entering from the first return air port 111 through the ventilation hole 13 entering the first sub-heat exchange chamber 123 is affected, resulting in a large attenuation of the air volume of the lower return air, thereby affecting the heat exchange effect. Setting the interval S between the U-shaped heat exchanger and the third side wall 16 to be not less than 150 mm can ensure the air volume of the lower return air and ensure the heat exchange effect.

[0047] In order to ensure the return air volume from the second return air outlet 121 of the second side wall 15, the third side wall 16 and the fourth side wall 17, the distance between the second side wall 15 and the wall, the distance between the third side wall 16 and the wall, and the distance between the fourth side wall 17 and the wall can be set to no less than 150mm, such as: set to 150mm-200mm.

[0048] In an exemplary embodiment, Figure 5 As shown, there are gaps between the U-shaped heat exchanger and the second side wall 15 and between the U-shaped heat exchanger and the fourth side wall 17 to facilitate the installation of the U-shaped heat exchanger.

[0049] In an exemplary embodiment, Figure 2-Figure 4As shown, a plurality of the second side walls 15 , the third side walls 16 and the fourth side walls 17 are provided with second return air outlets 121 , and the casing 1 further comprises a baffle (not shown), which is detachably mounted to the casing 1 and can partially block the second return air outlets 121 .

[0050] Specifically, a second return air outlet 121 is provided on multiple side walls among the second side wall 15, the third side wall 16 and the fourth side wall 17, such as: a second return air outlet 121 is provided on two or three side walls among the second side wall 15, the third side wall 16 and the fourth side wall 17, so as to expand the ventilation cross-sectional area of ​​the second return air outlet 121, and improve the return air volume and the cooling and heat dissipation efficiency of the energy storage temperature control device of the present application. A baffle is provided to be detachably mounted to the casing 1, so that the operator can install the baffle on the side wall of the casing 1 close to the wall to block the second return air outlet 121 on the side wall close to the wall. In addition, by installing and removing the baffle, the return air volume of the energy storage temperature control device of the present application can be adjusted, so that the working parameters of the energy storage temperature control device of the present application are adjustable.

[0051] In an exemplary embodiment, Figure 1 As shown, there are multiple heat exchangers 3 and multiple heat exchange fans 4, and the multiple heat exchangers 3 are arranged in sequence along the up and down direction, and the multiple heat exchange fans 4 are arranged in sequence along the up and down direction, and the multiple heat exchangers 3 and the multiple heat exchange fans 4 correspond to each other one by one.

[0052] Specifically, multiple heat exchangers 3 and multiple heat exchange fans 4 are arranged in one-to-one correspondence, and multiple heat exchangers 3 and multiple heat exchange fans 4 are arranged in sequence along the up and down directions. This not only facilitates the transportation and assembly of the heat exchangers 3 and the heat exchange fans 4, but also improves the heat exchange efficiency of the energy storage temperature control equipment.

[0053] If the heat exchangers 3 are arranged adjacent to each other on the left and right, and the heat exchange fan 4 is arranged in the concave cavity of the heat exchanger 3, when the heat exchanger 3 is a U-shaped heat exchanger, the sides of the two adjacent U-shaped heat exchangers will fit together, reducing the overall heat exchange area of ​​the energy storage temperature control device, thereby affecting the heat exchange efficiency. If one U-shaped heat exchanger is used to correspond to two or more heat exchange fans 4, the size of the U-shaped heat exchanger is too large, and it is inconvenient to assemble and transport.

[0054] In an exemplary embodiment, Figure 5 As shown, there are multiple compressors 2, and the multiple compressors 2 are connected to the multiple heat exchangers 3 in a one-to-one correspondence to form multiple refrigerant circulation loops arranged in parallel. Among them, there can be two compressors 2, two heat exchangers 3 and two heat exchange fans 4, and two parallel refrigerant circulation loops can be formed. Of course, the compressors 2, the heat exchangers 3, the heat exchange fans 4 and the refrigerant circulation loops are not limited to two, and their number can be adjusted as needed.

[0055] Specifically, multiple groups of refrigerant circulation circuits are arranged in parallel, so that each group of refrigerant circulation circuits can work independently, and multiple groups of refrigerant circulation circuits arranged in parallel can also work together, so that the appropriate number of groups of refrigerant circulation circuits can be selected according to the different temperature control needs of the energy storage device, which expands the application scope of the energy storage temperature control device of the present application in the temperature control link of the energy storage device. In addition, if a refrigerant circulation circuit fails, other refrigerant circulation circuits are not affected and can still work normally.

[0056] In addition to the compressor 2 and the heat exchanger 3, the refrigerant circulation circuit may also include a reversing valve, a throttle valve, a second heat exchanger, etc. The energy storage temperature control device may also include a coolant circuit. The coolant in the coolant circuit can exchange heat with the refrigerant in the second heat exchanger, so as to cool the energy storage device by the coolant in the coolant circuit.

[0057] In an exemplary embodiment, the sizes of the plurality of heat exchangers 3 are set to be the same, and the sizes of the plurality of heat exchange fans 4 are set to be the same.

[0058] Specifically, the sizes of the multiple heat exchangers 3 are set to be substantially the same, and the sizes of the multiple heat exchange fans 4 are set to be substantially the same, so that the processing, manufacturing and assembly of the heat exchangers 3 and the heat exchange fans 4 are facilitated. By setting substantially the same multiple heat exchangers 3 and multiple heat exchange fans 4, the heat exchange parameters of each refrigerant circulation loop are also the same, and the cooling capacity is also substantially the same. Of course, the sizes of the multiple heat exchangers 3 can also be set to be different, and the sizes of the multiple heat exchange fans 4 can also be set to be different.

[0059] In an exemplary embodiment, Figure 6 As shown, the housing 1 includes a bottom wall 19, and the first return air port 111 is disposed on the bottom wall 19. The bottom wall 19 of the housing 1 can be formed on the cavity wall at the bottom side of the installation cavity 11, and the first return air port 111 disposed on the bottom wall 19 can realize the return air from the lower side of the housing 1.

[0060] Specifically, the first return air inlet 111 is arranged on the bottom wall 19, and a support structure is arranged at the bottom of the casing 1, so that there is a gap between the bottom wall 19 of the casing 1 and the installation ground, so that air can enter the installation cavity 11 from the first return air inlet 111, flow through the compressor 2, and then enter the heat exchange cavity 12.

[0061] Since the first return air inlet 111 is located at the bottom of the installation cavity 11, the first return air inlet 111 is far away from the heat exchange fan 4 located in the heat exchange cavity 12, and the first return air inlet 111 needs to pass through the ventilation hole 13 to enter the heat exchange cavity 12. Therefore, the wind speed at the position of the first return air inlet 111 and the position of the compressor 2 is relatively small, so the wind entering from the first return air inlet 111 and flowing through the compressor 2 will not affect the normal operation of the fluorine system.

[0062] The energy storage temperature control device of the embodiment of the present application can realize the return of air from the left side, right side, rear side and bottom side of the housing 1. Of course, the first return air port 111 can also be set on other cavity walls of the installation cavity 11 except the cavity wall on the bottom side, such as the cavity wall on the left, right and rear sides of the installation cavity 11.

[0063] In an exemplary embodiment, Figure 1 and Figure 5 As shown, the heat exchange fan 4 is an axial flow fan.

[0064] Specifically, in an axial flow fan, the gas enters the impeller axially, that is, the gas flows parallel to the axis of the axial flow fan. Axial flow fans are used in situations where the flow rate requirements are high and the pressure requirements are low. In the energy storage temperature control device of the embodiment of the present application, the axial flow fan extracts the air in the heat exchange chamber 12 and the installation chamber 11, so that the heat exchange chamber 12 and the installation chamber 11 generate negative pressure, driving the ambient air outside the unit to enter the casing 1 from the first return air port 111 and the second return air port 121. The return air flows through the heat exchanger 3 for heat exchange, and then gathers and accelerates to flow into the suction side of the heat exchange fan 4 with the lowest pressure, and finally is boosted by the heat exchange fan 4 and discharged outward at high speed through the exhaust chamber.

[0065] In an exemplary embodiment, Figure 1 and Figure 5 As shown, the heat exchange fan 4 includes an inner rotor motor 41 and fan blades 42 , and the fan blades 42 are detachably mounted on the output shaft of the inner rotor motor 41 .

[0066] Specifically, the heat exchange fan 4 of the embodiment of the present application has its blades 42 detachably mounted on the output shaft of the inner rotor motor 41, so that if the blades 42 or the inner rotor motor 41 are damaged, they can be removed and replaced with a universal electric screwdriver or wrench, which is convenient for maintenance. In addition, the heat exchange fan 4 of this structure has the advantage of low noise when the blades 42 rotate at high speed.

[0067] The heat exchange fans in the prior art are mostly fans with integrated motors and blades. When the motor is damaged, it is generally impossible to replace the motor and blades without the fan manufacturer's special removal tools. However, the heat exchange fan 4 of the embodiment of the present application has an inner rotor motor 41 and blades 42 that are easy to disassemble and assemble, and are convenient for maintenance and replacement.

[0068] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0069] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
