The present invention relates to a heat exchanger, and more particularly to a heat exchanger to adjust the amount of heat exchange medium supplied to the heat exchanger to adjust the heat exchange capacity according to the heating and cooling load.

As is generally known, an air conditioner includes a cooling system and a heating system. The cooling system is a process in which a heat exchange medium discharged by driving a compressor is circulated back to a compressor through a condenser, a receiver dryer, an expansion valve, and an evaporator. It is configured to cool the interior of the vehicle by heat exchange by the evaporator through, the heating system is configured to heat the interior by introducing heat exchange medium (engine coolant) to the heater core.

The condenser, the evaporator, the heater core, and the like, which heat exchange the heat exchange medium, are heat exchangers, and the heat exchanger receives the heat exchange medium, exchanges heat at an appropriate temperature, and then circulates the heat exchange medium.

As shown in FIG. 1, the conventional heat exchanger includes a plurality of tubes 5 having both ends fixed to upper and lower headers 1 and 3 and spaced apart from each other by a predetermined distance, and the upper and lower headers 1 and 3. 3, the upper and lower tanks (7, 9) coupled to each of the tube (5) to form a passage communicating with the end of each tube, and the heat dissipation fin (11) for widening the heat dissipation surface area between the tubes (5) It is configured with.

In the conventional heat exchanger configured as described above, the heat exchange medium supplied to the passage formed by the upper tank 7 and the upper header 1 in a state where it is mounted on an air conditioner, in particular an automobile air conditioner, receives each tube 5. After passing through the heat exchanger with the air around the heat exchanger is discharged through the passage formed by the lower tank (9) and the lower header (3).

As a conventional heat exchanger having a heat exchange as described above is provided with a heat exchange medium (cooling water of an automobile) regardless of a heating or cooling load, an additional control means is required to arbitrarily adjust the heat exchange capacity according to the heating or cooling load. For example, in the case of a heat exchanger used as a heater core of an automobile, in order to control the heat exchange capacity of the heat exchanger, a method of controlling the air flow through the heat exchanger by adjusting the number of revolutions of the blower or installing a door in front of the heat exchanger come. As described above, controlling the heat exchange force of the heat exchanger by controlling the air volume requires a separate device, so there is a problem in that no reliable control is performed.

In order to solve the above problems, Korean Patent Publication No. 170234, which is filed and registered by the present applicant, is fixed to both ends of the upper and lower headers 1 and 3 and is evenly spaced, as shown in FIGS. 2 and 3. A tube 5 arranged in the shape of the tube; a split supply means 13 connected to the upper header 1 to supply a heat exchange medium to a specific tube 5; and each tube 5 connected to the lower header 3; It consists of a lower tank (9) in communication with the end of.                         

The splitter supply means 13 includes a plurality of connection passages 15 communicating with an upper end of each tube 5 coupled to the upper header 1, and an inlet side of the connection passage 15 is within a predetermined angle range.

In order to perform heat exchange with the heat exchange medium using the heat exchanger in the above state, first, the heat transfer medium is supplied through the heat exchange medium supply pipe 21 and the rotating member rotatably installed in the heat exchange medium divider 19 ( 23 is rotated according to the load applied to the heat exchanger, and as the rotational member 23 rotates, the blocking feather 27 selectively opens and closes the inlet of the connecting passage 15 to heat exchange the tube 5. Either the medium is supplied or the heat exchange medium is supplied to the whole tube 5.

When the inlet of the connecting passage 15 is formed on both sides, the blocking feathers 27 provided on both sides of the rotating member 23 open the ends of each tube 5 at the same time to exchange heat with some of the tubes 5. The medium can be supplied, and the heat exchange capacity of the heat exchanger can be arbitrarily adjusted because the supply amount of the heat exchange medium can be adjusted by the rotation of the rotating member 23.                         

As described above, the heat exchange medium can be selectively flowed through each tube 5 of the heat exchanger, and thus its performance can be arbitrarily adjusted to easily cope with heating or cooling loads.

However, the heat exchanger has an advantage of selectively controlling the amount of the heat exchange medium, but the heat exchange medium guided by the blocking feather 27 of the rotating member 23 is biased in the tube row on one side of the heat exchanger, There is a fear that the mixing performance is lowered.

In addition, since the lower tank 9 and the return pipe (not shown) are formed by concentrating at each point, the heat exchange medium is circulated so that the temperature difference is severe at each specific point.

An object of the present invention for solving the above problems is to provide a heat exchanger that can control the heating or cooling capacity and minimize the temperature deviation by selectively adjusting or opening and closing the flow of the heat exchange medium flowing through the heat exchanger.

On the other hand, the heat exchanger 100 is shown vertically on the drawing, but when mounted on the actual air conditioner is mounted in a horizontal state is configured to enable individual temperature control of the driver's seat and the passenger seat.

This can omit the temporal door (not shown) for controlling the temperature of the driver's seat and the passenger seat in the air conditioning system of the left and right independent control method. It is possible.

That is, the upper and lower medium adjusting means 130 installed in the upper and lower tanks 115 are individually operated to adjust the amount of heat exchange medium supplied to the upper and lower flow paths 105d of the tubes 105, respectively. As a result, the temperature of the driver's seat and the passenger seat can be adjusted differently.

As described above, the present invention, by supplying the heat exchange medium to a specific tube or the entire tube by the operation of the medium adjusting means and by appropriately adjusting the amount of the heat exchange medium, the heat exchange capacity can be easily adjusted according to the cooling and heating load, Since the heat exchange medium is distributed and circulated through the specific tube or the whole tube without resistance to movement, the mixing performance and the overall heat exchange performance are improved.

In addition, each of the distribution channel, the guide guide and the supply hole is formed in the form of the diffusion in both directions with respect to the guide portion can supply the heat exchange medium to each tube constantly, it is possible to adjust the amount of the heat exchange medium in stages Fine temperature control is possible.

In addition, since the distribution channel, the guide guide, and the partition wall may be formed in various ways, the number and shape of the channel of the heat exchange medium flowing through specific tubes may be freely adjusted.

In addition, by using a tube having a "U" shaped flow path up and down temperature variations are minimized.
