Abstract
Description
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.

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
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.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a heater for a vehicle of an electric relay type, which has a tube inserted therein and a first housing for fixing one end of the fin, A heat radiating plate in contact with the heat generating element is mounted in parallel with the air flowing direction and an air flow hole is formed in a predetermined region of both sides in the air flowing direction to increase the heat transfer area to improve heat exchange efficiency.

A heater for a vehicle according to the present invention is an electric relay type vehicle heater, in which a heat sink, which is in contact with a heating element, is installed in a first housing for fixing one end of a tube and a pin into which the Pitti element is inserted, And an air flow hole is formed in the air flow direction in a certain region of both sides in the air flow direction, so that the heat transfer area is increased and the heat exchange efficiency can be improved.
That is, in the automotive heater according to the present invention, the ventilation resistance is increased due to the heat radiating plate which has been mounted on the front surface in the air flow direction, the heat transfer area is reduced by the area of the heat radiating plate and the heat exchanging efficiency is lowered. The heat sink is disposed inside the first housing in which the control board having the heating element mounted therein is guided and the air is guided to the first heat sink inside the housing By forming the air flow holes, the ventilation resistance can be reduced, heat exchange efficiency can be improved, and manufacturing cost can be reduced.
In the vehicle heater of the present invention, since the heat radiating plate is accommodated in the first housing, when the heat transfer area is the same as that of the conventional vehicle heater, the size of the heat radiating plate is reduced, There are advantages.
In addition, according to the vehicle heater of the present invention, as the air passing through the heat radiating plate flows into the HVAC, the heating performance can be further improved.
