Description
Technical field
A kind of semiconductor refrigerating refrigerating box of the utility model relates to is refrigerating box a kind of semiconductor refrigerating, can interruptedly supplying power, that still can be incubated after having a power failure.Be applicable to the semiconductor refrigerating refrigerating box that needs to be interrupted refrigeration, need be specially adapted to the semiconductor refrigerating refrigerating box of energy efficient.
Background technology
Semiconductor cooling device is made up of two heat exchanger therebetween a slice semiconductor chilling plates at present.Cold-side heat exchanger places cool room, and hot-side heat exchanger places heat-dissipating space.Semiconductor cooler is by after the rated current, and the semiconductor chilling plate two ends produce the temperature difference, cold junction fin absorption refrigeration chamber heat, and the hot-side heat dissipation sheet cools cool room to the heat-dissipating space distribute heat.In case and semiconductor chilling plate cuts off the power supply, because semiconductor chilling plate is a good conductor, and the cool room temperature is lower than heat-dissipating space, reverse harmful heat exchange takes place in two heat-exchanger, be that reverse heat exchange takes place for cool room and heat-dissipating space, cause the cool room loss of refrigeration capacity, cool room effectively is incubated.Therefore existing equipment mostly needs continued power, has wasted the energy.
Summary of the invention
The purpose of this utility model is to provide a kind of semiconductor refrigerating refrigerating box at above-mentioned weak point, both can be interrupted energising by making semiconductor chilling plate under the continued power situation, guarantees that refrigerating box effectively is incubated, again can energy savings.Can also be when semiconductor chilling plate cut off the power supply, refrigerating box by the semiconductor chilling plate heat radiation, effectively is incubated refrigerating box.
A kind of semiconductor refrigerating refrigerating box of the utility model takes following technical scheme to realize: a kind of semiconductor refrigerating refrigerating box comprises refrigerating box, semiconductor chilling plate, cold-side heat exchanger, hot-side heat exchanger, heat-dissipating space, thermal resistent cover and thermal resistent cover controller, and refrigerating box comprises refrigerating box shell body, refrigerating box heat-insulation layer and refrigerating box inner housing; Semiconductor chilling plate is arranged in the refrigerating box heat-insulation layer, and cold-side heat exchanger is arranged in the refrigerating box, is close to semiconductor chilling plate one end; Hot-side heat exchanger is close to the semiconductor chilling plate other end, is in the heat-dissipating space; Thermal resistent cover is arranged in the refrigerating box, and the thermal resistent cover controller is housed on the thermal resistent cover, and thermal resistent cover is controlled by the thermal resistent cover controller, and thermal resistent cover covers on the cold-side heat exchanger or leaves cold-side heat exchanger.
Described thermal resistent cover controller can be anyly can control the device that thermal resistent cover is in two correct operating positions, as adopt Electromagnetic Drive pull bar, motor-driven pull bar or manual pull bar, be used to control thermal resistent cover and cover on the cold-side heat exchanger or leave cold-side heat exchanger.
Operation principle: during semiconductor chilling plate energising work, thermal resistent cover controller control thermal resistent cover is away from cold-side heat exchanger.This moment, semiconductor chilling plate made the refrigerating box cooling by cold-side heat exchanger, dispelled the heat to heat-dissipating space by hot-side heat exchanger.When the semiconductor chilling plate outage quit work, thermal resistent cover controller control thermal resistent cover covered cold-side heat exchanger.Because semiconductor chilling plate is a good conductor, reverse heat exchange takes place in cold-side heat exchanger and heat-dissipating space, final temperature and heat-dissipating space isothermal.And since this moment thermal resistent cover cover cold-side heat exchanger, refrigerating box and cold-side heat exchanger are no longer carried out heat exchange, and refrigerating box can effectively be incubated.
When described cold-side heat exchanger makes the refrigerating box cooling, can be (as the convection current) of nature, also can be compulsory (as using fan).
A kind of semiconductor refrigerating refrigerating box is simple in structure, reasonable in design, not only can when semiconductor chilling plate energising work refrigerating box effectively be lowered the temperature.And under the continued power situation, be interrupted energising by making semiconductor chilling plate, and can guarantee that refrigerating box effectively is incubated, again can energy savings.Can also be when semiconductor chilling plate cut off the power supply, refrigerating box by the semiconductor chilling plate heat radiation, effectively is incubated refrigerating box.
