Abstract

The invention relates to a liquid-state heat exchanger, and particularly relates to a household heat-exchange water heater which takes heat supply type water heat or gas heat as a heat source, and belongs to a water heating device. The heat-exchange water heater comprises a plurality of tap water heat conduction pipes 1 which are connected and communicated with one another in series, tap water heat conduction pipe communicating pieces 2, steam heating pipes 3, internal pipe communicating pieces 4, internal circular chamfering end covers 6, air-release valves 8, inner-screw steam inlet connectors 9 and inner-screw tap water inlet connectors 11. The heat-exchange water heater is characterized in that the two ends of the plurality of tap water heat conduction pipes 1 are serially connected and communicated with the tap water heat conduction pipe communicating pieces 2, the internal pipe communicating pieces 4 and connecting pieces 5 in a welding manner so as to form a rectangle; the plurality of internal circular chamfering end covers 6 are welded at the two ends of the tap water heat conduction pipes 1; each two adjacent steam heating pipes 3 are fixedly connected with the internal pipe communicating pieces 4 in a mode that the inner walls of the pipes are welded; before the steam heating pipes 3 are fixedly connected with the internal pipe communicating pieces 4 in a welding manner, round holes are punched firstly, and subsequently, turnup round-hole bosses 17 are stretched to be fixedly connected with the internal pipe communicating pieces 4 in a welding manner.

Description

technical field

[0001] The present invention relates to a liquid heat exchanger, in particular to a household heating type water heater or steam heater as a heat source, which belongs to a water supply device. Background technique

[0002] Existing pipeline water heaters on the market are very popular, but the disadvantage is frequent water leakage failures at weld points. There is nowhere to apply the pressure to force the unevenness of the weld point to leak, which brings inconvenience to the user. Contents of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, to provide a heat source with a simple structure, to provide heating, to exchange cold water into hot water with a water exchange heater device, and then to take a bath, and to solve the problem of washing tableware and laundry in winter. water problem.
