Abstract
The utility model relates to a domestic pressure bearing warm air water heater which is composed of a hot water tank and heat exchange tubes arranged in the hot water tank, wherein two or more than two heat exchange tubes form a heat exchanger, and the heat exchanger is vertically arranged between a water inlet tube and a water outlet tube of the hot water tank. Cold water and hot water in the hot water tank of the utility model convect quickly, so heat exchange rate can be increased. The hot water tank adopts a pressure bearing closed tank body and is provided with a heat insulation layer to insulate heat for a long time.
Description
Technical field
The utility model relates to a kind of home-use pressure-bearing water heater in central heating.
Technical background
Water heater in central heating has become the durable consumer goods of family's hot water in winter supply, and its operation principle is to utilize the heat of heating system hot water to pass through the heat-transfer surface of water heater the running water heat exchange.
Water heater is of a great variety in the market, and quality is very different.Its version adopts heat-exchange tube to turn to ￠ 8 copper pipes for being located in the radiator more, crosses running water in the copper pipe, and copper pipe is outward a heating installation water.Its advantage is: discharge pressure is big, and heat exchange is fast.Its shortcoming is; Because tap water quality difference copper pipe easily stops up; Second is that heating installation stops then can not go out hot water (can not be incubated); Three, because the heating installation water yield is little, then be only applicable to forced circulation system.
Summary of the invention
The home-use pressure-bearing water heater in central heating that technical problem to be solved in the utility model provides a kind of thermal efficiency height, can be incubated for a long time, do not stop up, discharge pressure is big.
The technical solution of the utility model is: the utility model is made of a boiler and the heat-exchange tube that is arranged in the boiler, and the heat-exchange tube more than two or two constitutes heat exchanger, and heat exchanger vertically is arranged between the water inlet pipe and water outlet pipe of boiler.
The utility model boiler is airtight round barrel shape casing.
The utility model adds heat-insulation layer outside boiler.
Good effect of the present utility model is as follows: the utility model is owing to adopt the drum casing as boiler, so it is difficult for stopping up, the heat exchanger that the utility model heat-exchange tube constitutes vertically is arranged between the water inlet pipe and water outlet pipe of boiler, the hot and cold water convection current is fast in the boiler like this, can improve the thermal efficiency, boiler installs the effect that heat-insulation layer plays insulation outward additional, and the utility model boiler is the airtight casing of pressure-bearing, so its discharge pressure is big, can satisfy the requirement of bathing.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model cross-sectional view.
The specific embodiment
Shown in accompanying drawing 1,2, the utility model boiler 1 is the round barrel shape casing, also can be rectangular shape casing, its water inlet pipe 3 and outlet pipe 4 that is located at boiler 1 side is vertical arrangement with the heat exchanger that the heat-exchange tube 2 that is located in the boiler 1 constitutes, be convenient to the hot and cold water convection current in the boiler 1 like this, improve the thermal efficiency.The airtight casing that the utility model boiler 1 adopts pressure-bearing steel plate (thickness 2.0mm steel plate) to be welded can bear certain tap water supply pressure, is applicable to forced circulation and Natural Circulation.Installing heat-insulation layer additional outside the utility model boiler 1 can be incubated for a long time.The utility model heat-exchange tube 2 is connected by water inlet pipe and water outlet pipe 5,6 and home-use heating installation.
