[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figure 1-6 The present invention provides a technical solution: an aluminum shell assembly for fire prevention and heat dissipation of an automotive power battery, including a housing mechanism 1 and a closing mechanism 2 assembled on the top of the housing mechanism 1. The housing mechanism 1 includes a battery housing 101 and two groups of partition boards 103. A plurality of heat absorption plates 106 are fixedly installed inside the battery housing 101. Heat dissipation grooves 107 are opened at the tops of the heat absorption plates 106. A water cooling pipe 4 is fixedly installed between the heat absorption plates 106. Two groups of assembly grooves 102 are opened on the inner wall of the battery housing 101. Assembly plates 104 slidably installed inside the assembly grooves 102 are fixedly installed at both ends of the two groups of partition boards 103. Mounting seats 3 are fixedly installed at the lower parts of the front and back of the battery housing 101. Assembly holes 108 are provided around the top of the battery housing 101. The closing mechanism 2 includes a closing cover 201. A plurality of blowers 203 are fixedly installed on one side of the top of the closing cover 201 through an air inlet seat 202. A plurality of exhaust fans 205 are fixedly installed on the other side of the top of the closing cover 201 through an exhaust seat 205. Flanges 206 are fixedly installed at the tops of the blowers 203 and the exhaust fans 204.
[0022] Based on the above structure settings, the fireproof and heat-dissipating aluminum shell assembly for automotive power batteries is composed of a housing mechanism 1 and a closing mechanism 2. Among them, the housing mechanism 1 is a storage mechanism for vehicle battery modules. With the help of the housing mechanism 1, heat dissipation and cooling treatment can be carried out on the bottom of the battery module in a water-cooled manner. The closing mechanism 2 can be a closing and sealing mechanism for the aluminum shell assembly. With the help of the closing mechanism 2, heat dissipation and cooling treatment can be carried out on the top of the vehicle battery module in an air-cooled manner. Specifically, during the working process, the battery housing 101 can store the vehicle's battery modules. The heat absorption plate 106 can absorb the heat generated by the battery modules during operation. The heat dissipation grooves 107 facilitate the dissipation of the heat at the bottom of the battery modules. The water-cooling pipes 4 are installed between the heat absorption plates 106, so that the heat of the heat absorption plates 106 and the bottom of the battery modules can be absorbed and cooled through the water-cooling pipes 4, realizing the function of the assembly to dissipate heat from the battery modules in a water-cooled manner. The assembly plates 104 at both ends of the partition plate 103 are slidably installed in the assembly grooves 102, so that the partition plate 103 can be used to isolate and insulate between the battery groups, avoiding interference between the battery groups. The mounting seat 3 can fixedly install the battery housing 101 at the bottom of the vehicle. The closing cover 201 can be installed on the top of the battery housing 101 through the cooperation of bolts and the assembly holes 108, so that the closing cover 201 can close and protect the battery modules inside the battery housing 101. On one side of the top of the closing cover 201, a plurality of hair dryers 203 are fixedly installed through the air inlet seat 202. The hair dryers 203 can blow air on the battery groups inside the battery housing 101. And on the other side of the top of the closing cover 201, an exhaust fan 204 is installed through the exhaust seat 205. The exhaust fan 204 can extract and discharge the heat generated by the battery modules during operation inside the battery housing 101. Thus, through the hair dryers 203 and the exhaust fan 204, heat dissipation and cooling treatment can be carried out on the top of the battery modules inside the battery housing 101 in an air-cooled manner, realizing heat dissipation and cooling treatment of the bottom and top of the battery modules in the assembly in two ways. The two heat dissipation methods improve the heat dissipation quality and efficiency during the long-term use of the battery modules, avoiding the situation that the vehicle's battery modules accelerate aging or even catch fire and explode due to poor heat dissipation, and improving the stability during the long-term use of the battery modules. The flange 206 facilitates the connection of the hair dryers 203 and the exhaust fan 204 to the external air pipes.
[0023] Furthermore, one end of the water-cooling pipe 4 is fixedly installed with a water inlet joint 401 that penetrates the battery housing 101, and the other end of the water-cooling pipe 4 is fixedly installed with a water outlet joint 402 that penetrates the battery housing 101. Among them, the water inlet joint 401 can be connected to the cooling water tank built in the vehicle, so as to facilitate the cooling coolant in the water tank to enter the interior of the water-cooling pipe 4. The water outlet joint 402 is connected to the cooling water tank built in the vehicle, and the used coolant can be cooled by the cooling water tank, so that the coolant can perform a circulating cooling process on the battery assembly.
[0024] Furthermore, both sides of the bottom of the closing cover 201 are threadedly installed with a plurality of mounting rings 5 that cooperate with the hair dryer 203 and the exhaust fan 204. Filter covers 501 are fixedly installed inside the mounting rings 5. Among them, the mounting rings 5 can install the filter covers 501, and the filter covers 501 can filter the air flow entering the interior of the battery housing 101 and the discharged heat, avoiding the situation that impurities in the cooling gas enter the battery housing 101 and cause pollution to the battery assembly.
[0025] Furthermore, a plurality of anti-scraping plates 109 are fixedly installed at the bottom of the battery housing 101. Among them, the anti-scraping plates 109 can perform anti-scraping treatment on the bottom of the battery housing 101, avoiding or reducing the situation that the battery housing 101 is deformed and damaged when being hung.
[0026] Furthermore, a plurality of mounting holes 301 are provided on the two mounting seats 3, and a plurality of positioning grooves 302 are formed at the top of the mounting seats 3. Among them, the mounting holes 301 can install and fix the mounting seats 3 to the bottom of the vehicle through bolts, and the positioning grooves 302 can be connected to the limit clamping plates at the bottom of the vehicle, thus ensuring the accuracy of the mounting seats 3 when installed on the bottom of the vehicle.
[0027] Furthermore, heat insulation pads 105 are fixedly installed on the outer walls of the two partition plates 103. Among them, the heat insulation pads 105 improve the heat insulation performance between the partition plates 103, so that the partition plates 103 can perform heat insulation treatment on the battery groups.
