It answers, the divider extends outward to form a bellows, and one end of the bellows is connected to heat exchange department, and the other end is connect by a pipe
Head is in communication with the outside.
Further, the pipe fitting is round tube, with a thickness of 0.06mm-1.5mm.
Further, the divider has extended downwardly connection strap, and the connection strap and the arc sealing strip are affixed, institute
It states arc sealing strip and is formed by plane lower than the plane where the divider, so that the arc sealing strip sinks to the heat
In exchange part.
Further, blower is provided in the bellows.
Further, the blower is the drawing-in type turbofan from the heat exchange core body to the pipe fitting.
Compared with the prior art, the advantages of the present invention are as follows:
1, when two kinds of air dielectric heat exchange operations, the gap of adjacent pipe sections channel partition is very small, and heat transfer effect is excellent, together
When, the present invention can adjust the size in gap by adjusting the size of pipe fitting, and it is very big to adjust space.
2, two kinds of air reverse flows of indoor and outdoor, heat transfer effect is best, two kinds of heat transferring mediums of the invention, complete reverse flow
It is dynamic, in certain special occasions, it is necessary to when can accomplish to exchange close to isothermal, scene heat exchange efficiency on probation improves 3 times or so, changes
The thermal efficiency has reached 98.8%.
3, built-in small sized turbine blower, round-the-clock running, less energy-consuming.
Below with reference to accompanying drawings, the present invention is described in further detail.

Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
As shown in Figure 1-Figure 3, the disclosure of the embodiment of the present invention a kind of new blower for heat recycling full counterflow heat exchange core, master
It is used for domestic small new blower for heat recycling, including heat exchange department 2 and the sealing element 1 for being mounted on 2 both ends of heat exchange department, heat to be handed over
Changing portion 2 includes multiple mutually nested pipe fittings 21, and in the present embodiment, pipe fitting 21 uses wall thickness for the thin-wall circular tube of 0.1mm thickness
(such as air-exhausting duct), under conditions of the guarantee the thin more is able to achieve equal heat exchanges, additionally it is possible to which guarantee has certain intensity and can
Processability.There is gap 22 to by indoor and outdoor air to be exchanged, sealing element 1 includes two separations between adjacent pipe fitting 21
Item 11 and multiple arcs sealing strip 12, in the present embodiment, two mutual angles of divider 11 are 90 °, and divider 11 is handed in heat
