Abstract

PURPOSE:To promote heat exchange between air, passed by a fan motor, and miniaturize a fin condensor by an amount corresponding to the promotion of the heat exchange by a method wherein a pipe, connecting a compressor with a fin condensor, is fixed to the fixing plate of the fan motor. CONSTITUTION:High-temperature high-pressure refrigerant gas, discharged out of a compressor 2, is cooled by the air of a fan motor 5 upon passing through a pipe 10 coaked to the fixing plate 6' of the fan motor and is condensed in some degree while it is sent to a fin condensor 3. Acoordingly, the condenser can be miniaturized by an amount corresponding to the condensation whereby a condensing unit can be miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air-cooled condensing unit for cooling refrigerators and the like.

BACKGROUND OF THE INVENTION In recent years, there has been a strong demand for smaller condensers in the market. For example, the configuration shown in the condensing unit catalog published by Matsushita Electric Industrial Co., Ltd., published in April 1989, was common. A conventional condensing unit will be described below with reference to the drawings.

FIG. 3 is an enlarged sectional view of a main part of a conventional condensing unit, and FIG. 4 is a perspective view of the conventional condensing unit. In Figures 3 and 4, 1 is a unit pace, 2 is a compressor 3 is a fin condenser, and pipe 3 is a fin condenser.
a and fins 3b. A fan duct 4 partially covers the upper surface of the fin capacitor 3. 5 is a fan motor, 6 is a fan motor fixing plate, and 7 is a fan. 8 is a pipe provided between the compressor 2 and the fin condenser 3.

The operation of the condensing unit configured as described above will be explained below. When the condensing unit is operated, the refrigerant gas is compressed by the compressor 2 to become high temperature and high pressure refrigerant gas, which passes through the pipe 8 and flows through the pipe 3a of the fin condenser 3. On the other hand 7
As the unmotor 5 operates, the fan 7 rotates and air flows in the direction of the arrow. When air passes through the fin condenser 3, heat exchange occurs between the refrigerant flowing through the pipe 3a and the air, and the high temperature and high pressure refrigerant is cooled and condensed into liquid, and after passing through the fin condenser 3, it becomes a low temperature and high pressure refrigerant liquid. Otherwise, it is sent to a cooler (not shown) and returned to the compressor 2.

As above, cycles <9 are returned. The condensing unit has only the function of condensing the refrigerant of the above-mentioned cooling system. Usually, a condensing unit cooler is combined to form a cooling system □, which is used to cool a refrigerator or the like.

Problems to be Solved by the Invention However, with the above configuration, although the condensing capacity has been improved, the capacity of the fin condenser and 7 am motor must be increased when used under harsh conditions. ,
There were problems in that the condensing unit became larger and the power consumption increased.

In view of the above problems, the present invention provides a small-sized condensing unit that efficiently improves condensing capacity without increasing the size of the condensing unit or increasing power consumption.

Means for Solving the Problems In order to solve the above problems, the condensing unit of the present invention has a structure in which a cut-out is provided on the fan motor fixing plate to fix the pipe from the compressor to the fin condenser. be.

Effects According to the present invention, with the above-described configuration, when the high-temperature, high-pressure refrigerant gas discharged from the compressor passes through the pipe caulked to the fan motor fixing plate, it is cooled by the wind of the fan motor and sent to the fin condenser. Since the condensation is condensed to some extent by then, the condenser can be made smaller by that amount, and the condensing unit can be made smaller.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is an enlarged sectional view of a main part of a condensing unit in an embodiment of the present invention, showing the direction of air flow. FIG. 2 shows a perspective view of a condensing unit in an embodiment of the present invention. In FIGS. 1 and 2, components that are the same as those of the prior art are given the same reference numerals and detailed explanation thereof will be omitted.

A pipe 1o provided between the compressor 2 and the fin condenser 3 is extended from the pipe 8 of the conventional example, and is fixed by a cut-out 9 on the outer surface of the fan motor fixing plate 6'. In the above configuration, when the condensing unit is operated, the refrigerant flows from the compressor 2 through the pipe 1o to the pipe 3a of the fin condenser 3. The fan motor 5 is driven, the fan 7 rotates, and air flows in the direction of the arrow, passes through the fin condenser 3, and then flows into the pipe 1o fixed to the fan fixing plate 6'. Heat exchange is performed, heat exchange is performed, and the heat exchange performance of the refrigerant is improved.

As described above, the heat exchange of the high-temperature, high-pressure refrigerant gas discharged from the compressor 2 is promoted before it flows into the fin condenser 3, so that the condensing capacity is improved.

Since the fin capacitor 3 can be made smaller due to the improved capacity of the capacitor 14a, the entire condensing unit can also be made smaller.

Effects of the Invention As described above, the present invention is capable of fixing a pipe to the cut-out portion provided on the fan motor fixing plate, thereby promoting heat exchange with the air passing by the fan motor. Since the capacitor can be made smaller, condensing can be made smaller.
