Abstract

PURPOSE:To improve condensation capability by forming a flange part by folding back two faces of a unit base among four faces of the same and providing a cut protrusion to closely fix a pipe extending from a compressor to a fin condenser. CONSTITUTION:A unit base 1' is folded back along its two faces to make satisfactory an air flow along the lower surface thereof and includes a cut protrusion 8 in the lower surface thereof. Once a condensing unit is actuated, refrigerator passes through a pipe 7' from a compressor 2 and flows to a pipe 3a of a fin condenser 3. Thereupon, since the pipe 7' is caulked to the cut protrusion 8 formed in the unit base 1', heat exchange is performed between the unit base 1' and the pipe 7' closely. Further, since the unit base 1' is folded only along its two faces, the low space of the unit base 1' allows easy passage of air therethrough to improve heat exchange capability of the refrigerant. Thus, high temperature and high pressure refrigerant gas is promoted in its heat exchange until it enters the fin condenser 3 to yield a fin condenser improved in condensation capability.

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 FIGS. 3 and 4, 1 is a unit pace, 2 is a compressor, and 3 is a fin capacitor, which is composed of a pipe 3a and fins 3b. A fan duct 4 partially covers the upper surface of the fin capacitor 3. 6 is a fan motor; 6 is a fan. 7 is compressor 2. This is a pipe installed between three fin capacitors.

The operation of the condensing unit configured as described above will be described 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 7 and flows through the pipe 3a of the fin condenser 3. On the other hand, the fan 6 rotates due to the operation of the fan motor 6, 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. The air is then sent to a cooler (not shown) and returned to the compressor 2. The cycle repeats as above. The condensing unit is the above-mentioned cooling system that only has the function of condensing the refrigerant. Usually, a condensing unit and a cooler are combined to form a cooling system, and the cooling operation of a refrigerator or the like is performed.

Problems to be Solved by the Invention However, with the above configuration, the condensing capacity can be improved, but when used under harsh conditions, the fin capacitor must be made larger and the capacity of the fan motor must be increased. This resulted in problems such as an increase in the size of the condensing unit and an increase in power consumption.

In view of the above problems, the present invention provides a compact condensing unit that efficiently improves condensing capacity without increasing the size of the condensing unit and increasing power consumption.

Means for Solving the Problems In order to solve the above problems, the condancing unit of the present invention includes bending only 592 of the four sides of the unit pace to form a flange portion, and providing a cut and raised portion on the unit pace, The structure is such that the pipe from the compressor to the fin condenser is tightly fixed.

Effects of 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 at the unit pace, heat exchange is possible, and the condenser can be made smaller accordingly. This makes it possible to downsize the monitoring unit.

Examples Examples of the present invention will be described below with reference to FIGS. 1 and 2.

Embodiments of the present invention will be described below 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.

1' is a unit pace, which is bent on only two sides to improve the air flow on the lower surface, and has a raised cut 8 on the lower surface. A pipe 7' provided between the compressor 2 and the fin condenser is extended from the pipe 7 of the conventional example, and is closely fixed by a cut and raised portion 8 on the lower surface of the unit space 1'.

In the above configuration, when the condensing unit is operated, the refrigerant flows from the compressor 2 to 7'.
through the pipe 3a of the fin condenser 3°
flows to Since the pipe 7' is caulked and fixed to the cutout 8 provided in the unit space 1', the unit space 1' and the pipe 1 are brought into close contact with each other, and heat exchange is performed.

In addition, since the unit space 1' has only 1a bent on two sides, air can easily pass through the lower space of the unit space 1', improving the heat exchange performance of the refrigerant. .

As mentioned above, before the high temperature and high pressure refrigerant gas discharged from the compressor 2 flows into the fin condenser 3,
Since heat exchange is promoted, condensing capacity is improved. Since the fin condenser 3 can be made smaller due to the improved condensing ability, the entire condensing unit can also be made smaller.

Effects of the Invention As described above, the present invention can promote heat exchange by closely fixing the pipe to the cut and raised portion provided in the unit space, and the fin condenser can be made smaller accordingly, making it possible to reduce the size of the condensing unit. can be downsized.
