Abstract
The utility model relates to a heat absorbing pipe of a solar water heater, which belongs to the technical field of a flat-plate solar collector. The heat absorbing pipe comprises a pipe body. The inside diameter of the middle part of the pipe body is smaller than the inside diameters of the two ends of the pipe body. The utility model adopts the orderly freezing principle. During working, the two ends of the heat absorbing pipe are respectively communicated with an upper heat-collecting pipe and a lower heat-collecting pipe. When the solar water heating system is in the working condition, the heat absorbing pipe is filled with water. When the temperature of the operating environment is below 0 DEG C, the water circulation stops, and the water in the heat absorbing pipe begins freezing. Since the inside diameter of the middle part of the heat absorbing pipe is smaller than the inside diameters of the two ends thereof, the radiating speed of the middle part is higher than the radiating speed of the two ends, and water in the middle part freezes prior to the freezing of water in the two ends. The excessive water is discharged and squeezed into the upper circulating pipe and the lower circulating pipe after freezing. With the orderly freezing principle, the utility model ensures that the heat absorbing pipe can not be damaged during freezing, thereby prolonging the service life of the heat absorbing pipe.
Description
Technical field
The utility model relates to a kind of technical field of flat type solar heat collector, relates in particular to the structure of endothermic tube.
Background technology
Flat type solar heat collector, comprise heat-insulation layer and the thermal-arrest plate that in heat-insulation layer, is provided with, the thermal-arrest plate comprises heat absorbing sheet, goes up thermal-collecting tube, following thermal-collecting tube and some endothermic tubes, the two ends up and down of each endothermic tube are communicated with thermal-collecting tube and following thermal-collecting tube respectively, the straight tube that existing endothermic tube equates for the upper, middle and lower internal diameter, under the situation below 0 ℃, the water freezing in the endothermic tube expands in no sunlight and environment temperature, thereby with endothermic tube and upper and lower thermal-collecting tube bursting by freezing.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of endothermic tube that is difficult for bursting by freezing, long service life to be provided.
The purpose of this utility model is achieved in that a kind of endothermic tube of solar water heater, comprises body, and the middle internal diameter of described body is less than the two ends internal diameter.
The utility model has utilized and has freezed principle in order, and during work, the endothermic tube two ends are communicated with thermal-collecting tube and following thermal-collecting tube respectively.Solar water heating system is full of water in working order the time in the endothermic tube.When running environment below 0 ℃ the time, the water circulation stops, the water in the endothermic tube begins to freeze because the middle internal diameter minimum of endothermic tube, it is the fastest to dispel the heat, so at first freeze, the two ends internal diameter is big, after freeze.Water is discharged the water that has more after freezing and is clamp-oned in upper circular tube and the following circulation pipe, the principle of freezing in order, thus guarantee endothermic tube to freeze and not bad, thus the service life of endothermic tube prolonged.
Produce for convenience, described body comprises the straight tube of at least three different inner diameters, and the straight tube that internal diameter is bigger is connected the outer end of the less straight tube of internal diameter.
In like manner, described body comprises two conical pipes, and the small end of described two conical pipes interconnects.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be the endothermic tube of first kind of solar water heater, comprise little internal diameter straight tube 1, internal diameter straight tube 2 during the two ends of little internal diameter straight tube 1 connect respectively, the outer end of every middle internal diameter straight tube 2 connects large diameter straight tube 3.
As shown in Figure 2, be the endothermic tube of second kind of solar water heater, comprise that the small end of 4, two conical pipes 4 of two conical pipes interconnects.
Claims (3)
1. the endothermic tube of a solar water heater, it is characterized in that: comprise body, the middle internal diameter of described body is less than the two ends internal diameter.
2. the endothermic tube of solar water heater according to claim 1, it is characterized in that: described body comprises the straight tube of at least three different inner diameters, the straight tube that internal diameter is bigger is connected the outer end of the less straight tube of internal diameter.
3. the endothermic tube of solar water heater according to claim 1, it is characterized in that: described body comprises two conical pipes, and the small end of described two conical pipes interconnects.
