Description

Circular air-water heat exchanger for household

The utility model relates to family expenses heat-obtaining utensil, particularly a kind of heat exchanger that utilizes heating system to obtain vapour, bath usefulness hot water.

Along with improving constantly of living standards of the people, family's warming is resolved gradually by central heating or family expenses soil heating installation, but the bathing in winter is mainly still to common plunge bath or approach such as coal gas heat-obtaining, electric heat-obtaining, above bathing approach exists inconvenient, high, the uneasy congruent shortcoming of expense, utilizes winter heating system to obtain bathing and remains to be developed with the technology of hot water.

The purpose of this utility model is by utilizing existing household heating system, a kind of household central heating hot water exchanger being provided, to solve the problem of present people bathing in winter inconvenience.

The purpose of this utility model solves by the following technical programs, the utility model is by circular water tank, the hot water inlet pipe, many group heat exchanging fins, hot water return pipe is formed, be connected by many group heat exchanging fins between hot water inlet pipe and the hot water return pipe, each group heat exchanging fin all advances at hot water, form a loop between the backwater, the width of every group of heat exchanging fin is all inequality, the width maximum of the heat exchanging fin by circular water tank diameter wherein, the width dimensions of all the other heat exchanging fins reduces gradually along water inlet pipe, the hot water inlet pipe is positioned at water tank upper, water tank is stretched out at its two ends, one end is a three-way interface, the upper outlet of the three-way interface case interface that rises for splashing, Horizontal Exit is the heating installation admission port, hot water inlet pipe's the other end is provided with exhaust outlet, hot water return pipe is positioned at the water tank bottom, one end is closed in the water tank, and the other end stretches out with heating system and is connected, and tank top is provided with cold water inlet, the bottom is provided with hot water outlet, and the water tank side is provided with the water level inspection socket.

For preventing the hot water exchanger heat radiation, heat-insulation layer can be set around water tank.

The water level inspection socket can be set to a gate valve, and its setting height(from bottom) is higher than the hot water inlet pipe.

The group number of many group heat exchanging fins can be 3,5,7 groups, and being that the center is symmetrical with the heat exchanging fin by circular water tank diameter during installation installs.

Heat exchanging fin can be welded by two stalloy fastenings that are pressed into flute profile.

The utility model can make full use of existing family expenses heating system and obtain bathing hot water, has convenience, safety, thermal efficiency advantages of higher.Experiment shows, when the water of heating system, temperature degree 〉=90 ℃, the water of 100kg is through 50 minutes heat-obtaining temperature 〉=85 ℃; The water of 120kg is through 60 minutes heat-obtaining temperature 〉=85 ℃; The water of 150kg is through 70 minutes heat-obtaining temperature 〉=85 ℃.
