Abstract
The utility model discloses a semiconductor refrigerated liquid circulating heat radiating device which comprises a heat radiating pipe and a metal liquid storage container, wherein the heat end surface of a semiconductor refrigerated slice is appressed on the metal liquid storage container. An opening at the upper end of the metal liquid storage container is communicated with an inlet of the heat radiating pipe. An opening at the lower end of the metal liquid storage container is communicated with an outlet of the heat radiating pipe. A certain amount of low temperature medium is arranged in the metal liquid storage container. When the temperature of the heat end surface of the semiconductor refrigerated slice rises, the low temperature medium is heated, the low temperature medium is vaporized to enter the heat radiating pipe and heat of the heat end surface of the semiconductor refrigerated slice is taken away. In the heat radiating pipe, the low temperature medium is gradually liquefied to flow down following the reduction of temperature, the low temperature medium which is cooled flows into the metal liquid storage container from the opening at the lower end of the metal liquid storage container, the whole process does not need an electric pump, liquid can circulate to radiate heat and electrical energy is saved.
Description
Technical field:
The utility model relates to the semiconductor refrigeration radiating device, specifically refers to a kind of liquid circulation heat abstractor.
Background technology:
At present, the liquid circulation heat abstractor of semiconductor refrigerating will use electric pump power usually, and electric pump drives liquid circulation heat radiation, but the electric pump working time is long, and heating burns out easily, and then influences the work of conductor refrigeration sheet, and is therefore, very high to the quality requirement of electric pump; And consumed power is wanted in the electric pump driving.
Summary of the invention:
The purpose of this utility model is to provide a kind of electric pump that do not need just can allow the liquid circulation dispel the heat the liquid circulation heat abstractor of saves energy semiconductor refrigerating.
The purpose of this utility model is achieved like this, the liquid circulation heat abstractor of this semiconductor refrigerating, comprise radiating tube, metal storage liquid container, the hot junction face of conductor refrigeration sheet is close on the metal storage liquid container, metal storage liquid container upper end open is communicated with the inlet of radiating tube, metal storage liquid container lower ending opening is communicated with the outlet of radiating tube, in the metal storage liquid container a certain amount of cryogenic media is housed.
Because metal storage liquid container upper end open is communicated with the inlet of radiating tube, metal storage liquid container lower ending opening is communicated with the outlet of radiating tube, in the metal storage liquid container a certain amount of cryogenic media is housed, when the hot junction of conductor refrigeration sheet surface temperature rises, the heating cryogenic media, cryogenic media is vaporized, enter radiating tube, take away the hot junction face heat of conductor refrigeration sheet, in radiating tube, cryogenic media is along with temperature reduces gradually under the fluidized flow, and the cryogenic media of cooling flows into metal storage liquid container from metal storage liquid container lower ending opening, whole process does not need electric pump just can allow the liquid circulation dispel the heat, and has saved electric energy.
Description of drawings:
Fig. 1 is the liquid circulation construction for heat radiating device schematic diagram of semiconductor refrigerating
The specific embodiment:
With reference to figure 1, the liquid circulation heat abstractor of this semiconductor refrigerating, comprise radiating tube 2, metal storage liquid container 5, the hot junction face of conductor refrigeration sheet 4 is close on the storage liquid container 5, metal storage liquid container 5 upper end open 7 are communicated with the inlet of radiating tube 2, metal storage liquid container 5 lower ending openings 1 are communicated with the outlet of radiating tube 2, in the metal storage liquid container 5 a certain amount of cryogenic media 3 is housed, metal storage liquid container 5 internal upper parts leave space 8, when the hot junction of conductor refrigeration sheet 4 surface temperature rises, heat cryogenic media 3, cryogenic media is vaporized, be full of the cryogenic media 3 of vaporization in the space 8, have certain pressure, cryogenic media 3 enters radiating tube 2, takes away the hot junction face heat of conductor refrigeration sheet 4, cryogenic media 3 flows into metal storage liquid container 5 along with temperature reduces gradually under the fluidized flow from metal storage liquid container 5 lower ending openings 1 in radiating tube 2.
Described radiating tube 2 head portions 6 and horizontal plane angle [alpha]≤45 degree, angle [alpha] makes the liquid in the head portion 6 flow into radiating tube 2.
The heat radiation of radiating tube 2 can be in radiating tube 2 outside air cooling, the water-cooled modes of adopting.Metal storage liquid container 5 shell upper can have closed aperture, with the convenient cryogenic media 3 that replenishes.
The utility model can be widely used in refrigerator, air-conditioning.
