Description

Heating device for automobiles {heater for a car}

The present invention relates to a heating device for automobiles, and in particular, by immersing the auxiliary heating unit in the lower portion of the main heater, it is possible to reduce the warm-up time due to low-temperature cooling water generated at the beginning of the start of the winter vehicle.

In general, an air conditioner is installed in the vehicle to keep the indoors contaminated by the breathing of passengers or the external temperature change in a fresh state or to maintain a comfortable interior by maintaining a temperature suitable for activities.

Such an air conditioning apparatus is typically provided with a blower unit composed of a fan case coupled to a blower fan and a motor case accommodating a blower motor so as to introduce internal and external air required for cooling and heating.

In addition, the front of the blower unit is provided with an evaporator for converting the air supplied by the heat exchange to the cold by receiving the refrigerant passing through the compressor, the capacitor, the receiver dryer and the expansion valve.

In addition, the front of the evaporator is used for cooling the engine is equipped with a heating device in which the high temperature cooling water flows to perform the heating, and the temperature control door is provided between the evaporator and the heater core phase to ensure proper mixing of cold and warm air. Allows you to control the final temperature discharged into the room.

And the front of the heater core is composed of a module case having a valve for supplying the temperature control air in the direction of the floor, vent and defroster in the room.

The heating device is typically provided to form a rectangular shape by forming a plurality of cooling fins between the tube plate having a predetermined length, the upper portion of the tube plate is formed with a tank for storing the fluid paired with the header, The outermost part of the tube plate is composed of a side plate having a role of fixing the cooling fins and protecting them at the same time.

In addition, the upper portion of the tank is configured such that inlets and outlets for inflow and outflow of cooling water have a predetermined length.

In the air conditioner having such a configuration, the evaporator removes moisture and dust contained in the refrigerant converting the refrigerant into a gas of high temperature and high pressure, a condenser that liquefies the compressed high temperature and high pressure gas, and the moisture and dust contained in the refrigerant via the condenser. The refrigerant required for this purpose is supplied to the receiver dryer from an expansion valve that is shaped like frost of low temperature and low pressure to facilitate heat exchange.

The refrigerant supplied to the evaporator generates cold air by exchanging heat with the latent latent heat, and the refrigerant passing through the evaporator is repeatedly circulated to the compressor to cool the inside of the vehicle.

On the other hand, if you want to heat the inside of the vehicle, the high temperature cooling water used to cool the engine may be circulated to the heating apparatus. That is, in the process of circulating coolant through the inlet, the tank, the tube plate, and the outlet, the high temperature of the engine is cooled, and heat exchange with the outside air is performed through cooling fins formed on both sides of the tube plate, and the heat exchanged air is driven by the blower fan. As it is discharged into the vehicle, heating can be performed.

However, since the temperature of the coolant is in a very low state at the beginning of the start of the engine in the winter during the heating of the car, there is a problem that the warm-up time is delayed.

In order to solve such a problem, a separate auxiliary heating device is used. The auxiliary heating device is used to coat a heating element on the surface of the tube when the cooling water is heated. This was a very complicated problem.

In addition, an electric heater is used to heat the air, and there is a problem of insulation in the process of mounting or fixing the electric heater to a metal heating device.

The present invention has been made in order to solve such a problem, by immersing the auxiliary heating portion in the lower portion of the main heater, to reduce the warm-up time due to the low temperature cooling water generated during the initial start of the vehicle heating device for automobiles The purpose is to provide.

In order to achieve the above object, the present invention fixes a plurality of tube plates and cooling fins so as to be stacked in parallel between the headers, and prevents the cooling fins from being damaged by a plurality of side plates on the outer side thereof. In the heating device for a differential vehicle having a tank, the auxiliary heating part is formed by inserting a through hole in the lower part of the tank, and the auxiliary heating part provides a heating device for a vehicle, characterized in that configured to be fixed to the through hole by brazing. The object is achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the heating device A for automobiles according to the present invention includes a header plate 2 and a 2 'having a tube plate 1 having a plurality of cooling fins 11 and 12 formed up and down. ), And the side plates 3 are provided on both sides thereof to prevent the cooling fins 11 from being damaged.

In addition, the headers 2 and 2 'are provided with tanks 4 and 4' for forming a predetermined space therein and storing the coolant in pairs, and the tank 4 has an inlet 41 ) And outlet 42 are integrally formed in the same manner as in the prior art.

The present invention is configured to prevent the low-temperature phenomenon of the cooling water generated in the initial start of the engine in winter by inserting the auxiliary heating portion 5 in the tank 4 ', and to shorten the warm-up to heat the vehicle quickly. .

To this end, the auxiliary heating part 5 is provided to be inserted and fixed in the through hole (4 ") formed in the lower portion of the tank (4 '), the auxiliary heating part (5) is a way to maintain the airtight The inserted through hole 4 "is provided by brazing.

As shown in FIG. 2, the auxiliary heating unit 5 inserts a heating wire 52 electrically connected to a power source and a switch not shown in the heating body 51, and the inside of the heating body 51. And an insulation material 53 is inserted between the heating wire 52 and the heating wire 52.

In addition, the edge of the heating body 51 is formed to the edge 54, the edge 54 is formed of an aluminum material of the same material as the tank 4 'is configured to facilitate brazing.

The heating device configured as described above operates a switch (not shown) after starting the engine, and power is applied to the heating wire 52 and high temperature heat is generated. The generated heat is heated through the insulating material 53. By heating the coolant flowing through the tank 4 'and flowing in the tank 4', the temperature of the coolant which is low temperature can be raised rapidly to shorten the initial heating or warming up.

At this time, between the edge 54 and the through hole 4 "formed in the tank 4 'is fixed by blazing, thereby making it airtight and preventing leakage.
