Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a high-efficiency battery cooling structure. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes, forming a cup, tank, or other container or composite container that generates an electric current. It has a positive and a negative electrode. With technological advancements, the term "battery" now generally refers to any small device capable of generating electrical energy, such as a solar cell. The main performance parameters of a battery include electromotive force, capacity, specific energy, and resistance. Using batteries as an energy source provides a stable voltage, stable current, long-term stable power supply, and minimal susceptibility to external influences. Batteries are simple in structure, portable, easy to charge and discharge, unaffected by external climate and temperature, and offer stable and reliable performance, playing a significant role in various aspects of modern life.

[0003] In the existing technology, electric vehicles and hybrid vehicles use electric motors as the power source for vehicle operation, and battery packs are installed on the vehicle to power the electric motors.

[0004] However, the following problems were found in the implementation of the relevant technology: most of the existing battery heat has only one cooling function, cooling the bottom or top, and the cooling function is relatively simple. It cannot completely wrap the battery on both sides for cooling, resulting in inefficient battery cooling, which reduces the heat dissipation efficiency and lifespan of the battery. Therefore, a high-efficiency battery cooling structure is proposed. Utility Model Content

[0005] This invention proposes a high-efficiency battery cooling structure, which solves the problem in related technologies where most batteries only have one cooling function, such as bottom or top cooling, resulting in limited cooling functionality and the inability to completely wrap and cool both sides of the battery, leading to inefficient battery cooling.

[0048] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0049] Example 1

[0050] Please see Figure 1 - Figure 5 A high-efficiency battery cooling structure includes: a lower cooling box 100 and an upper cooling box 200, the upper cooling box 200 being located above the lower cooling box 100; two sets of lower copper shells 101 fixedly extending through the top of the lower cooling box 100; two sets of copper plates 102 disposed on the inner bottom walls of the two sets of lower copper shells 101 and extending through the lower cooling box 100; multiple temperature sensors 300 fixedly installed inside the two sets of lower copper shells 101; two sets of upper copper shells 201 fixedly extending through the bottom of the upper cooling box 200; two sets of copper plates 202 disposed on the inner bottom walls of the two sets of upper copper shells 201 and extending through the upper cooling box 200; a water-cooling drive mechanism 400 disposed between the lower cooling box 100 and the upper cooling box 200; and a water-cooling heat dissipation mechanism 500 disposed on the top of the upper cooling box 200.

[0051] The water-cooling heat dissipation mechanism 500 includes a fixed frame 501, which is fixedly installed on the top of the water-cooling heat dissipation mechanism 500; an exchange box 502, which is installed through the fixed frame 501; two sets of copper plates 503, which are respectively installed through the upper and lower sides of the exchange box 502; the water-cooling heat dissipation mechanism 500 also includes two support frames 504, which are respectively fixedly installed on the upper and lower sides of the exchange box 502; and multiple fans 505, which are respectively fixedly installed on the two support frames 504. The multiple fans 505 are electrically connected to multiple temperature sensors 300 through a controller.

[0052] This utility model provides a high-efficiency battery cooling structure. When the temperature sensor 300 detects that the battery temperature exceeds the set standard, the fan 505 is activated. The fan 505 blows out the heat absorbed by the copper sheet 503 to offset the heat, thereby cooling the water entering the exchange box 502.

[0053] By aligning the lower cooling box 100 and the upper cooling box 200 vertically, the lower copper shell 101 and the upper copper shell 201 form a sealed chamber for placing the battery. Water flows inside both the lower cooling box 100 and the upper cooling box 200, and the water contacts the copper sheet 102 and the copper sheet 202 to offset the heat dissipated from the battery by the copper sheet 102 and the copper sheet 202, so that both sides of the battery can be cooled.

[0054] Furthermore, the water-cooling drive mechanism 400 includes a water pump 401, which is fixedly installed on the top of the upper cooling box 200 and is electrically connected to multiple temperature sensors 300 via a controller; a drain pipe 402, which is fixedly connected to the output end of the water pump 401 and extends into the interior of the exchange box 502 at one end away from the water pump 401; a drain pipe 403, which is fixedly connected to the input end of the water pump 401 and extends into the interior of the lower cooling box 100 at one end away from the water pump 401; a water inlet pipe 405, which is fixedly installed through the other end of the exchange box 502 and extends into the interior of the upper cooling box 200; and a water supply pipe 404, which is fixedly installed through the other side of the upper cooling box 200 and extends into the interior of the lower cooling box 100 at the other end.

[0055] Specifically, when the temperature sensor 300 detects that the battery temperature exceeds the set standard, the water pump 401 is started. The water pump 401 draws water from the lower cooling box 100. The drawn water is transported to the heat exchange box 502 through the second drain pipe 403 and the first drain pipe 402 for cooling. The cooled water is then transported to the upper cooling box 200 through the water inlet pipe 405 and to the lower cooling box 100 through the water delivery pipe 404. The water pump 401 draws water from the lower cooling box 100 to achieve the purpose of circulating water cooling for the battery.

The connecting mechanism 600 includes: two sets of mounting ears 1 601, which are fixedly installed on both sides of the lower cold box 100 respectively; two sets of mounting ears 2 602, which are fixedly installed on both sides of the upper cold box 200 respectively; a long bolt 603, which is inserted between the mounting ears 1 601 and the mounting ears 2 602; and a nut 604, which is threadedly connected to the long bolt 603.
