Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and more specifically, to a radiator for an air conditioning system. Background Technology

[0002] Currently, most radiators on the market use a single tube to transport the heat carrier, i.e., the single tube is arranged in an S-shape and fins are set on the single tube for heat dissipation. However, single tube heat dissipation has a drawback: the temperature difference between the inlet and outlet of the single tube is large. This is because the heat carrier inside the single tube flows along the single tube, which leads to uneven heat dissipation of the heat sink itself. How to improve the uniformity of heat dissipation of the radiator as a whole is the technical problem that this invention aims to solve. Utility Model Content

[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, this utility model provides a radiator for an air conditioning system, comprising: a heat carrier supply pipe, a heat carrier return pipe, and a radiant heat sink. The radiant heat sink consists of a radiant heat sink plate and a plurality of first fins connected to the radiant heat sink plate. At least one first pipe is disposed inside the radiant heat sink. The heat carrier supply pipe is connected to the first pipe, and the outlet end of the first pipe is connected to the heat carrier return pipe. The radiant heat sink plate radiates heat.

[0005] Preferably, the heat carrier supply pipe is located at the upper end of the radiator, and the heat carrier supply pipe includes two or more branch pipes; the heat carrier return pipe is located at the lower end of the radiator, and the heat carrier return pipe includes two or more return branch pipes.

[0006] Preferably, it also includes a fin layer, wherein at least one second tube is provided in the fin layer, the heat carrier supply tube is connected to the second tube, the outlet end of the second tube is connected to the heat carrier return tube, and a plurality of second fins are provided on the outside of the second tube, wherein the first fins and the second fins are arranged in parallel.

[0007] Preferably, the thickness of the first fin is greater than the thickness of the second fin.

[0008] Preferably, the surfaces of the first fin and the second fin are wavy.

[0009] Preferably, it further includes a layer plate connector, the fin layer and the radiant heat sink are connected by the layer plate connector, the layer plate connector is disposed on the side of the fin layer and the radiant heat sink, and the heat carrier supply pipe and the heat carrier return pipe are both connected to the first pipe and / or the second pipe through the layer plate connector.

[0010] Preferably, the first tube and the second tube are arranged in parallel, and both the first tube and the second tube are arranged in the normal direction to the layer plate connector.

[0011] Preferably, the radiator has a first decorative strip with openwork on the upper and lower sides, and a second decorative strip on the left and right sides.

[0012] Preferably, the heat carrier is Freon.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] The surface of the radiant heat sink is a radiant heat sink plate, and the back of the radiant heat sink is provided with a first fin plate. The first fin plate is connected to the surface of the radiant heat sink. The high-temperature heat carrier in the first tube transfers heat to the first fin plate through the first tube wall. The first fin plate transfers heat to the surface of the radiant heat sink, and the surface heat sink plate radiates heat. The high-temperature heat carrier in the second tube transfers heat to the second fin plate through the second tube wall. This radiator is a windless radiant heat sink. In order to increase the heat dissipation of the radiator, the surfaces of the first fin plate on the radiant heat sink and the second fin plate on the fin layer are designed to be wavy. This not only increases the heat dissipation area, but also forms a convection heat dissipation similar to the "chimney effect", which accelerates the heat dissipation speed. The high-temperature heat carrier is diverted through the branch pipe at the top of the radiator and enters the finned layer and radiant heat sink through the pipe at the top of the finned layer and radiant heat sink. It flows from top to bottom through the pipe of the finned layer and radiant heat sink and flows out from the bottom of the finned layer and radiant heat sink after being merged through the return branch pipe at the bottom of the radiator. The high-temperature heat carrier dissipates heat during the process of flowing through the pipe of the finned layer and radiant heat sink. The multi-pipe structure solves the problem of uneven surface temperature of the radiator.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0026] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] like Figures 1-7 As shown, this utility model provides a radiator 100 for an air conditioning system, including: a heat carrier supply pipe 1, a heat carrier return pipe 2, and a radiant heat sink 3. The radiant heat sink 3 is composed of a radiant heat sink plate 31 and a plurality of first fins 32 connected to the radiant heat sink plate 31. At least one first pipe 33 is provided inside the radiant heat sink 3. The heat carrier supply pipe 1 is connected to the first pipe 33. The outlet end of the first pipe 33 is connected to the heat carrier return pipe 2. The radiant heat sink plate 31 radiates heat.

[0028] The heat carrier supply pipe 1 is located at the upper end of the radiator 100, and includes two or more branch pipes 8. The heat carrier return pipe 2 is located at the lower end of the radiator 100, and includes two or more return branch pipes 9. The radiator also includes a finned layer 4, within which at least one second pipe 41 is disposed. The heat carrier supply pipe 1 communicates with the second pipe 41, and the outlet end of the second pipe 41 communicates with the heat carrier return pipe 2. Several second fins 42 are disposed on the outside of the second pipe 41, and the first fin 32 is arranged parallel to the second fins 42. The thickness of the first fin 32 is greater than the thickness of the second fin 42. The surfaces of the first fin 32 and the second fin 42 are wavy. It also includes a layer plate connector 5, through which the fin layer 4 and the radiant heat sink 3 are connected. The layer plate connector 5 is disposed on the side of the fin layer 4 and the radiant heat sink 3. The heat carrier supply pipe 1 and the heat carrier return pipe 2 are both connected to the first pipe 33 and / or the second pipe 41 through the layer plate connector 5. The first pipe 33 and the second pipe 41 are arranged in parallel, and both the first pipe 33 and the second pipe 41 are arranged in the normal direction to the layer plate connector 5. The radiator 100 has a hollowed-out first decorative strip 6 on its upper and lower sides, and a second decorative strip 7 on its left and right sides.

[0029] The working principle and beneficial effects of the above technical solution are as follows: The surface of the radiant heat sink 3 is a radiant heat sink plate 31, and the back of the radiant heat sink 3 is provided with a first fin plate 32. The first fin plate 32 is connected to the surface of the radiant heat sink 3. The high-temperature heat carrier in the first tube 33 transfers heat to the first fin plate 32 through the wall of the first tube 33. The first fin plate 32 transfers heat to the surface of the radiant heat sink 3, and the radiant heat sink 31 radiates heat. The high-temperature heat carrier in the second tube 41 transfers heat to the second fin plate 42 through the wall of the second tube 41. This radiator is a windless radiant heat sink. In order to increase the heat dissipation of the radiator, the surfaces of the first fin plate 32 on the radiant heat sink 3 and the second fin plate 42 on the fin layer 4 are designed to be wavy, which not only increases the heat dissipation area, but also forms a convection heat dissipation similar to the "chimney effect", thus accelerating the heat dissipation speed. The high-temperature heat carrier is diverted by the branch pipe 8 at the top of the radiator and enters the finned layer 4 and radiant heat sink 3 from the upper pipe. It flows from top to bottom through the pipe of the finned layer 4 and radiant heat sink 3, and then flows out from the bottom of the finned layer 4 and radiant heat sink 3 after being converged by the return branch pipe 9 at the bottom of the radiator. The high-temperature heat carrier dissipates heat during the process of flowing through the pipe of the finned layer 4 and radiant heat sink 3. The multi-pipe structure solves the problem of uneven surface temperature of the radiator.

[0030] Furthermore, the connection method between the first and second pipes of this novel invention can be freely combined, taking the connection between the heat carrier supply pipe 1 and the finned layer 4 as an example.

[0031] In the first embodiment, the second tube is at least A tubes, and they are arranged in parallel. From the second tube furthest from the heat carrier return tube towards the heat carrier return tube, they are respectively the 1st tube, the 2nd tube... the Ath tube, where A is not less than 2.

[0032] The first tube has at least B tubes, which are arranged in parallel. From the first tube furthest from the heat carrier return tube towards the heat carrier return tube, they are the 1st tube, the 2nd tube... the Bth tube, where B is not less than 2.

[0033] The heat transfer fluid supply pipe is divided into n branches, with the n branches being the 1st branch, the 2nd branch, ..., the nth branch, and n is not less than 2.

[0034] The first branch pipe is connected to the inlet end of the xth second pipe, and the outlet end of the xth second pipe is connected to the inlet end of the yth first pipe.

[0035] The second branch pipe is connected to the inlet end of the (x+m)th second pipe, and the outlet end of the (x+m)th second pipe is connected to the inlet end of the (y+m)th first pipe.

[0036] The nth branch pipe is connected to the inlet end of the x+(n-1)*m second pipe, and the outlet end of the x+(n-1)*m second pipe is connected to the inlet end of the y+(n-1)*m first pipe.

[0037] Where 1≤x≤A; 1≤y≤B; x<y; m≥1.

[0038] like Figure 6 As shown, taking a heat transfer fluid supply pipe as a three-branch system (three-way flow) as an example, n=3, m=1, the three branches are the first branch, the second branch, and the third branch. Assume:

[0039] The first branch pipe is connected to the inlet end of the second branch pipe, the second branch pipe is connected to the inlet end of the third branch pipe, and the third branch pipe is connected to the inlet end of the fourth branch pipe.

[0040] The outlet end of the second pipe is connected to the inlet end of the fourth pipe, the outlet end of the third pipe is connected to the inlet end of the fifth pipe, and the outlet end of the fourth pipe is connected to the inlet end of the sixth pipe.

[0041] like Figure 6As shown, this completes the three-way flow splitting of the heat transfer system from one branch to three. With three parallel pipes, the heat transfer fluid in each branch can flow back and forth between the second and first pipes. Afterward, it is only necessary to ensure that the three split pipes are connected at the heat transfer fluid return pipe. This achieves a one-to-three parallel loop, allowing the heat transfer fluid to flow through both the finned layer and the radiant heat sink, thus distributing heat to different locations and achieving uniform heat dissipation.

[0042] Furthermore, the outlet end of the y-th first pipe is connected to the inlet end of the x+z-th second pipe;

[0043] The outlet end of the (y+m)th first pipe is connected to the inlet end of the (x+m+z)th second pipe;

[0044] The outlet end of the first pipe of the y+(n-1)*mth ...

[0045] …

[0046] And so on, all of them eventually connect to the heat transfer fluid return pipe;

[0047] z≥0.

[0048] z is the number of second tubes that are spaced between the x+m+zth second tube and the x+(n-1)*mth second tube.

[0049] For example Figure 6 As shown, the inlet end of the fourth first tube is connected to the inlet end of the seventh second tube, with a gap of two second tubes between them.

[0050] In the second embodiment, there are at least C second tubes, which are arranged in parallel. From the second tube furthest from the heat carrier return tube towards the heat carrier return tube, they are the 1st tube, the 2nd tube...the Cth tube, where C is not less than 1.

[0051] The first tube has at least D tubes, which are arranged in parallel. From the first tube furthest from the heat carrier return tube towards the heat carrier return tube, they are the 1st tube, the 2nd tube... the Dth tube, where D is not less than 1.

[0052] The heat transfer fluid supply pipe is a two-branch pipe, with the two branch pipes being the first branch pipe and the second branch pipe, respectively.

[0053] The first branch pipe is connected to the inlet end of the first second pipe;

[0054] The outlet end of the first second pipe is connected to the inlet end of the second second pipe;

[0055] The outlet end of the second pipe is connected to the inlet end of the third pipe;

[0056] …

[0057] The outlet end of the (C-1)th second pipe is connected to the inlet end of the Cth second pipe;

[0058] The outlet end of the second pipe of the Cth branch is connected to the heat transfer fluid return pipe;

[0059] The second branch pipe is connected to the inlet end of the first pipe;

[0060] The outlet end of the first pipe is connected to the inlet end of the second pipe.

[0061] The outlet end of the second first pipe is connected to the inlet end of the third first pipe;

[0062] …

[0063] The outlet end of the (D-1)th first pipe is connected to the inlet end of the Dth first pipe;

[0064] The outlet end of the first tube of the Dth tube is connected to the heat transfer return tube.

[0065] Similar to the first implementation method, such as Figure 5 As shown, taking a heat carrier supply pipe that splits into two branches (two-way flow) as an example, the two branches are connected in parallel, allowing the heat carrier in each branch to flow back and forth between the first and second branches. Then, it is only necessary to ensure that the two branches are connected at the heat carrier return pipe. This achieves a one-to-two parallel loop, allowing the heat carrier to flow through both the finned layer and the radiant heat sink, thereby distributing heat to different locations and achieving uniform heat dissipation.

[0066] In the third embodiment, the second tube is at least E tubes, and they are arranged in parallel. From the second tube furthest from the heat carrier return tube towards the heat carrier return tube, they are the 1st tube, the 2nd tube... the Eth tube, where E is not less than 1.

[0067] The first tube has at least F tubes, which are arranged in parallel. From the first tube furthest from the heat carrier return tube towards the heat carrier return tube, they are the 1st tube, the 2nd tube... the Fth tube, where F is not less than 1.

[0068] The heat transfer fluid supply pipe is a single pipe;

[0069] The heat transfer fluid supply pipe is connected to the inlet end of the first and second pipes;

[0070] The outlet end of the first second pipe is connected to the inlet end of the second second pipe;

[0075] The outlet end of the first pipe is connected to the inlet end of the second pipe.

[0076] The outlet end of the second first pipe is connected to the inlet end of the third first pipe;

[0077] …

[0078] The outlet end of the F-1th first pipe is connected to the inlet end of the Fth first pipe;

[0079] The outlet end of the first tube of the Fth tube is connected to the heat transfer return tube.
