Abstract

The utility model relates to anti-freezing solar heat accumulation devices, in particular to an anti-freezing solar heat accumulation device. More specifically, a water tank is arranged at the lower ends of solar heat accumulation tubes; when the external temperature reaches a freezing degree, all working fluid in the water tank and exposed pipelines will flow back into a thermal accumulation set so as to prevent the anti-freezing solar heat accumulation device from being frozen. According to the anti-freezing solar heat accumulation device, through the arrangement of a temperature sensor, when the temperature of the starting fluid is below a set temperature, a circulation pump will stop operating, and all the starting fluid will return to the thermal accumulation set, so that burst or damage caused by freezing is prevented, the damaged degree of the device is low, and the maintenance cost is low.

Detailed description of the invention

As shown in Figure 1, the utility model provides anti-freeze solar Accumulated Heat Units, the inner thermal-arrest group 10 of inserting sink pipe 11 that forms, lower end one side of thermal-arrest group 10 forms the circulating pump 20 being connected with supply pipe 22, form the tank 30 being connected with supply pipe 22, the top of tank has been connected to form multiple solar energy heat collection pipes.

The return pipe that forms startup valve on the pipeline of supply pipe 22 forms and is connected with heat build-up groove, the return pipe 25 forming in the inside of tank 30 forms and is connected with heat build-up groove, in the inside of tank 30, form antifreeze temperature sensor 35, form starter gate valve 26 and rely on antifreeze temperature sensor to carry out running.

The sink pipe 11 of thermal-arrest group 10 upper ends forms the heat exchange that relies on solar energy and accept the working fluid of heat energy.

Lower end one side of thermal-arrest group 10 has supply pipe 22 to connect, and supply pipe 22 is connected to the lower end of tank 30, forms circulating pump 20 on the pipeline of supply pipe 22.

Be formed at the check-valves 24 that circulating pump 20 is kept apart, check-valves 24 forms working fluid can adverse current not arrive circulating pump.

Return pipe 25 is connected to form because of supply pipe 22 and thermal-arrest group 10, is connected to the upper end of the check-valves 24 of supply pipe 22.

On the pipeline of return pipe 25, form starter gate valve 26, starter gate valve 26 is connected to form antifreeze temperature sensor 35 automaticitys with antifreeze temperature sensor 35 and starts.

The end of the upper end of thermal-arrest group 10 has formed the outside return pipe 12 of air outlet 14.

Tank 30 forms body, the inner return pipe 32 that forms, and the upper end of body 31 forms and is connected with the lower end of most solar energy heat collection pipe 40.

All seal up the upper end of solar energy heat collection pipe 40, and lower end is that open outer glass pipe 41 is made up of the internal circulation pipe being communicated with return pipe 32 with upper end open lower.

Outer glass pipe 41 is to be fixed by fixed head, and lower end end is to be communicated with the outside of tank body, and internal circulation pipe 42 is that lower end end is connected with each return pipe 32 of tank.

The return pipe 32 of tank 30 with and the outside return pipe 12 that is connected of thermal-arrest group 10 form and connect.

Antifreeze temperature sensor 35 is formed on the outside of tank 30, and antifreeze temperature sensor 35 is the operations that determine operation cycle pump 20 and starter gate valve 26 according to temperature.

Tank 30 or solar energy heat collection pipe 40 always all equally form most temperature sensors and are formed on according to temperature sensor operation cycle pump 20 general operation that thermal-arrest group 10 stores.

Form timer control starter gate valve 26 and circulating pump 20 in thermal-arrest group 10, the words starter gate valve 26 of timer shut-down operation is just opened circulating pump 20 and is quit work the whole backwater of fluid to thermal-arrest group 10, and the words starter gate valve 26 of timer initiation operation can be according to temperature sensor or 35 shut-down operations of antifreeze temperature sensor with circulating pump 20.

The best embodiment that the anti-freeze solar Accumulated Heat Units of this utility model starts is described as follows.

The words of the temperature rise of solar energy heat collection pipe 40 are because of temperature sensor, circulating pump 20, start fluid can circulate thermal-arrest group 10 can store heat.

At this moment,, because starter gate valve 26 is closing, on return pipe 25, can not allow and start fluid formation.

The bottom of the thermal-arrest group 10 of startup fluid is at the inside of tank 30 streamer, and the inside of outer glass pipe 41 simultaneously, starts fluid and also can gradually fill.

Then, starting fluid can heat, and induces pipe to move to outside return pipe 12 by inside, then flows out toward heat accumulation group by outside return pipe 12.

At this moment, all discharge pure startup fluid rotary heating by air outlet 14 at the air of solar energy heat collection pipe 40 inside.

The water that the inside of the sink pipe 11 that insert the inside of thermal-arrest group 10 comprises, by heat exchange, is hot when use.

According to above-mentioned solar energy heat collector, in the time starting in way that antifreeze temperature sensor 35 detects below the temperature value of setting, circulating pump 20 can stop, and starter gate valve 26 can be opened, at the startup fluid of tank 30 and each solar energy heat collection pipe 40 all from thermal-arrest group 10 backwater.

With above-mentioned, start fluid from the whole backwater of thermal-arrest group 10, the inside of tank 30 and solar energy heat collection pipe 40 is all empty state, thus no matter temperature can how to decline can not freeze quick-fried.

While starting fluid all from the inside backwater of thermal-arrest group 10, because of than the more tank 30 of lower end of solar energy heat collection pipe 40 positions, starting fluid can more perfect backwater.This part has distincter difference than other solar energy heat collectors.

On solar energy heat collector, form timer, can only be arranged on the period that the sun rises, the state that timer stops, circulating pump 20 can stop starter gate valve 26 can be opened, and starts fluid all from thermal-arrest group 10 backwater by return pipe 25.

The utility model antifreeze solar energy heat collector, because of temperature sensor, starts the temperature of fluid below the temperature arranging, circulating pump can decommission, because starting fluid whole backwater to heat accumulation group, prevent from freezing quick-fried freezing/freeze brokenly, device is damaged little, the few texts of maintenance expense.

The utility model is technology-centred, has diversified possibility within the scope of utility model.
