Description

A kind of solar water heater water tank

One, technical field

The utility model relates to solar energy utilization technique, and the heat exchanger that refers in particular to water tank inside adopts the solar water heater water tank of a plurality of bend pipe heat exchange.

Two, background technology

At solar energy heat utilization field, there is comprising the multiple matured product of vacuum tube water heater and flat water heater in solar water heater, and plate type solar water heater, with its longer service life and easy installation method, is opened up markets rapidly.Flat plate solar water heater is used the mode of indirect more, and heat-conducting medium is thickness relatively, causes heat transfer efficiency not high.

Current existing a plurality of patents about solar water heater water tank, but can use the heat-conducting medium that boiling point is lower, and install the mobile water tank of jet pipe accelerating medium additional and not yet find.Below list several existing Patents:

Patent " novel solar water heater water tank " (application number: 99229690.0) propose a kind of solar water heater water tank, its inner water tank is divided into two parts that do not communicate by water-stop sheet, and conducts heat by water-stop sheet.

Patent " novel solar water heater water tank " (application number: 200720037641.X) propose a kind of solar water heater water tank, this device is provided with an inner bag in water tank, pure water is housed as heat transfer medium in inner bag, the drinking water of heating water tank outside.

In order to improve flat plate solar water heater heat exchange efficiency, the utility model proposes a kind of solar water heater water tank, be characterized in utilizing the heat-conducting medium of boiling point between 30 to 50 degrees Celsius, and employing has the heat exchanger of a plurality of bend pipes, increase unit mass heat-conducting medium heat output and flowing velocity, improve heat exchange efficiency.

Three, summary of the invention

The utility model proposes a kind of solar water heater water tank, its structure consists of feed tube, shunting chamber, heat exchange bend pipe, the chamber of confluxing, return duct, mounting flange, insulation shell, inner bag, auxiliary electrical heat pipe, outlet pipe, water inlet pipe, thermometric blind pipe.Heat exchanger consists of feed tube, shunting chamber, heat exchange bend pipe, the chamber of confluxing, return duct, and be fixed as one by mounting flange and inner bag, shunting chamber is positioned at the top in the chamber of confluxing, heat exchange bend pipe takes the shape of the letter U and puts upside down, one end is communicated with shunting chamber, and the other end is communicated with the chamber of confluxing through shunting chamber, the densely covered some heat exchange bend pipes of annular on whole heat exchanger, feed tube is communicated with shunting chamber through the chamber of confluxing, and return duct is communicated with the chamber of confluxing.Cold water enters inner bag by water inlet pipe, by outlet pipe, flows out, and outlet pipe oral area approaches inner bag top, and water inlet pipe oral area approaches mounting flange.Auxiliary electrical heat pipe, outlet pipe, water inlet pipe, thermometric blind pipe are all distributed on mounting flange.Insulation shell adopts polyurethane foam material insulation.

The utility model, by having increased the heat exchange area of heat exchanger, improves heat transferring medium flow velocity and improves heat-conducting mode, has improved the heat transfer efficiency between heat collector and water-heater water tank.
