Description

The new type high temperature solar water heater

Technical field:

The utility model relates to a kind of solar thermal collector, particularly utilizes the high-temperature solar water heater of vacuum heat collection pipe thermal-arrest.

Background technology:

At present, domestic Solar Heater Market is become increasingly prosperous, and it is widely acknowledged energy-conserving and environment-protective that the solar water appliance has, convenient and safe, advantage such as operating cost is low, becomes the first-selection of family's Bathing apparatus.On prior solar water heater is general storage tank is arranged, storage tank connects many thermal-collecting tubes and is the top-heavy roof that is fixed on, the problem of its common existence is: the thermal-collecting tube heat absorption capacity has much room for improvement, storage water tank heat insulation is low, water is subject to contaminating impurity in the case, wholesomeness is poor, and the water route structure is undesirable, top-heavy uneasy congruence during installation.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of new type high temperature solar water heater, and this water heater heat absorption capacity is strong, and water storage clean hygiene, good heat preservation performance, structure are more reasonable.

For achieving the above object, the utility model adopts following technical scheme:

This new type high temperature solar water heater comprises water inlet pipe, and magnetic valve is housed on the water inlet pipe, and water inlet pipe connects thermal-collecting tube, and the thermal-collecting tube skin is a glass tube with vacuum, and internal layer is a metal tube, and is gapped between the two, irritates with oil; A plurality of thermal-collecting tubes are connected by water pipe, and terminal thermal-collecting tube is provided with temperature probe; Hot-water line connects storage tank and downcomer; Be provided with a plurality of water storage glass liners in the storage tank, hot-water line is divided into a plurality of arms and connects each water storage glass liner in storage tank; The water storage glass liner is provided with blast pipe, wherein is provided with water-level probe in the water storage glass liner.

This new type high temperature solar water heater, the thermal-arrest plate of being made up of many thermal-collecting tubes places the top of storage tank.

This new type high temperature solar water heater is equipped with a reflective mirror behind each root thermal-collecting tube.

This new type high temperature solar water heater, dust cap is equipped with on the thermal-collecting tube top.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

1, thermal-collecting tube has adopted tubular construction in the liquid heat medium conducting tube, fully absorbs solar heat, cooperates reflective mirror, fast thermal-collecting tube is heated to 3-4 times of sun direct projection temperature, and temperature of cold water rises is fast, the temperature height.As the outer layer glass tube fragmentation, water can not leak, and does not influence use.

2, storage tank adopts integrated water storage glass liner structure, high insulating effect, and clean hygiene can be made as the high temperature drinking water; Adopt the inner flask of maturation process production in enormous quantities to compare with existing stainless steel integrated foaming storage tank, cost is more cheap.

3, hot and cold water turnover replacing process in unique pipe, each pipe serial connection, the terminal temperature probe of installing have been adopted, behind the set water temperature, magnetic valve is opened as required, and hot water in the thermal-collecting tube is replaced into storage tank, when cold water arrived point for measuring temperature, magnetic valve closed, and second batch of cold water begins heating.Heating, storage separate, and the thermal water utilization time is fast, and water temperature is constant.

4, since storage tank down, the thermal-arrest plate is last, it is top-heavy to have solved existing solar water heater, problem such as lays and leak dangerous.
