Abstract
The invention discloses a kind of air counterflow heat exchanger. It comprises several groups of air channels. The character lies in: each group of air channel is made up of the first air channel and the second air channel which are all hollow. One side of the first air channel has a close board and the downward aperture, the other side of the first air channel has a upward aperture and the downward close board, one side of the second air channel has a upward aperture and the downward close board, the other side of the air channel has upward close board and the downward aperture.
Description
Technical field
The present invention relates to field of heat exchangers, relate in particular to the air inversion heat exchanger.
Background technology
Air one air heat exchanger has a wide range of applications in the engineering field.Existing air-to-air heat exchanger all is the distributary heat exchange from flow process.But from the angle of thermal conduction study, best heat exchange mode is a countercurrent flow, and under the same heat transfer boundary condition, the effect of contra-flow heat exchanger is better than cross-flow heat exchanger.From thermodynamic (al) angle, countercurrent flow can be realized the uniform temperature difference, and the irreversible loss that makes heat transfer process produce is little, can realize better effect than the cross-flow heat exchanger contra-flow heat exchanger.And do not see product or report in the prior art about countercurrent flow.
Summary of the invention
At the problem that prior art exists, the air inversion heat exchanger that the purpose of this invention is to provide a kind of simplicity of design, has a extensive future.
To achieve these goals, technical scheme of the present invention realizes as follows:
A kind of air inversion heat exchanger comprises many group air flow channels.Its design feature is that each is organized air flow channel and is made up of the first air flow channel sheet and the second air flow channel sheet of hollow.One side of the described first air flow channel sheet has last closure plate and lower open end, the opposite side of the first air flow channel sheet has upper open end and following closure plate, one side of the second air flow channel sheet has upper open end and following closure plate, and the opposite side of the second air flow channel sheet has last closure plate and lower open end.Above-mentioned respectively organize air flow channel be shaped as rectangle, worker's shape or
Shape.
When the present invention used, one air flow to the first air flow channel sheet by the lower open end of the first air flow channel sheet, flows out the first air flow channel sheet from upper open end; Another strand air flows to the second air flow channel sheet from the upper open end of the second air flow channel sheet, flows out the second air flow channel sheet from lower open end.Like this, two strands of air have been realized the countercurrent heat-transfer mass transfer of air in air flow channel, and efficient is higher than the fork heat exchanger.Simplicity of design of the present invention, the flow process of being convenient to arrange two strands of air, Application Prospect is wide in engineering.
Description of drawings
Fig. 1 is a principle schematic of the present invention;
Fig. 2 is an internal structure schematic diagram of the present invention.
Specify embodiments of the present invention with reference to the accompanying drawings.
The specific embodiment
Referring to Fig. 1, a kind of air inversion heat exchanger comprises many group air flow channels, whole heat exchanger is made up of a lot of sheet air flow channel sheets, each sheet all is a hollow, be the equal of the runner of an air, just can realize the countercurrent flow of air by the relative putting position of local openings different on the air flow channel sheet and air flow channel sheet.
Referring to Fig. 2, each is organized air flow channel and is made up of the first air flow channel sheet 1 and the second air flow channel sheet 2 of hollow, one side of the described first air flow channel sheet 1 has last closure plate 3 and lower open end 7, the opposite side of the first air flow channel sheet 1 has upper open end 11 and following closure plate 13, the opposite side that one side of the second air flow channel sheet 2 has upper open end 4 and following closure plate 8, the second air flow channel sheets 2 has last closure plate 12 and lower open end 16.When heat exchanger was worked, one air 5 entered in the air flow channel sheet from the upper open end 4 of air flow channel sheet 2, and the heat exchanger of flowing through from top to bottom is at last from lower open end 16 outflow heat exchangers of air flow channel sheet 2.The flow direction of air 5 is from top to bottom.Another strand air 9 flows in the air flow channel sheet 1 from the lower open end 7 of air flow channel sheet 1, and the heat exchanger of flowing through from top to bottom is at last from upper open end 11 outflow heat exchangers of air flow channel sheet 1.The flow direction of air 9 is from top to bottom.This shows that on the contact-making surface of two air flow channel sheets two strands of air have been realized countercurrent flow.When so many groups air flow channel is stacked up, just can be implemented in the countercurrent flow of realizing air on the interface of each air.At the air quantity that the size of air flow channel sheet upper shed can be handled according to heat exchanger, a plurality of combined factors such as heat exchanger volume determine, when the opening of air flow channel sheet more hour, the counter flow action of air is obvious more, heat exchange efficiency is also just high more.When one air enters heat exchanger again from original import department outflow heat exchanger from original exit, still can realize the countercurrent flow of two strands of air, and this does not exceed the scope of this patent simultaneously.And when the material of this heat exchanger transmission can be steam, or the molecule of other gases, using this heat exchanger is exactly the heat and mass of realizing adverse current, efficient is higher.
Claims (2)
1. air inversion heat exchanger, comprise many group air flow channels, it is characterized in that, each is organized air flow channel and is made up of the first air flow channel sheet (1) and the second air flow channel sheet (2) of hollow, one side of the described first air flow channel sheet (1) has last closure plate (3) and lower open end (7), the opposite side of the first air flow channel sheet (1) has upper open end (11) and following closure plate (13), one side of the second air flow channel sheet (2) has upper open end (4) and following closure plate (8), and the opposite side of the second air flow channel sheet (2) has last closure plate (12) and lower open end (16).
