Abstract
A kind of liquid nitrogen and semiconductor freezer, belong to art of refrigeration units, feature is provided with liquid nitrogen storage tank in one end of existing semiconductor freezer, the tank mouth of liquid nitrogen storage tank is by it being equipped with pipeline and the refrigeration case inner space of the first motor-driven valve, the blast pipe it being equipped with the second motor-driven valve is installed at the other end of refrigeration cabinets, power switch is connected with first, second motor-driven valve respectively, and temperature-controlled conditions configuration switch is connected with temperature sensor and semiconductor cooling device respectively.Advantage is that cooling rate is fast, and operating efficiency is high.
Description
Technical field
The invention belongs to art of refrigeration units, be specifically related to a kind of liquid nitrogen and semiconductor freezer.
Technical background
Along with improving constantly of expanding economy and people's living standard, more higher requirements are proposed to the storage of food, medicine, cosmetics etc., particularly the field such as military affairs, medical treatment, laboratory requires that refrigerator can fast-refrigerating more, and working stability is reliable, safety and environmental protection, energy-saving no-noise etc.The refrigerator used both at home and abroad at present all adopts semiconductor freezer, as shown in Figure 1, 2, is be provided with semiconductor cooling device in casing, realizes refrigeration requirement.Its shortcoming is that refrigerating efficiency is low, and temperature fall time is long, affects result of use, makes it develop and is placed restrictions on.
Summary of the invention
The object of the invention is to provide a kind of liquid nitrogen and semiconductor freezer, effectively can overcome the shortcoming that prior art exists.
The present invention realizes like this, as shown in Figure 3, it is provided with liquid nitrogen storage tank 8 in one end of existing semiconductor freezer, liquid nitrogen storage tank 8 upper can mouth is by pipeline 9 and casing 1 inner space, pipeline 9 is provided with the first motor-driven valve 10, be provided with the blast pipe 13 it being equipped with the second motor-driven valve 12 at the other end of casing 1, power switch 5 is connected with first, second motor-driven valve 10,12 respectively, and temperature-controlled conditions configuration switch 5 ' is connected with temperature sensor 7 and semiconductor cooling device 6 respectively.
Advantage of the present invention and good effect are by adopting liquid nitrogen refrigerating to make cooling rate accelerate, saving temperature fall time, improve refrigerating efficiency, be incubated, can save liquid nitrogen consumption, reduce costs by semiconductor refrigerating.
Accompanying drawing explanation
Fig. 1 is existing semiconductor freezer contour structures schematic diagram.
Fig. 2 is existing semiconductor freezer internal structure schematic diagram.
Fig. 3 is refrigerator internal structure schematic diagram of the present invention.
In figure: 1-casing, 2-chamber door, 3-handle, 4-control panel, 5-power switch, 5 '-temperature-controlled conditions configuration switch, 6-semiconductor cooling device, 7-temperature sensor, 8-liquid nitrogen storage tank, 9-pipeline 10-the first motor-driven valve, 11-nozzle 12-the second motor-driven valve, 13-blast pipe.
Detailed description of the invention
As shown in Figure 3, by needing article that are freezing or refrigeration to be placed in the chamber of casing 1, opening the power switch 5 on control panel 4, being needed the temperature value of setting by the input of temperature-controlled conditions configuration switch 5 '.Now, refrigerator is started working, first, second motor-driven valve 10,12 starts, liquid nitrogen in liquid nitrogen storage tank 8 to be sprayed in the chamber of casing 1 by nozzle 11 and gasifies, and the temperature inside the box is reduced rapidly, and carries out heat exchange with article, blast pipe 13 is outwards vented simultaneously, the temperature inside the box is also fed back to control system by the temperature sensor 7 installed in casing, when temperature reaches setting value in casing, controls first, second motor-driven valve and closes.Meanwhile, semiconductor cooling device 6 is opened, and maintains the temperature inside the box, until complete the task of setting.
