风冷冰箱除霜专利技术综述

A Review of Patent about Air-Cooled Refrigerator Defrosting Technology

随着科技不断发展和人们生活水平的不断提高,人们对食物的储藏提出了更高的要求,冰箱被广泛应用于对食物的冷藏、冷冻。然而,蒸发器结霜问题是冰箱运行过程不可避免的,结霜会导致流通阻力增大,同时也导致换热热阻增加,降低了蒸发器的传热性能,进而影响整个冰箱的制冷性能。为了维持机组继续稳定运行,必须进行除霜。本文从专利的角度出发,分析了风冷冰箱专利的申请的申请人、国家/地区、年代分布情况以及技术演进历史,有助该技术的推广应用及技术的改进。

With the development of the GDP and the living standard,people are increasingly concerned about the storage of food,refrigerators are widely used to control the storage temperature.However,the surface of the evaporator is inevitable to frost formation when the refrigerator works.As a result,the frost layer leads to decrease in the heat transfer and an increase in wind resistance,which in turn affects the performance of the refrigerator.In this paper,the development,global distribution and the application of the patent about air-cooled refrigerator defrosting technology are reviewed,which facilitates the application and promotion of the technology.
