Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, a tube fin unit 100 according to an embodiment of the present invention includes a fin portion 101 and a runner portion 102 connected to each other, wherein the tube fin unit 100 has a first end portion 104 that is plugged to a current collecting structure 300. The tube fin unit 100 is further provided with a positioning assembly 200, the positioning assembly 200 is fixed on the fin part 101, and the positioning assembly 200 can limit the length of the tube fin unit 100 inserted into the collecting structure 200. Therefore, the fin units 100 can maintain the insertion length of the fin units 100 at a preset distance through the positioning assembly 200, and the uniform distribution of the current from the current collecting structure 300 to each fin unit 100 is ensured.

As shown in fig. 1 and 2, the fin unit 100 is made of heat exchange material such as aluminum alloy and copper alloy, and is formed into an integrally formed structure by extrusion or casting. The fin part 101 is in a flat plate shape, the flow channel part 102 is in a circular tube shape extending along a first direction, the fluid channel 103 extends along the length direction of the flow channel part 102 and penetrates through the flow channel part 102, wherein a plurality of flow channel parts 102 are provided, a plurality of fin parts 101 are provided, the fin parts 101 and the flow channel part 102 are alternately arranged in a second direction (the second direction is perpendicular to the first direction), and two adjacent fin parts 101 are separated by the flow channel part 102 to form the plate-shaped tube fin body 100. The plurality of flow path portions 102 are arranged at equal intervals in the second direction by a distance N, and both ends of the tube fin unit 100 in the second direction are preferably fin portions 101. Meanwhile, both ends of the fin unit 100 in the first direction are first end portions 104. In addition, the number of the flow path portion 102 may be one, and the flow path portion 102 may be a flat pipe, a square pipe, or the like.

Regarding the tube fin unit 100, the thickness of the fin part 101 of the tube fin unit 100 is H, the thickness of the fin part 101 is recommended to be 0.4mm or less on the premise that the process can be achieved, the thicker thickness causes higher wind resistance and higher cost, the thinner fin part 101 can reduce the wind resistance, and when the same heat exchange amount is ensured, the fin distance can be reduced, so that the heat exchanger is more compact. The diameter of the fluid channel 103 of the tube fin monomer 100 is D, and the numerical value of D is 0.4mm or less, so that the filling amount of the refrigerant in the system is reduced, the tube diameter is small, and the wind resistance is also reduced. For example, when H is 0.3mm, D is 0.35mm, the number of the runner portions 102 is 4, and the distance between the adjacent fin units is 1.5mm, the heat exchange amount per unit windward area of the heat exchanger is improved by 9%, and the wind resistance is increased by 1%. For example, when H is 0.2mm, D is 0.35mm, the number of the flow channel parts 102 is 4, and the distance between the adjacent fin units is 1.4mm, the heat exchange amount per unit windward area of the heat exchanger is increased by 12%, and the wind resistance is reduced by 8%. It can be seen that the fin-shaped element 100 enhances the heat exchange capacity of the heat exchanger.

As also shown in fig. 1 and 2, the positioning assembly 200 is two positioning bosses 201, and the two positioning bosses 201 are located on the fin portion 101 and near the first end portion 104. The two positioning bosses 201 are identical in shape and are rectangular block-shaped, the two positioning bosses 201 are respectively arranged on the two fin parts 101 and are located on the plate surface on one side of the tube fin unit 100, and the two positioning bosses 201 are the same in distance from the first end part 104. The positioning boss 201 is made of the same material as the fin portion 101 and the flow path portion 102, and the positioning boss 201 may be integrally molded with the fin portion 101, but is not limited thereto, and the positioning boss 201 may be fixed to the fin portion 101 by welding, caulking, or the like.

In some exemplary embodiments, as shown in fig. 3 and 4, the positioning boss 201 is semi-cylindrical, such that an outer surface of the positioning boss 201 includes two first end surfaces 205 facing the two first end portions 103, respectively, and an arc-shaped cylindrical surface 206 located between the two first end surfaces 205. Therefore, when wind flows through the air duct between the two tube fin units 100, the arc-shaped cylindrical surface 206 relatively brings smaller wind resistance, and the integral resistance reduction is facilitated. In addition, the arc-shaped cylindrical surface 206 may be an arc surface only at the portion close to the runner portion 102, and the other portions may be planes parallel to the fin portion, which may also reduce the wind resistance flowing through the fin unit 100.

In some exemplary embodiments, as shown in fig. 5, the tube fin unit 100 has a first end portion 104 at both ends in the first direction, the tube fin unit 100 has a plurality of positioning bosses 201, and two first bosses 203 and two second bosses 204 are included in the plurality of positioning bosses 201. The first bosses 203 and the second bosses 204 are identical in shape, and the distance between the first bosses 203 and the first end portions 104 close to the first bosses 203 is equal to the distance between the second bosses 204 and the first end portions 104 close to the first bosses 104, so that the first bosses 203 can limit the depth of inserting one first end portion 104 into the current collecting structure 300, and the second bosses 204 can limit the depth of inserting the other first end portion 104 into the current collecting structure 300, so that the two ends of the tube fin unit 100 can be limited.

In some exemplary embodiments, as shown in fig. 6, positioning bosses 201 are provided on both side plate surfaces of the single tube fin 100, and the positioning bosses 201 on both sides can limit the insertion length of the single tube fin 100 together, so as to increase the stability.

In some exemplary embodiments, the positioning boss 201 is disposed on the runner portion 102, and is of an integral structure with the runner portion 102, which may also limit the depth of insertion of the tube fin unit 100.

In some exemplary embodiments, the positioning bosses 201 are disposed at both ends of the single tube fin body 100 in the second direction, instead of on the plate surface, and may also limit the depth of insertion of the single tube fin body 100.

In some exemplary embodiments, as shown in fig. 7 and 8, a heat exchanger includes two manifold structures 300 and a plurality of the fin units 100 described above, the plurality of fin units 100 being arranged in parallel and spaced apart, the two first ends 104 of each fin unit 100 being insertable into the two manifold structures, and the positioning assembly 202 being abuttable to the manifold structures 300 to limit the depth of insertion of the fin units 100.

As further shown in fig. 7 and 8, the manifold structure 300 includes a substrate 301, the substrate 301 has a plurality of slots 302 on one side thereof and an inlet/outlet (not shown) at one end thereof, and a manifold pipe (not shown) is disposed in the substrate 301 and is connected to the slots 302 and the inlet/outlet. The fin units 100 are identical in size and structure, the fin units 100 are respectively inserted into the slots 302 of the two collecting structures 300 and further fixed by welding, so that a plurality of fin units 100 are arranged in parallel and at intervals, the fluid channels 104 are communicated with the two collecting structures 300, one of the two collecting structures 300 acts on collecting and the other acts on shunting. The distance between two adjacent tube fin monomers 100 is a pitch, an air channel is formed between the two tube fin monomers 100, the distance between the two tube fin monomers 100 is S, S is smaller than or equal to 1.6mm, and the flow channel parts 102 on the two adjacent tube fin monomers 100 are in one-to-one correspondence. When the heat exchanger operates, the refrigerant enters one collecting structure 300, then is distributed to flow into the fluid channel 104 of each tube fin monomer 100, is evaporated or condensed, exchanges heat with the external air, and then is collected in the other collecting structure 300 and flows out.

As shown in fig. 7, one end of the positioning boss 101 abuts against an end surface of the base plate 301 provided with the insertion groove 302, thereby restricting the insertion amount of the fin unit 100.

In some exemplary embodiments, as shown in fig. 9, the flow channel portions 102 on two adjacent fin units 100 are arranged in a staggered manner, rather than in a one-to-one correspondence, so that the minimum sectional area of the air duct can be increased, airflow disturbance can be enhanced, and the effects of reducing wind resistance and improving heat exchange efficiency can be achieved.

As shown in fig. 9, two fin units 100 are arranged in parallel, and the distance between two adjacent flow path portions 102 in the same fin unit 100 is N. One flow channel part on one tube fin unit 100 is a first flow channel 105, a projection of the first flow channel 105 on the adjacent tube fin unit 100 is a first projection, a position of the first projection is located at a projection point 400, a distance between the projection point 400 and the adjacent two flow channel parts (i.e., the second flow channel 106) is set to be M, where N is 2M, that is, the first flow channel 105 is centered with respect to the second flow channel 106. The other flow channel parts 102 also adopt the same structure, namely the projection on the adjacent tube fin units 100 and the adjacent flow channel parts 102 are all at the interval of M,
