Description

Technical Field

[0001] This utility model relates to the field of battery heating and cooling, specifically to a hot and cold plate for preheating new energy battery packs. Background Technology

[0002] Traditional automobiles rely on gasoline for operation, but with the development of automobiles, many electric vehicles have emerged. However, due to seasonal changes, battery charging and discharging can cause overheating and generate a large amount of heat. If this heat cannot be dissipated in time, the battery temperature will continue to rise, affecting battery performance and lifespan. A hot plate / cooler plate uses coolant in its internal channels to lower the battery temperature. In low-temperature environments, battery performance is also affected. To improve battery performance under low-temperature conditions, the hot plate / cooler plate can also be used to preheat the battery, raising its temperature to a suitable operating temperature.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1As shown, the preheating plate for a new energy battery pack in this application is composed of a heating and cooling plate 1, a heating and cooling groove 10, a guide hole 11, a guide groove 12, a fixing plate 2, a heating device 3, a heating copper pipe 30, a first guide pipe 31, a first return pipe 32, a cooling device 4, a connecting pipe 40, a second guide pipe 41, and a second return pipe 42.

[0021] like Figure 1 and 3 As shown, the heating plate 1 is held between two batteries, allowing for rapid heating and cooling while maintaining stability and preventing tilting. The heating plate 1 includes a heating groove 10, a guide hole 11, and a guide channel 12. The heating groove 10 is rectangular and its width is two to three times that of the guide hole 11 or the guide channel 12. Multiple rows of the heating groove 10 are connected in series, with both open ends on the same side. The guide hole 11 is located below the guide channel 12. Each open end of the heating groove 10 has a guide hole 11 and a guide channel 12. The guide hole 11 is an opening slot connecting to the heating groove 10, while the guide channel 12 is a through hole connecting to the heating groove 10. After the heating copper tube 30 is installed, the right side of the heating plate 1 is sealed to the left side by the fixing plate 2.

[0022] like Figure 1 and 2 As shown, the heating device 3 includes a heating copper tube 30, a guide pipe 31, and a return pipe 32. The heating copper tube 30 is installed in the heating and cooling tank 10, while its inlet and outlet are located in the guide pipe 12. After installation, there is still a gap between the heating copper tube 30 and the guide pipe 12, which can be sealed with sealant to prevent coolant from overflowing from the heating and cooling tank 10. The inlet and outlet of the heating copper tube 30 are fixedly connected to the guide pipe 31 and the return pipe 32, respectively. Molten iron can be added to the heating copper tube 30. The molten iron enters the heating copper tube 30 from the guide pipe 31 and exits from the return pipe 32, thus realizing the circulating heating of the molten iron.

[0023] like Figure 1 and 2 As shown, the cooling device 4 includes a connecting pipe 40, a second guide pipe 41, and a second return pipe 42. Several connecting pipes 40 are provided, one end of which is fixedly connected to the guide hole 11, and the other end is fixedly connected to the second guide pipe 41 and the second return pipe 42. Coolant enters the heating and cooling tank 10 through the second guide pipe 41 and exits through the second return pipe 42, thus achieving cyclic cooling of the battery.

[0024] In summary, one end of the flow guide pipe 31 and the return pipe 32 are closed, and the other end is connected to the heater. One end of the flow guide pipe 41 and the return pipe 42 are closed, and the other end is connected to the cooler.

[0025] This product is controlled by the vehicle's built-in control unit during operation, and its specific working conditions are dominated by it.

[0026] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
