Abstract: PURPOSE:To obtain heat dissipating performance of a machine room without influence of installing conditions of a refrigerator by providing a compressor, an air inlet vent hole, an air flowout vent hole at the room in a lower part of the refrigerator, providing a shielding plate at a lower part of the front surface of the refrigerator, and providing an opening at part of the plate corresponding to the forward vent hole. CONSTITUTION:When a compressor is operated, a machine room reaches a high temperature to generate a natural convection, heated air of the room starts to flow from an air flowout vent hole 4, and a flow of the air flowing to the room is simultaneously generated. The flow of the room allows the air of an ambient temperature at a front surface of a refrigerator to pass an opening 2a of a shielding plate and efficiently flows from an air inlet vent hole 3 to the room. Thus, the heated air to be discharged from the hole 4 passes through a gap of a back surface of the refrigerator by a natural convection without flowing again from the hole 3 to the room by short-circuiting the gap of the back surface of the refrigerator and a gap between a bottom and a floor of the refrigerator and flows out from an upper part of a ceiling of the refrigerator to the front of the refrigerator.

Abstract: PURPOSE:To reduce the invading amount of the heat of a dewing preventing pipe into the case of a refrigerator and obtain efficient cooling effect, by a method wherein the inlet port and the outlet port of the dewing preventing pipe are arranged respectively so as to be positioned at the upper and lower positions of a transversal partition or the left-and-right positions of a lateral partition while the other part of the same pipe is formed by bending. CONSTITUTION:A dewing preventing pipe 11 enters from a transversal partition 5a and enters through a lateral partition 6b, then, is U-turned to penetrate through the transversal partition 5b and is run along the upper surface 20 of the main body 1 of a refrigerator. The heat of high-pressure refrigerant gas from a compressor 15 is dissipated in a condenser 16 and the gas is liquefied, then, flows into the dewing preventing pipe 11 positioned on the transversal partitioning 5a, however, there is only one dewing preventing pipe on the transversal partitionings 5a, 5b whereby the amount of heat, invading into the casing of the refrigerator through a forming member 14, becomes one half of the amount of dissipating heat when two of the dewing preventing pipes are arranged in parallel. Accordingly, thermal affection, affected into the case of the refrigerator, may be reduced to one half naturally and efficient cooling effect may be obtained.
