Description
Technical field
But the semiconductor cooler of a kind of interruptedly supplying power of the present invention relates to is semiconductor cooler a kind of semiconductor refrigerating, can interruptedly supplying power, that still can be incubated after having a power failure.Be applicable to the semiconductor freezer and the air-conditioning that need to be interrupted refrigeration, need be specially adapted to the semiconductor freezer and the air-conditioning 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
But the objective of the invention is to provide at above-mentioned weak point a kind of semiconductor cooler of interruptedly supplying power, this refrigerator both can effectively lower the temperature cool room when semiconductor chilling plate energising work.And under the continued power situation, be interrupted energising by making semiconductor chilling plate, and can guarantee that cool room effectively is incubated, again can energy savings.Can also be when semiconductor chilling plate cut off the power supply, cool room by the semiconductor chilling plate heat radiation, effectively is incubated cool room.
But the semiconductor cooler of a kind of interruptedly supplying power of the present invention takes following technical scheme to realize: but a kind of semiconductor cooler of interruptedly supplying power comprises cool room, heat-exchanging chamber, semiconductor chilling plate, cold-side heat exchanger, hot-side heat exchanger, kind of refrigeration cycle passage and heat exchange block device; Cool room comprises cool room shell body, cool room heat-insulation layer and cool room inner housing; Heat-exchanging chamber comprises heat-exchanging chamber shell body, heat-exchanging chamber heat-insulation layer and heat-exchanging chamber inner housing;
Semiconductor chilling plate is placed in the heat-exchanging chamber heat-insulation layer, cold-side heat exchanger is arranged in the heat-exchanging chamber, cold-side heat exchanger is close to semiconductor chilling plate one end, and hot-side heat exchanger is close to the semiconductor chilling plate other end, is in the outer heat-dissipating space of semiconductor chilling plate;
Heat-exchanging chamber and cool room are connected by the kind of refrigeration cycle passage, and the kind of refrigeration cycle passage is provided with the heat exchange block device.
Described hot-side heat exchanger and cold-side heat exchanger can adopt fin or radiating tube.
Described heat exchange block device is the device that any medium that can reduce or block heat-exchanging chamber and cool room carries out heat exchange, can adopt magnetic valve, check valve or valve plate.
Operation principle: but a kind of semiconductor cooler of interruptedly supplying power, during semiconductor chilling plate energising work, the heat exchange block device is opened, and this moment, semiconductor chilling plate made the heat-exchanging chamber cooling by cold-side heat exchanger, by hot-side heat exchanger heat-dissipating space heat radiation towards periphery.Because the heat exchange block device is opened, and heat-exchanging chamber and cool room carry out heat exchange by medium through the kind of refrigeration cycle passage, make the cool room cooling simultaneously.
When the hot-side heat exchanger temperature surpasses setting value or cool room reaches when establishing the temperature definite value and during the external power outage, semiconductor cooler quits work by supporting controller control outage, the heat exchange block device cuts out, because semiconductor chilling plate is a good conductor, reverse heat exchange takes place in heat-exchanging chamber and heat-dissipating space, final temperature and heat-dissipating space isothermal.And because heat exchange this moment block device cuts out, cool room and heat-exchanging chamber can effectively be incubated cool room no longer by the medium heat exchange.Therefore, but the present invention can realize interruptedly supplying power.
The medium that above-mentioned heat-exchanging chamber and cool room carry out heat exchange can be gaseous medium (as an atmosphere), also can be liquid medium (as water).
Above-mentioned medium can be (as the convection current) of nature when carrying out heat exchange, also can be compulsory (as water pump).
Above-mentioned medium is when carrying out heat exchange, and the flow trace of medium can be (as liquid in the pipeline or the gas) fixed, also can be (when using gas in heat-exchanging chamber and the cool room as medium) arbitrarily.
Advantage of the present invention: the present invention is simple in structure, reasonable in design, not only can when semiconductor chilling plate energising work cool room effectively be lowered the temperature.And under the continued power situation, because heat-exchanging chamber of the present invention and cool room are connected by the kind of refrigeration cycle passage, the kind of refrigeration cycle passage is provided with the heat exchange block device, is interrupted energising by making semiconductor chilling plate, can guarantee that cool room effectively is incubated, again can energy savings.Can also be when semiconductor chilling plate cut off the power supply, cool room by the semiconductor chilling plate heat radiation, effectively is incubated cool room.But the present invention can realize interruptedly supplying power.
