It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there can be a component disposed therebetween.

[0049] The technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.

[0050] The battery heat dissipation module 100 is provided.

[0051] Please refer to Figures 1 to 8 In an embodiment of the present application, the battery heat dissipation module 100 comprises an outer housing 110, which is formed with a plurality of battery compartments 110a, a plurality of heat conduction compartments 110b and a plurality of heat dissipation compartments 110c;

[0052] The battery compartments 110a and the heat conduction compartments 110b are arranged alternately; the heat dissipation compartments 110c are arranged at one end of the battery compartments 110a and the heat conduction compartments 110b, and the battery compartments 110a, the heat conduction compartments 110b and the heat dissipation compartments 110c are communicated with each other;

[0053] The battery compartments 110a are used for mounting rechargeable batteries 120;

[0054] The battery heat dissipation module 100 further comprises a refrigeration system 130 and a tubular heat exchanger 133; the refrigeration system 130 comprises a cooling plate 131 and a circulating pump 132, which is used for providing power for the flow of refrigerant in the cooling plate 131; the cooling plate 131 is mounted on the heat conduction compartments 110b and is attached to the rechargeable batteries 120;

[0055] The tubular heat exchanger 133 is mounted on the heat dissipation compartments 110c and is used for absorbing heat.

[0056] It can be understood that, by arranging the battery compartments 110a and the heat conduction compartments 110b alternately, the present application helps to efficiently dissipate the heat generated by the rechargeable batteries 120 during operation, avoids the accumulation of heat in the battery compartments 110a and improves the heat dissipation efficiency of the batteries; and the cooling plate 131 is attached to the rechargeable batteries 120 and can directly absorb and conduct the heat generated by the rechargeable batteries 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 removing the heat generated by the batteries. Thus, the technical problem of performance degradation and short service life of the batteries caused by overheating is avoided. Further, by arranging the tubular heat exchanger 133 in the battery heat dissipation module 100 and mounting the tubular heat exchanger 133 in the heat dissipation compartments 110c, the residual heat conducted from the battery compartments 110a is absorbed, thereby realizing temperature control in the battery compartments 110a and reducing the accumulation of heat in the battery compartments 110a, further improving the heat dissipation effect.

[0057] In a specific embodiment, the battery heat dissipation module 100 further comprises a heat dissipation fan 140, which is arranged in the heat dissipation compartment 110c and located on the side of the tubular heat exchanger 133 away from the battery compartment 110a. The heat dissipation fan 140 is used to drive the heat of the battery compartment 110a to flow to the surface of the tubular heat exchanger 133.

[0058] Specifically, the addition of the heat dissipation fan 140 enhances the flow of heat and improves the heat dissipation efficiency, further ensuring that the temperature of the battery remains within a safe range during operation.

[0059] It should also be understood that in the case of heat absorption by the tubular heat exchanger 133, the heat dissipation fan 140 is prevented from overheating and damage, improving the service life of the heat dissipation fan 140.

[0060] Please refer to Figure 5 In a preferred embodiment, the refrigeration system 130 further comprises a heat sink 134 and a first electromagnetic valve 135-1.

[0061] The circulation pump 132, the heat sink 134, and the cooling plate 131 are sequentially and circularly connected.

[0062] The tubular heat exchanger 133 and the first electromagnetic valve 135-1 are connected.

[0063] The tubular heat exchanger 133 is connected to the output end of the cooling plate 131, and the first electromagnetic valve 135-1 is connected to the input end of the cooling plate 131.

[0064] It can be understood that when the tubular heat exchanger 133 and the cooling plate 131 rely on the heat sink 134 and the circulation pump 132 for refrigeration, the heat dissipation efficiency is improved while the energy consumption is reduced. Further, the tubular heat exchanger 133 and the cooling plate 131 are both used for heat absorption refrigeration, which improves the gaseous conversion efficiency of the refrigerant and avoids the damage of the circulation pump 132 caused by the refrigerant carrying too much liquid refrigerant.

[0065] Specifically, in actual application, the cooling plate 131 is mainly used for heat absorption of the charging battery 120. The tubular heat exchanger 133 is mainly used for absorbing 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 heat dissipation fan 140.

[0066] When the heat production of the charging battery 120 is low, the cooling plate 131 is closed, and the first electromagnetic valve 135-1 is controlled to make the tube heat exchanger 133 have a refrigeration effect, so as to realize humidity regulation of the charging battery in the heat exhaust bin 110c, and further improve the service life of the charging battery 120.

[0067] Referring to Figure 7 In another preferred embodiment of the present application, the refrigeration system 130 further comprises a radiator 134 and a second electromagnetic valve 135-2.

[0068] The circulating pump 132, the radiator 134, the cooling plate 131 and the tube heat exchanger 133 are sequentially and circularly connected.

[0069] The second electromagnetic valve 135-2 is connected to the output end and the input end of the tube heat exchanger 133, and is used for controlling the refrigerant flow of the tube heat exchanger 133.

[0070] It can be understood that in the present scheme, the cooling plate 131 and the tube heat exchanger 133 can realize refrigeration at the same time, and the tube 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 in a gas-liquid mixed state, thereby improving the refrigeration uniformity of the cooling plate 131 and avoiding local overheating of the battery. Further, the tube heat exchanger 133 realizes the conversion of liquid refrigerant in the gas-liquid mixed state to gaseous refrigerant while realizing refrigeration, thereby reducing the risk of damage and maintenance of the circulating pump 132.

[0071] Referring to Figure 8 In an embodiment, the refrigeration system 130 comprises a radiator 134; the circulating pump 132, the radiator 134, and the cooling plate 131 are sequentially and circularly connected.

[0072] The tube heat exchanger 133 exchanges heat through a water cooling system 150.

[0073] It can be understood that the tube heat exchanger 133 and the cooling plate 131 are respectively arranged in the refrigeration system 130 and the water cooling system 150, and the tube heat exchanger 133 and the cooling plate 131 are independently controlled through the two systems. Specifically, the two systems do not interfere with each other, which is convenient for maintenance and control.

[0074] When the heat of the charging battery 120 is high, the refrigeration system 130 is enabled to cool and remove heat; when the heat generation of the charging battery 120 is low, the heat dissipation fan 140 and the water cooling system 150 are used to cool and remove heat. Specifically, the tube heat exchanger 133 absorbs heat, which can avoid the operating environment temperature of the heat dissipation fan 140 and reduce the environmental humidity of the battery compartment 110a, thereby improving the service life of the charging battery 120.

[0075] Please refer to Figures 1 to 5 In a specific embodiment, the first face shell 111 of the outer shell 110 is further formed with a mesh area 111a;

[0076] The first face shell 111 is a surface shell of the arrangement direction of the battery compartment 110a and the heat conduction compartment 110b;

[0077] The battery heat dissipation module 100 further comprises a moisture absorbing member 160, which is attached to the inner side of the first face shell 111 and is arranged corresponding to the mesh area 111a, and the mesh area 111a is used for the natural evaporation of moisture of the moisture absorbing member 160.

[0078] It can be understood that, as Figure 1 The first face shell 111 is usually arranged above the ground away from the battery heat dissipation module 100, and specifically, the arrangement of the moisture absorbing member 160 in the mesh area 111a helps the moisture absorbing member 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.

[0079] In a specific embodiment, as Figure 1 And Figure 2 The moisture absorbing member 160 is further provided with a connecting portion 161 and a avoiding portion 162;

[0080] The connecting portion 161 is sequentially connected with the spaced cooling plates 131, and the avoiding portion 162 is used to avoid the charging battery 120, so that the moisture absorbing member 160 has a gap with the charging battery 120.

[0081] It can be understood that the connection of the connecting portion 161 and the cooling plate 131 realizes the further fixation of the moisture absorbing member 160. And the connecting portion 161 and the cooling plate 131 realize the cooling of the moisture absorbing member 160, thereby helping to improve the moisture absorbing effect of the moisture absorbing member 160.

[0082] Specifically, the arrangement of the avoiding portion 162 makes the moisture absorbing member 160 have a gap with the charging battery 120, which improves the natural ventilation effect of the moisture absorbing member 160 and helps the moisture evaporation of the moisture absorbing member 160.

[0083] Further, in order to enable long-term recycling of the moisture absorbing member 160, the moisture absorbing member 160 is made of silica gel.

[0084] Please refer to Figure 1 In specific embodiments, the outer shell 110 is further provided with a second face shell 112, which is arranged on one side of the heat dissipation fan 140 and used for mounting the heat dissipation fan 140. The second face shell 112 is detachably connected with the outer shell 110.

[0085] Specifically, the arrangement of the second face shell 112 facilitates the mounting and maintenance of the heat dissipation fan 140, while ensuring reliable fixation of the heat dissipation fan 140 and improving the overall stability and working efficiency of the battery heat dissipation module 100.

[0086] Optionally, the rechargeable battery 120, the cooling plate 131 and the tubular heat exchanger 133 can be mounted by detaching the second face shell 112.

[0087] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features. Such modifications or replacements do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
