Abstract

Изобретение относитс к теплообменной технике и может быть использовано в энергетическом и химическом машиностроении. Его цель заключаетс в повышении эффективности теплообмена. При движении воздуха (В) он поперечно омывает трубы (Т) групп (Г) 4 и 5, по которым прокачиваетс охлаждающа вода. При движении В происходит интенсивна турбулизаци его потока по всей глубине пучка Т. Скрещивание Т в Г 4 и 5 позвол ет увеличить количество Т в каждой Г 4 и 5, т.е. максимально увеличить поверхность теплообмена. 1 з.п.ф-лы, 2 ил.The invention relates to heat exchange engineering and can be used in power and chemical engineering. Its purpose is to increase the efficiency of heat transfer. When air moves (B), it transversely flushes the pipes (T) of groups (D) 4 and 5 through which cooling water is pumped. When B moves, intense turbulization of its flow occurs throughout the entire depth of the beam T. Crossing T in G 4 and 5 allows increasing the number of T in each G 4 and 5, i.e. maximize heat transfer surface. 1 hp ff, 2 ill.

Claims

Claim

1. A heat exchanger comprising a cylindrical body and a cylindrical insert installed inside with a gap relative to it, in the cavity of which there are groups of pipes connected to the said gap, installed in each group parallel to each other, and in adjacent groups at an angle to each other, characterized in that, in order to increase the efficiency of heat transfer, in each group the pipes are located in the same plane, and in the groups through one pipe are installed in a checkerboard pattern, while the angle ce between the pipes in adjacent groups determines I dependence and = 180 ° - 2 arcsln <

where R is the inner radius of the insert;

and - the largest distance between the extreme pipe of the group and the inner surface of the insert.

2. The heat exchanger according to claim 1, with the fact that in the aforementioned gap guide baffles are installed, which are located radially on opposite sides of the insert.
