Description

The combined type heat pipe solar energy water heater

The utility model belongs to solar water heater, especially a kind of combined type heat pipe solar energy water heater.

In recent years, solar water heater has obtained using widely.Because hot pipe technique has that heat transfer rate is fast, efficient is high, unidirectional heat transfer and low temperature adaptability, so heat pipe solar energy water heater has had development faster.Normally heat pipe evaporator section is made heat pipe collector, heat pipe condenser section is made heat exchange of heat pipe, and both is communicated with as a whole, and this heat pipe solar energy water heater volume is bigger, gives and makes, transportation, installs and make troubles.

The purpose of this utility model provides a kind of rational in infrastructure, dependable performance, be convenient to the combined type heat pipe solar energy water heater making, transport and install.

In technical solutions of the utility model, the heat pipe collector that has fairlead places in the lighting heat preserving casing, constitute heat pipe solar thermal collector, heat exchange of heat pipe places in the attemperater, constitute the heat pipe thermal storage device, it is characterized in that: the two ends of heat exchange of heat pipe are passed the attemperater tank wall respectively and are stretched out outside the attemperater, and the fairlead of one end and heat pipe collector adopts removable being tightly connected, and the other end is equipped with the topping up air bleeding valve.

Heat pipe collector can adopt removable being tightly connected such as pipe collar is connected, flange connection, pipe joint connection with heat exchange of heat pipe in the technical program.

Adopt technique scheme, heat pipe solar thermal collector and heat pipe thermal storage device help making, transport and install for dividing body structure; Both adopt removable being tightly connected, easy accessibility, and sealing is reliable; The topping up air bleeding valve is used for the erecting bed and fills heat-conducting work medium and adopt sunlight thermal exhaust legal system to get vacuum, and is easy to operate.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is the utility model structural representation.

Fig. 2 is a pipe collar syndeton enlarged drawing in A position among Fig. 1.

Fig. 3 is an A position flange connection enlarged drawing among Fig. 1.

Fig. 4 is a pipe joint syndeton enlarged drawing in A position among Fig. 1.

Fig. 5 is the structural representation of heat exchange of heat pipe another storing form in attemperater in the utility model.

Shown in Figure 1, heat pipe collector 2 is to be formed by two sheet metal punching presses, assembly weldings, leave several vertical passages 11 between two plates, by upper and lower two interface channels 10 and 12, and be connected together with fairlead 3, heat pipe collector 2 is contained in the lighting heat preserving casing 1, has constituted heat pipe solar thermal collector.The heat pipe thermal storage device comprises heat exchange of heat pipe 5 and attemperater 4, radiating fin 7 is housed on the heat exchange of heat pipe 5, to increase heat exchange area, its two ends are passed the tank wall of attemperater 4 respectively and are stretched out outside the attemperater, topping up air bleeding valve 6 is equipped with in its upper end, the fairlead 3 of lower end and heat pipe collector 2 adopts removable being tightly connected, thereby makes heat pipe collector 2 and heat exchange of heat pipe 5 connect into a complete hot-pipe system, also is provided with entery and delivery port 9 and exhaust 8 on the attemperater 4.

Removable being tightly connected shown in Figure 2 is that pipe collar connects, adopt two ends to be processed with left-hand thread or right-hand thread respectively, there is the pipe collar 13 that sealing ring 14 is housed on ring-type intervallum, the ring-type intervallum centre, be processed with corresponding left-hand thread or right-hand thread respectively on connected two tube heads, when screwing pipe collar 13, connected two mouth of pipe end faces compress sealing ring 14, realize being tightly connected.

Removable being tightly connected shown in Figure 3 is that flange connects, and connected two nose end portions are welded with respectively between flange 16 and 17, two flanges gasket seal 19, by fastening bolt 15 and nut 18, flange 16, gasket seal 19 and flange 17 is linked together.

Removable being tightly connected shown in Figure 4 is that pipe joint connects, connected two nose end portions are welded with

joint

20 and 23 respectively, be with coupling nut 21 on the joint 20, be processed with screw thread on the joint 23, sealing ring 22 is housed in the cannelure on its end face, by coupling nut 21 joint 20 is tightly connected with joint 23 and is in the same place.

Shown in Figure 5 is another storing form of heat exchange of heat pipe.Heat exchange of heat pipe 5 places in the attemperater 4, be the U-shaped tubular construction, its two ends are passed the tank wall of attemperater 4 and are stretched out its side, two ends keep the suitable gradient from low to height, the end that topping up air bleeding valve 6 is housed is higher than the other end, on the pipeline section of heat exchange of heat pipe 5 in attemperater 4 radiating fin 7 is housed.

The utility model is operation like this and work: fill an amount of low boiling heat-conducting work medium (as methyl alcohol in heat pipe solar energy water heater by topping up air bleeding valve 6, acetone), heat-conducting work medium comes together in the bottom of heat pipe collector 2, in sunny and attemperater 4, do not have under the condition of water, place the heat pipe collector 2 in the lighting heat preserving casing 1 to absorb sunlight, temperature raises rapidly, when temperature reaches 50-80 ℃, the heat-conducting work medium boiling, the hot-pipe system internal pressure raises, at this moment by opening and closing topping up air bleeding valve 6, discharge intrasystem air and a small amount of heat-conducting work medium steam, can obtain the needed vacuum of heat pipe solar energy water heater operate as normal.When normal the use, in attemperater 4, add water, heat pipe collector 2 is passed to heat exchange of heat pipe 5 with the evaporation of heat energy by heat-conducting work medium endlessly, thereby the temperature of water is constantly raise, in 5 pairs of water heating of heat exchange of heat pipe, the heat-conducting work medium condensation is also returned the bottom of heat pipe collector 2, forms the circulation of heat-conducting work medium.The unidirectional heat transfer of this solar water heater, high insulating effect; Good heat-transfer, quick heating; Low temperature resistant freeze proof, dependable performance.When the lowest temperature-10 ℃, water temperature reaches 40 ℃, but the four seasons use.

In the technical program, the storing of heat exchange of heat pipes 5 in the attemperater 4, be not limited to two ends shown in Figure 1 respectively upper and lower to, also can be as shown in Figure 5, its two ends (or wherein an end) are located at the side of attemperater 4, but the end that topping up air bleeding valve 6 is housed should be higher than the other end.In addition, lower when heat pipe collector 2 temperature rises, in the time of can not using thermal exhaust legal system vacuum or vacuum not enough, when perhaps not adopting the thermal exhaust method, topping up air bleeding valve 6 can be replaced by the tubule that the topping up of finding time is used, find time the mouth of pipe to be pressed from both sides behind the topping up flat with vaccum-pumping equipment, and seal with gas welding.
