DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] See also Figure 1-4The present application provides a technical solution: an adaptive battery heat dissipation management device, comprising a battery holder seat 1, wherein a storage compartment 2 is provided at the upper end of the battery holder seat 1, wherein the storage compartment 2 is divided into a temperature control compartment 21 and a battery placement compartment 22, and the temperature control compartment 21 and the battery placement compartment 22 are provided in a one-to-one correspondence.

[0018] The battery holder 1 is the base of the entire structure, supporting and fixing all components to ensure that the battery pack is firmly installed to prevent damage caused by vibration or movement.

[0019] The storage compartment 2 is a comprehensive storage space, which includes two functional areas: a temperature control compartment 21 and a battery placement compartment 22, aiming to achieve effective organization and temperature control management of batteries.

[0020] The temperature control compartment 21 is equipped with a circulating cooling group 3 of the cooling system to adjust and maintain the temperature of the battery working environment within a suitable range. Through heat exchange with the external environment, it can prevent the battery from performance degradation or safety risks caused by overheating.

[0021] The battery placement compartment 22 is directly used to accommodate battery cells, and is closely adjacent to or works in conjunction with the temperature control compartment 21 to ensure that each battery can obtain the necessary cooling effect, maintain the overall performance of the battery pack and extend its service life.

[0022] A circulating cooling group 3 is arranged in the temperature control chamber 21, and the input end of the circulating cooling group 3 is connected to the output end of the coolant storage tank 5 arranged on the battery pack cover plate 4 at the upper end of the battery holder seat 1. The output end of the circulating cooling group 3 is divided into three, one way is connected to the input end of the coolant pipe group support plate 6 arranged between the battery placement chambers 22, and the other way is connected to the bottom cooling group 7 at the lower end of the battery placement chamber 22. A coolant recovery group 8 is arranged at the lower end of the battery holder seat 1, and the third way is connected to the output end of the coolant recovery group 8.

[0023] The circulating cooling group 3 is located in the temperature control chamber 21 and is the core of the entire cooling system. It absorbs the heat generated by the battery when it is working by sucking in the coolant and circulating it, and then transfers the heat to achieve continuous cooling of the battery pack.

[0024] The coolant storage tank 5 is used to store coolant and serve as a cold source for the circulating cooling group 3. When the coolant is output through the circulating cooling group 3, it absorbs the heat saved by the battery and then returns to the coolant recovery group 8, forming a closed circulation system to ensure the continuous supply of coolant.

[0025] The coolant pipe group support plate 6 is located between the battery placement compartments 22, and is connected to the circulating cooling group 3 to form a distributed cooling network, so that the coolant can flow around the sides of the battery, evenly taking away the heat and avoiding local overheating.

[0026] The bottom cooling group 7 performs enhanced cooling for the high temperature that may accumulate at the bottom of the battery, because the bottom of the battery is usually where the heat accumulates most severely, which effectively improves the heat dissipation efficiency.

[0027] The coolant recovery group 8 is responsible for collecting the coolant after heat dissipation, which may include functions such as filtering and removing impurities to ensure that the circulating coolant always maintains good heat exchange performance, and then transports it to the input end of the circulating cooling group again to complete the entire circulation process.

[0028] Furthermore, a temperature sensor 9 is provided on the inner wall of the battery placement compartment 22 , and an output end of the temperature sensor 9 is connected to an external controller, and an output end of the external controller is connected to an output end of the circulating cooling group 3 .

[0029] The temperature sensor 9 is installed on the inner wall of the battery compartment 22, close to the battery pack. It can monitor the temperature changes in the area in real time and accurately, and promptly capture any signs of overheating that may cause battery performance degradation or safety risks. The output end of the temperature sensor 9 is connected to the external controller. Once a temperature abnormality is detected, the information will be immediately conveyed to the controller. The controller will then respond and send instructions to the circulating cooling group 3 through its output end to adjust the output of the cooling system, increase the circulation rate of the coolant or change the flow direction, so as to quickly and effectively respond to local or overall temperature increases.

[0030] Furthermore, solenoid valves are provided on the pipelines between the circulating cooling group 3 and the coolant pipe group support plate 6 , the bottom cooling group 7 , and the coolant recovery group 8 .

[0031] As an electronically controlled valve, the solenoid valve can accurately control the flow direction and flow rate of the coolant in different branch pipes according to the instructions of the external controller. According to the actual temperature requirements of the battery, the flow ratio of the coolant in the battery storage compartment 22, the bottom cooling group 7 and the return coolant recovery group 8 can be flexibly adjusted to achieve efficient and accurate temperature management.

[0032] Furthermore, heat dissipation holes 10 are provided on the side walls of the battery compartment 22 .

[0033] The heat dissipation holes 10 allow external air to enter the battery compartment 22, and after contacting the battery surface, carry away part of the heat and discharge it to the external environment by natural convection.

[0034] Inside the battery pack, batteries in different locations may have temperature differences due to working conditions or layout reasons. Side wall heat dissipation holes can help eliminate these tiny temperature differences, promote thermal balance inside the battery pack, reduce the risk of local overheating, and improve the stability and consistency of the entire battery system.

[0035] Furthermore, a reinforcing rib plate 11 is provided on the outer side of the battery placement compartment 22 .

[0036] When in use: open the filling port of the coolant storage tank 5, add coolant to the appropriate level according to the recommended specifications and types, then close and check for leaks, place the battery cells smoothly into the battery compartment 22 according to the design layout, pay attention to the gaps between the batteries, ensure that the coolant pipe group support plate 6 and the bottom cooling group 7 can effectively contact the battery surface to achieve the best heat dissipation effect, connect the external controller and perform initialization settings, and preset the temperature threshold and cooling strategy according to the characteristics of the battery pack and the expected working conditions. During use, regularly check the temperature sensor 9 data of the battery compartment 22, monitor the temperature changes of the battery pack, ensure that the system automatically adjusts the cooling intensity as needed, and observe the airflow inside and outside the heat dissipation hole 10 to ensure smooth natural convection. Check the coolant quality regularly and replace or purify it through the coolant recovery group 8 when necessary to maintain efficient operation of the system. If the temperature sensor 9 detects abnormally high temperature, immediately adjust the working mode of the circulating cooling group 3 through the external controller to enhance the cooling effect. When the battery temperature drops to the preset temperature, the solenoid valves located on the coolant pipe group support plate 6 and the bottom cooling group 7 pipeline are closed, and the solenoid valve on the coolant recovery group 8 is opened to realize the recovery of the coolant.

[0037] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
