ンｆの間隔ｌを等間隔としている（第３図参照）。This system adopts a configuration in which an air blowing fan a is provided in the upper part of the device, and an absorber b and a condenser c are vertically arranged and arranged on the left and right of the fan. Further, generally, the intervals l of the laterally projecting cooling fins f in the flow-down pipe parts that become the air-cooling heat exchanger parts d and e of the absorber and the condenser are made equal (see FIG. 3).

下部で性能が大きく異なる。<Problems to be solved by the invention> However, in such a type in which the cold air is sucked and flowed right above from the lateral direction, the flow velocity of the wind is inevitably high in the portion close to the fan, and it is far from the fan. The wind speed becomes slower in the lower part. Therefore, the performance is significantly different between the upper part and the lower part of the heat exchanger part.
本考案は上記実情に鑑み、空冷熱交換器部のフィンの配
列を部分的に異にし均一な熱交換を得る如くした空冷吸
収式冷凍機を提供することを目的としたものである。The present invention has been made in view of the above circumstances, and an object thereof is to provide an air-cooled absorption refrigerating machine in which fins of the air-cooling heat exchanger section are partially different so as to obtain uniform heat exchange.

る。<Means for Solving the Problems> The present invention is directed to an air-cooled absorption refrigerator having a cooling fan in the middle upper part of a vertical air heat exchanger section-equipped absorber and a condenser with air heat exchanger section, which face each other. The fin pitch of each air heat exchanger part close to the cooling fan is made dense, and the fin pitch of the part distant from the cooling fan is roughly set.

な流速を得るようになる。<Operation> Due to the above-mentioned configuration, when the absorption fan is operated, if the cooling fan arranged at the upper part of the equipment rotates, the negative pressure generated at the back of the absorption fan causes the vertical direction of the absorber and the condenser facing each other. From each of the air heat exchanger parts, the air is guided with a bent flow of a right-angled bend, and heat is exchanged in the air heat exchanger part by the passage of this wind. In this case, the fin group protruding from the air heat exchanger part has a denser part near the cooling fan to slightly slow down the air flow rate, and a lower part far from the cooling fan to roughen the air flow rate to increase the air flow rate as a whole in the vertical direction. A uniform flow velocity is obtained.

ものである。Reference numeral 1 denotes an absorber with a flow-down tube type air heat exchanger portion 4 in which a vertical fin 3 having an evaporator 2 disposed above is projecting, and a condenser 5 is provided at a position spaced apart from the absorber 1 by a predetermined distance. The cooling fin 7 is provided on the upper part of the condenser 5, and the low temperature regenerator 7 is provided on the upper end of the downward flow tube type air heat exchanger section 6
A cooling fan 8 is attached to an upper intermediate portion between the low temperature regenerator 7 and the evaporator 2, and a high temperature regenerator 9 is provided below the absorber 1 and the condenser 5 below, a burner 10 for heating the high temperature regenerator 9 and a high temperature heat exchanger. 11, a low temperature heat exchanger 12, an absorbing liquid pump 13 and the like are provided, and a pumping pipe 14 from the high temperature regenerator 9 is exposed to the low temperature regenerator 7 via the high temperature heat exchanger 11 to form a condenser. The refrigerant pipe 15 from 5 is led to the evaporator 2, and the dilute liquid pipe 16 from the absorber 1 is connected to the high temperature regenerator 9 via the pump 13, the low temperature heat exchanger 12 and the high temperature heat exchanger 11, and a predetermined refrigeration cycle To form a double-effect air-cooled absorption type refrigerator 17 as a whole. In this case, the density (pitch) of the fins 3 protruding from the air heat exchanger parts 4, 6 is set so that the upper position on the upper side of the cooling fan 8 is dense and the lower side of the cooling fan 8 is separated. Is coarse.

る。Next, this operation will be described. First, the refrigerant vapor generated in the high temperature regenerator 9 is guided to the low temperature regenerator 7, where it is reheated and liquefied in the refrigerant vapor condenser 5, and the refrigerant liquid is evaporated.
And the refrigerant is evaporated to cause a refrigerating effect, and the absorber 1 absorbs the refrigerant vapor to maintain the refrigerating capacity.

Since the portion close to is dense and the portion far is rough, the flow velocity of air that can occur in the portion close to the cooling fan 8 becomes slower,
The flow velocity of the air in the distant portion becomes fast, the flow velocity becomes uniform over the entire vertical width, and even in the upper and lower portions of the air heat exchanger units 4 and 6, average performance can be obtained.
