Description

Technical Field

[0001] The present application belongs to the technical field of air conditioning, and in particular, relates to an air conditioning evaporator and an air conditioner. Background Art

[0002] The evaporator is mainly used in air conditioning. The refrigerant (refrigerant) flows through the evaporator and is used to exchange heat with the indoor air to achieve a cooling effect. At present, the evaporator is usually set so that the refrigerant flows in from one inlet and flows out along the outlet. The inlet and outlet are set on different sides. From the inflow to the outflow direction, the refrigerant temperature gradually increases, and the cooling effect of the evaporator gradually weakens, which easily leads to the air temperature near the inlet side being too low and the air temperature near the outlet side being too high, which ultimately makes the air outlet temperature of the air conditioner uneven.

[0003] In view of this, it is necessary to provide a new type of air conditioner evaporator and air conditioner to solve the problems of low air temperature on one side of the evaporator and uneven air outlet temperature of the air conditioner caused by the evaporator structure in the prior art. Utility Model Content

[0004] In order to solve the problems of low air temperature on one side of the evaporator and uneven air outlet temperature of the air conditioner caused by the evaporator structure in the prior art, the utility model provides an air conditioner evaporator and an air conditioner. According to the first aspect of the utility model, the utility model provides an air conditioner evaporator, specifically comprising:

[0005] A first evaporation core, the first evaporation core comprising a first flow channel area and a second flow channel area;

[0006] a second evaporation core, the second evaporation core comprising a third flow channel area and a fourth flow channel area;

[0012] In one embodiment, the first evaporator core includes a first header and a second header, the inlet pipe is connected to the first header, and the flat tube is connected between the first header and the second header.

[0013] In one embodiment, the second evaporation core includes a third header and a fourth header, the outlet pipe is connected to the third header, and the flat tube is connected between the third header and the fourth header.

[0014] In one embodiment, the first current collecting pipe and the third current collecting pipe are connected to each other, the first current collecting pipe is provided with a first partition plate, and the third current collecting pipe is provided with a third partition plate.

[0015] In one embodiment, the second current collecting pipe is provided with a second partition plate, and the second partition plate is provided with a through hole; the fourth current collecting pipe is provided with a fourth partition plate, and the fourth partition plate is provided with a through hole.

[0016] In one embodiment, the first evaporation core includes a first header and a second header, the inlet pipe is connected to the second header, and the flat tube is connected between the first header and the second header; the second evaporation core includes a third header and a fourth header, the outlet pipe is connected to the fourth header, and the flat tube is connected between the third header and the fourth header.

[0018] According to a second aspect of the utility model, the utility model further provides an air conditioner, comprising any one of the above-mentioned air conditioner evaporators.

[0019] According to the solution provided by the utility model, the problem of low temperature on one side of the evaporator and uneven temperature at the air outlet of the air conditioner is solved by dividing the evaporation core into flow channel areas and setting the flow direction of the refrigerant. Specifically, the two evaporation cores are divided into four flow channel areas, namely the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area. The first flow channel area and the fourth flow channel area are aligned in the air flow direction, and the second flow channel area and the third flow channel area are also connected in the air flow direction. The refrigerant flows in from the first flow channel area, and flows through the second flow channel area and the third flow channel area in turn, and finally flows out from the fourth flow channel area. With this arrangement, the refrigerant temperature in the first flow channel area is the lowest, the refrigerant temperatures in the second and third flow channel areas are similar, and the refrigerant temperature in the fourth flow channel area is the highest. Because the first flow channel area and the fourth flow channel area are aligned in the air flow direction, the temperature of the air will not be too low or too high after passing through the first and fourth flow channel areas. Similarly, the temperature of the air will not be too low or too high after passing through the second and third flow channel areas where the refrigerant temperatures are similar, and the temperature difference with the air passing through the first and fourth flow channel areas will not be too large, so that the temperature of the air flowing through the evaporator, that is, the temperature of the air after heat exchange, is relatively uniform, and the temperature of the air outlet of the air conditioner will also be more uniform.

[0020] The air conditioner provided by the utility model also has the above advantages because it includes the above air conditioner evaporator. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Reference Figures 1 to 4 According to a first aspect of the utility model, the utility model provides an air-conditioning evaporator, comprising:

[0038] A first evaporation core, the first evaporation core comprising a first flow channel area and a second flow channel area;

[0039] A second evaporation core, wherein the second evaporation core comprises a third flow channel area and a fourth flow channel area;

[0040] an inlet pipe, the inlet pipe is used for the refrigerant to flow in and is connected to the first evaporation core;

[0041] An outlet pipe, the outlet pipe is used for the refrigerant to flow out and is connected to the second evaporation core;

[0042] The first flow channel area is aligned with the fourth flow channel area in the air circulation direction, the second flow channel area is aligned with the third flow channel area in the air circulation direction, the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area are interconnected, and the refrigerant flows through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area in sequence.

[0043] According to the exemplary solution provided by the utility model, the air conditioner evaporator includes two evaporation cores, which are usually of the same size and aligned, and are fixedly connected to each other; in addition, the two evaporation cores each include two flow channel areas, which refer to the area where the refrigerant circulates and is also the area where the refrigerant exchanges heat with the air. The air conditioner evaporator also includes an inlet pipe and an outlet pipe for the refrigerant to flow in and out, the inlet pipe is connected to the first evaporation core, and the outlet pipe is connected to the second evaporation core. After the refrigerant enters the evaporator, it first enters the first evaporation core, then enters the second evaporation core and flows out from the second evaporation core along the outlet pipe; specifically, after the refrigerant enters the evaporator, it first flows into the first flow channel area, then flows through the second flow channel area and the third flow channel area in sequence, and finally flows into the fourth flow channel area.

[0044] It can be understood that the first evaporation core body is interconnected with the second evaporation core body, and the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area are also interconnected, so that the refrigerant can flow normally in the four flow channel areas. After the refrigerant flows into the evaporator, it begins to exchange heat with the air. After the heat exchange, the temperature of the refrigerant rises. Therefore, the temperature of the refrigerant is the lowest when it just flows into the evaporator, that is, the temperature of the first flow channel area is the lowest, the temperature of the second flow channel area is lower than the third flow channel area, and the temperature of the fourth flow channel area is the highest. Further, the first flow channel area is aligned with the fourth flow channel area, and the second flow channel area is aligned with the third flow channel area. The alignment setting refers to the alignment setting in the air circulation direction. After the alignment setting, the air flowing through the first flow channel area will continue to flow in the fourth flow channel area, and the air flowing through the second flow channel area will continue to flow in the third flow channel area. Through the above setting, the temperature difference between the air flowing through the first flow channel area and the fourth flow channel area and the air flowing through the second flow channel area and the third flow channel area can be made smaller, so that the overall temperature of the air flowing through the evaporator is more uniform. Furthermore, in order to make the temperature difference between the air flowing through the first flow channel area and the fourth flow channel area and the air flowing through the second flow channel area and the third flow channel area smaller, it is preferred to set the areas of the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area to be the same.

[0045] Please refer to Figure 2 In one embodiment, each of the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area is provided with at least one flat tube, and the flat tube is used for the circulation of the refrigerant.

[0046] It can be understood that the flow channel area is composed of flat tubes. In order to improve the heat exchange uniformity of the evaporator, it is preferred to set the flat tube structure and size of the four flow channel areas to be the same; in addition, the area of ​​the flow channel area is related to the number of flat tubes. The number of flat tubes in each flow channel area is at least 1. The more flat tubes there are, the larger the area of ​​the flow channel area. Different flat tubes are arranged in parallel and spaced apart. The intervals between the flat tubes can be used for air circulation, which facilitates the heat exchange between the air and the evaporator core. The flat tubes in the same flow channel area can be arranged to be interconnected as needed. For example, different flat tubes in the same flow channel area are arranged to be head-to-tail connected, that is, one end of a flat tube is connected to another flat tube, and the other end is connected to the third flat tube. In this way, after the refrigerant flows into the flat tubes, it will flow through different flat tubes in sequence according to the connection order of the flat tubes. Of course, the flat tubes in the same flow channel area can also be arranged to be disconnected. For example, the flat tubes in the same flow channel area are arranged in parallel and spaced apart and are not connected to each other. A collecting pipe is provided, and the flat tubes in the same flow channel area are all connected to the collecting pipe. The refrigerant first flows into the collecting pipe, and then flows from the collecting pipe into different flat tubes.

[0047] It is understandable that different flow channel areas must be interconnected so that the refrigerant can flow normally through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area. Specifically, different flow channel areas can be set to be directly connected or indirectly connected. For example, it is set to be directly connected, that is, the flat tubes of different flow channel areas are directly connected, so that the refrigerant can flow from the flat tubes into the flat tubes of different flow channel areas. Of course, different flow channel areas can also be set to be indirectly connected. For example, a collecting pipe is set, and different flow channel areas are connected to the collecting pipe. After the refrigerant in the flow channel area flows out of the flat tube, it first enters the collecting pipe, and then flows from the collecting pipe into another flow channel area, and the different flow channel areas are indirectly connected with the help of the collecting pipe.

[0048] Please refer to Figures 1 to 3 In one embodiment, the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area are provided with the same number of flat tubes.

[0049] The above embodiment has explained that the flow channel area is mainly composed of flat tubes, so the area of ​​the flow channel area is determined by the number of flat tubes. In order to further reduce the temperature difference between the air flowing through the first flow channel area and the fourth flow channel area and the air flowing through the second flow channel area and the third flow channel area, it is preferred to set the areas of the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area to be the same, that is, the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area are provided with the same number of flat tubes.

[0050] Please refer to Figures 1 to 4 In one embodiment, the first evaporation core includes a first header and a second header, the inlet pipe is connected to the first header, and the flat tube is connected between the first header and the second header.

[0051] The first header and the second header are respectively arranged at the two ends of the first evaporation core, and the first header and the second header are connected by a flat tube, and the inlet tube is connected to the first header, so the refrigerant flows into the first header first after passing through the inlet tube, and then flows into the second header through the flat tube. It can be understood that the inlet tube is connected to the first header, so the refrigerant enters the first header first, so that the refrigerant can flow normally from the first header into the first flow channel area, the flat tubes of the first flow channel area are connected to the first header and the second header, and the refrigerant can flow from the flat tubes of the first flow channel area into the second header, and the flat tubes of the second flow channel area are connected to the second header, so that the refrigerant can flow normally from the second header into the second flow channel area. Regarding the connection method between the flat tubes of the second flow channel area and the first header, it can be set as needed, where the main consideration is that the refrigerant can flow normally through the first flow channel area and the second flow channel area in sequence, and enter the third flow channel area from the second flow channel area. For example, the flat tubes in the second flow channel area are not connected to the first collecting pipe, but are directly connected to the flat tubes in the third flow channel area; or, the flat tubes in the second flow channel area are directly connected to the first collecting pipe, and the second flow channel area and the third flow channel area are indirectly connected through the first collecting pipe, and a partition is arranged in the first collecting pipe to block the circulation of the refrigerant in the first collecting pipe, thereby preventing the refrigerant from directly entering the second flow channel area after entering the first collecting pipe from the inlet pipe.

[0052] Preferably, in order to allow the refrigerant to flow normally through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area in sequence after flowing into the evaporator core from the inlet pipe, the refrigerant inlet pipe is arranged at one end of the first collecting pipe close to the first flow channel area.

[0053] In summary, through the above exemplary embodiments, the refrigerant can flow normally through the first flow channel area, the second flow channel area and the third flow channel area in sequence after entering the evaporator.

[0054] Regarding the specific structural arrangement of the first header and the second header, in order to further improve the circulation and heat exchange efficiency of the refrigerant, it is preferred that the inner diameter, length and shape of the first header and the second header be the same.

[0055] Please refer to Figures 1 to 4 In one embodiment, the second evaporation core includes a third header and a fourth header, the outlet pipe is connected to the third header, and the flat tube is connected between the third header and the fourth header.

[0056] The manifold is mainly used to support the circulation of refrigerant, especially when the refrigerant is switched from one flow channel area to another, the manifold is needed to provide transition support, that is, after the refrigerant flows out from one flow channel area, it first enters the manifold, and then is diverted from the manifold to another flow channel area.

[0057] It can be understood that, since the outlet pipe is connected to the third collecting pipe, the flat tubes of the fourth flow channel area are connected to the third collecting pipe, so that the refrigerant can flow normally from the fourth flow channel area into the third collecting pipe and flow out from the outlet pipe; in order to allow the refrigerant to flow normally from the second flow channel area into the third flow channel area, the second flow channel area is connected to the third flow channel area. Specifically, the flat tubes of the second flow channel area can be directly connected to the flat tubes of the third flow channel area, or the second flow channel area is connected to the first collecting pipe, the first collecting pipe is connected to the third collecting pipe, and the flat tubes of the third flow channel area are connected to the third collecting pipe, so as to indirectly connect the second flow channel area with the third flow channel area. In order to prevent the refrigerant from flowing directly from the outlet pipe after entering the third collecting pipe, a partition can be set in the third collecting pipe to block the refrigerant from flowing in the third collecting pipe, so that the refrigerant can only flow into the flat tubes of the third flow channel area after entering the third collecting pipe.

[0058] It is understandable that in order to allow the refrigerant to flow normally from the third flow channel area to the fourth flow channel area in sequence, the third flow channel area is directly connected to the fourth flow channel area or indirectly connected to the fourth flow channel area. For example, the flat tubes of the third flow channel area are directly connected to the flat tubes of the fourth flow channel area; or, the flat tubes of the third flow channel area are connected to the fourth header, and the fourth header is connected to the flat tubes of the fourth flow channel area, and the third flow channel area and the fourth flow channel area are indirectly connected by means of the fourth header.

[0059] Preferably, in order to allow the refrigerant to flow normally through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area in sequence, the refrigerant outlet pipe is arranged at one end of the third manifold close to the fourth flow channel area.

[0060] Regarding the setting of the inlet pipe and the outlet pipe, the uniformity of the heat exchange of the evaporator is mainly considered. As long as the refrigerant can flow normally through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area in sequence, it can be set as needed to which specific header it is connected to. For example, the inlet pipe can also be connected to the second header, and the outlet pipe can also be set to be connected to the fourth header. In addition, it is only necessary to simultaneously set a through hole on the first partition of the first header, connect the second header with the fourth header through the flow channel, and set a through hole on the third partition of the third header, so that the refrigerant can flow normally through the four flow channel areas in sequence, which can also improve the problem of uniformity of overall heat exchange of the evaporator.

[0061] Please refer to Figures 1 to 4 In one embodiment, the first current collecting pipe and the third current collecting pipe are interconnected, the first current collecting pipe is provided with a first partition plate, and the third current collecting pipe is provided with a third partition plate.

[0062] The partition is arranged in the inner cavity of the manifold, and mainly plays the role of flow blocking, that is, when the refrigerant flows into the manifold from the flat tube, the partition arranged in the manifold can prevent the refrigerant from flowing in a certain direction in the manifold. Of course, the partition can also be provided with a through hole, and the through hole allows the refrigerant to continue to flow through the through hole. Alternatively, a partition is provided for the manifold that needs to be blocked, and no partition is provided for the manifold that does not need to be blocked. For example, according to the above embodiment, it can be known that the first manifold needs to be blocked, and the second manifold does not need to be blocked, so the first manifold can be provided with a partition, and the second manifold can be provided with a partition.

[0063] The third manifold is provided with a third partition. The third partition mainly plays a flow blocking role for the third manifold, especially when the refrigerant enters the second evaporation core from the first evaporation core, that is, enters the third manifold from the first manifold, with the help of the flow blocking effect of the third partition, the refrigerant will not flow directly into the outlet pipe from the third manifold, but into the third flow channel area. The specific structural setting of the third partition can refer to the first partition, and will not be repeated here.

[0064] It should be noted that the position where the first manifold is connected to the third manifold is between the second flow channel area and the third flow channel area, so that the refrigerant will not flow directly into the third manifold after entering the first manifold. It can be understood that both the first manifold and the third manifold are provided with partitions, so after the refrigerant flows into the first manifold, it can normally flow into the first flow channel area first and then into the second flow channel area; the first manifold and the third manifold are connected to each other, so the refrigerant enters from the second flow channel area and flows into the first manifold again, and can flow into the third manifold from the connecting position. The third manifold is provided with a partition, so after the refrigerant flows into the third manifold, it will not flow directly from the third manifold into the outlet pipe, and can flow normally into the third flow channel area and the fourth flow channel area, and finally flow out from the fourth flow channel area.

[0065] Please refer to Figures 1 to 4 In one embodiment, the second current collecting pipe is provided with a second partition plate, and the second partition plate is provided with a through hole; the fourth current collecting pipe is provided with a fourth partition plate, and the fourth partition plate is provided with a through hole.

[0066] The above embodiment has explained that the second manifold and the fourth manifold can be provided with partitions as needed, which mainly considers the normal circulation of the refrigerant in the second manifold and the fourth manifold, so the second partition and the fourth partition are both provided with through holes, and the through holes allow the refrigerant to pass through and circulate normally. Further, in order to reduce the difference in the flow rate and flow velocity of the refrigerant passing through the through holes of the second partition and the fourth partition per unit time, so that the overall heat exchange of the evaporator is more uniform, it is preferred to set the through holes of the second partition and the fourth partition to be the same size.

[0067] Please refer to Figure 5In one embodiment, the first evaporation core includes a first header and a second header, the inlet pipe is connected to the second header, and the flat tube is connected between the first header and the second header; the second evaporation core includes a third header and a fourth header, the outlet pipe is connected to the fourth header, and the flat tube is connected between the third header and the fourth header.

[0068] This embodiment is another implementation method for setting the outlet pipe and the inlet pipe, which is different from the above embodiment. In this embodiment, the inlet pipe is connected to the second header, and the outlet pipe is connected to the fourth header. Furthermore, the first header is connected to the second header through flat tubes, and the third header is connected to the fourth header through flat tubes to ensure the normal flow direction of the refrigerant. Specifically, after the above scheme is implemented, the refrigerant will first enter the second header, and the flat tubes of the first flow channel area are connected between the first header and the second header, so that the refrigerant can flow normally from the second header into the first header, and the flat tubes of the second flow channel area are connected to the first header, so that the refrigerant can flow from the first header into the second flow channel area. As for whether the flat tubes of the second flow channel area are connected to the second header, it can be set as needed, mainly considering that the refrigerant can flow normally from the second flow channel area to the third flow channel area. The specific implementation method has been described in the above embodiment and will not be repeated.

[0069] Preferably, in order to allow the refrigerant to flow normally through the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area in sequence after flowing into the evaporator core from the inlet pipe, the refrigerant inlet pipe is arranged at one end of the second collecting pipe close to the first flow channel area, and the refrigerant outlet pipe is arranged at one end of the fourth collecting pipe close to the fourth flow channel area.

[0070] Please refer to Figure 5 In one embodiment, the second collecting pipe is connected to the fourth collecting pipe, and the second collecting pipe is provided with a fifth partition plate; the fourth collecting pipe is provided with a sixth partition plate.

[0071] It is understandable that the second header and the fourth header are interconnected so that the refrigerant can flow from the second header into the fourth header, that is, the refrigerant flows from the second flow channel area into the second header, and from the fourth header into the third flow channel area. It should be noted that the connection position between the second header and the fourth header is in the second flow channel area and the third flow channel area, and the second header is provided with a fifth baffle, which can play a blocking role, so that the refrigerant will not flow directly into the fourth header after flowing into the second header. Similarly, the fourth header is provided with a sixth baffle, so that the refrigerant will not flow directly into the outlet pipe after entering the fourth header. The connection relationship between the flat tubes of the first flow channel area, the second flow channel area, the third flow channel area and the fourth flow channel area and the first header, the second header, the third header and the fourth header can be set as needed. The above embodiments have been described in detail and will not be repeated.

[0072] Please refer to Figures 1 to 5 According to the second aspect of the utility model, the utility model also provides an air conditioner, which includes any of the above-mentioned air conditioner evaporators, so the air conditioner also has the above-mentioned advantages.

[0073] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
