Description

A heat pipe type - all glass vacuum tube solar water heater

technical field

The utility model relates to a vacuum tube solar water heater, in particular to a heat pipe type-all glass vacuum tube solar water heater.

Background technique

All glass vacuum heat collectors are divided into four types. Type I is an ordinary all-glass vacuum tube. The glass tube absorbs the sun's heat and transfers it directly to water. The heat transfer resistance is very small, but there is water in the vacuum tube, which brings disadvantages: easy to freeze, scale, and 30% of the water in the tube Not easy to take out.

In order to solve the above-mentioned shortcomings, other types of vacuum heat collecting tubes have been developed. The heat pipe technology used in the aerospace field in the 1950s was gradually introduced into the solar energy field in the 1980s. The purpose is to improve the thermal efficiency of the vacuum tube solar water heater and the safety and antifreeze performance of the product. Successively developed Type II: heat pipe-metal heat-sealed solar vacuum heat collection tube, which is a vacuum tube that uses heat-seal technology to seal the fins with selective coating and the metal heat pipe. Type III: heat pipe type-all glass vacuum tube, that is, metal fins and metal heat pipes are placed in an all glass vacuum tube with a selectively coated inner tube wall. Type IV all-glass heat pipe vacuum tube, that is, the glass inner tube is made into a heat pipe, replacing the metal heat pipe in Type II or Type III. Applying these technologies to solar water heaters, many new solar heat utilization products have been developed, and their respective advantages and disadvantages are as follows:

Type II heat pipe-metal heat-sealed vacuum collector tube water heater, with selectively coated fins inside the glass tube, the absorbed solar heat is transferred to the heat-conducting sleeve in the water tank through the superconducting metal heat pipe to heat the water in the water tank, and the vacuum collector The price of water heaters assembled with heat pipes is as high as 5,000-6,000 yuan per unit, and the maintenance cost is high: the thermal efficiency is greatly reduced after the condensation end is scaled, and a broken pipe needs about 400 yuan to replace.

Type III heat pipe type-all glass vacuum tube water heater, sunlight directly irradiates the inner tube wall of the vacuum tube with selective coating, the inner tube gradually heats up to heat the metal fins, and transfers heat energy to the water in the water tank through the heat pipe. At this stage, copper water heat pipes are 25-28 yuan/piece, and the price is relatively low. But the heat pipe is connected with the rubber ring of the water tank, and the heat pipe cannot be pulled out after fouling, and it is not easy to replace.

The IV-type all-glass heat pipe vacuum tube water heater has high-efficiency heat absorption, superconducting heat transfer, and low cost. However, the glass heat pipe is easily damaged and has a short service life, and the current technology is not yet mature.

In summary, how to improve the Type III vacuum tube water heater, overcome its complex structure and difficult maintenance defects, improve its antifreeze safety, and reduce costs has great practical significance and market benefits.

Utility model content

Further, the vacuum tube is an all-glass vacuum tube with a diameter of 102 mm and a length of 1800 mm.

Because the utility model increases the diameter of the vacuum tube and reduces the number of metal heat pipes used, the structure of the utility model water heater is simpler and the cost is reduced.

Further, a solenoid valve (empty valve) is installed on the upper part of the cold and hot water pipe.

There is no water in the vacuum heat collecting tube of the water heater of the utility model, and a solenoid valve is installed on the cold and hot water pipe of the water tank. When in use, the solenoid valve is energized for bathing and watering. Higher performance and more stable operation.
