Embodiment approach 1

[0063] figure 1 It is a front view of the cooler with a defrosting heater according to Embodiment 1 of the present invention. figure 2 It is a side view of the cooler with a defrosting heater in the first embodiment. image 3 It is an enlarged side cross-sectional view of the defrosting heater peripheral portion of the cooler with the defrosting heater according to the first embodiment. Figure 4 It is an exploded perspective view of main parts showing the mounting structure of the defrosting heater of the cooler with the defrosting heater according to the first embodiment.

[0064] exist Figure 1 to Figure 4 Among them, the cooler 1 is mainly composed of a cooling pipe 2, a heat accumulator 3 and a fin 4, and the cooling pipe 2, the heat accumulator 3 and the fin 4 are respectively formed of aluminum material. The cooling pipe 2 is formed by bending an aluminum pipe in a meandering manner, and passes through a plurality of fins 4 . The cooling pipe 2 is alternately for...

Abstract

The invention relates to a cooler having a defrosting heater and an object storing device. The cooler with a defrosting heater of the invention has: a cooling pipe (2) flowing inside the refrigerant and a plurality of fins (4) through the cooling pipe (2) constitute the cooler (1); and effect so that the use of convection cooling (2) within the flow of refrigerant defrost heater configuration mode (5). Thus, to improve the efficiency of defrosting, defrosting can be greatly reduced power consumption at the time. In addition, cooler and reduces the amount of space heater defrost. Again, defrost heater can be inhibited in the surface temperature of a flammable refrigerant temperature below the ignition.

Description

technical field [0001] 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 [0002] 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, in terms of refrigerants in the refrigeration cycle, in order to cope with the ozone layer depletion and global warming 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 refrigerants. Switching to hydrocarbon refrigerants (hereinafter referred to as "HC refrigerants") such as isobutane (R600a) with a low global warming coefficient. [0003] Such HC refrigerants, such as isobutane, are flammable refrigerants, and therefore, when refrigerant...
