Embodiment 1

[0025] Please refer to figure 1 and figure 2 , the present invention provides a heat exchange structure 100, comprising an outer tube 10 for containing a heat exchange medium and an inner tube 20 installed in the outer tube 10 for containing a heat exchange medium, the outer wall of the inner tube 20 is connected to the outer wall of the outer tube 10 There is a heat exchange channel 30 between the inner walls of the inner tube 20. The side wall of the inner tube 20 is provided with a number of jet holes 21 arranged at intervals and connected to the inside of the inner tube 20. The heat-exchanged medium in the inner tube 20 can be ejected from the jet holes 21 into the In the hot channel 30, the ejected heat exchange medium rotates in the heat exchange channel 30 and on the outer wall of the outer tube 10, and the heat exchange medium flows laterally, which accelerates the flow velocity of the heat exchange medium, thereby improving the heat exchange efficiency.

Embodiment 2

[0030] Please refer to figure 1 and figure 2 , the present embodiment provides a heat exchange device 200, comprising a shell 40, a number of spaced inner tubes 20 installed in the shell 40, and a number of spaced outer tubes 10 installed in the shell 40, each inner tube 20 corresponds to the space between two adjacent outer tubes 10, and heat exchange passages 30 are formed between the inner tube 20 and the two adjacent outer tubes 10, and the side walls of the inner tube 20 are provided with several intervals and communicated with the inner tubes. The jet hole 21 inside the inner tube 20, the heat exchange medium in the inner tube 20 can be sprayed out to the heat exchange channel 30 through the jet hole 21, and the ejected heat exchange medium is in the heat exchange channel 30 and revolves on the outer wall of the outer tube 10, The flow rate of the heat-exchanged medium is accelerated, thereby improving the heat-exchange efficiency. The top of the shell 40 is provided ...

Embodiment 3

[0035] This embodiment provides a heat exchange method, which includes the following steps:

[0036] The heat exchange medium is installed in the outer tube 10; the heat exchange medium is installed in the inner tube 20, and the side wall of the inner tube 20 is provided with a number of jet holes 21 arranged at intervals and connected to the inside of the inner tube 20, and the heat exchange medium is flowed by the jet The hole 21 shoots out and swirls between the outer wall of the inner tube 20 and the inner wall of the outer tube 10 to heat the heat exchange medium.

[0037] The central axis of the jet hole 21 and the central axis of the inner tube 20 may or may not be perpendicular, and the non-perpendicular arrangement may be used. In this embodiment, the central axis of the jet hole 21 and the central axis of the inner tube 20 are non-perpendicularly arranged so that the heat-exchanged medium shoots toward the diagonal of the heat-exchange channel 30 , increasing the flo...

Abstract

The invention discloses a heat exchange structure, a heat exchange device and a heat exchange method. The heat exchange structure comprises an outer tube for containing a heat exchange medium and an inner tube which is installed in the outer tube and is used for containing a heat-exchanged medium, a heat exchange channel is formed between the outer wall of the inner tube and the inner wall of theouter tube, a plurality of spray holes which are arranged at intervals and communicate with the interior of the inner tube are formed in the side wall of the inner tube, and the heat-exchanged mediumin the inner tube can be sprayed out of the spray holes to the heat exchange channel; and the heat exchange device comprises the heat exchange structure above. The heat exchange device can improve heat exchange efficiency and is not easy to scale.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange structure, a heat exchange device and a heat exchange method. Background technique [0002] Heat exchange is a heat exchange method in which the heat exchange medium exchanges heat with the heat exchange medium, and is usually realized by an evaporator. At present, the evaporation process of the evaporator is mainly divided into membrane evaporation and forced circulation flash evaporation. The former has high efficiency but is prone to scaling; the latter is not easy to scale but has low efficiency. Contents of the invention [0003] Based on this, it is necessary for the present invention to provide a heat exchange structure that can improve heat exchange efficiency and is not prone to fouling. [0004] The invention also provides a heat exchange device. [0005] The invention also provides a heat exchange method. [0006] In order to realize the purp...
