A wine cabinet using a pulse-tube free-piston Stirling refrigerator

Abstract

The invention discloses a vessel type free piston Stirling refrigerator-adopted wine cabinet. The wine cabinet comprises a wine cabinet box and a refrigeration system, wherein the wine cabinet box isan internal refrigeration area surrounded by an external thermal insulation framework and a door; the refrigeration system is formed by a vessel type free piston Stirling refrigerator, a gravity assisted heat pipe cooling device, a cored heat pipe cold guiding device, a ring-shaped locking member and ring-shaped fasteners and is arranged at the inner top of the wine cabinet box; the gravity assisted heat pipe cooing device comprises a plurality of U-shaped gravity assisted heat pipes; evaporation ends of the gravity assisted heat pipes are tightly contacted and connected with a cooling surfaceof the Stirling refrigerator; first fins are arranged at condensation ends of the gravity assisted heat pipes; first fans are arranged outside the first fins; the cored heat pipe cold guiding devicecomprises a plurality of cored heat pipes; condensation ends of the cored heat pipes are connected with a cold head of the Stirling refrigerator through ring-shaped fasteners; second fins are arrangedat evaporation ends of the cored heat pipes; and second fans are arranged outside the second fins so as to carry out convective cooling on the second fins.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a wine cabinet adopting a pulse tube type free piston Stirling refrigerator. Background technique [0002] When storing all kinds of high-grade alcohol, in order to maintain its good quality, it needs to be stored in a certain environment. The environment for preserving wine requires constant temperature, constant humidity, light-proof, shock-absorbing, ventilation, and no peculiar smell. Wine cabinets can precisely control the environment in which wine is stored and prevent it from spoiling due to oxidation. [0003] At present, commercially available wine coolers generally use two refrigeration methods, thermoelectric refrigeration and vapor compression refrigeration. [0004] A wine cooler with thermoelectric refrigeration uses a thermoelectric cooler (TEC) as the main cooling source. The working principle of thermoelectric coolers is based on the second ther...

AI Technical Summary

Problems solved by technology

The sound work recovery problem of the pulse tube refrigerator is solved by setting a short room-temperature expansion piston at the hot end. Therefore, when the sound work at the cold end is fully recovered, the theoretical efficiency of the new pulse-tube free-piston Stirling refrigerator is Carnot cycle efficiency
