[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1-4 As shown, a durable, cold- and heat-resistant automotive battery includes a casing assembly 1. Heat exchange tubes are evenly distributed inside the upper part of the casing assembly 1, and both ends of the heat exchange tubes are connected to an insulation connecting pipe 3. A heating mechanism 4, a delivery pump 5, and a cooling mechanism 6 are installed in the middle of the insulation connecting pipe 3. The delivery pump 5 drives the coolant to circulate between the heating mechanism 4, the cooling mechanism 6, and the heat exchange tubes. When heat dissipation of the battery is required, the semiconductor cooling chip 603 and the fan 606 are energized. The fins 605 and the fan 606 improve the heat dissipation effect of the heating surface of the semiconductor cooling chip 603, thereby improving the cooling effect of the cooling surface of the semiconductor cooling chip 603. This allows the coolant to be dissipated through the fins 602, and further cools the battery through the heat exchange tubes. When the ambient temperature is low, the heating wire 403 heats the heat-conducting plate 402, thereby quickly heating the coolant inside the heating box 401, increasing the battery temperature, and thus meeting the usage requirements in extreme temperature environments.
[0021] Cooling mechanism 6 includes a cooling box 601, fin one 602, a thermoelectric cooler 603, a heat insulation plate 604, fin two 605, a fan 606, and a protective cover 607. The lower part of the cooling box 601 is fixedly connected to the upper right side of the wall shell assembly 1. The lower part of fin one 602 penetrates the top wall shell of the cooling box 601 and is fixedly connected to the inner bottom wall of the cooling box 601. The lower part of the protective cover 607 is fixedly connected to the upper part of the cooling box 601. The outer periphery of the heat insulation plate 604 is fixedly connected to the lower middle part of the protective cover 607. The outer periphery of the thermoelectric cooler 603 is fixedly connected to the middle part of the heat insulation plate 604. The lower part of fin 603 is fixedly connected to the upper part of fin one 602 by thermally conductive silicone grease. The lower part of fin two 605 is fixedly connected to the upper part of the thermoelectric cooler 603 by thermally conductive silicone grease. Fan 606 is installed on the upper part of fin two 605. Fin one 602 divides the interior of the cooling box 601 into multiple channels. The thermoelectric cooler 603 heats on the upper side and cools on the lower side. The heat dissipation effect of the heating surface of the thermoelectric cooler 603 is improved by fin two 605 and fan 606, thereby improving the cooling effect of the cooling surface of the thermoelectric cooler 603. Thus, the coolant is dissipated through fin one 602.
[0022] The heating mechanism 4 includes a heating box 401, heat-conducting plates 402, heating wires 403, and a heat-insulating cover 404. The bottom of the heating box 401 is fixedly connected to the top left side of the wall shell assembly 1. The lower ends of multiple heat-conducting plates 402 penetrate through the top wall shell of the heating box 401 and are fixedly connected to the inner bottom wall of the heating box 401. The lower part of the heat-insulating cover 404 is fixedly connected to the upper part of the heating box 401. The heating wires 403 are evenly distributed on the upper part of the multiple heat-conducting plates 402. The multiple heat-conducting plates 402 are distributed inside the heating box 401, and the left and right ends of the heat-conducting plates 402 do not contact the inner walls of the left and right sides of the heating box 401. Therefore, the heat-conducting plates 402 divide the heating box 401 into multiple channels. The coolant flows in the multiple channels and heats the heat-conducting plates 402 through the heating wires 403, thereby quickly heating the coolant inside the heating box 401.
[0023] The wall shell assembly 1 includes an outer shell 101, an inner liner 102, and a sandwich 104. The sandwich 104 is disposed between the outer shell 101 and the inner liner 102. The outer shell 101 and the inner liner 102 are connected by multiple connecting posts. The heat exchange tubes are evenly distributed inside the sandwich 104. The sandwich 104 is filled with a heat-conducting medium. The sandwich 104 is only disposed on the four side walls and bottom of the wall shell assembly 1. The top wall shell does not have a sandwich 104. The heat-conducting medium allows the heat exchange tubes to better exchange heat with the battery, improving the heat exchange effect and efficiency. Furthermore, integrating the heat exchange tubes directly into the wall shell assembly 1 reduces the need for additional piping, lowers the risk of electrolyte leakage due to piping connections, and saves space inside the battery pack.
[0024] An insulation layer 103 is fixedly connected to the inner wall of the outer casing 101 to prevent the outer casing 101 from transferring the ambient temperature to the heat exchange tube, thus ensuring the heat dissipation effect and efficiency of the heat exchange tube for the battery.
[0025] The outer periphery of the outer casing 101 is provided with shock-absorbing pads made of rubber, which can reduce the vibration of the battery during vehicle operation and protect the battery.
[0026] The upper part of the wall housing assembly 1 is provided with a handle 2, which facilitates the handling and use of the battery.
[0027] Working principle:
[0028] The drive pump 5 causes the coolant to circulate between the heating mechanism 4, the cooling mechanism 6, and the heat exchange tubes. When the battery needs to be cooled, the thermoelectric cooler 603 and the fan 606 are energized. The fins 605 and the fan 606 improve the heat dissipation effect of the heating surface of the thermoelectric cooler 603, thereby improving the cooling effect of the cooling surface of the thermoelectric cooler 603. The coolant is then cooled by the fins 602, and the battery is cooled by the heat exchange tubes. When the ambient temperature is low, the heating wire 403 heats the heat-conducting plate 402, thereby quickly heating the coolant inside the heating box 401, thereby increasing the battery temperature and meeting the needs of use in extreme temperature environments.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
