Problems solved by technology

[0004] in such as figure 1 , figure 2 In the shown existing microchannel heat exchanger 10, the spatial distance between the microchannel flat tubes 11 and the fins 12 is relatively small, and there are more barriers when the water flow is discharged in the vertical direction, which will affect the microchannel heat exchanger. Excellent drainage and defrosting performance

Embodiment 1

[0033] Such as image 3 , Figure 4 As shown, the flat fins 20 provided by the embodiment of the present invention are arranged along the vertical direction, wherein the flat fins 20 are provided with microchannel flat tube installation grooves 21 . in:

[0034] At least one side of the flat fin 20 is provided with a water guiding plate 22 perpendicular to the flat fin 20 . The water guide plate 22 is used to collect and guide the condensed water on the flat fins to the edge of the flat fins.

[0035] Specifically, the water guiding plate 22 is arranged at a certain angle with the horizontal plane, wherein the angle of the included angle is less than 30°. Exemplary, such as image 3 As shown, wherein, the angle θ<30° between the water guide plate 22 and the horizontal plane.

[0036] In one implementation, the water guide plate 22 can be as image 3 straight line shown. In other implementation manners, the water guiding plate 22 may also adopt structures of other shapes...

Embodiment 2

[0063] Embodiments of the present invention also provide a microchannel heat exchanger 40, such as Figure 11 As shown, the microchannel flat tube 30 is included, and the flat plate fin 20 provided in the above embodiment is also included. Wherein, the microchannel flat tube 30 passes through the microchannel flat tube installation groove 21 ( Figure 11 The micro-channel flat tube installation groove 21 is not shown in the figure, and the description about the micro-channel flat tube installation groove 21 can refer to the corresponding content of the first embodiment above).

[0064] Additionally, if Figure 11 As shown, in the microchannel heat exchanger 40, there are a plurality of flat fins 20, and the plurality of flat fins 20 are evenly spaced, and the microchannel flat tubes 30 are installed through the microchannel flat tubes of the plurality of flat fins 20 in turn. Groove 21, water guide plate 22 ( Figure 11 The water guide plate 22 is not shown in the figure, a...

Embodiment 3

[0068] An air conditioner, including a heat exchange system, wherein the heat exchange system is provided with the microchannel heat exchanger provided in the second aspect above.

[0069] In the refrigerator of the embodiment of the present invention, since the evaporator of the refrigeration cycle system is the above-mentioned microchannel heat exchanger assembly, the heat dissipation efficiency can be improved, the volume is small, the weight is light, the internal space of the refrigeration equipment is saved, and the problem of incomplete defrosting is solved. The problem.

Abstract

The invention discloses a flat fin, a microchannel heat exchanger and an air conditioner, and relates to the technical field of heat exchange. The flat fin is used for improving the drainage performance of the heat exchanger. The flat fin in the embodiment is arranged in the vertical direction, the flat fin is provided with a microchannel flat tube mounting groove, at least one side of the flat fin is provided with a water guiding plate perpendicular to the flat fin, and the water guiding plate is used for collecting and draining condensed water on the flat fin to the edge of the flat fin. Theflat fin is used for improving drainage of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a flat plate fin, a microchannel heat exchanger and an air conditioner. Background technique [0002] Compared with finned tube heat exchangers, microchannel heat exchangers have significant advantages in terms of material cost, refrigerant charge, and heat flux density, which is in line with the development trend of heat exchangers for energy conservation and environmental protection. But at the same time, due to the small space in the micro-channel heat exchanger and the fast heat transfer speed, etc., when the micro-channel heat exchanger is used as an evaporator, there are slow drainage, uneven distribution of condensate, and fast frosting. Problems such as slow defrosting limit the application of micro-channel evaporators. [0003] Specifically, a typical microchannel heat exchanger includes three major components: horizontally arranged microchannel flat tubes, fins c...
