Problems solved by technology

[0026] However, even if the cooler 60 described in Patent Document 1 is installed in the refrigerator described in Patent Document 2, the Figure 18 In the structure, since the end plate 63 needs to be provided, it is impossible to shorten the distance between the cooler 60 and the defrosting heater 64
Therefore, with this structure, there is a problem that it is not suitable for accommodating inside a space with limited height

Abstract

The present invention relates to a cooler with a defrosting heater, and an object storage device. The cooler with the defrosting heater according to the invention comprises the following components: a cooler (1) which is composed of a cooling tube (2) with refrigerant flowing therein and a plurality of fins (4) that pass through the cooling tube (2); and the defrosting heater (5) which is configured with a mode that the refrigerant in the cooling tube (2) is caused to flow through a convection effect. Therefore, the defrosting efficiency is improved and the electrical power consumption in defrosting can be greatly reduced. Additionally, the space taken by the cooler and the defrosting heater can be reduced. Furthermore, the temperature of the defrosting heater can be suppressed to lower than an ignition temperature of the flammable refrigerant.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200810176339.1, the application date is November 20, 2008, and the invention title is "cooler with defrosting heater and article storage device". technical field [0002] The present invention relates to a cooler constituting a refrigerating cycle installed on a refrigerator etc., and particularly relates to a cooler with a defrosting heater and an article storage device. Background technique [0003] In recent years, with the strong demand for energy-saving refrigerators in the market, the power consumption of heaters with defrosting has also been re-evaluated. In addition, as for the refrigerant in the refrigeration cycle, in order to cope with the ozone layer depletion and global warming problems caused by freon gas, the use of hydrofluorocarbons (hydrofluorocarbon-HFC) used in the past is being promoted to use non-ozone-depleting and non-ozone-depleting refr...
