Embodiment 1

[0028] see Figure 1~3 , in an embodiment of the present invention, a water-cooled parallel-flow heat exchanger with flat tubes in a row includes a first heat exchanger 100, and the first heat exchanger 100 is used to exchange heat for air; the first heat exchanger The device 100 includes a first header 01 and a second header 02, through which the circulation of air is facilitated, and heat is exchanged during the circulation of the air.

[0029] The installation pipe 14 is fixed on the first header 01 and the second header 02, and the installation pipe 14 is detachably connected with the flat pipe 03, which facilitates the installation and disassembly of the flat pipe 03, and the flat pipe 03 is used for air circulation , when the hot air circulates in the flat tubes 03, heat exchange is carried out; the number of the flat tubes 03 is multiple, and the residence time of the hot air in the flat tubes 03 can be improved by arranging a plurality of flat tubes 03, thereby obtaini...

Embodiment 2

[0035] see Figure 4~5 The difference between this embodiment of the present invention and Embodiment 1 is that a spoiler assembly 06 is also provided on the flat tube 03, and the heat exchange efficiency is improved through the spoiler assembly 06; the spoiler assembly 06 includes The lap pipe 62 on 03, the lap pipe 62 communicates with the flat pipe 03 at both ends respectively, the lap pipe 62 is provided with a rotating shaft 65, that is, the rotating shaft 65 runs through all the lap pipes 62, and the rotating shaft 65 is located in the lap pipe 62 A fixed sleeve 63 is provided, and the fixed sleeve 63 is provided with a stirring rod 64. When the rotating shaft 65 rotates, it can drive the fixed sleeve 63 to rotate, and then drive the stirring rod 64 to rotate, and the cooling water in the lap pipe 62 Cooling is very simple. At the same time, one end of the overlapping pipe 62 is fixed to the output shaft of the motor 61, and then the motor 61 drives the rotating shaft 65...

Embodiment 3

[0037] see Figure 6-8 , a second heat exchanger 200 and a third heat exchanger 300 are also provided below the first heat exchanger 100, the first heat exchanger 100, the second heat exchanger 200 and the third heat exchanger 300 are identical, And between the first heat exchanger 100 and the second heat exchanger 200, and between the second heat exchanger 200 and the third heat exchanger 300 are fixed by the backing plate 07 to improve the stability of the three; at the same time, the first The heat exchanger 100 and the third heat exchanger 300 are respectively fixed with the first assembly 81 and the third assembly 83, and the second heat exchanger 200 is fixed with the second assembly 82, and the two ends of the second assembly 82 are provided with There are protrusions 84, and the protrusions 84 are inserted into the grooves 85 on the first assembly 81 and the third assembly 83, and the first heat exchanger 100, the second heat exchanger 200, and the Three heat exchange...

Abstract

The invention discloses a water cooling type parallel flow heat exchanger with a flat tube bank and relates to the field of heat exchange. The water cooling type parallel flow heat exchanger with theflat tube bank mainly aims to solve the problem that the heat exchange efficiency of an existing parallel flow heat exchanger is low. The water cooling type parallel flow heat exchanger with the flattube bank comprises a first heat exchanger. The first heat exchanger comprises a first flow header and a second flow header. One end of the first flow header is provided with an air inlet. Second airholes communicating with flat tubes are arranged in the first flow header. Fourth air holes communicating with the flat tubes are arranged in the second flow header. First partition plates are arranged in the first flow header. The end, far away from the air inlet, of the second flow header is provided with a first air outlet. The flat tubes are provided with cooling pipes and flow distributing assemblies. A second heat exchanger and a third heat exchanger are arranged below the first heat exchanger. The first heat exchanger and the second heat exchanger are fixed through cushion plates and assembling pieces, and the second heat exchanger and the third heat exchanger are fixed through cushion plates and assembling pieces. The heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a water-cooled parallel-flow heat exchanger connected with flat tubes. Background technique [0002] Parallel flow heat exchanger is an all-aluminum heat exchanger with compact structure, high heat exchange efficiency, and cost advantage compared with ordinary copper tube heat exchanger, and has been paid more and more attention by various air-conditioning manufacturers. Ideally, the refrigerant should be evenly distributed into each flat tube of the parallel flow heat exchanger to ensure the best heat transfer efficiency of the parallel flow heat exchanger. [0003] The existing parallel flow heat exchanger header includes a header body, and a plurality of through holes arranged at intervals along the length direction of the header body are formed on the header body; One end in the length direction of the pipe body; at least one partition, the partition is arranged in the header bo...
