Concrete meaning in the present invention.
Embodiment, referring to figs. 1 to Figure 12.
It is as shown in Figure 1 heat pump drying system, including water recycle heat exchanger 400.In water recycle heat exchanger 400
Including aqueous medium circulation path and air dielectric circulation path, water recycle heat exchanger 400 is for realizing by the heat of aqueous medium
Pass to air dielectric.The specific structure of water recycle heat exchanger 400 uses the prior art.
It is illustrated in figure 2 heat exchanger group 500.Heat exchanger group 500 is for realizing by the heat transfer of Freon medium
To air dielectric.Heat exchanger group 500 includes at least one switch room 501, and the top of switch room 501 is provided with freon outlet
502 and multiple exchange air intake vents 503, the bottom end of switch room 501 be provided with freon entrance 504 and multiple exchange air outlets 505；

The inner sidewall of room 501 is provided with multiple vertical hollow pipelines, roof of the top of multiple vertical hollow pipelines with switch room 501
Interval setting, the bottom end of multiple vertical hollow pipelines are arranged with the bottom wall interval of switch room 501, and multiple vertical hollow pipelines pass through
Wear multiple heat sinks 506.When air dielectric amount of flow is larger, partial air medium can be passed through out of vertical hollow pipeline.
Although the time of contact of extension air dielectric and heat sink 506 can be improved the heat absorption efficiency of air dielectric,
Overlong time then will affect whole working efficiency, and therefore, the middle part of switch room 501 is also horizontally arranged with mounting plate, mounting plate
It is provided with multiple drawing fans 507.It guides air dielectric to sequentially pass through heat sink 506 by drawing fan 507, accelerates work effect
The heat absorption efficiency of air dielectric is improved while rate.
As shown in figure 3, the set-up mode of switch room 501 has two according to the set-up mode of mounting plate and drawing fan 507
Kind.One kind is achieved in that, a switch room 501 is arranged, when the switch room 501 is sufficiently large, in order to realize that air dielectric is suitable
Benefit circulation, is arranged multiple mounting plates and drawing fan 507 in the switch room 501.Another implementation is then to be arranged multiple
Switch room 501 suitably reduces the volume of each switch room 501, setting installation and air-breathing wind between two neighboring switch room 501
Fan 507, realizes the circulation of air dielectric between multiple switch rooms 501.Second of implementation, for example, the setting of switch room 501 two
It is a, respectively first order heat exchanger 508 and second level heat exchanger 509, first order heat exchanger 508 and second level heat exchange
Drawing fan 507 is provided between device 509, the air in first order heat exchanger 508 can be sucked second by drawing fan 507
In heat exchanger.
