Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a fin assembly, a heat exchanger and a heat pump. Background Art

[0002] When the heat pump is in the heating process, the airflow blowing to the windward surface of the heat pump fin is uneven, resulting in different air intakes at different heights of the heat pump fin, causing the heat exchange of the heat exchanger to decay, affecting the heating efficiency of the heat pump, and causing the fins to generate wind noise, affecting the heating efficiency of the heat pump. In addition, during the heating process of the heat pump, the area with slower wind speed on the windward surface of the fin is prone to frost blocking the gaps between the fins, causing a sharp increase in wind resistance.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The embodiments of the utility model provide a fin assembly, a heat exchanger and a heat pump, which can make the air flow evenly flow into the heat exchange assembly.

[0033] like Figures 1 to 6 As shown, in an embodiment of the utility model, the fin assembly includes at least one pair of guide members 100 respectively arranged on both sides of the heat exchange assembly 210, each guide member 100 includes at least two fin groups 110, the fin group 110 includes a plurality of fins 111 arranged at intervals, the fins 111 of the guide members 100 located on both sides of the heat exchange assembly 210 are arranged at intervals along the first direction X and the second direction Y, respectively, an angle is formed between the plane extending along the first direction X and the plane extending along the second direction Y, and the spacing between the fins 111 of the fin group 110 close to the air outlet is smaller than the spacing between the fins 111 of the fin group 110 away from the air outlet.

[0034] In the embodiment of the utility model, both sides of the heat exchange component 210 are provided with guides 100, and the surface of the guide 100 is the windward surface. When the air flows toward the guide 100, the wind speed of the windward surface of the guide 100 close to the air outlet is relatively high, and the wind speed of the side away from the air outlet is relatively low. The guide 100 in the embodiment of the utility model includes at least two fin groups 110, and the fin spacings of different fin groups 110 are different. By setting the fin group 110 with a larger fin spacing at a position with a lower wind speed, and setting the fin group 110 with a smaller fin spacing at a position with a higher wind speed, the uniformity of the airflow flowing into the heat exchange component 210 is improved, the heat exchange efficiency of the heat exchange component 210 is improved, and the wind noise of the fin 111 is reduced.

[0035] Different fin groups 110 of the fin assembly of the embodiment of the utility model are arranged at different positions on both sides of the heat exchange component 210. Since the wind speeds at different positions on the windward surface of the heat exchange component 210 on both sides are different, by arranging the fin groups 110 with different fin spacings at corresponding positions on both sides of the heat exchange component 210, the guide member 100 can guide the airflow at different positions on the windward surface through the fin groups 110 with different fin spacings, thereby improving the uniformity of the airflow flowing into the heat exchange component 210 and the heat exchange efficiency of the heat exchange component 210, and reducing the wind noise of the fins 111.

[0036] like Figure 1 As shown, in one embodiment of the utility model, the fin group 110 includes a first fin group 120 and a second fin group 130, the first fin group 120 and the second fin group 130 are connected to each other, the first fin group 120 is arranged on the side of the heat exchange component 210 close to the air outlet, and the second fin group 130 is arranged on the side of the heat exchange component 210 away from the air outlet, and the spacing between the fins 111 of the first fin group 120 is smaller than the spacing between the fins 111 of the second fin group 130.

[0037] In the embodiment of the utility model, the guide 100 is arranged on the windward surface of both sides of the heat exchange component 210, and the airflow flows into the heat exchange component 210 through the fin group 110 of the guide 100. The wind speed on the side of the heat exchange component 210 away from the air outlet is relatively low, and the wind speed on the side close to the air outlet is relatively high. Since the fin pitch of the first fin group 120 of the guide 100 is smaller than the fin pitch of the second fin group 130, by arranging the first fin group 120 on the side of the heat exchange component 210 close to the air outlet, and the second fin group 130 on the side of the heat exchange component 210 away from the air outlet, the fin groups 110 with different fin pitches can guide the airflows with different flow rates at various height positions on the windward surface of the guide 100, thereby ensuring the uniformity of the airflow flowing into the heat exchange component 210.

[0038] Optionally, each guide member 100 includes a plurality of fin groups 110 , and the plurality of fin groups 110 located on both sides of the heat exchange component 210 are respectively arranged along the first direction X and the second direction Y and are connected to each other.

[0039] like Figure 2As shown, in another embodiment of the utility model, the fin group 110 includes a plurality of fin groups 110, for example, the fin groups 110 are respectively a first fin group 120, a second fin group 130 and a third fin group, the first fin group 120 is arranged on the side of the heat exchange component 210 close to the air outlet, the third fin group is arranged on the side of the heat exchange component 210 away from the air outlet, and the second fin group 130 is arranged between the first fin group 120 and the third fin group. Since the wind speed on the windward surface of the air guide 100 gradually decreases from the side close to the air outlet to the side away from the air outlet, the fin spacing from the first fin group 120 to the third fin group gradually increases, ensuring the matching degree between the fin spacing of the air guide 100 and the wind speed, and improving the uniformity of the airflow flowing into the heat exchange component 210.

[0040] Further, the fin group 110 may also include four, five or six or more fin groups 110, each fin group 110 has a different fin spacing, and according to the different wind speeds at different height positions on the windward surface of the air guide 100, the fin groups 110 with different fin spacings are arranged at corresponding height positions on both sides of the heat exchange component 210. At a position with a higher wind speed, the fin spacing of the fin group 110 is smaller, and at a position with a lower wind speed, the fin spacing of the fin group 110 is larger. By increasing the number of fin groups 110, the fin spacing of the air guide 100 can change more evenly with the wind speed on the windward surface, thereby improving the uniformity of the airflow flowing into the heat exchange component 210.

[0041] The utility model is not limited to the arrangement of the above-mentioned embodiment. According to the wind speed at different positions of the windward surface of the air guide 100, the fin groups 110 with different fin spacings can also be arranged in other ways. For example, when the wind speed is higher on the side of the heat exchange component 210 away from the air outlet and lower on the side close to the air outlet, the fin group 110 with a larger fin spacing is arranged on the side close to the air outlet, and the fin group 110 with a smaller fin spacing is arranged on the side clamped to the ground, or the multiple fin groups 110 can also be arranged horizontally from left to right or from right to left, which is not limited here.

[0042] Optionally, the ratio of the length of the fin group 110 on the side close to the air outlet in the first direction X or the second direction Y to the length of the adjacent fin group 110 on the side away from the air outlet in the first direction X or the second direction Y is 0.9-2.0.

[0043] like Figure 1 As shown, in the embodiment of the utility model, the length of the first fin group 120 in the first direction X is H1, and the length of the second fin group 130 in the first direction X is H2, that is, the ratio of H1 to H2 is 0.9 to 2.0. For example, the length of the first fin group 120 in the first direction X is 0.9m, and the length of the second fin group 130 in the first direction X can be 0.45m to 1m.

[0044] When the number of the fin groups 110 of the air guide 100 is multiple, for example, the air guide 100 includes a first fin group 120, a second fin group 130 and a third fin group, the length of the first fin group 120 in the first direction X is H1, the length of the second fin group 130 in the first direction X is H2, and the length of the third fin group in the first direction X is H3, that is, the ratio of H1 to H2 is 0.9 to 2.0, and the ratio of H2 to H3 is 0.9 to 2.0. The ratio of the lengths of the adjacent fin groups 110 of the air guide 100 located on the other side of the heat exchange assembly 210 in the second direction Y is the same as the ratio of the lengths of the adjacent fin groups 110 of the air guide 100 in the first direction X, which will not be described here.

[0045] like Figure 5 to Figure 6 As shown, further, the spacing between the fins 111 of the fin group 110 is 1mm to 2mm, and the difference between the spacing between the fins 111 of the fin group 110 away from the air outlet and the spacing between the fins 111 of the adjacent fin group 110 close to the air outlet is 0.2mm to 0.8mm.

[0046] Specifically, the fin pitch of the first fin group 120 is D1, and the fin pitch of the second fin group 130 is D2. For example, when the guide member 100 includes a first fin group 120 and a second fin group 130, the fin pitch of the first fin group 120 is 1.6 mm, and the fin pitch of the second fin group 130 is 2 mm; when the guide member 100 includes a first fin group 120, a second fin group 130 and a third fin group, the fin pitch of the first fin group 120 is 1.2 mm, the fin pitch of the second fin group 130 is 1.6 mm, and the fin pitch of the third fin group is 2 mm; when the guide member 100 includes a first fin group 120, a second fin group 130, a third fin group and a fourth fin group, the fin pitch of the first fin group 120 is 1.2 mm, the fin pitch of the second fin group 130 is 1.4 mm, the fin pitch of the third fin group is 1.6 mm, and the fin pitch of the fourth fin group is 1.8 mm.

[0047] It is easy to imagine that the number of fin groups 110 of the guide member 100 can also be five, six or more, and different fin groups 110 are arranged on the windward surface of the heat exchange component 210 in sequence according to the fin spacing. The fin group 110 with a smaller fin spacing is arranged on the side close to the air outlet, and the fin group 110 with a larger fin spacing is arranged on the side away from the air outlet. The utility model does not limit the number of fin groups 110 of the guide member 100.

[0048] Optionally, in an embodiment of the present invention, an angle between a plane extending along the first direction and a plane extending along the second direction is 10° to 160°.

[0049] Specifically, in a preferred embodiment of the present invention, the angle between the plane extending along the first direction and the plane extending along the second direction is 30° to 60°. In other embodiments of the present invention, at least one pair of flow guides 100 can also be relatively parallelly arranged on both sides of the heat exchange assembly 210, that is, the flow guides 100 on both sides of the heat exchange assembly 210 are arranged in parallel, and the present invention does not limit the extension direction of the flow guides.

[0050] like Figure 3 , Figure 4 As shown, optionally, the guide member 100 further includes a fixing member 140 , and adjacent fin groups 110 are connected to each other via the fixing member 140 , and screw holes are provided at both ends of the fixing member 140 .

[0051] In the embodiment of the utility model, the two sides of the first fin group 120 and the second fin group 130 are connected by two fixing members 140 respectively, and the two ends of the fixing members 140 are respectively connected to the first fin group 120 and the second fin group 130, and screws can fix the first fin group 120 and the second fin group 130 through the screw holes at the two ends of the fixing members 140.

[0052] Optionally, the adjacent fin groups 110 of each guide 100 are of an integrated structure. The multiple fin groups 110 of the guide 100 in the embodiment of the utility model can also be of an integrated structure, and the fin groups 110 with different fin spacings are connected through an integrated structure to ensure the overall structural strength and stability of the guide 100.

[0053] like Figures 1 to 6 As shown, the utility model further proposes a heat exchanger 200 , which includes a fin assembly of any of the aforementioned embodiments and a heat exchange assembly 210 . The cross section of the heat exchange assembly 210 is trapezoidal, and the fin assembly is arranged on both sides of the heat exchange assembly 210 .

[0054] The fin assembly includes at least one pair of guide members 100 respectively arranged on both sides of the heat exchange assembly 210, each guide member 100 includes at least two fin groups 110, the fin group 110 includes a plurality of fins 111 arranged at intervals, the fins 111 of the guide members 100 located on both sides of the heat exchange assembly 210 are arranged at intervals along the first direction X and the second direction Y, respectively, an angle is formed between the plane extending along the first direction X and the plane extending along the second direction Y, and the spacing between the fins 111 of the fin group 110 close to the air outlet is smaller than the spacing between the fins 111 of the fin group 110 away from the air outlet.

[0055] The heat exchanger 200 of the embodiment of the utility model includes a fin assembly, and different fin groups 110 of the fin assembly are arranged at different positions on both sides of the heat exchange assembly 210. Since the wind speeds at different positions on the windward surface of the heat exchange assembly 210 on both sides are different, by arranging the fin groups 110 with different fin spacings at corresponding positions on both sides of the heat exchange assembly 210, the guide member 100 can guide the airflow at different positions on the windward surface through the fin groups 110 with different fin spacings, thereby improving the uniformity of the airflow flowing into the heat exchange assembly 210, so that the heat exchanger 200 can improve the heat exchange efficiency and reduce the wind noise generated by the fins 111 during heat exchange.

[0056] like Figures 7 to 9 As shown, the utility model also proposes a heat pump machine 300, which includes the heat exchanger 200, a compressor 310, an air flow driving component 320 and a plurality of pipes 330 of the aforementioned embodiment. The compressor 310 can compress the refrigerant medium and drive the refrigerant medium to circulate. The air flow driving component 320 can drive the air flow to flow to the fin assembly of the heat exchanger 200 through the air outlet. The pipe 330 is used to transport gaseous medium, liquid medium or refrigerant medium.

[0057] The fin assembly includes at least one pair of guide members 100 respectively arranged on both sides of the heat exchange assembly 210, each guide member 100 includes at least two fin groups 110, the fin group 110 includes a plurality of fins 111 arranged at intervals, the fins 111 of the guide members 100 located on both sides of the heat exchange assembly 210 are arranged at intervals along the first direction X and the second direction Y, respectively, an angle is formed between the plane extending along the first direction X and the plane extending along the second direction Y, and the spacing between the fins 111 of the fin group 110 close to the air outlet is smaller than the spacing between the fins 111 of the fin group 110 away from the air outlet.

[0058] The compressor 310 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 330 to achieve heat release. The airflow driving member 320 can drive the external airflow to flow into the heat pump 300 through the fin assembly to achieve heat exchange.

[0059] The heat pump 300 of the embodiment of the utility model includes a heat exchanger 200, which includes a fin assembly. Different fin groups 110 of the fin assembly are arranged at different positions on both sides of the heat exchange assembly 210. Since the wind speeds at different positions on the windward surface of the heat exchange assembly 210 on both sides are different, by arranging the fin groups 110 with different fin spacings at corresponding positions on both sides of the heat exchange assembly 210, the guide member 100 can guide the airflow at different positions on the windward surface through the fin groups 110 with different fin spacings, thereby improving the uniformity of the airflow flowing into the heat exchange assembly 210, thereby improving the heat exchange efficiency of the heat pump 300 and reducing the wind noise generated by the fins 111 when the heat pump 300 exchanges heat.
