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 tube to adjust the heat exchange capacity according to the heating and cooling load appropriately, wherein the flow of the heat exchange medium flowing through the heat exchanger It controls the heating or cooling capacity by adjusting or opening and closing the heat exchange medium to distribute the heat exchange medium evenly to the heat exchanger and at the same time maintain the heat exchange medium flow rate and flow rate to the tube side to improve the left and right temperature difference and improve the heat exchange performance.

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 interval, and the upper and lower headers 1 and 3, respectively. Upper and lower tanks 7 and 9 are coupled to form passages communicating with the ends of the respective tubes 5, and heat dissipation fins 11 are provided between the tubes 5 to increase the heat dissipation surface area.

The conventional heat exchanger configured as described above has one side in which a heat exchange medium supplied to a passage formed by the upper tank 7 and the upper header 1 is partitioned by a baffle while being mounted in an air conditioner, in particular an automobile air conditioner. After performing heat exchange with the air around the heat exchanger while passing through the tubes (5), the U-turn is made in the passage formed by the lower tank (9) and the lower header (3), this time passing through the other tubes (5) again. The heat exchange is performed and discharged through a passage formed by the upper tank 7 and the upper header 1.

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.

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, Not only was the mixing performance deteriorated, there was a problem that the left and right temperature difference of the heat exchanger was severely generated.

An object of the present invention for solving the above problems is to provide a heat exchanger to selectively control or open and close the flow of the heat exchange medium flowing through the heat exchanger to control the heating or cooling capacity and to distribute the heat exchange medium evenly to the heat exchanger. have.

Another object is to form a heat exchange medium distribution hole communicating with the tubes divided by a certain number in proportion to the number of tubes to maintain a constant amount and flow rate of the heat exchange medium flowing to the tube side to improve the left and right temperature difference and heat exchange To provide a heat exchanger with improved performance.

The amount of heat exchange medium passing through is supplied in proportion to the number of the corresponding tube 105 to be evenly distributed to each tube 105 and at the same time the amount of heat exchange medium and flow rate flowing along the tube 105 is maintained to improve the left and right temperature difference And heat exchange performance is improved.                     

In addition, FIG. 13 shows an example formed by modifying not only the size of the distribution hole 170 but also the arrangement / shape of the distribution hole 170 and the distribution channel 190. .

In addition, as the distribution holes 170 and the distribution channel 190 are variously modified, the number of tubes communicating with the media distribution means 110 and the respective supply holes 145 may also be variously modified. will be.

On the other hand, the size of the distribution passage 190 and the plurality of supply holes 145 formed in the media distribution means 110 communicating with the distribution hole 170 is also formed in a size proportional to the number of the corresponding tube 105 in communication. It would be desirable to.

As described above, according to the first embodiment of the present invention, the upper and lower headers 101 and 103 are coupled to both ends of the plurality of tubes 105 and the return pipe 140, respectively, and the upper header 101 The upper tank 115 is provided with the media distribution means 110 and the medium adjusting means 130, and the lower header 103 is provided by installing the lower tank 135.

Therefore, when the heat exchange medium is supplied to the guide unit 165 through the medium supply pipe 120 of the upper tank 115, the heat exchange medium is directly through the bypass hole 185 under the control of the medium adjusting means 130. Bypassed to the recovery pipe 125 or flows through the distribution hole 170 along the plurality of tubes 105, heat exchange with the outside air, and then return through the return pipe 140 to discharge to the medium recovery pipe 125 Will be.

Hereinafter, the circulation process of the heat exchange medium will be described in more detail.                     

When the rotational auxiliary body 225 is rotated at a specific angle through a control switch in the course of circulating the heat exchange medium, some of the distribution holes 170 of the distribution holes 170 are opened by the rotation of the valve body 195. The open distribution hole 170 communicates with the distribution channel 190 and the supply hole 145, and the supply hole 145 is connected to a specific tube 105 separated by a predetermined number by both partition walls 160. Communicating.

Therefore, the heat exchange medium supplied through the medium supply pipe 120 flows along a specific tube 105 in communication with the distribution hole 170 opened by the rotation of the valve body 195, thereby actively performing heat exchange with external air. After that, the lower tank 135 is moved.

The heat exchange medium moved to the lower tank 135 moves to the upper tank 115 through the return pipe 140, and the heat exchange medium moved to the upper tank 115 passes through the recovery induction hole 180. It is discharged to the recovery pipe (125).

As described above, when the valve body 195 rotates at a specific angle, the auxiliary valve body 200 operated by the link 205 is located between the recovery induction hole 180 and the bypass hole 185 and is the recovery induction hole. When the heat exchange medium returned through the return pipe 140 moves to the medium recovery pipe 125 because the 180 and the bypass hole 185 are not completely blocked, the guide portion (120) is provided through the medium supply pipe 120. A portion of the heat exchange medium supplied to 165 flows directly into the medium recovery pipe 125 through the bypass hole 185.

That is, the more the distribution hole 170 is opened by the rotation of the valve body 195, the auxiliary valve body 200 moves toward the bypass hole 185 and bypasses through the bypass hole 185. As the flow rate decreases, the less the distribution hole 170 is opened, the more the auxiliary valve body 200 moves toward the recovery induction hole 180 and the bypass flow rate increases through the bypass hole 185.

In addition, when the rotational auxiliary body 225 is completely rotated, the entire distribution hole 170 is opened by the rotation of the valve body 195, and the distribution hole 170 is the distribution channel 190 and the supply hole ( 145 is in communication with the entire tube 105.

Therefore, the heat exchange medium flows along the entire tube 105 through the distribution passage 190 and the supply hole 145 through the distribution hole 170 which is entirely open, and then performs active heat exchange with the outside air, and then the lower tank. Go to (135).

The heat exchange medium moved to the lower tank 135 is returned to the upper tank 115 through the return pipe 140, and the heat exchange medium returned to the upper tank 115 is discharged to the medium recovery pipe 125. will be.

As described above, when the valve body 195 is completely rotated and the entire distribution hole 170 is opened, the auxiliary valve body 200 completely opens the recovery induction hole 180 and the bypass hole 185 completely shuts off. Accordingly, all of the heat exchange medium supplied through the medium supply pipe 120 flows to the tube 105 side.

On the contrary, when the valve body 195 rotates to block the entire distribution hole 170, the auxiliary valve body 200 completely opens the bypass hole 185 and completely recovers the induction hole 180. All of the heat exchange medium supplied through the medium supply pipe 120 is discharged directly to the medium recovery pipe 125 through the bypass hole 185.

On the other hand, the guide portion 165 is formed in the center of the heat exchanger 100, and the distribution passage 190, the guide guide 150, and the supply hole 145 are centered around the guide portion 165 in both directions. By forming the diffusion, the heat exchange medium can be arbitrarily adjusted to each tube 105 during the operation of the valve body 195, thereby improving the mixing performance.

In addition, since the movement path of the heat exchange medium can be freely specified, temperature linearity can be stably adjusted, and each tube (as the distribution channel 190, the guide guide 150, the supply hole 145, etc. are formed in various forms). The supply of the heat exchange medium to 105 can be freely set, and the supply amount of the heat exchange medium can be preferentially identified by forming the partition wall 160 at an appropriate position based on the supply hole 145.

FIG. 14 is a plan view showing a heat exchanger according to a second embodiment of the present invention, and only a configuration and operation different from those of the first embodiment will be described, and repeated descriptions will be omitted.

The cover 220 and the rotating aid 225 is coupled to the upper end of the rotating body 210 protruding to the outside of the cover 220 and connected to an actuator (not shown).

The medium adjusting means 130 according to the second embodiment has a structure in which the link 205 and the auxiliary valve body 200 are deleted from the medium adjusting means 130 of the first embodiment. Detailed description will be omitted.

Corresponding to the structure of the medium adjusting means 130, the recovery guide hole for communicating the recovery unit 175 and the media recovery tube 125 on one side with the media recovery tube 125 of the upper tank 115 in between. 180 is formed and the other side is formed to block the communication between the guide portion 165 and the medium recovery pipe (125).

Therefore, when the rotational auxiliary body 225 is rotated at a specific angle through the control switch in the process of circulating the heat exchange medium, the distribution hole of some (or all) of the distribution holes 170 by the rotation of the valve body 195. 170 is opened, the open distribution hole 170 is in communication with the distribution channel 190 and the supply hole 145, the supply hole 145 is divided into a predetermined number by both side partitions 160. In communication with a particular tube 105.

Therefore, the heat exchange medium supplied through the medium supply pipe 120 flows along a specific tube 105 in communication with the distribution hole 170 opened by the rotation of the valve body 195, thereby actively performing heat exchange with external air. After that, the lower tank 135 is moved.

The heat exchange medium moved to the lower tank 135 moves to the upper tank 115 through the return pipe 140, and the heat exchange medium moved to the upper tank 115 passes through the recovery induction hole 180. It is discharged to the recovery pipe (125).

 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, The heat exchange medium is distributed and circulated through a specific tube or the entire tube without resistance to movement, thereby improving mixing performance and overall heat exchange performance.

In addition, by forming the medium distribution means made of a rubber material or a synthetic resin material, heat transfer between the heat exchange medium flowing to the tube side and the heat exchange medium bypassed is minimized, and the respective distribution passages, guide guides, and supply holes are formed around the guide part. It is formed in the form of diffusion in both directions can be supplied to the heat exchange medium to each tube constantly.

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 flow path of the heat exchange medium flowing through specific tubes may be freely adjusted.

In addition, by forming a heat exchange medium distribution hole communicating with the tube divided by a certain number in proportion to the number of tubes, the amount and flow rate of the heat exchange medium flowing to the tube side is kept constant to improve the left and right temperature difference and heat exchange performance This is improved.
