Description
Technical Field
[0001] The present application relates to the technical field of air conditioning, and in particular to a heat exchanger and an air conditioner. Background Art
[0002] When the existing heat exchanger is used as an evaporator, a large amount of water droplets are easily condensed on the fins and heat exchange tubes to produce condensation, and the condensation cannot be discharged in time, which will increase the wind resistance of the heat exchanger and attenuate the air volume.
[0003] To this end, the relevant technology provides a fin for a heat exchanger, a heat exchanger and an air conditioner, the heat exchanger includes a plurality of flat tubes, the fin device includes a guide assembly, a connecting member and a plurality of fin bodies extending horizontally from the windward end of the connecting member, an installation space is formed between two adjacent fin bodies, and each flat tube is respectively installed in the installation space corresponding thereto; the guide assembly is arranged on the connecting member and each fin body, and the guide assembly is used to drain the condensed water on the fin body and the flat tube.
[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] The condensed water flowing from the fins and the flat tubes into the guide member located on the fin body flows out under the combined action of surface tension and wind force, with a slow flow speed and poor drainage effect.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content
[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.
[0008] The embodiments of the present disclosure provide a heat exchanger and an air conditioner to solve the problem in the related art that condensed water flowing into a guide component located on a fin body has a slow flow speed and poor drainage effect.
[0009] According to the first aspect of the embodiment of the utility model, a heat exchanger is provided, comprising: a heat exchange tube; a plurality of fins, wherein the plurality of fins are arranged in sequence along the length direction of the heat exchange tube, the fin comprising a fin body, the fin body being provided with a mounting groove, and the heat exchange tube passing through the mounting groove; wherein the fin body is provided with a guide portion connected thereto, the guide portion being arranged at an angle for discharging condensed water on the fin body.
[0010] The condensed water generated on the fin body flows into the guide part. Since the guide part is set inclined, the condensed water flowing into the guide part not only flows under the action of surface tension and wind, but also flows under the action of its own gravity, thereby increasing the flow speed of the condensed water and improving the drainage effect of the guide part.
[0011] In some embodiments, the angle between the guide portion and the horizontal direction ranges from 1° to 10°.
[0012] When the angle between the guide part and the horizontal direction is less than 1°, the inclination of the guide part will be too small. When the condensed water flows in the guide part, the gravity of the condensed water has a small effect on the flow, and the flow speed of the condensed water in the guide part is still small; when the angle between the guide part and the horizontal direction is greater than 10°, the inclination of the guide part will be too large, which will greatly affect the ratio of the area occupied by the fins and the heat exchange tubes on the heat exchanger. Specifically, it will reduce the area ratio of the fins and affect the heat exchange performance of the heat exchanger.
[0013] In some embodiments, the air guide portion is inclined downward along a direction from a windward end to a leeward end of the heat exchanger.
[0014] In this way, the force of wind passing through the heat exchanger has the same effect as gravity on the flow of condensed water in the guide part, both of which accelerate the flow of condensed water. Therefore, the inclination of the guide part is beneficial to the flow of condensed water in the guide part and increases the speed of the condensed water draining the guide part.
[0015] In some embodiments, the fin further includes: a water pouring portion, which is connected to the fin body and the water pouring portion and the fin body are arranged in sequence along the direction from the leeward end to the windward end, and a water guiding structure connected to the guide portion is provided, and the guide portion extends in the direction from the fin body to the water pouring portion so that the condensed water in the guide portion flows to the water guiding structure.
[0016] The condensed water flows in the guide part from the windward end to the leeward end, and the fin body and the water pouring part flow from the windward end to the leeward end, and the guide part is inclined downward from the windward end to the leeward end of the heat exchanger. In this way, under the action of wind and its own gravity, the condensed water in the guide part flows toward the water guide structure and flows out of the heat exchanger through the water guide structure.
[0017] In some embodiments, the guide portion is disposed on the top wall of the installation groove, and the upper surface of the heat exchange tube is inclined and the inclination direction is the same as the inclination direction of the guide portion.
[0018] The upper surface of the heat exchange tube is inclined and the inclination direction is the same as the inclination direction of the guide part to ensure that the heat exchange tube has a sufficiently large contact area with the fins to ensure the heat exchange capacity of the heat exchanger.
[0019] In some embodiments, the lower surface of the heat exchange tube is horizontally or inclined.
[0020] When the lower surface of the heat exchange tube is horizontally arranged, the bottom wall of the installation groove is also a horizontal plane to ensure the contact area between the lower surface of the heat exchange tube and the bottom wall of the installation groove. Both are horizontal planes, which can reduce the difficulty of forming the heat exchange tube and the fin.
[0021] When the lower surface of the heat exchange tube is inclined, the condensed water on the heat exchange tube can quickly gather at the lowest point on the lower surface of the heat exchange tube. Under the combined effects of wind force, surface tension and the gravity of the condensed water, the condensed water quickly flows out of the guide part.
[0022] In some embodiments, the flow area of the heat exchange tube decreases along the direction from the air inlet end to the air outlet end.
[0023] Along the direction from the air inlet end to the air outlet end, the flow area of the heat exchange tube decreases, that is, the volume of the heat exchange tube decreases, and the amount of refrigerant contained in the heat exchange tube also decreases. The amount of refrigerant in the heat exchange tube can match the temperature difference between the windward end and the leeward end. Therefore, the change in the volume of the heat exchange tube is consistent with the changing trend of the cooling amount required for the heat exchange process, making the refrigerant heat exchange more balanced and improving the overall heat exchange efficiency and heat exchange capacity of the heat exchanger.
[0024] In some embodiments, a microchannel is provided in the heat exchange tube, and the height of the microchannel decreases along the direction from the air inlet end to the air outlet end.
[0025] This arrangement can conveniently reduce the flow area of the heat exchange tube in the direction from the air inlet end to the air outlet end, and can also easily realize the inclined arrangement of the guide part.
[0026] In some embodiments, a plurality of microchannels are disposed in the heat exchange tube, and the plurality of microchannels are sequentially arranged in a direction from the air inlet end to the air outlet end, and the height of the microchannels decreases in the direction from the air inlet end to the air outlet end.
[0027] This setting can reduce the flow area of the microchannel along the direction from the air inlet end to the air outlet end, so that the amount of refrigerant in the microchannel can match the temperature difference between the windward end and the leeward end, thereby improving the heat exchange effect of the heat exchanger.
[0028] According to a second aspect of an embodiment of the utility model, an air conditioner is provided, comprising a heat exchanger as described in any one of the above embodiments.
[0029] The air conditioner provided in the embodiment of the second aspect of the present application includes the heat exchanger as described in any one of the above embodiments, and thus has all the beneficial effects of the heat exchanger as described in any one of the above embodiments, which will not be repeated here.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0050] like Figures 1 to 4 , Figure 6 As shown, an embodiment of the first aspect of the present application provides a heat exchanger 100 for an air conditioner.
[0051] The air conditioner includes an outdoor unit and an indoor unit, and the outdoor unit and the indoor unit are connected through a connection pipe. The outdoor unit includes an outdoor heat exchanger 100, and the indoor unit includes an indoor heat exchanger 100. The heat exchanger 100 in the present application can be an indoor heat exchanger 100 or an indoor heat exchanger 100.
[0052] like Figure 3 As shown, the heat exchanger 100 includes heat exchange tubes 2 and fins 1 .
[0053] There are multiple fins 1 and the multiple fins 1 are sequentially arranged along the length direction of the heat exchange tube 2 . The fin 1 includes a fin body 11 . The fin body 11 is provided with a mounting groove 114 . The heat exchange tube 2 passes through the mounting groove 114 .
[0054] The fin body 11 is provided with a guide portion 111 in communication therewith, and the guide portion 111 is arranged obliquely to discharge condensed water on the fin body 11 .
[0055] There are multiple heat exchange tubes 2, which are arranged in sequence from top to bottom. Each fin body 11 is provided with multiple mounting grooves 114, the number of which is equal to the number of heat exchange tubes 2, and the multiple mounting grooves 114 are arranged in sequence from top to bottom, and each heat exchange tube 2 is located in a mounting groove 114.
[0056] The condensed water generated on the fin body 11 flows into the guide part 111. Since the guide part 111 is arranged at an angle, the condensed water flowing into the guide part 111 flows not only under the action of surface tension and wind, but also under the action of its own gravity, thereby increasing the flow speed of the condensed water and improving the drainage effect of the guide part 111.
[0057] Alternatively, if Figure 3 In the embodiment, the angle A between the guide portion 111 and the horizontal direction is in the range of 1°-10°.
[0058] When the angle between the guide part 111 and the horizontal direction is less than 1°, the inclination of the guide part 111 is too small. When the condensed water flows in the guide part 111, the gravity of the condensed water has a small effect on the flow, and the flow speed of the condensed water in the guide part 111 is still relatively small; when the angle between the guide part 111 and the horizontal direction is greater than 10°, the inclination of the guide part 111 is too large, which will greatly affect the ratio of the area occupied by the fin 1 and the heat exchange tube 2 on the heat exchanger 100. Specifically, it will reduce the area ratio of the fin 1 and affect the heat exchange performance of the heat exchanger 100.
[0059] The angle between the guide portion 111 and the horizontal direction can be 1°, 3°, 5°, 8° or 10°, which can not only increase the flow rate of the condensed water in the guide portion 111, but also will not affect the heat exchange performance of the heat exchanger 100.
[0060] Optionally, along the direction from the windward end 101 to the leeward end 102 of the heat exchanger 100 , the air guide 111 is inclined downward.
[0061] The direction in which the wind passes through the heat exchanger 100 is from the windward end 101 to the leeward end 102, so the condensed water in the guide portion 111 has a tendency to flow along the direction in which the wind passes through the heat exchanger 100. The guide portion 111 is inclined downward from the windward end 101 to the leeward end 102 of the heat exchanger 100. In this way, the force of the wind passing through the heat exchanger 100 and the gravity have the same effect on the flow of the condensed water in the guide portion 111, which is to accelerate the flow of the condensed water. Therefore, the inclination of the guide portion 111 is conducive to the flow of the condensed water in the guide portion 111, and increases the speed of the condensed water draining the guide portion 111.
[0062] Alternatively, if Figure 3 As shown, the fin 1 also includes a water pouring portion 12, which is connected to the fin body 11 and is arranged in sequence along the direction from the leeward end 102 to the windward end 101. The water pouring portion 12 is provided with a water guiding structure 121 connected to the guide portion 111 so that the condensed water in the guide portion 111 flows to the water guiding structure 121.
[0063] The condensed water flows in the guide portion 111 along the direction from the windward end 101 to the leeward end 102, and the fin body 11 and the water pouring portion 12 flow along the direction from the windward end 101 to the leeward end 102, and along the direction from the windward end 101 to the leeward end 102 of the heat exchanger 100, the guide portion 111 is inclined downward, so that under the action of wind force and its own gravity, the condensed water in the guide portion 111 flows toward the water guide structure 121, and flows out of the heat exchanger 100 through the water guide structure 121.
[0064] The guide portion 111 includes a guide groove 113, the opening of the guide groove 113 faces the fin body 11 where the guide groove 113 is located, so as to communicate with the fin body 11 and receive condensed water from the fin body 11 and the heat exchange tube 2. The guide groove 113 extends from the windward end 101 to the leeward end 102 of the heat exchanger 100, that is, from the fin body 11 to the guide portion 111, so as to guide the condensed water in the guide groove 113 to the water guide structure 121.
[0065] The guide groove 113 may be formed by slotting the fin body 11, or by providing a flange 112 on one side of the fin body 11 in the thickness direction. Figure 3 As shown, the flange 112 defines a guide groove 113. Providing the flange 112 can also enhance the strength of the fin body 11.
[0066] The upper end of the water pouring portion 12 is higher than or flush with the upper end of the fin body 11, and the lower end of the water pouring portion 12 is lower than or flush with the lower end of the fin body 11. The water guide structure 121 includes a water guide groove 122, which extends in the up-down direction and passes through the upper end surface and the lower end surface of the water pouring portion 12. In this way, the water guide groove 122 can be connected with all the guide grooves 113, and the condensed water in all the guide grooves 113 can flow into the water guide groove 122.
[0067] A connecting groove 13 is also provided on the water pouring portion 12 . The connecting groove 13 is connected between the guide groove 113 and the water guide groove 122 . Condensed water in the guide groove 113 flows into the water guide groove 122 through the connecting groove 13 .
[0068] Optionally, the guide portion 111 is disposed on the groove top wall 1141 of the installation groove 114, for example, the groove top wall 1141 of the installation groove 114 may be folded upward to form a flange 112, and the flange 112 defines the guide groove 113. The upper surface 21 of the heat exchange tube is inclined and the inclination direction is the same as the inclination direction of the guide portion 111.
[0069] The upper surface 21 of the heat exchange tube is inclined and the inclination direction is the same as the inclination direction of the guide portion 111 to ensure that the heat exchange tube 2 and the fin 1 have a sufficiently large contact area to ensure the heat exchange capacity of the heat exchanger 100.
[0070] like Figure 1 As shown, the angle B between the upper surface 21 of the heat exchange tube and the horizontal direction ranges from 1° to 10°, and the difference between the upper surface 21 of the heat exchange tube and the inclination angle of the guide portion 111 is less than or equal to 3°.
[0071] It is understandable that Figure 5As shown, the upper surface 21 of the heat exchange tube can also be arranged horizontally, and the guide part is also arranged horizontally. In the direction from the air inlet end to the air outlet end, the lower surface 21 of the heat exchange tube is inclined downward. When the condensed water slides to the upper surface of the heat exchange tube, under the blowing of gravity and airflow, the condensed water overcomes the effect of surface tension and flows rapidly from the windward end of the heat exchanger to the leeward end along the inclined lower surface of the heat exchange tube to be discharged. Therefore, the drainage efficiency of the heat exchanger is high, and the heat exchange wind resistance and heat transfer thermal resistance of the heat exchanger are reduced.
[0072] Optionally, the lower surface 22 of the heat exchange tube is horizontally arranged, or inclined and the inclination direction is opposite to or the same as the inclination direction of the guide portion 111 .
[0073] The lower surface 22 of the heat exchange tube, that is, the lower surface 22 of the heat exchange tube can be arranged horizontally (such as Figure 2 , Figure 4 as shown) or tilt settings (as Figure 3 , Figure 5 and Figure 6 As shown). Since the guide portion 111 is arranged on the groove top wall 1141 of the installation groove 114 where the guide portion 111 is located, that is, located above the heat exchange tube 2 in the installation groove 114, whether the lower surface 22 of the heat exchange tube is inclined will not affect the inclined setting of the guide portion 111.
[0074] Furthermore, when the lower surface 22 of the heat exchange tube is arranged horizontally, Figure 2 and Figure 4 As shown, the bottom wall 1142 of the installation groove 114 is also a horizontal plane to ensure the contact area between the lower surface 22 of the heat exchange tube and the bottom wall 1142 of the installation groove 114. Both are horizontal planes, which can reduce the difficulty of forming the heat exchange tube 2 and the fin 1.
[0075] When the lower surface 22 of the heat exchange tube is inclined, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the condensed water on the heat exchange tube 2 can quickly gather at the lowest point on the lower surface 22 of the heat exchange tube. When the inclination direction of the lower surface 22 of the heat exchange tube is opposite to the inclination direction of the guide portion 111, the lowest point on the lower surface 22 of the heat exchange tube corresponds to the highest point of the guide portion 111, so that the lowest point on the lower surface 22 of the heat exchange tube falls into the highest point of the guide portion 111. Under the action of wind force and the gravity of condensed water, the condensed water quickly flows out of the guide portion 111.
[0076] like Figure 3 As shown, the lower surface 22 of the heat exchange tube is inclined and the inclination direction is opposite to the inclination direction of the guide part 111, which means that along the direction from the windward end 101 to the leeward end 102 of the heat exchanger 100, the guide part 111 is inclined downward and the lower surface 22 of the heat exchange tube is inclined upward.
[0077] like Figure 6 As shown, the lower surface 22 of the heat exchange tube is tilted and the tilting direction is the same as the tilting direction of the air guide 111, which means that along the direction from the windward end 101 to the leeward end 102 of the heat exchanger 100, the air guide 111 tilts downward, and the lower surface 22 of the heat exchange tube tilts downward. In the direction from the air inlet end to the air outlet end, the lower surface 21 of the heat exchange tube tilts downward. When the condensed water slides to the upper surface of the heat exchange tube, under the blowing of gravity and airflow, the condensed water overcomes the effect of surface tension and flows rapidly from the windward end of the heat exchanger to the leeward end along the tilted lower surface of the heat exchange tube to be discharged. Therefore, the drainage efficiency of the heat exchanger is high, and the heat exchange wind resistance and heat transfer thermal resistance of the heat exchanger are reduced.
[0078] Optionally, the flow area of the heat exchange tube 2 decreases along the direction from the air inlet end to the air outlet end.
[0079] When liquid flows in a pipe, the cross section perpendicular to the flow direction is the flow cross section, and the area of the flow cross section is the flow area.
[0080] Along the direction from the air inlet end to the air outlet end, the flow area of the heat exchange tube 2 decreases, that is, the volume of the heat exchange tube 2 decreases, and the amount of refrigerant contained in it also decreases. The amount of refrigerant in the heat exchange tube 2 can match the temperature difference between the windward end 101 and the leeward end 102, so that the change in the volume of the heat exchange tube 2 is consistent with the change trend of the cooling amount required for the heat exchange process, making the refrigerant heat exchange more balanced and improving the overall heat exchange efficiency and heat exchange amount of the heat exchanger 100.
[0081] Alternatively, if Figure 1 and Figure 2 As shown, along the direction from the air inlet end to the air outlet end, the flow area of the heat exchange tube 2 gradually decreases.
[0082] A plurality of microchannels 23 are provided in the heat exchange tube 2, and the plurality of microchannels 23 are sequentially arranged at intervals along the direction from the air inlet end to the air outlet end. Along the direction from the air inlet end to the air outlet end, the flow area of the plurality of microchannels 23 decreases, for example, gradually decreases.
[0083] In a specific embodiment, the height of the microchannel 23 decreases along the direction from the air inlet end to the air outlet end, thereby reducing the flow area of the microchannel 23 .
[0084] Alternatively, if Figure 1 and Figure 2 As shown, along the direction from the air inlet end to the air outlet end, the height of the microchannel 23 gradually decreases.
[0085] Optionally, the height of the heat exchange tube 2 decreases along the direction from the air inlet end to the air outlet end.
[0086] This arrangement can conveniently reduce the flow area of the heat exchange tube 2 along the direction from the air inlet end to the air outlet end, and can also easily realize the inclined arrangement of the guide portion 111 .
