Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 As shown, the air-water dual heat source three-medium composite heat exchanger includes a fan 14 and a heat exchanger body, the heat exchanger body includes a liquid distribution pipe 1 and a liquid collection pipe 2, and the liquid separation pipe 1 is divided by 3 partitions. For the first cavity 10 and the second cavity 11, the liquid collecting pipe 2 is divided into the third cavity 12 and the fourth cavity 13 by the partition plate 3, and the first cavity 10 and the fourth cavity 13 are divided by the inner tube 8 connected, the second cavity 11 and the third cavity 12 are communicated by the outer tube 5, the outer tube 5 is sleeved outside the inner tube 8, and the outer wall of the outer tube 5 is provided with fins 4, the liquid distribution tube 1 and the liquid collection Between the tubes 2 there is at least one row of outer tubes 5 .

[0019] The liquid distribution pipe 1 and the liquid collection pipe 2 are fla...

Embodiment 2

[0023] Such as Figure 4 As shown, the fins 4 are winding fins, and other structures are the same as in Embodiment 1.

Embodiment 3

[0025] Such as Figure 5 As shown, two rows of outer tubes 5 are arranged between the liquid distribution tube 1 and the liquid collection tube 2 .

[0026] As preferred option one of the present invention, such as Image 6 As shown, the two rows of outer tubes 5 are arranged in parallel.

[0027] As the second preferred scheme of the present invention, such as Figure 7 As shown, between the two rows of outer tubes 5 is a fork row form, which is also called a dislocation form.

Abstract

The invention belongs to the field of manufacture of heat exchanger, particularly discloses an air-water double heat source three-media compound heat exchanger. The air-water double heat source three-media compound heat exchanger comprises a fan and a heat exchanger body. The heat exchanger body comprises a liquid dividing tube and a liquid gathering tube. The liquid dividing tube is divided into a first chamber and a second chamber by a partition plate. The liquid gathering tube is divided into a third chamber and a fourth chamber by a partition plate. The first chamber is communicated with the fourth chamber through an inner tube and the second chamber is communicated with the third chamber through an outer tube. The outer tube is sleeved outside the inner tube. A fin is arranged on the outer wall of the outer tube. At least a row of outer tubes is arranged between the liquid dividing tube and the liquid gathering tube. According to the invention, the inner tube and the outer tube are straight tubes which are simple to process, and the inner tube and the outer tube are easier to sleeve. Compared with the prior art, the compound heat exchanger of the invention is simple in manufacturing process and is suitable for popularization in a large scale.

Description

technical field [0001] The invention relates to the field of heat exchanger processing and manufacturing, in particular to a heat exchanger capable of realizing synchronous heat exchange of three media in the same heat exchanger. Background technique [0002] The resources at home and abroad are increasingly tight, and building energy consumption is a major energy consumption item. Converting low-grade heat energy that cannot be directly used into heat pump technology that can use high-level energy is an important way for air conditioning to save energy. Combined with the air source heat pump technology, a dual heat source composite heat pump technology is produced. This technology adopts a dual-heat-source three-medium composite heat exchanger, which can realize air and low-temperature solar hot water or ground-energy water as the heat source of the heat pump system at the same time, and can effectively solve a series of problems existing in single heat source heat pumps. F...
