The semiconductor dehumidification module 20 has a first end 21 and a second end 22, the first end 21 is located in the constant temperature and humidity space 12, the second end 22 is located outside the box 11, when the temperature of the first end 21 is lower than the temperature of the constant temperature and humidity space 12, when the air in the constant temperature and humidity space 12 flows through the first end 21, water drops or ice pieces are formed at the first end 21 and are separated out, and the dehumidification purpose is further achieved.
Further, the semiconductor dehumidification module 20 further includes a third fan 23, and the third fan 23 is close to the second end 22 for accelerating the air flow at the second end 22. Taking the first end 21 as the cooling end and the second end 22 as the heating end as an example, the third fan 23 will accelerate the heat dissipation of the second end 22, thereby improving the heat dissipation effect and further contributing to the improvement of the working efficiency of the semiconductor dehumidification module 20.
Referring to fig. 2, the wheel dehumidification module 30 includes a wheel 31 and a heating and blowing assembly 32. A part of the rotating wheel 31 is positioned in the constant humidity and constant humidity space 12, and the part forms an air adsorption area P1, so that the humid air in the constant temperature and constant humidity space 12 can be taken out to the outer side of the box body 11; another portion of the runner 31 is located outside the casing 11, which portion will form an air regeneration zone P2. The heating and blowing unit 32 is located outside the cabinet 11, and blows high-temperature, dry air toward the air regeneration region P2. The dehumidification process of the wheel dehumidification module 30 is as follows: the air adsorbing area P1 of the rotating wheel 31 blows the humid air in the constant temperature and humidity space 12 to the outside of the cabinet 11 along with the rotation of the rotating wheel 31, and at this time, the heating and blowing assembly 32 blows high temperature and dry air to the rotating wheel 31 (i.e. the air regenerating area P2) located outside the cabinet 11, so that the moisture in the humid air taken out by the rotating wheel 31 is dried and evaporated, and thus, the humid air in the constant temperature and humidity space 12 is continuously taken out of the cabinet 11 and dried and evaporated along with the continuous rotation of the rotating wheel 31, thereby achieving the purpose of dehumidification.
As described in the background art, the dehumidification process of the semiconductor dehumidification module 20 is intermittent, and the dehumidification process of the rotary dehumidification module 30 is continuous, the semiconductor dehumidification module 20 and the rotary dehumidification module 30 are combined, so that the dehumidification efficiency of the constant temperature and constant humidity box 10 can be effectively improved, and the dehumidification modules are simple in structure, independent and convenient to use.
Further, the rotating wheels 31 are coated with a water absorbing medium (not shown), when part of the rotating wheels 31 rotate to the inside of the constant-temperature and constant-humidity space 12, the water absorbing medium will absorb moisture in the humid air in the constant-temperature and constant-humidity space 12, and with the rotation of the rotating wheels 31, the part of the rotating wheels (i.e. the air absorption area P1) absorbing moisture will rotate to the outside of the box 11, at this time, the heating and blowing assembly 32 will blow high-temperature and dry air onto the part of the rotating wheels (i.e. the air regeneration area P2) absorbing moisture, so as to dry and evaporate the moisture on the air regeneration area P2, and thus, the circulation is continued, and the water absorbing medium will continuously absorb the moisture in the constant-temperature and constant-humidity space 12, thereby increasing the efficiency and achieving the purpose of.
The water-absorbing medium is preferably silica gel or a molecular sieve having a honeycomb-like adsorption structure.
Further, with continued reference to fig. 2, the heating and blowing assembly 32 includes a first fan 321, a filter 322, and a heater 323, and the air blown by the first fan 321 flows to the runner 31 through the filter 322 and the heater 323, and specifically flows to the air regeneration air region P2. The filter 322 filters the air, and the heater 323 heats the air, so as to obtain clean, high-temperature and dry air, improve the evaporation of moisture in the air regeneration area P2, and ensure the cleanliness of the air flowing into the constant-temperature and constant-humidity space 12 through the rotating wheel 31.
The heater 323 is preferably a heating wire, and has a simple structure and is convenient to use.
Further, the rotating wheel dehumidification module 30 further includes a second fan 33, and the second fan 33 is located in the constant temperature and humidity space 12 and is used for accelerating the air flow in the constant temperature and humidity space 12, which is helpful for improving the dehumidification efficiency.
In any of the above embodiments, the semiconductor dehumidification module 20 and the wheel dehumidification module 30 operate simultaneously, and the combination of the two effectively improves the dehumidification efficiency of the constant humidity chamber 10.
Further, when constant temperature and humidity case 10 was in the high temperature and high humidity operating mode, the temperature of first end 21 was higher than the temperature in constant temperature and humidity space 12, the aim at that sets up like this, because semiconductor dehumidification module 20 and external heat conductivility will be far higher than the foaming layer of box 11, so when constant temperature and humidity case 10 was in the high temperature and high humidity operating mode, semiconductor dehumidification module 20 was because of having the heat exchange with the external world, the temperature that leads to first end 21 will be less than the temperature in constant temperature and humidity space 12, and then produced the passive dehumidification phenomenon, and this is carried on the back with the operating mode of high humidity, will influence the operating efficiency of constant temperature and humidity case 10. Therefore, when the constant temperature and humidity box 10 is in a high temperature and high humidity condition, the temperature of the first end 21 is set to be higher than the temperature of the constant temperature and humidity space 12, so that the phenomenon of passive dehumidification caused by the fact that the temperature of the first end 21 is lower than the temperature of the constant temperature and humidity space 12 can be avoided. Meanwhile, the temperature of the first end 21 is higher, which is helpful for increasing the temperature in the constant temperature and humidity space 12 and increasing the heating efficiency of the constant temperature and humidity chamber 10.
In any of the above embodiments, when the constant temperature and humidity box 10 is under the high temperature and high humidity condition or the low temperature and low humidity condition, the semiconductor dehumidification module 20 is closed, and the rotary dehumidification module 30 is opened, so that the humidity requirement of the constant temperature and humidity box 10 can be met only by the rotary dehumidification module 30 under two conditions, and meanwhile, the adverse effect of the semiconductor dehumidification module 20 possibly brought under two conditions can be avoided, and the overall efficiency is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
