Description

{HEATER FOR VEHICLES}

More particularly, the present invention relates to a heater for a vehicle, and more particularly, to a heater for a vehicle, and more particularly, to a heater for a vehicle, And can fix the supporting portion and the heat generating portion by a simple method using a fixing member, thereby improving the productivity of the vehicle.

The heating means is used for raising the temperature of the outside, and means using various methods have been proposed and are also used for various purposes.

Particularly, among the heating means provided in the vehicle engine room, the heating means for heating the room is configured to heat the outside of the vehicle by heating the outside air while circulating the heater core through the heat exchange medium for lowering the temperature of the engine.

However, since the diesel engine has a high heat exchange rate, it takes a long time to heat the heat exchanging medium for cooling the engine at the initial start of the automobile, compared to the gasoline engine.

Therefore, in a vehicle equipped with a diesel engine in the winter, the heating of the heat exchange medium is delayed after the initial startup and the initial indoor heating performance is deteriorated.

In order to solve the above-mentioned problems, there has been proposed a vehicular air heater which directly heats air blown to a room side by various means.

Such an air heating type heater is advantageous in that the heating performance can be further improved by directly heating the air. However, due to the trend of miniaturization and high efficiency, it takes a space equal to the size of the heater in a situation where it is difficult to secure sufficient space in the engine room Which may cause the miniaturization to be hindered.

Particularly, in the case of a cartridge heater using a nichrome wire, it is difficult to control the temperature, and when air is not blown to the heater side, there is a fear of overheat, insulation problem due to high voltage may occur, There is a problem.

A vehicle air conditioner using a PTC (Positive Temperature Coefficient) heater has been proposed in Japanese Patent Application Laid-Open No. 2009-255739, and a conventional PTC heater is shown in Fig.

1, the PTC heater shown in FIG. 1 includes a heat source unit 11 formed of a PTC device, a heat radiation unit 11 for effectively releasing heat while being in contact with the heat source unit 11, And a housing 20 that covers and protects the terminal unit, the heat source unit 11, and the heat radiation unit 12.

The conventional PTC heater may have some differences in detail, but since the heat source portion is formed in parallel with the air flow direction, the formation area of the heat source portion directly affects the heat generating performance and accordingly, the thickness of the PTC heater There is a limit to reducing the number

Particularly, in the case of a PTC heater, since an electrical problem may occur when the heat radiation condition is poor, a heat dissipation part (generally, a heat dissipation fin) must be formed. Therefore, manufacturing and assembly processes of the heat dissipation part are troublesome, There is a problem that the durability of the entire PTC heater may deteriorate.

Accordingly, it is possible to improve the heating performance by improving the heat exchange efficiency by directly heating the air while smoothly flowing the air, and it is possible to miniaturize, control is easy, and problems caused by overheating are prevented, The development of a heater having a high temperature is required.
