[0023] Please see Figs. 1-2 This utility model provides a technical solution: a lightweight composite energy-saving heat exchanger for new energy vehicles, comprising;

[0024] An integrated heat dissipation structure, comprising a double-layer heat exchange tube 100, heat exchange fins 200, a liquid collection tank A300, and a liquid collection tank B400;

[0025] The outer side of the double-layer heat exchange tube 100 is welded and fixed to the heat exchange fins 200, and there are multiple heat exchange fins 200. There is a gap between every two heat exchange fins 200, and a ventilation groove A201 is opened in the middle of the heat exchange fins 200.

[0026] The liquid collection tank A300 is located on one side of the heat exchange fin 200, and the liquid collection tank A300 is fixed to the heat exchange fin 200 by welding;

[0027] The liquid collection tank B400 is located on the other side of the heat exchange fin 200, and the liquid collection tank B400 is fixed to the heat exchange fin 200 by welding.

[0028] Furthermore, the double-layer heat exchange tube 100 is made of brass, while the heat exchange fins 200, liquid collection tank A300, and liquid collection tank B400 are all made of aluminum alloy. Copper has a high specific heat capacity, which can absorb and store a large amount of heat. At the same time, it has a fast heat dissipation rate, which can quickly dissipate heat to the surrounding environment. Aluminum alloy has a low density and is lightweight, which makes the radiator design lighter and helps to reduce the overall weight of the equipment. Aluminum alloy has high thermal conductivity, which can quickly transfer heat from the heat source to the fin surface and dissipate it through air convection.

[0029] Furthermore, the double-layer heat exchange tube 100 is composed of two copper tubes and is in an arc shape. The arc shape of the double-layer heat exchange tube 100 makes the pipe distribution more compact, and longer pipes can be arranged on the heat exchange fins 200. Therefore, the liquid is transported over a longer distance and the heat dissipation effect is better. The double-layer copper tube doubles the liquid heat exchange distance and the heat transfer time is longer, which greatly improves the heat exchange efficiency.

[0030] Furthermore, the liquid collection tank A300 is provided with multiple ventilation slots B301, with a gap between each pair of ventilation slots B301. The multiple ventilation slots B301 can prevent the obstruction of natural wind, and the rectangular liquid collection tank A300 allows the liquid inside the liquid collection tank A300 to exchange heat through the liquid collection tank A300, thereby improving the heat exchange efficiency of the liquid.

[0031] Furthermore, the liquid collection tank B400 is provided with multiple ventilation slots C401, with a gap between each pair of ventilation slots C401. The multiple ventilation slots C401 can prevent the obstruction of natural wind, and the rectangular liquid collection tank B400 allows the liquid inside the liquid collection tank B400 to exchange heat through the liquid collection tank B400, thereby improving the heat exchange efficiency of the liquid.

[0032] Furthermore, one end of the double-layer heat exchange tube 100 has an elbow A101, one end of which is connected to the liquid collection tank A300, and the other end of the double-layer heat exchange tube 100 has an elbow B102, one end of which is connected to the liquid collection tank B400. A connecting pipe A302 is provided on the outside of the liquid collection tank A300, and a connecting pipe B402 is provided on the outside of the liquid collection tank B400.

[0033] Working principle: Hotter coolant is transported to the inside of the collection tank A300 via connecting pipe A302. The rectangular collection tank A300 allows for heat exchange between the liquid inside and outside, improving heat exchange efficiency. Subsequently, elbow A101 transports the coolant from the collection tank A300 to the inside of the double-layer heat exchange tube 100. The bow-shaped double-layer heat exchange tube 100 allows for a more compact pipe distribution, enabling longer pipes to be arranged on the heat exchange fins 200. Therefore, the liquid is transported over a longer distance, resulting in better heat dissipation. (Double-layer design) The copper tubes double the liquid heat exchange distance and extend the heat transfer time, significantly improving heat exchange efficiency. The coolant inside the double-layer heat exchange tube 100 flows from elbow A101 to elbow B102, during which time it is dissipated through multiple heat exchange fins 200 on the outside, and is then transported to the inside of the liquid collection tank B400 through elbow B102. The rectangular liquid collection tank B400 allows the liquid inside the liquid collection tank B400 to exchange heat, improving the heat exchange efficiency of the liquid. Subsequently, it is transferred out of the liquid collection tank B400 through the connecting pipe B402, achieving a heat exchange cycle.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
