[0035] Figure 1 This is a schematic diagram of the three-dimensional structure of the first embodiment of the heat exchanger of the utility model. Figure 2 This is a schematic structural diagram of the first embodiment of the heat exchanger of the utility model. Figure 3 Schematic diagram of the partial structure of the first embodiment of the heat exchanger of the utility model. In the first embodiment of the heat exchanger 100 of the utility model, the heat exchanger 100 includes a plurality of fin assemblies 130, and the plurality of fin assemblies 130 are respectively arranged on the first side A1 and the second side A2, and the spacing between the fin assemblies 130 close to the air outlet is greater than the spacing between the fin assemblies 130 away from the air outlet.

[0036] In the embodiment of the utility model, both sides of the heat exchanger 100 are windward surfaces, and a plurality of fin assemblies 130 are arranged on the windward surface of the heat exchanger 100. Each fin assembly 130 includes a plurality of fins 131 arranged at intervals, and the airflow at the air outlet flows into the heat exchanger 100 through the guide of the fin assembly 130. Since the airflow at the air inlet blows toward the windward surface, the wind speed at different positions of the windward surface is different, and the closer to the air outlet, the greater the wind speed, and the farther away from the air outlet, the smaller the wind speed. In the embodiment of the utility model, the spacing between adjacent fin assemblies 130 near the air outlet is greater than the spacing between the fin assemblies 130 far away from the air outlet, so that airflows of different flow rates flow into the heat exchanger 100 evenly through the fin assembly 130.

[0037] The heat exchanger 100 of the embodiment of the utility model includes a plurality of fin assemblies 130, and the plurality of fin assemblies 130 are respectively arranged on the windward surface of the first side A1 and the second side A2 of the heat exchanger 100. By arranging the plurality of fin assemblies 130 on the windward surface at different intervals, the interval between adjacent fin assemblies 130 close to the air outlet is greater than the interval between the fin assemblies 130 far from the air outlet. When the airflow flows into the heat exchanger 100 through the windward surface of the first side A1 and the second side A2 of the heat exchanger 100, the plurality of fin assemblies 130 arranged at different intervals can uniformly guide the airflow, improve the uniformity of the airflow flowing into the heat exchanger 100 and the heat exchange efficiency of the heat exchanger 100, and reduce the wind noise of the fins 131.

[0038] In some embodiments, at least two heat exchange areas are respectively provided on the first side A1 and the second side A2, and at least two heat exchange areas are arranged one by one in the direction away from the air outlet, and the spacing between the multiple fin assemblies 130 located in the heat exchange area close to the air outlet is greater than the spacing between the multiple fin assemblies 130 located in the heat exchange area away from the air outlet.

[0039] In this embodiment, at least two heat exchange areas are sequentially arranged on the windward surfaces of the first side A1 and the second side A2 of the heat exchanger 100 from the side close to the air outlet to the side far from the air outlet. Since the wind speed of the heat exchange area close to the air outlet is relatively high, and the wind speed of the heat exchange area far from the air outlet is relatively low, the spacing between the multiple fin assemblies 130 in the heat exchange area close to the air outlet is greater than the spacing between the multiple fin assemblies 130 in the heat exchange area far from the air outlet, so that the airflow of the air outlet can flow into the heat exchanger 100 evenly from the windward surfaces at different positions of the first side A1 and the second side A2.

[0040] Figure 4 The utility model heat exchanger 100 Figure 3 The enlarged schematic diagram of point B in the middle, Figure 5 The utility model heat exchanger 100 Figure 3 Enlarged schematic diagram of point C in the middle.

[0041] In some embodiments, at least two heat exchange areas include a first area 110 close to the air outlet and a second area 120 away from the air outlet. The spacing between the fin assembly 130 located in the first area 110 and the adjacent fin assembly 130 is 20mm-22mm, and the spacing between the fin assembly 130 located in the second area 120 and the adjacent fin assembly 130 is 11mm-13mm.

[0042] In this embodiment, the distance between the fin assembly 130 located in the first area 110 and the adjacent fin assembly 130 is N1, and the distance between the fin assembly 130 located in the second area 120 and the adjacent fin assembly 130 is N2, wherein N1 is greater than N2.

[0043] Specifically, the spacing between the fin assembly 130 located in the first area 110 and the adjacent fin assembly 130 is 21.65 mm, and the spacing between the fin assembly 130 located in the second area 120 and the adjacent fin assembly 130 is 12.7 mm. When the airflow from the air outlet blows toward the windward surfaces on both sides of the heat exchanger 100, the fin assembly 130 located in the first area 110 and the fin assembly 130 located in the second area 120 can maximize the uniformity of the airflow flowing into the heat exchanger 100 and reduce the wind noise of the fins 131 caused by uneven airflow.

[0044] In some embodiments, the plane where the first side A1 is located and the plane where the second side A2 is located extend along the first direction X and the second direction Y respectively, and the ratio of the length of the heat exchange area close to the air outlet in the first direction X or the second direction Y to the length of the adjacent heat exchange area far from the air outlet in the first direction X or the second direction Y is 0.9-1.2.

[0045] like Figure 2 As shown, in this embodiment, the first side A1 and the second side A2 of the heat exchanger 100 include a first area 110 close to the air outlet and a second area 120 away from the air outlet. The height of the first area 110 of the first side A1 in the first direction X is H1, and the height of the second area of ​​the first side A1 in the first direction X is H2, and the ratio of H2 to H1 is 0.9-1.2.

[0046] Specifically, in a preferred embodiment, the ratio of the lengths of adjacent heat exchange areas in the first direction X or the second direction Y is 0.95-1.05. Since the wind speed of the windward surface decreases linearly from the side close to the air outlet to the side far from the air outlet when the airflow from the air outlet flows toward the windward surface of the first side A1 and the second side A2 of the heat exchanger 100, the uniformity of the airflow flowing into the heat exchanger 100 can be maximized when the ratio of the lengths of adjacent heat exchange areas in the first direction X or the second direction Y is approximately 1.0.

[0047] In some embodiments, the heat exchanger 100 further includes a plurality of heat pipes, and the heat pipes are disposed through the fin assembly 130 ; the ratio of the spacing between the plurality of fin assemblies 130 in the same heat exchange region to the diameter of the heat pipe is 1.33-3.09.

[0048] In this embodiment, the diameter of the heat pipe is 7 mm to 9.52 mm, and when the spacing between the fin assembly 130 located in the first area 110 and the adjacent fin assembly 130 is 21.65 mm, and the spacing between the fin assembly 130 located in the second area 120 and the adjacent fin assembly 130 is 12.7 mm, the ratio of the spacing between the multiple fin assemblies 130 located in the first area 110 to the diameter of the heat pipe is 2.27-3.09, and the ratio of the spacing between the multiple fin assemblies 130 located in the second area 110 to the diameter of the heat pipe is 1.33-1.81.

[0049] When the first side A1 and the second side A2 have multiple heat exchange areas, the first area 110 is located at the position closest to the air outlet on the first side A1 and the second side A2, the second area 120 is located at the position farthest from the air outlet on the first side A1 and the second side A2, and other heat exchange areas are located between the first area 110 and the second area 120. The spacing of the multiple fin assemblies 130 in other heat exchange areas is 12.7mm-21.65mm, and the ratio of the spacing of the multiple fin assemblies 130 in other heat exchange areas to the diameter of the heat pipe is 1.33-3.09. In this embodiment, when the ratio of the diameter of the heat pipe to the spacing of the fin assemblies 130 is in the range of 1.33-3.09, the fin assembly 130 can evenly guide the airflow into the heat exchanger 100 while maintaining a high heat exchange efficiency of the heat pipe, so that the heat exchanger 100 can ensure the heat exchange efficiency while improving the uniformity of the airflow flowing into the heat exchanger 100.

[0050] In some embodiments, an angle between a plane extending along the first direction X and a plane extending along the second direction Y is 10° to 160°.

[0051] Specifically, in a preferred embodiment, the angle between the plane extending along the first direction X and the plane extending along the second direction Y is 30° to 60°. In this embodiment, the cross section of the heat exchanger 100 is trapezoidal, and the planes where the first side A1 and the second side A2 of the heat exchanger 100 are located form an angle, so that the windward surfaces of the first side A1 and the second side A2 are inclined to increase the contact area with the air, improve the heat exchange efficiency of the heat exchanger 100 and the uniformity of the airflow when flowing into the heat exchanger 100.

[0052] Figure 7 This is a schematic structural diagram of a fixing member 140 of a first embodiment of a heat exchanger 100 of the utility model. Figure 8 The utility model heat exchanger 100 Figure 7In some embodiments, the heat exchanger 100 further includes a fixing member 140, and adjacent fin assemblies 130 located in different heat exchange areas are connected to each other through the fixing member 140.

[0053] In this embodiment, the fin assembly 130 of the first area 110 is connected to the fin assembly 130 of the second area 120 through two fixing members 140, and the two ends of the fixing member 140 are respectively connected to the fin assembly 130 of the first area 110 and the fin assembly 130 of the second area 120, and screws can fix the fin assembly 130 of the first area 110 and the fin assembly 130 of the second area 120 through the screw holes at both ends of the fixing member 140.

[0054] In some embodiments, the plurality of fin assemblies 130 are an integrated structure. In this embodiment, the plurality of fin assemblies 130 are connected by an integrated structure, which ensures the structural strength and stability of the connection of the plurality of fin assemblies 130 .

[0055] In some embodiments, each fin assembly 130 includes a plurality of fins 131 spaced apart from each other, and the difference between the spacing between the fins 131 of the fin assembly 130 close to the air outlet and the spacing between the fins 131 of the adjacent fin assembly 130 away from the air outlet is 0.2 times the preset fin spacing.

[0056] like Figure 4 , Figure 5 As shown, in this embodiment, the spacing between the fins 131 of the fin assembly 130 located in the first area 110 is L1, and the spacing between the fins 131 of the fin assembly 130 located in the second area 120 is L2. The difference between L2 and L1 is 0.2 times the preset fin spacing, so that the fin spacing of the fins 131 of the fin assembly 130 can be uniformly increased from the side close to the air outlet to the side away from the air outlet, wherein the preset fin spacing is the preset fin 131 spacing.

[0057] Since the wind speed on the side of the heat exchanger 100 away from the air outlet is smaller, and the wind speed on the side close to the air outlet is larger, the first area 110 is located on the side close to the air outlet, and the second area 120 is located on the side away from the air outlet. Therefore, the spacing between the fins 131 of the fin assembly 130 located in the first area 110 is smaller than the spacing between the fins 131 of the fin assembly 130 located in the second area 120, that is, L1 is smaller than L2, so that the fin assemblies 130 located in different heat exchange areas can be set corresponding to airflows of different flow rates at different heights of the windward surface for diversion. At the same time, the spacing between the fins 131 of the fin assembly 130 increases uniformly from the side close to the air outlet to the side away from the air outlet, thereby ensuring the uniformity of the airflow flowing into the heat exchanger 100.

[0058] In some embodiments, the preset sheet spacing is 1.2 mm-2.0 mm. For example, when the preset sheet spacing is 1.5 mm, the difference between L2 and L1 can be 0.3 mm, 0.6 mm, 0.9 mm, or 1.2 mm.

[0059] In this embodiment, when the heat exchange area includes the first area 110 and the second area 120, the spacing between the fins 131 of the fin assembly 130 of the second area 120 is 1.5 mm, and the spacing between the fins 131 of the fin assembly 130 of the first area 110 is 1.2 mm. When the heat exchange area includes three or more heat exchange areas, the spacing between the fins 131 of the fin assembly 130 of the heat exchange area far from the air outlet is 1.5 mm, and the spacing between the fins 131 of the fin assembly 130 of the heat exchange area from the side far from the air outlet to the side close to the air outlet is reduced in sequence by 0.3 mm, so that the spacing between the fins 131 can change evenly with the wind speed on the windward side, ensuring the uniformity of the airflow flowing into the heat exchanger 100.

[0060] Figure 6 1 is a schematic diagram of the structure of the second embodiment of the heat exchanger 100 of the utility model. Part of the structure of the second embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.

[0061] In the second embodiment of the heat exchanger 100 of the utility model, the first side A1 and the second side A2 are respectively provided with a first area 110, a second area 120, and a third area 150. The spacing between the fins 131 of the fin assembly 130 in the second area 120 is 1.5 mm, the spacing between the fins 131 of the fin assembly 130 in the third area 150 is 1.2 mm, and the spacing between the fins 131 of the fin assembly 130 in the first area 110 is 0.9 mm. The spacing between the fins 131 can change evenly with the wind speed on the windward side to ensure the uniformity of the airflow flowing into the heat exchanger 100. In addition, the spacing between the multiple fin assemblies 130 in the first area 110 is 20 mm-22 mm, the spacing between the multiple fin assemblies 130 in the second area 120 is 11 mm-13 mm, and the spacing between the multiple fin assemblies 130 in the third area 150 is 16 mm-18 mm.

[0062] In a preferred embodiment, the pitch of the plurality of fin assemblies 130 in the first region 110 is 21.65 mm, the pitch of the plurality of fin assemblies 130 in the second region 120 is 12.7 mm, and the pitch of the plurality of fin assemblies 130 in the third region 150 is 17.2 mm.

Fig.101 is a structural block diagram of an embodiment of a heat pump machine 200 of the utility model.

Multiple pipes 230 are used to transport gaseous medium, liquid medium or refrigerant medium. The controller 240 is electrically connected to the airflow driving component 220 and the compressor 210. The controller 240 is configured to control the start and stop of the airflow driving component 220 and the compressor 210.

[0065] The heat exchanger 100 includes a plurality of fin assemblies 130 , which are respectively arranged on the first side A1 and the second side A2 , and the spacing between the fin assemblies 130 close to the air outlet is greater than the spacing between the fin assemblies 130 far from the air outlet.

[0066] The compressor 210 can control the refrigerant medium to change from low temperature and low pressure to high temperature and high pressure, and circulate the refrigerant medium through the pipeline 230 to achieve heat release. The airflow driving member 220 can drive the external airflow to flow into the heat pump 200 through the fin assembly 130 to achieve heat exchange.

[0067] The controller 240 is electrically connected to the airflow driving component 220 and the compressor 210. The controller 240 can control the start and stop of the airflow driving component 220 and the compressor 210, and issue instructions to control the heat pump 200 to achieve control of parameters such as power and air intake of the heat pump 200.
