Cryogenic liquid in the heat exchanger tube 4 of condenser 1 flows downward from top, and damp-heat air flows from bottom to top.It is such processing be for
More efficiently carry out heat transfer process, but simultaneously it there is also improved space.
During this exchange, heat exchanging liquid in heat exchanger tube 4 during flowing downward constantly with it is wet
Hot-air carries out heat exchange, absorbs substantial amounts of heat；Meanwhile bottom heat exchanger tube 4 is more nearly the air inlet 8 of damp-heat air,
Both factors all cause situation of the temperature higher than the temperature of top heat exchanger tube 4 of the heat exchanger tube 4 of the bottom of condenser 1.So
The condensation effect that will result in condenser bottom significantly declines, so as to the condensation effect of overall reduction condenser.And due to
Bottom condensation effect is inadequate, and the condensed water that a part condenses out from top can on the contrary can not arrange from condensed water outlet mouth 2
Go out, but the damp-heat air being stirred is blown back into washing machine again, reduces the drying efficiency of clothes washer/dryer.

The heat exchange tube design of the present embodiment is taken, equivalent to the external diameter and internal diameter for making each row heat exchanger tube from descending to up same
Step is gradually reduced, and so not only adds the internal diameter of bottom heat exchanger tube 4, so as to add bottom heat transferring medium and heat transfer tube wall
Heat exchange area, also add the heat exchange pipe external surface heat exchange area of bottom heat exchanger tube 4 simultaneously.And then enhancing bottom heat exchange
The purpose of the heat exchange efficiency of pipe 4, avoid to a greater extent it is above-mentioned due to bottom exchange capability of heat not enough and caused by under condensation efficiency
The drawbacks of drop.Raising clothes washer/dryer condenser condensation effect has been finally reached, has improved the target of clothes washer/dryer drying efficiency.At this
Why need to keep the gap between the two adjacent rings of the cylindrical spring shape heat exchanger tube of heat exchanger tube 4 to consolidate in embodiment and embodiment 3
Determine rather than take the constant mode of pitch, primarily to ensureing that the damp-heat air that bottom is blown into can be swimmingly in condenser
Interior flowing, it is avoided to pursue bottom condensation efficiency and bottom inflow resistance caused by reducing the gap of heat exchanger tube 4 is excessive, on the contrary shadow
The problem of ringing heat exchange efficiency.
Certainly by changing the internal diameter size distribution of heat exchanger tube 4, reach and change cooling medium and heat transfer tube wall in heat exchanger tube 4
Heat exchange area distribution method, equally can also simultaneously be applied in more application situations, be repeated no more here.
