Abstract

PROBLEM TO BE SOLVED: To improve the efficiency of heat exchange, by forming an auxiliary suction path which distributes the flow of suction outside air that is formed by a through hole, a vent hole, etc., to the upper and lower locations of a heat exchanger approximately uniformly. SOLUTION: A strut 1a which is opposed to a windbreak plate 1c' is provided with a through hole 1b, and the rear part of a partitioning plate 1c is provided with a vent hole 1d which faces to the lower part of an auxiliary heat exchanger 4b. An auxiliary suction path B which connects the through hole 1b and the vent hole 1d is formed, and in this construction, the outside air can be sucked from the same auxiliary suction path B and a suction opening. Thereby, the increase in the wind velocity of the location close to a fan 5 is prevented, and the amount of suction air which passes through the upper and lower locations of the heat exchanger 4a and the auxiliary heat exchanger 4b is distributed approximately uniformly. The structure which prevents the decline in the efficiency of heat exchange is realized. By providing two or more through holes 1b, the amount of suction air which passes through the upper and lower locations of the heat exchanger 4a and the auxiliary heat exchanger 4b can be distributed more uniformly.

2. Description of the Related Art As shown in FIG. 2, for example, an outdoor unit of a conventional top-blowing type air conditioner has a bottom plate 2 on which a compressor (not shown) is mounted and at least a front surface on the bottom plate 2. A support column 1a standing on both sides, a horizontal partition plate 1c for partitioning the upper and lower portions on the bottom plate 2 into a blower chamber and a compressor chamber in which the compressor (not shown) is arranged, An air outlet 3 is provided at the upper part of the main body 1 consisting of a wind shield plate 1c 'hanging from the rear end of the air blower 1c, suction ports are provided at the front and rear of the lower part, and the blower 5 having the air outlet 3 facing the blower room is provided. A heat exchanger 4a with the suction port facing the rear of the wind shield plate 1c 'is provided upright, and the auxiliary heat with the rear portion inclined downward with the suction port facing the upper part of the partition plate 1c. The configuration was such that the exchanger 4b was arranged.

However, when the blower 5 is activated to suck outside air from the suction port, at a position close to the blower 5, the heat exchanger 4a and the auxiliary heat exchanger 4b are indicated by arrows a '. As the wind speed passing through each of the upper portions increases, the amount of suction air at the location increases, and accordingly, the amount of suction air at the lower portion indicated by the arrow b ′ decreases, and the suction air exchanges heat with the heat. Since the heat exchanger 4a and the auxiliary heat exchanger 4b cannot pass evenly, there is a problem that the heat exchange efficiency is reduced.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1A to 1C
In the above, 1 is an outdoor unit body of an air conditioner of a top blowing type,
Reference numeral 2 denotes a bottom plate on which a compressor (not shown) or the like is mounted, 1a denotes a column provided with a plurality of through holes 1b on at least both sides of the front surface of the bottom plate 2, and 1c denotes upper and lower portions of the column 1a. A horizontal partition plate 1c 'is divided into a blower room and a compressor room in which the compressor (not shown) is disposed, 1c' is a wind shield plate hanging down from a rear end of the partition plate 1c, and 3 is a main body 1 of the main body 1. The outlet is provided at the upper part, and the inlet is provided at the front and rear of the lower part. 4a is a heat exchanger standing upright with the suction port facing the rear part of the wind shield plate, and 4b is an auxiliary heat exchanger with the rear part inclined downward with the suction port facing the upper part of the partition plate 1c. A blower 5 is provided with the blower outlet 3 facing the blower room.

The pillar 1a facing the wind shield plate 1c 'is provided with the through hole 1b, and a rear portion of the partition plate 1c is provided with a vent hole 1d facing the lower part of the auxiliary heat exchanger 4b. An auxiliary suction passage B connecting the through hole 1b and the ventilation hole 1d is formed so that outside air is sucked from the auxiliary suction passage B and the suction port. As shown by arrows a and b, the wind speed at a position close to the blower 5 does not increase, and the amount of suction air passing through the upper and lower positions of the heat exchanger 4a and the auxiliary heat exchanger 4b is reduced. The structure is such that the heat is exchanged almost uniformly so that the heat exchange efficiency is not reduced.

Further, by providing a plurality of through holes 1b as shown in FIG. 1 (A), the amount of suction air passing through the upper and lower positions of the heat exchanger 4a and the auxiliary heat exchanger 4b is more uniform. And the heat exchange efficiency does not decrease.

The support 1a located above the partition plate 1c is provided with an auxiliary through hole 1b 'facing the lower part on both sides of the auxiliary heat exchanger 4b.
Suction air flows from the auxiliary through hole 1b 'to the auxiliary heat exchanger.
Since the air flows toward the lower part on both sides of the auxiliary heat exchanger 4b, the amount of intake air passing through the upper and lower positions of the auxiliary heat exchanger 4b is more evenly distributed, so that the heat exchange efficiency is not reduced.

Further, as shown in FIG. 1 (B), a plurality of the ventilation holes 1d are provided so that the lower part of the auxiliary heat exchanger 4b faces substantially uniformly. Air can be more uniformly delivered from the auxiliary suction passage B toward the lower part of the auxiliary heat exchanger 4b, and passes through the upper and lower positions of the auxiliary heat exchanger 4b in the same manner as described above. As a result, the amount of suction air passing through the upper and lower positions of the heat exchanger 4a is more evenly distributed, and thus the heat exchange becomes more uniform. The structure is such that the efficiency is not reduced.

With the above configuration, FIGS.
As shown in (C), the support 1a facing the wind shield 1c 'is provided with the through-hole 1b, and the rear of the partition 1c faces the lower part of the auxiliary heat exchanger 4b. Air holes 1d are provided, and an auxiliary suction passage B connecting the through holes 1b and the ventilation holes 1d is formed. The wind speed does not increase, and the amount of intake air passing through the upper and lower positions of the heat exchanger 4a and the auxiliary heat exchanger 4b is distributed almost uniformly, so that the heat exchange efficiency does not decrease. It will be an outdoor unit of a top-blowing type air conditioner.

[0015]

As described above, according to the present invention, an auxiliary air intake passage is formed which distributes the intake air almost equally above and below the heat exchanger, thereby improving the heat exchange efficiency. It becomes an outdoor unit of an air conditioner.
