Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] An embodiment of the present invention provides a battery heat dissipation module 100 .

[0022] See also Figures 1 to 8 In one embodiment of the present invention, the battery heat dissipation module 100 includes an outer shell 110, and the outer shell 110 is formed with a plurality of battery compartments 110a, a plurality of heat conduction compartments 110b, and a plurality of heat exhaust compartments 110c; The battery compartment 110a and the heat transfer compartment 110b are arranged alternately; the heat exhaust compartment 110c is disposed at one end of the battery compartment 110a and the heat transfer compartment 110b, and the battery compartment 110a, the heat transfer compartment 110b and the heat exhaust compartment 110c are interconnected; The battery compartment 110a is used to install the rechargeable battery 120; The battery heat dissipation module 100 further includes a refrigeration system 130 and a tubular heat exchanger 133. The refrigeration system 130 includes a cooling plate 131 and a circulation pump 132. The circulation pump 132 is used to provide power for the flow of the refrigerant in the cooling plate 131. The cooling plate 131 is installed in the heat transfer chamber 110b and is attached to the rechargeable battery 120. The tubular heat exchanger 133 is installed in the heat exhaust chamber 110c to absorb heat.

[0023] It can be understood that the technical solution of the present invention helps to efficiently export the heat generated by the rechargeable battery 120 during operation by arranging the battery compartment 110a and the heat conduction compartment 110b alternately, avoids the accumulation of heat in the battery compartment 110a, and improves the heat dissipation efficiency of the battery; and the cooling plate 131 is close to the rechargeable battery 120, which can directly absorb and conduct the heat generated by the rechargeable battery 120, so that the heat is quickly transferred to the cooling plate 131. The circulating pump 132 drives the refrigerant to flow in the cooling plate 131, thereby continuously taking away the heat generated by the battery. Thereby avoiding the technical problems of battery performance degradation and shortened life due to overheating. Further, by arranging a tubular heat exchanger 133 in the battery heat dissipation module 100, the tubular heat exchanger 133 is installed in the heat exhaust compartment 110c to absorb the residual heat conducted from the battery compartment 110a, thereby realizing the temperature control in the battery compartment 110a, thereby reducing the heat accumulation in the battery compartment 110a and further improving the heat dissipation effect.

[0024] In a specific embodiment, the battery heat dissipation module 100 also includes a heat dissipation fan 140, which is disposed in the heat exhaust bin 110c and is located on a side of the tubular heat exchanger 133 away from the battery bin 110a. The heat dissipation fan 140 is used to drive the heat of the battery bin 110a to flow to the surface of the tubular heat exchanger 133.

[0025] Specifically, the addition of the heat dissipation fan 140 enhances the fluidity of heat, improves the heat dissipation efficiency, and further ensures that the temperature of the battery is maintained within a safe range during operation.

[0026] It should also be understood that when the tubular heat exchanger 133 absorbs heat, overheating and damage of the cooling fan 140 is avoided, thereby increasing the service life of the cooling fan 140.

[0027] See also Figure 5 , in a preferred embodiment, the refrigeration system 130 further includes a radiator 134 and a first solenoid valve 135 - 1 ; The circulation pump 132, the radiator 134, and the cooling plate 131 are circulated and connected in sequence; The tubular heat exchanger 133 and the first solenoid valve 135 - 1 are in communication; The tubular heat exchanger 133 is communicated with the output end of the cooling plate 131 , and the first solenoid valve 135 - 1 is communicated with the input end of the cooling plate 131 .

[0028] It is understandable that when the tubular heat exchanger 133 and the cooling plate 131 both rely on the radiator 134 and the circulating pump 132 for cooling, the heat dissipation efficiency is improved while reducing energy consumption. Furthermore, the tubular heat exchanger 133 and the cooling plate 131 are both used for heat absorption cooling, which improves the gas conversion efficiency of the refrigerant and avoids the refrigerant entering the circulating pump 132 carrying too much liquid refrigerant, thereby damaging the circulating pump 132.

[0029] Specifically, in practical applications, the cooling plate 131 is mainly used to absorb heat from the rechargeable battery 120. The tubular heat exchanger 133 is mainly used to absorb moisture in the charging compartment, so that the air moisture in the tubular heat exchanger 133 condenses into larger water droplets and is discharged through the cooling fan 140.

[0030] When the heat generation of the rechargeable battery 120 is low, the cooling plate 131 is closed and the first solenoid valve 135 - 1 is controlled so that the tubular heat exchanger 133 has a cooling effect, thereby achieving humidity regulation of the charging bin in the heat exhaust bin 110c, further improving the service life of the rechargeable battery 120.

[0031] See also Figure 7 , in another preferred embodiment of the present invention, the refrigeration system 130 further includes a radiator 134 and a second solenoid valve 135 - 2 ; The circulation pump 132, the radiator 134, the cooling plate 131 and the tubular heat exchanger 133 are circulated and connected in sequence; The second solenoid valve 135 - 2 is connected to the output end and the input end of the tubular heat exchanger 133 and is used to control the refrigerant flow of the tubular heat exchanger 133 .

[0032] It is understandable that in this solution, the cooling plate 131 and the tubular heat exchanger 133 can achieve cooling at the same time, and the setting of the tubular heat exchanger 133 can be used to share the conversion efficiency of the refrigerant in the cooling plate 131, so that the refrigerant in the cooling plate 131 is a gas-liquid mixed state, thereby improving the cooling uniformity of the cooling plate 131 and avoiding local overheating of the battery. Furthermore, while achieving cooling, the tubular heat exchanger 133 converts the liquid refrigerant in the gas-liquid mixed state into a gaseous refrigerant, thereby reducing the risk of damage and maintenance of the circulating pump 132.

[0033] See also Figure 8 In one embodiment, the refrigeration system 130 includes a radiator 134; the circulation pump 132, the radiator 134, and the cooling plate 131 are circulated and connected in sequence; The tubular heat exchanger 133 performs heat exchange through a water cooling system 150 .

[0034] It is understandable that the tubular heat exchanger 133 and the cooling plate 131 are respectively arranged in the refrigeration system 130 and the water cooling system 150, so that the tubular heat exchanger 133 and the cooling plate 131 are independently controlled by the two systems. Specifically, the two systems do not interfere with each other, which is convenient for maintenance and control.

[0035] When the heat of the rechargeable battery 120 is high, the refrigeration system 130 is activated to cool down and remove heat; when the heat generated by the rechargeable battery 120 is low, the cooling fan 140 and the water cooling system 150 are used to cool down and remove heat. Specifically, the tubular heat exchanger 133 absorbs heat, which can avoid the operating environment temperature of the cooling fan 140, and reduce the environmental humidity of the battery compartment 110a, thereby increasing the service life of the rechargeable battery 120.

[0036] See also Figures 1 to 5 In a specific embodiment, the first surface shell 111 of the outer shell 110 is further formed with a mesh area 111a; The first surface shell 111 is a surface shell in the arrangement direction of the battery compartment 110a and the heat conduction compartment 110b; The battery heat dissipation module 100 further includes a moisture absorbent 160 , which is attached to the inner side of the first surface shell 111 and is arranged corresponding to the mesh area 111 a . The mesh area 111 a is used for natural evaporation of moisture in the moisture absorbent 160 .

[0037] It is understandable that if Figure 1As shown, the first surface shell 111 is usually arranged above the battery heat dissipation module 100 away from the ground. Specifically, the moisture absorbent 160 is arranged in the mesh area 111a to help the moisture absorbent 160 to effectively absorb moisture and dissipate heat, thereby preventing the accumulation of moisture and heat in the battery compartment 110a and further optimizing the heat dissipation effect.

[0038] In a specific embodiment, Figure 1 and Figure 2 As shown, the moisture absorbent member 160 is further provided with a connecting portion 161 and an avoiding portion 162; The connecting portion 161 is sequentially connected to the cooling plates 131 that are spaced apart from each other, and the avoiding portion 162 is used to avoid the rechargeable battery 120 so that a gap exists between the moisture absorbing member 160 and the rechargeable battery 120 .

[0039] It is understandable that the connection between the connection portion 161 and the cooling plate 131 further fixes the moisture absorbent member 160 . The connection portion 161 and the cooling plate 131 also cool the moisture absorbent member 160 , thereby helping to improve the moisture absorption effect of the moisture absorbent member 160 .

[0040] Specifically, the arrangement of the avoidance portion 162 allows a gap to exist between the moisture absorbent member 160 and the rechargeable battery 120 , thereby improving the natural ventilation effect of the moisture absorbent member 160 and facilitating the evaporation of moisture in the moisture absorbent member 160 .

[0041] Furthermore, in order to enable the moisture absorbent member 160 to be cyclically used for a long time, the moisture absorbent member 160 is made of silica gel.

[0042] See also Figure 1 In a specific embodiment, the outer shell 110 is further provided with a second surface shell 112, and the second surface shell 112 is provided on one side of the cooling fan 140 for installing the cooling fan 140, and the second surface shell 112 is detachably connected to the outer shell 110.

[0043] Specifically, the provision of the second surface shell 112 facilitates the installation and maintenance of the cooling fan 140 , while ensuring that the cooling fan 140 is reliably fixed, thereby improving the overall stability and working efficiency of the battery cooling module 100 .

[0044] Optionally, the rechargeable battery 120 , the cooling plate 131 , and the tubular heat exchanger 133 can be installed by disassembling the second surface shell 112 .

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
