As shown in fig. 1, for a conventional microchannel heat exchanger, including two parallel headers 1 and a plurality of flat tubes 2 installed between the two headers 1 and used for connecting the two headers 1, a corrugated fin 3 is provided between the two adjacent flat tubes 2, and the operating principle is: the refrigerant enters through the collecting pipe 1, and in the flat pipe 2, the heat exchange is carried out between the refrigerant and the outside air in the process of flowing in the flat pipe 2, so that the refrigeration or heating is realized, and the corrugated fins 3 are used for improving the optimal heat exchange efficiency of the heat exchanger.

The corrugated fin 3 is used as an auxiliary heat exchange component of the microchannel heat exchanger, but in actual use, dust is easily adhered to the corrugated fin, so that the overall heat exchange efficiency of the microchannel heat exchanger is affected.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technical problem and provide a microchannel heat exchanger.

The utility model discloses a following technical scheme realizes: the utility model provides a microchannel heat exchanger, is equipped with the corrugate fin including two pressure manifold that set up side by side and install the many flat pipes that just are used for putting through two pressure manifold between two pressure manifold, between two adjacent flat pipes, relative face all is equipped with the spacing groove between two adjacent flat pipes, just the position that the flat pipe was hugged closely to the corrugate fin can inlay the spacing inslot, the corrugate fin keep away from one side of flat pipe and pressure manifold and seted up a plurality of holes of taking.

The utility model discloses a carry out institutional advancement to the flat pipe on the current microchannel heat exchanger, fix the corrugate fin through the spacing groove that relative face was add between adjacent two flat pipes, and then make things convenient for the dismouting of corrugate fin, be convenient for wash the change of corrugate fin to guarantee microchannel heat exchanger's heat exchange efficiency, the hole of taking of seting up on the corrugate fin simultaneously, further make things convenient for the dismouting of corrugate fin.

Preferably, the corrugated fin is provided with an elastic sheet on one side close to the limit groove of the flat tube, so that the connection structure between the corrugated fin and the limit groove is increased, and the connection structure is compact.

Preferably, the corrugated fin is composed of a plurality of small corrugated fins, and each small corrugated fin is provided with a taking hole, so that the corrugated fin is more convenient to clean.

Preferably, the hole edge of the taking hole is a round edge.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the utility model discloses a flat pipe to on the current microchannel heat exchanger carries out institutional advancement, and then makes things convenient for the dismouting of corrugate fin, is convenient for wash the change of corrugate fin to guarantee microchannel heat exchanger's heat exchange efficiency.

Description of reference numerals:

1. the collecting pipe comprises a collecting pipe body, 2 flat pipes, 21 limiting grooves, 3 corrugated fins, 31 taking holes, 32 small corrugated fins, 33 elastic sheets.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

As shown in fig. 2-4, a microchannel heat exchanger includes two parallel collecting pipes 1 and a plurality of flat pipes 2 installed between the two collecting pipes 1 and used for connecting the two collecting pipes 1, a corrugated fin 3 is provided between the two adjacent flat pipes 2, the opposite surfaces between the two adjacent flat pipes 2 are provided with a limiting groove 21, the part of the corrugated fin 3 tightly attached to the flat pipe 2 can be embedded into the limiting groove 21, and one side of the corrugated fin 3 far away from the flat pipe 2 and the collecting pipe 1 is provided with a plurality of taking holes 31.

When the corrugated fin 3 is disassembled, the taking hole 31 on the corrugated fin 3 is held and pulled outwards, and at the moment, the corrugated fin 3 is forced to slide outwards in the limiting groove 21 until the corrugated fin 3 is disassembled; when the corrugated fin 3 is installed, the corrugated fin 3 is held through the taking hole 31, the parts, close to the flat tubes 2, of the corrugated fin 3 are respectively aligned to the limiting grooves 21 on the two adjacent flat tubes 2 and pushed, and the corrugated fin 3 slides in the limiting grooves 21 under the stress until the installation of the corrugated fin 3 is completed.
