Description

Heater for vehicle

More particularly, the present invention relates to a heater for a vehicle, and more particularly to a heater for a vehicle of an electric relay type, in which a heat-radiating plate in contact with a heating element inside a first housing for fixing one end of a tube and a fin, And an air flow hole which is hollow in a certain region of both sides in the air flow direction is formed, thereby improving heat transfer efficiency and heat transfer efficiency.

Among the heating means provided in the interior of the vehicle, the heating means for heating the interior of the vehicle is designed to heat the outside of the vehicle by heating the outside air while circulating the heater core through a 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 up the heat exchanging medium for cooling the engine at the time of starting the automobile. Therefore, in a vehicle equipped with a diesel engine in 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 this problem, a Pitty seed heater using a Pitty device can be used as a heating device. Here, the PTC (Positive Temperature Coefficient) heater is a heater made of a PTI device, and the PTI device is one of widely used electric devices as a heating element for a vehicle auxiliary heater. In general, the resistance does not change with temperature, but the resistance of the device is rapidly increased when the temperature rises at a certain temperature. If the temperature rises above a certain level, the resistance becomes large, and the amount of current that can flow through the resistor becomes small. As the current decreases, the amount of heat is reduced and the temperature drops again. When the temperature drops, the resistance increases and the heat generation starts. Therefore, if a Pitty seed heater is used, a certain temperature can be maintained. In the case of being used as a vehicle auxiliary heater, the cooling water is not heated during the winter season and the start of the vehicle. So that the heating performance of the vehicle is compensated.

1, a heat source unit 11 including a terminal unit for power supply and a heat dissipation unit that generates heat by receiving power from the terminal unit, And a housing 20 for covering and protecting the terminal portion, the heat source portion 11, and the heat radiation portion 12.

A plurality of radiating holes are formed on the surface of the housing so that the heat of the radiating part 12 can be effectively radiated to the outside of the housing. When the air passes through the radiating hole, Rise.

On the other hand, the PTC devices of the Pittsy heaters usually operate in three to four steps in sequence. In order to control the number of stages, the electric relay type, which is formed by including a control unit in which a FET device or a PWM device is present in the PT And a mechanical type driven by a vehicle-side ECU and a relay.

At this time, if it is difficult for the vehicle-side ECU to control the PTC or the external relay, it is necessary to apply the electric relay type Pettish heater to the automotive air conditioning system.

FIG. 2 shows a Peltier heater 30 of an electric relay type. The Peltier heater of an electric relay type has a structure in which a heat radiating plate 31 is arranged in a direction of air flow to cool a FET device or a PWM device disposed in the housing, As shown in FIG.

In this case, since the heat sink is disturbed by the air flow as much as the space in which the heat sink is formed, the heat sink may adversely affect heat exchange performance and NVH (noise, vibration, harshness) of the heat sink. There is a disadvantage that the size of the heat exchange area can be made larger.
