Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle heating technology, specifically an electromagnetic induction heating vehicle-mounted phase change heat storage heating device. Background Technology
[0002] The development of new energy vehicles is rapid and promising, but due to the limitations of battery energy storage density, the driving range of electric vehicles is relatively limited compared to traditional fuel vehicles. Especially in the cold winter temperatures of northern my country, battery performance degrades significantly, leading to a sharp decrease in driving range. This characteristic hinders the further development of electric vehicles. Therefore, research on on-board phase change thermal energy storage heating devices has significant practical implications.
[0003] Compared to traditional gasoline vehicles, electric vehicles lack the waste heat from the engine, resulting in insufficient heat for the power battery during winter heating and cold start preheating. The commonly used on-board heating systems are heat pump systems and PTC electric heating systems, but these two heating methods have disadvantages such as frosting and high battery consumption, which limit their use in electric vehicles. Utility Model Content
[0004] The purpose of this invention is to provide an electromagnetic induction heating vehicle-mounted phase change heat storage heating device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An electromagnetic induction heating vehicle phase change heat storage and heating device includes a heat storage tank connected to the vehicle heating system, an electromagnetic induction coil is sleeved on the outside of the heat storage tank, and the electromagnetic induction coil is connected to the vehicle charging system and / or the vehicle battery power.
[0007] The heat storage tank contains at least one heat storage ball, which includes a high-temperature resistant shell and a phase change material disposed within the shell.
[0008] As a further embodiment of this utility model, the heat storage tank is provided with an external heat insulation layer.
[0009] As a further embodiment of this utility model: the heat storage tank is a cylindrical structure, and a flow pipe is provided inside the heat storage tank, with the heat storage ball located inside the flow pipe.
[0010] As a further embodiment of this utility model: a first flow equalization plate and a second flow equalization plate are provided in the flow pipe of the heat storage tank, and the heat storage ball is located between the first flow equalization plate and the second flow equalization plate.
[0011] As a further embodiment of this utility model: the first flow equalization plate and the second flow equalization plate are provided with flow holes, and the heat storage ball is provided in multiple ways, wherein the outer diameter of the heat storage ball is not less than the inner diameter of the flow hole.
[0012] As a further embodiment of this utility model: the circulation pipe is filled with heat exchange fluid, and the heat exchange fluid is connected to the vehicle heating system through the pipe.
[0013] As a further embodiment of this utility model: the shell of the heat storage ball is made of stainless steel, the inner wall of the shell is provided with an alumina ceramic coating, and the phase change material is aluminum-silicon alloy particles disposed inside the shell.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This application provides an electromagnetic induction coil heating device on the outside of the heat storage device. When the electric vehicle is charging, the heat generated by the electromagnetic induction coil is absorbed and stored by the aluminum-silicon alloy filled in the heat storage ball, which is used for heating the electric vehicle. This effectively reduces the battery power consumption in the electric vehicle heating system, thereby improving the electric vehicle's range in winter.
[0016] 2. This application uses electromagnetic induction for heating, which has higher energy efficiency compared to traditional heating methods; its electromagnetic field directly heats the material, thereby shortening the heating time and reducing energy consumption.
[0017] 3. This application utilizes an insulation layer on the outside of the heat storage tank to significantly slow down heat loss, effectively storing heat. When the electromagnetic induction coil stops heating, the heat storage tank retains a certain amount of heat, providing continuous and stable heating when needed. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 In this embodiment of the utility model, an electromagnetic induction heating vehicle phase change heat storage and heating device includes a heat storage tank 3 connected to the vehicle heating system, an electromagnetic induction coil 1 is sleeved on the outside of the heat storage tank 3, and the electromagnetic induction coil 1 is connected to the vehicle charging system and / or the vehicle battery power.
[0025] The heat storage tank 3 is externally provided with a heat insulation layer 2. The heat storage tank 3 has a cylindrical structure. The heat storage tank 3 has an internal circulation pipe 6, which is filled with heat exchange fluid. The heat exchange fluid is connected to the vehicle heating system through the pipe. The heat storage tank 3 has at least one heat storage ball 5, which is located inside the circulation pipe 6. The heat storage ball 5 is located between the first flow equalization plate 4 and the second flow equalization plate 7. The first flow equalization plate 4 and the second flow equalization plate 7 are provided with circulation holes. There are multiple heat storage balls 5, and the outer diameter of the heat storage ball 5 is not less than the inner diameter of the circulation hole.
[0026] The thermal storage ball 5 includes a high-temperature resistant shell 51 and a phase change material disposed inside the shell 51. The shell 51 of the thermal storage ball 5 is made of stainless steel, and the inner wall of the shell 51 is provided with an alumina ceramic coating 52. The phase change material is aluminum-silicon alloy particles 53 disposed inside the shell 51.
[0027] While the electric vehicle is charging, an external power source is simultaneously connected to the electromagnetic induction coil 1 of this embodiment via the charging equipment. During the charging process, the electromagnetic induction coil 1 electromagnetically heats the heat storage ball 5 inside the heat storage tank 3. During the heating process of the heat storage ball 5, the aluminum-silicon alloy particles 53 inside the heat storage ball 5 change from solid to liquid. Since the shell 51 of the heat storage ball 5 is made of high-temperature resistant stainless steel, the liquid aluminum-silicon alloy particles 53 are stored in the shell 51, thereby storing heat. After charging is completed, during the driving process of the electric vehicle, the heat exchange liquid of the heating system flows through the circulation pipe 6 and the through holes on the flow equalization plate through the heat storage ball 5 and exchanges heat with the heat storage ball 5. The heated heat exchange liquid flows back into the electric vehicle heating system to heat the electric vehicle.
