Abstract

The utility model relates to a solar heat-collecting underground storage and exchange device, which is characterized in that: the solar heat-collecting underground storage and exchange device consists of a solar heat collector and a heating apparatus, wherein, an underground part is a heat storage sandpit; the heat storage medium is silver sand; a heat transfer guide pipe enters into the heat storage sandpit through the solar heat collector, is connected to a multilayered disc suspension pipe which is flatly arranged inside the heat storage sandpit, returns to the solar heat collector to form a loop; a heat-collecting recycle pump is arranged on a position where the heat transfer guide pipe passes through the inside of a room; a heat exchange guide pipe which is connected with a radiator enters into the heat-collecting sandpit and returns to form an independent loop; and a heat exchange recycle pump is arranged on a position where the heat exchange guide pipe passes through the inside of the room. The solar heat-collecting underground storage and exchange device has the advantages that: the storage and the balanced utilization of solar energy are realized; and heat energy can be stored in fine weather or in summer and heat energy can be utilized in gloomy weather or in winter. Moreover, the solar heat-collecting underground storage and exchange device has the advantages of simple structure, low manufacturing cost, high thermal efficiency, environmental protection, energy conservation, convenience and safety, economy and applicability and so on.

Description

The underground storage switch of solar energy heating

Technical field

The utility model relates to a kind of solar energy and utilizes engineering

Background technology

At present, the solar energy utilization mainly is forms such as solar water heating system, solar electrical energy generation, solar heated green house.These equipment all are that instant type utilizes solar thermal energy, in case weather is turned out cloudy, cloud and mist keeps the sun off, and the solar absorption energy storage device is with regard to cisco unity malfunction, common solid, liquid heat-storing device are also also little because of the less heat energy benefit of material volume, thereby influence people's normal heating life.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of solar energy heating underground storage switch, to solve urban and rural residents' heating residential in winter, the hot water problem of having a bath, can also be used to plant the snow melt safety of culturing industrial or agricultural processing, urban road and airfield runway.

The technical solution of the utility model is achieved in that the underground storage switch of solar energy heating aerial part is made up of solar thermal collector, warmer, its under ground portion is the heat accumulation sand pit, heat-storage medium is a fine sand, defeated heat pipe enters the heat accumulation sand pit by solar thermal collector, be connected the outstanding pipe of several layers of dish that yaw is provided with in the heat accumulation sand pit, return solar thermal collector, constitute the loop, defeated heat pipe through the room in the position thermal-arrest circulating pump is set; The heat exchange conduit that connects radiator enters the thermal-arrest sand pit and returns, and constitutes independent loop, and the heat exchange conduit is provided with the heat exchange circulating pump through position in the room.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified;

Fig. 1 is the utility model structural representation;

1 solar thermal collector, 2 thermal-arrest circulating pumps, 3 defeated heat pipes, 4 heat accumulation sand pits, 5 spiral tubes, 6 heat exchange conduits, 7 heat exchange circulating pumps, 8 heat exchangers, 9 rooms among the figure.

Adopting good effect of the present utility model is storage and balanced utilization of having realized solar energy; Can fine or Summer heat energy storage, cloudy day or winter are utilized heat energy, have simple in structure, cost of manufacture is low, thermal efficiency height, Environmental protection and energy saving, the advantage such as convenient and safe, economic and practical. Northern area dwelling house in winter, school and car have been solved Between the difficult problem of warming oneself, can also in industrial and agricultural production, traffic safety, play a role. Be applicable to agricultural, road, city The field such as road, airport.

The specific embodiment

As shown in the figure; The solar thermal collector (1) that is arranged on the building top adopts the solar vacuum glass tube heat collector, defeated heat pipe (3) adopts seamless steel pipe to make, defeated heat pipe (3) through room (8) in the position thermal-arrest circulating pump (2) is set, connect the several layers of spiral tube (5) in the heat accumulation sand pit (4), heat accumulation sand pit (4) is long 6 meters, wide 4 meters, dark 2 meters pond, underground hole, lay several layers of yaw spiral tube of placing (5) and defeated heat pipe (3) the formation loop that is connected solar thermal collector (1) in the pond, hole, bury with meticulous sandy soil and to tamp, pond, hole wall is equipped with heat-barrier material, husky pond top layer flattens with heat-insulating materials such as " perlites " and waterproof dirt, the top is paved courtyard with plate brick or cement mortar whole, filling conductive fluid in solar thermal collector (1) and the defeated heat pipe (3); The heat exchange conduit (6) that connects heat exchanger (8) enters thermal-arrest sand pit (4) and returns around a circle, constitutes independent loop, and heat exchange conduit (6) is provided with heat exchange circulating pump (7) through interior position, room (9).

Claims
