Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
The wind-heat recoverer shown in fig. 1-6 is characterized by comprising a shell 1, a first accommodating cavity arranged in the shell 1, a heat exchanger 2 arranged in the first accommodating cavity, a partition plate 3, a cold wind channel 4, a hot wind channel 5, a liquid buffer area 6 and a gas buffer area 7, wherein the cold wind channel 4, the hot wind channel 5, the liquid buffer area 6 and the gas buffer area 7 are perpendicular to the heat exchanger 2, the partition plate 3 is vertically arranged in the middle of the heat exchanger 2 and separates the cold wind channel 4 and the liquid buffer area 6 from the hot wind channel 5 and the gas buffer area 7, the liquid buffer area 6 is arranged above the cold wind channel 4, and the gas buffer area 7 is arranged below the hot wind channel 5.
The cold air channel 4 and the liquid buffer area 6 are arranged in the second accommodating cavity, and the hot air channel 5 and the gaseous buffer area 7 are arranged in the third accommodating cavity. In order to make the pressure on the two sides the same, the second containing cavity and the third containing cavity are the same in size.
The heat exchanger 2 comprises a plurality of parallel and evenly distributed heat exchange assemblies, each heat exchange assembly comprises a plurality of U-shaped pipes 21, an air return pipe 22, a plurality of heat exchange pipes 23 arranged in parallel and aluminum foils expanded on the heat exchange pipes 23, the heat exchange pipes 23 are connected with the U-shaped pipes 21 through the air return pipes 22, and the air return pipes 22 are arranged on one side of the right protection plate 14.
The left guard plate 13 and the right guard plate 14 are respectively provided with a through hole corresponding to the heat exchange tube 23, and the heat exchange tube 23 penetrates through the through holes.
In order to make the structure of the shell 1 more firm, the upper guard plate 11, the lower guard plate 12, the left guard plate 13 and the right guard plate 14 are fixed by welding.
In order to make the housing 1 less prone to rust, the upper guard plate 11, the lower guard plate 12, the left guard plate 13, and the right guard plate 14 are made of stainless steel.
In order to facilitate connection between the cold air channel 4 and the hot air channel 5 and ensure sealing performance, the cold air channel 4 is provided with a cold air inlet connecting port 41 and a cold air outlet connecting port 42. The hot air channel 5 is provided with a hot air inlet connector 51 and a hot air outlet connector 52.
The working principle is as follows: the heat exchanger 2 completes the circulation of the heat exchange medium by utilizing the characteristics that the heat exchange medium is gasified when meeting heat and is liquefied when meeting cold, so that cold air is arranged at the upper part of the heat exchanger 2, and the gaseous heat exchange medium is condensed into a liquid heat exchange medium after meeting the cold air and flows to the bottom of the heat exchanger 2, wherein a hot air channel 5 is arranged at the bottom of the heat exchanger 2; after encountering hot air, the liquid heat exchange medium absorbs heat and is gasified into a gaseous heat exchange medium, the gaseous heat exchange medium flows back to the upper part of the heat exchanger 2 through the air return pipe 22, and the gaseous heat exchange medium is liquefied again after releasing heat, so that the cold air channel 4 is arranged on the upper part of the heat exchanger 2.
If the cold air channel 4 completely occupies the upper part of the heat exchanger 2 or is close to the air return pipe 22, it cannot be ensured that the refrigerant liquefied by the cold air does not flow from the air return pipe 22 to the bottom of the heat exchanger 2, so that the flow of the gaseous heat exchange medium is influenced; similarly, for the hot air channel 5, if the liquid buffer 6 does not exist, it cannot be ensured that the heat exchange medium gasified by the hot air does not flow back to the upper part of the heat exchanger 2 from the left part of the heat exchanger 2, so that the flow of the liquid heat exchange medium is influenced.
Cold air and hot air enter the heat exchanger 2 from opposite directions, and the cold air and the hot air are separated by the partition plate 3, so that the pressure on two sides of the aluminum foil through which the cold air flows and the pressure on two sides of the aluminum foil through which the hot air flows are consistent, and after the aluminum foil is not used for a long time, the aluminum foil deforms due to the fact that pressure difference continuously exists on two sides, and therefore the pressure drop along the air duct is increased, the air quantity is reduced, and the heat.
In conclusion, the pressure on the two sides of the aluminum foil in the heat exchanger 2 is consistent, and the problems of large wind resistance, small flow and the like caused by deformation after long-time use are solved; and the heat exchange effect is good, and the service cycle is long.
It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
