Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange systems, and in particular to a heat exchanger, a heat exchange system and an air conditioner. Background Art

[0002] When the air conditioner heat exchanger is exchanging heat, there is a phase change in the pipeline. In order to achieve a better heat exchange effect, one main pipeline will be divided into multiple pipelines or multiple pipelines will be merged into one pipeline. In this way, the refrigerant fluid speed in the pipeline is relatively stable, thereby improving the surface heat transfer coefficient between the refrigerant and the pipe wall, and improving the heat exchange capacity under the condition of unchanged heat exchange area. For double-row or multi-row heat exchanger diversion, the front and rear row positions and air volume of the two or more pipelines cannot be exactly the same. In actual tests, it was found through thermocouples on each pipeline that the temperature difference between the cold and the medium of the two or more pipelines is large, the heat exchange is uneven, and the overall heat exchange effect of the heat exchanger is affected. At present, the heat exchange effect of the air conditioner heat exchanger is poor due to heat accumulation in the pipeline during operation, which affects the user's use effect and comfort.

[0003] There is no effective solution to the above problems yet. Utility Model Content

[0039] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0040] Combination Figure 1 to Figure 2As shown, according to a specific embodiment of the utility model, a heat exchanger is provided. Specifically, a heat exchanger body 100 is provided with a plurality of heat exchange channels for heat exchange medium to pass through; a first heat exchange channel 12 is connected with part of the heat exchange channels among the plurality of heat exchange channels, and the first heat exchange channel 12 has a first inlet 121; a second heat exchange channel 22 is connected with another part of the heat exchange channels among the plurality of heat exchange channels, and the second heat exchange channel 22 has a second inlet 221; the flow direction of the heat exchange medium in the first heat exchange channel 12 and the flow direction of the heat exchange medium in the second heat exchange channel 22 have an angle, wherein 0°<angle≤180°, such a setting prevents heat accumulation in adjacent first heat exchange channels 12 and second heat exchange channels 22 when the flow directions of the first heat exchange channel 12 and the second heat exchange channel 22 are the same, thereby enhancing the heat exchange effect.

[0041] It should be noted that the flow direction of the heat exchange medium in the first heat exchange path 12 and the flow direction of the heat exchange medium in the second heat exchange path 22 have an angle, which means that the flow direction of the heat exchange medium in the first heat exchange path 12 is different from the flow direction of the heat exchange medium in the second heat exchange path 22. If the flow trajectory of the heat exchange medium in the first heat exchange path 12 and the second heat exchange path 22 is projected onto the end surface of the heat exchanger body 100, the trajectory profiles of the first heat exchange path 12 and the second heat exchange path 22 are composed of multiple zigzag segments formed on the heat exchanger body 100, and at the corresponding zigzag segments in the first heat exchange path 12 and the second heat exchange path 22 (for example, zigzag segments with the same stroke, with the first inlet 121 of the first heat exchange path 12 as the starting point and the second inlet 221 of the second heat exchange path 22 as the starting point), the flow direction of the heat exchange medium here is different.

[0042] Furthermore, the flow direction of the heat exchange medium in the first heat exchange flow path 12 is opposite to the flow direction of the heat exchange medium in the second heat exchange flow path 22. This arrangement avoids heat accumulation in the first heat exchange flow path 12 and the second heat exchange flow path 22, and reduces the temperature difference between various parts of the heat exchanger.

[0043] Further, the first inlet 121 and the second inlet 221 are arranged in the middle of the heat exchanger body 100, wherein it should be noted that the area between the top and the bottom of the heat exchanger body 100 is referred to as the middle of the heat exchanger body 100, and such an arrangement further optimizes the effect of reducing the temperature difference. In a preferred embodiment of the present application, the first inlet 121 and the second inlet 221 are both arranged at one-half of the height direction of the heat exchanger body 100.

[0044] Furthermore, the first inlet 121 and the second inlet 221 are arranged on the same side of the heat exchanger body 100, or the first inlet 121 and the second inlet 221 are arranged on opposite side walls of the heat exchanger body 100, which further optimizes the effect of reducing the temperature difference.

[0045] Furthermore, the first flow outlet 122 and the second flow outlet 222 are arranged in the middle of the heat exchanger body 100, and such an arrangement further optimizes the effect of reducing the temperature difference.

[0046] Furthermore, the first heat exchange flow path 12 has a first flow outlet 122, and the second heat exchange flow path 22 has a second flow outlet 222. The first flow outlet 122 and the second flow outlet 222 are arranged on the same side of the heat exchanger body 100, or the first flow outlet 122 and the second flow outlet 222 are arranged on opposite sides of the heat exchanger body 100.

[0047] Furthermore, the first flow outlet 122 and the second flow outlet 222 are arranged in the middle of the heat exchanger body 100. This arrangement makes the fluid velocity of the heat exchange medium in the first heat exchange flow path 12 and the second heat exchange flow path 22 relatively stable, thereby improving the surface heat transfer coefficient between the heat exchange medium and the tube wall, and improving the heat exchange capacity and enhancing the reliability of the heat exchanger when the heat exchange area remains unchanged.

[0048] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present application, after the heat exchange medium in the first heat exchange flow path 12 flows in from the first inlet 121, it flows from the middle to the top in the height direction of the heat exchanger body 100, then flows from the top to the bottom of the heat exchanger body 100, flows through the bottom of the heat exchanger body 100 to the middle, and finally flows out through the first outlet 122. After the heat exchange medium in the second heat exchange flow path 22 flows in from the second inlet 221, it flows from the middle to the bottom in the height direction of the heat exchanger body 100, then flows from the bottom to the top of the heat exchanger body 100, finally flows through the top of the heat exchanger body 100 to the middle, and finally flows out through the second outlet 222. This arrangement prevents heat accumulation in the heat exchange flow channel, avoids temperature differences caused by different wind forces and wind speeds blowing through various parts of the heat exchanger, makes heat exchange more uniform, and improves the overall heat exchange effect of the heat exchanger.

[0049] Furthermore, the heat exchanger includes: a collecting U-shaped tube 41, a collecting port 411 is provided at the bend of the collecting U-shaped tube 41, and the first flow outlet 122 of the first heat exchange flow path 12 and the second flow outlet 222 of the second heat exchange flow path 22 are respectively connected to the collecting U-shaped tube 41, so that the heat exchange medium discharged from the first heat exchange flow path and the second heat exchange flow path 22 can be discharged from the heat exchanger body 100 through the collecting port 411.

[0050] Combination Figure 1 to Figure 2As shown, in this embodiment, the heat exchanger includes a collecting U-shaped tube 41, and a collecting port 411 is provided at the bend of the collecting U-shaped tube 41. The first outlet 122 of the first heat exchange flow path 12 and the second outlet 222 of the second heat exchange flow path 22 are respectively connected to the collecting U-shaped tube 41, so that the heat exchange medium discharged from the first heat exchange flow path 12 and the second heat exchange flow path 22 is discharged from the heat exchanger body 100 through the collecting port 411. This arrangement makes the fluid velocity of the heat exchange medium in the first heat exchange flow path 12 and the second heat exchange flow path 22 relatively stable, thereby improving the surface heat transfer coefficient between the heat exchange medium and the tube wall, and improving the heat exchange capacity and enhancing the reliability of the heat exchanger when the heat exchange area remains unchanged. In addition, this arrangement helps to optimize the pipe structure of the heat exchanger, making the spatial layout of the heat exchanger more reasonable.

[0051] Furthermore, along the thickness direction of the heat exchanger body 100 , at least a portion of the first heat exchange flow path 12 and a portion of the second heat exchange flow path 22 are arranged side by side.

[0052] Combination Figure 1 and Figure 2 As shown, in this embodiment, at least one heat exchange channel located at the top of the heat exchanger body 100 and at least one heat exchange channel located at the bottom of the heat exchanger body 100 form part of the first heat exchange flow path 12 and the second heat exchange flow path 22, and along the thickness direction of the heat exchanger body 100, at least part of the first heat exchange flow path 12 and part of the second heat exchange flow path 22 are arranged side by side. This arrangement improves the heat exchange efficiency of the first heat exchange flow path 12 and the second heat exchange flow path 22, and increases the practicality of the heat exchanger.

In this embodiment, the preset direction is the length direction of the heat exchanger body. This arrangement optimizes the heat exchange effect of the first heat exchange path 12 and the second heat exchange path 22, and achieves more uniform heat exchange.

[0054] Furthermore, the plurality of heat exchange channels are extended along the length direction of the heat exchanger body 100 , and the plurality of heat exchange channels are spaced apart along the thickness direction and the height direction of the heat exchanger body 100 .

[0055] Combination Figure 1As shown, at least one heat exchange channel located at the top of the heat exchanger body 100 and at least one heat exchange channel located at the bottom of the heat exchanger body 100 form part of the first heat exchange channel 12 and the second heat exchange channel 22.

This arrangement can reduce the temperature difference of the heat exchange channel, avoid the accumulation of heat exchange medium at the bottom, make the heat exchange more uniform, and optimize the heat exchange effect.
