Description

Can change the underneath type multi-cavity solar water container of heat pipe

Technical field

The utility model relates to a kind of apparatus for heating water by solar energy, especially a kind of underneath type multi-cavity solar water container that changes heat pipe.

Background technology

The non-press-bearing water tank of flat plate solar water heater is overhead and installs at present, promptly is installed in the heat collector top.This is to rely on hot water density littler and rise to the water tank heating than cold water.And bearing type water tank, heat-conducting medium need lean on water circulating pump through very long spiral heat pipe to the heating that circulates of the water in the water tank, water tank is generally vertical installation.Heat pipe and can not changeing, temperature is controlled to be electronic type.

Many solar water heaters in use for some time, heat pipe or thermal-collecting tube and water engaging surface can produce incrustation scale, have a strong impact on the heat transfer efficiency of heat pipe.This also is that many solar water heaters have been used the reason that thermal effect a period of time of after is bad even scrap.

The utility model content

The purpose of the utility model provides a kind of underneath type multi-cavity solar water container that changes heat pipe.Heat pipe can take out cleaning, makes water heater often keep higher heat transfer efficiency, has prolonged the service life of solar water heater greatly; Do not need water circulating pump and electron temperature-control, be fit to no electrical environment and use, practice thrift cost, water tank is a multi-cavity structure, effectively improves the utilization rate of hot water, saves water and energy.

The utility model posed to the technical program are:

Water tank 11 is the pressure-bearing type, adopts underneath type to be installed on the fixed mount 16 of flat plate collector 2 back, and an expansion drum 1 is installed in outlet 8 on heat collector 2 tops, establishes thermal insulation board 15 in the water tank 11 and forms multi-cavity structure; Disconnectable heat pipe 4 is fixed in water tank and sealing through internal thread interface 13, external screw thread straight coupling 12 and the sealing ring 14 at water tank 11 two ends, and check-valves 5 is installed in heat pipe 4 exits.

The major advantage of the utility model:

(1) heat pipe can take out and clean or change, and makes water heater often keep higher heat transfer efficiency, has prolonged the service life of solar water heater greatly.

(2) do not need water circulating pump and electron temperature-control, be fit to no electrical environment and use, this measure can save energy and practice thrift cost.

(3) the metal heat-conducting pipe is very short, greatly reduces manufacturing cost.

(4) water tank is a multi-cavity structure, effectively improves the utilization rate of hot water, saves water and energy.

(5) water tank is installed on the fixed mount of flat plate collector back, utilizes blocking of heat collector, and the protection water tank avoids exposing to the sun and rain.And can practice thrift the installation water tank location, and be particularly suitable for balcony and skin and install, help architecture-integral.

(6) to the central heating water system, can be according to the size of water consumption, series connection or connection in series-parallel water tank below the matrix heat collector.Make hot water push up one case equal eshaustibility of every case hot water for one the case, improved the utilization rate of hot water greatly.Not resembling the large water tank hot and cold water mixes mutually and reduces water temperature.The underneath type water tank install and not occupied ground with solve the building structure problem that causes because of large water tank is overweight.

The specific embodiment

This solar water container 11 is the pressure-bearing type, adopts underneath type to install, and promptly is installed on the fixed mount 16 of flat plate collector 2 back; Like Fig. 1, water tank 11 is lower than heat collector 2 tops outlet 8, and long together with thermal-arrest plate 2; And horizontal positioned, water tank 11 shapes can be circle or triangle.The water of water tank 11 is through the thermal medium in the through-type heat pipe 4 in water tank 11 centers water to be heated.About 2 meters of heat pipe 4 length, long together with water tank 11, be heat conduction good metal material.Through internal thread interface 13 and the external screw thread straight coupling 12 and sealing ring 14 that is fixed on water tank 11 two ends, heat pipe 4 is fixed, and sealed with water tank 11.Heat pipe 4 two ends are connected through exporting up and down with heat collector 2 with communicating pipe 9 communicating pipe 6.Use a period of time can the external screw thread straight coupling 12 of heat pipe 4 be opened, take out heat pipe 4 and clean incrustation scale or replacing.

In the flat plate collector 2 is 300# conduction oil medium, does not leak water, and can not produce incrustation scale.The conduction oil medium is the variation through temperature difference, in system, produces siphonic effect and slowly circulation.

Water heater is when operation, and the medium after heat collector 2 will heat through communicating pipe 9, conducts the water in the feed-tank 11 with heat by heat collector outlet 8 through heat pipe 4 time, return heat collector 2 by communicating pipe 6 through heat collector import 7 again.Form closed circuit.Because heat pipe 4 is through-type, resistance is very little during medium circulation, is not needing under the water circulating pump effect, and medium can circulate voluntarily, endlessly the water of 11 li of heating water tank.

The back volumetric expansion because the conduction oil medium is heated needs expansion drum 1 of outlet 8 installations on heat collector 2 tops, like Fig. 2, to absorb expansion energy.But and, heat collector 2 is moved under passive state through the air in the steam vent emptying heat collector 2 of expansion drum 1.

Water tank 11 is a multi-cavity structure, is generally two chambeies or three chambeies, like Fig. 2, can make the water temperature in the water tank 11 be divided into high, medium and low three districts.Cut off with thermal insulation board 15 between every alveolus, above thermal insulation board 15, reserve the mouth of a river, with other chamber intercommunications, heat pipe 4 perforation are stayed in the centre.During water tank 11 heating, heat pipe 4 heats the high-temperature region at first, and then in, low-temperature space, make water tank 11 at short notice, the water temperature of high-temperature region can satisfy instructions for use.Be particularly suitable for the short situation of light application time.When water, cold water is introduced into the low-temperature space chamber, again to middle temperature chamber, after rate of thermal water utilization to the user, can fully be improved in the high temperature chamber.In addition, the auxiliary electrical heating tube only is located at the high temperature chamber, can shorten the assistant heating time and energy-conservation.

In order to prevent water tank 11 water overtemperatures, in heat pipe 4 exits constant temperature check-valves 5 has been installed, when reaching design temperature, constant temperature check-valves 5 cuts out, and the circulation heating stops.The water of water tank 11 can overtemperature.
