As described above, conventional car heaters use the cooling water of the water-cooled engine to heat the vehicle interior, so the vehicle interior cannot be heated until the water-cooled engine is started and the water-cooled engine is warmed up. This time generally takes about 5 to 15 minutes when the outside air is around 0°C, and about 20 to 30 minutes when the outside air is around -20°C. Therefore, conventional car heaters have the disadvantage that occupants feel cold while the engine warms up.

When the water-cooled engine is warm, the coolant that has passed through the water-cooled engine and been warmed heats the main heat storage material and the temperature-ensuring heat storage material when passing through the heat storage heat exchange device. When the heat storage agent enclosed in these heat storage materials is heated, it changes from a solid phase to a liquid phase and stores heat in the form of latent heat.

熱の形で蓄熱されている。 In general substances, the melting point and freezing point are the same temperature, but the heat storage agent of the main heat storage material and temperature guarantee heat storage material maintains a liquid phase without solidifying even if the temperature becomes lower than the melting point. A so-called supercooling phenomenon occurs. The temperature of the main heat storage material and the temperature guaranteed heat storage material eventually becomes the same as the outside temperature due to heat radiation. However, the heat released at this time is limited to sensible heat, and the main heat storage material and the temperature guaranteed heat storage material still store heat in the form of latent heat.

The heat storage agent, which is the main heat storage material, changes from a liquid phase to a solid phase, and at this time, releases the heat stored as latent heat.
As a result, the cooling water is quickly warmed up within the heat storage heat exchange device. This heated cooling water is sent to a heat exchanger and is used as a heat source for heating the passenger compartment.

る。 In addition, if the heat storage agent sealed in the heat storage material is supercooled too much, it will naturally change from a liquid phase to a solid phase.
The heat that was previously stored as latent heat is released. However, in the case of the car heater according to the present invention, before the main heat storage material naturally radiates heat due to supercooling, the second supercooling release device operates to release the supercooling of the temperature guaranteed heat storage material, so that the temperature guaranteed heat storage material becomes Heat is generated, thereby heating the main heat storage material, and preventing the main heat storage material from naturally releasing heat due to overcooling.

This heat storage agent turns into a gel when heated to 60°C and stores latent heat. Once the latent heat is stored, it is not released even if the heat storage agent cools down.
Therefore, the heat storage agent maintains its gel state even when its temperature becomes the same as room temperature. Therefore, the heat storage material can store heat in the form of latent heat for a long period of time without insulation. On the other hand, when an appropriate stimulus is applied to the heat storage agent of the heat storage material, the heat storage agent is activated and returns to a solid state. At this time, heat of 58℃ is released.

て極めて有用である。[Effects of the Invention] The car heater according to the present invention can heat the passenger compartment even when the engine is not warmed up immediately after the engine is started. Particularly in cold regions, it takes a long time for the engine to warm up in the winter, so it is extremely useful as a preliminary heating until the engine warms up.
