The specific embodiment
Referring to Fig. 1, parts such as the digital refrigerator Switching Power Supply 1 of two-door envelope fin heat pipe type thermocouple refrigeration commercial affairs, bridge chip fin heat pipe radiator 2, turnover fan shroud 3, cooling fan 4, thermocouple refrigeration device 5, heat insulation location and installation part 6, cool guiding block 7, cooler 8, cold scattering blower fan 9, inner blower cover 10, digital temperature control 11, casing 12, band iron 13, Air Filter 14, door-plate 15, the two-door strip of paper used for sealing 16 of magnetic, hinge 17 and three-position switch 18 are formed.
Referring to Fig. 1-Fig. 4, cooling fan 4 is installed on the bridge chip fin radiator 2 with turnover fan shroud 3, digital temperature control 11 provides the temperature inside the box data control system work energy-saving run, wherein the hot junction face of thermocouple refrigeration device 5 is close to bridge chip fin radiator 2 bottom end opening planes and is contacted, thermocouple refrigeration device 5 cold junctions are close to cool guiding block 7 one end faces and are contacted, and cool guiding block 7 other ends are close to cooler 8 planes and are contacted.Cold scattering blower fan 9 is installed on the cooler 8 and cooperates installation with inner blower cover 10 again.Cooling fan 4 is installed on the bridge chip fin heat pipe radiator 2, cooperates installation with turnover fan shroud 3, and inboard air inlet is equipped with Air Filter 14, and the following square hole of turnover fan shroud 3 is installed three-position switch 18.Digital temperature control 11 is installed on the square hole of turnover fan shroud 3, and its temp probe is installed in the air inlet inboard of cool guiding block 7 tops, inner blower cover 10.
The utility model has reduced the temperature inside the box cold draining owing to adopted the two-door strip of paper used for sealing 16 of magnetic, owing to adopted bridge chip fin radiator 2, has reduced to greater strength the hot-side temperature of thermocouple refrigeration device 5.The utilization of heat insulation location and installation part 6, cooler 8, case inner blower improved thermocouple refrigeration device 5 cold junction temperatures loose from.Alignment pin is equipped with in turnover fan shroud 3 upper ends, has prevented the air-out blocking, and the design of oblique arc hole is adopted in both sides, and having prevented that the single face air intake is obstructed influences performance.Above-mentioned several measures have increased the actual refrigeratory capacity of thermocouple refrigeration device, have also ensured the characteristics such as reliable of performance.
During work, after Switching Power Supply 1 was connected power supply, three-position switch 18 pushed the refrigeration position, and direct current is by thermocouple refrigeration device 5, and thermocouple refrigeration device 5 hot junctions generate heat, the cold junction refrigeration; The hot junction heat heating of the thermocouple refrigeration device 5 bridge chip fin heat pipe radiator 2 interior working medium of closely contact is with it absorbed heat and boiling, be evaporated to the working substance steam of certain pressure and heat, in heat pipe, rise rapidly thereupon, and in uphill process, heat is delivered on the bridge chip radiating fin by tube wall; Distinguished and admirable taking in the environment compeled in the cooling fan semi-finals, realized the heat radiation to thermocouple refrigeration device 5 hot junctions.The working substance steam that loses heat is condensed into worker quality liquid, relies on gravity along tube wall backflow working medium box, moves in circles to have realized heat radiation to thermocouple refrigeration device 5 hot junctions.The cold of thermocouple refrigeration device 5 cold junctions is delivered to cool guiding block 7, cooler 8 successively simultaneously, and through forcing of cold scattering blower fan 9 is distinguished and admirable cold is loose from case, has realized inner refrigeration.Three-position switch 18 pushes and heats the position, and direct current is oppositely imported, and can heat carrying out in the case.
Because this novel employing bridge chip fin heat pipe radiator has strengthened fin area of dissipation and ventilation effect, the more effective heat dispersion that improved.Adopt the sealing strip of the two air bags of magnetic, reduced cold draining more.Adopted Air Filter 14, bridge chip fin heat pipe radiator 2 surfaces are kept clean and heat dispersion for a long time, also made the characteristics that the utlity model has performance steady in a long-term.
