In other embodiments, settable two heat-conducting plate 20, two cooling chip devices 30 and two thermal insulation boards 40, two heat-conducting plates
20 can stick on wantonly two lateral surface of ontology 10 respectively, and two cooling chip devices 30 are separately positioned on two heat-conducting plates 20, two every
Hot plate 40 is similarly separately positioned on two heat-conducting plates 20, reaches more contacts area, promotes temperature control efficiency, according to this class
It pushes away, the quantity of heat-conducting plate 20, cooling chip device 30 and thermal insulation board 40 can be increased and decreased according to user's demand.
Working principle of the invention is as follows: refering to Figure 1, the present invention is in use, cooling chip 32 can be switched to heat dissipation
Or warming mode, when for radiating mode, cooling chip 32 towards heat-conducting plate 20 one side be cold end, then heat-conducting plate 20 by
The heat absorption of cold end and temperature declines so that water temperature drop, but the another side of cooling chip 32 is hot end and generates heat, the heat
Heat source is scattered and disappeared in air by radiating seat 31 in source；It otherwise is warming mode, the one side of cooling chip 32 towards heat-conducting plate 20 causes
Heat, then the another side of cooling chip 32 is cold end；It can reach and quickly control water temperature using cooling chip 32, be maintained at water temperature
Temperature purpose set by user.
It, can be easier since the heat-conducting plate 20 using large area is as the medium of heat transmitting in aforementioned process
Water temperature is maintained, also can achieve the purpose compared with power saving；And the wherein wall surface that heat-conducting plate 20 is set as ontology 10 more can reach
The water heating or cooling of direct internal volume, promote overall operation efficiency.
In aforementioned process, since radiating seat 31 is equipped with the design of deflector 50 and fan 60, can quickly by
Heat partition caused by cooling chip 32 is to fin 312, then is blown into wind by fan 60 and is led wind direction both ends through deflector 50
Out, uniformly the heat on fin 312 is taken away, promotes overall operation efficiency.
It, can be faster by refrigeration due to having the first heat pipe 33 and the second heat pipe 34 in aforementioned process
Heat caused by chip 32 cold is transmitted to heat-conducting plate 20 and radiating seat 31.
In aforementioned process, due to the design with thermal insulation board 40, the face that heat-conducting plate 20 is contacted with air can be reduced
Product, so that the heat loss of the be transmitted to heat-conducting plate 20 of cooling chip 32.
The above is only presently preferred embodiments of the present invention and, and it cannot be said that specific implementation of the invention is confined to this
A little explanations, for those of ordinary skill in the art to which the present invention belongs, without departing from the inventive concept of the premise, also
Several simple deduction or replace can be made, all shall be regarded as belonging to protection scope of the present invention.
