Abstract

The utility model discloses a flat plate solar heat collector with defrosters. The flat plate solar heat collector with the defrosters comprises a heat collector shell, a plurality of collecting pipes, a plurality of row pipes, a heat storage box and defrosters, wherein the plurality of collecting pipes are installed in the heat collector shell; the plurality of row pipes are installed in the heat collector shell and are connected with the collecting pipes; the heat storage box is connected with the collecting pipes; the defrosters are installed in one end of at least one collecting pipe; each defroster comprises a blind pipe and a temperature sensing blind pipe, wherein the blind pipe is installed in one end of each collecting pipe; a heating device is installed in the blind pipe; the temperature sensing blind pipe is installed in one end of each collecting pipe; the temperature sensing blind pipe is internally provided with a temperature control switch; and when the medium temperature in the collecting pipes is lower than the set value, the temperature control switch is switched on, media in the collecting pipes are heated by the heating device. Media in a flow channel of the flat plate solar heat collector can be effectively prevented from frosting, and the flat plate solar heat collector with defrosters is especially suitable for being used under a low-temperature environment.

Description

Flat-plate solar collector with defroster

Technical field

The utility model relates to the flat-plate solar collector technical field, more particularly, relates to a kind of flat-plate solar collector with defroster.

Background technology

Flat-plate solar collector has passed through the development of decades, and it is ripe and perfect that technology has more become, and possessed the not available advantageous feature of other type solar thermal collector, for example is particularly suitable for will trying to achieve etc. with architecture-integral.Make a general survey of world solar markets; All the time be to take product as the leading factor with flat plate solar water heater in fact, the solar water heating system more than 90% all adopts flat-plate solar collector, and solar thermal collector is to carry out the significant energy conversion equipment that solar energy utilizes; Mainly comprise two kinds of vacuum tube solar heating element and flat type solar heat collectors; And flat type solar heat collector possesses advantages such as long service life, corrosion-resistant, fault are few, has progressively become the main flow of solar thermal collector, but under low temperature environment; Medium in the runner of flat type solar heat collector freezes easily, causes the flat type solar heat collector can't operate as normal.

The utility model content

The purpose of the utility model is to overcome above-mentioned defective of the prior art, provides a kind of interior medium of runner of flat type solar heat collector that can effectively prevent to freeze, and is particularly useful for the flat-plate solar collector with defroster that uses under the low temperature environment.

For realizing above-mentioned purpose, the technical scheme that the utility model provides is following: a kind of flat-plate solar collector with defroster is provided, comprises the heat collector housing; Be installed in some collectors in the heat collector housing; Be installed in some combs that are connected with collector in the heat collector housing, the heat storage box that is connected with said collector is equiped with defroster in an end of at least one collector; This defroster comprises the blind pipe that is installed in collector one end; Be equiped with heater in the blind pipe, also comprise the temperature-sensitive blind pipe that is installed in collector one end, be equiped with temperature detect switch (TDS) in this temperature-sensitive blind pipe; When the medium temperature in the collector was lower than setting value, the temperature detect switch (TDS) conducting made heater heat the medium in the runner of collector and comb formation.

The described flat-plate solar collector beneficial effect with defroster of the utility model is: through in an end of at least one collector, being equiped with defroster; This defroster comprises the blind pipe that is installed in collector one end; Be equiped with heater in the blind pipe; Also comprise the temperature-sensitive blind pipe that is installed in collector one end; Be equiped with temperature detect switch (TDS) in this temperature-sensitive blind pipe, when the medium temperature in the collector was lower than setting value, the temperature detect switch (TDS) conducting made heater heat the medium in the runner of collector and comb formation.The interior medium of runner that can effectively prevent flat type solar heat collector freezes, and is particularly useful for using under the low temperature environment.

Below in conjunction with accompanying drawing and embodiment the described a kind of flat-plate solar collector with defroster of the utility model is described further.

Description of drawings

Fig. 1 is the described structural representation with flat-plate solar collector of defroster of the utility model;

Fig. 2 is the I place enlarged drawing of Fig. 1.

The specific embodiment

Below be the said a kind of flat-plate solar collector preferred example of the utility model, therefore do not limit the protection domain of the utility model with defroster.

With reference to Fig. 1, Fig. 2, a kind of flat-plate solar collector with defroster is provided, comprise heat collector housing 1; Be installed in the some collectors 2 on the heat collector housing 1; Be installed in the some combs 10 that are connected with collector 2 in the heat collector housing 1, the heat storage box 3 that is connected with said collector 2 is equiped with defroster 4 in an end of at least one collector 2; This defroster 4 comprises the blind pipe 5 that is installed in collector 2 one ends; Be equiped with heater 6 in the blind pipe 5, also comprise the temperature-sensitive blind pipe 7 that is installed in collector 2 one ends, be equiped with temperature detect switch (TDS) 8 in this temperature-sensitive blind pipe 7; When the medium temperature in the collector 2 was lower than setting value, the interior medium of runner that temperature detect switch (TDS) 8 conductings constitute 6 pairs of collectors of heater 2 and comb 10 heated.Heat carries out the heat conduction through collector 2 and the comb 10 that is installed in the heat collector housing 1, and the medium temperature in the runner is raise, and prevents that the medium in the runner from freezing, thereby improves the heat exchange efficiency of flat-plate solar collector.

Said heater 6 is light wave heating tube or microwave applicator.

One end of said collector 2 also is equiped with protective cover 9, prevents that heater 6 is by damage.

The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
