Storage tank 1 outside is formed with certain thickness heat-insulation layer, but the inside is formed with bearing certain pressure, corrosion resistant inner bag 101, the mouth of a river, inner bag 101 bottom 102 and each vacuum heat collection pipe 3 sealing UNICOM, and be provided with water inlet pipe 103 and outlet pipe 104.

Utilize the principle that hot water rises, cold water descends after cold water enters vacuum heat collection pipe 3 heating, the hot water accumulation is prepared against to storage tank 1 and is used.

But above-mentioned solar water heater, storage tank 1 uses with heat collector 2 essential disjunctors, cause solar water heater to install certain space and certain potential energy will be arranged, could be with delivery to using the position, this will influence the user who does not possess certain space and certain potential energy condition solar water heater will be installed.

Summary of the invention

The utility model provides a kind of separated type solar water heater that changes heat collector internal hot-water loop structure for solving the technical problem that exists in the above-mentioned technology.

The utility model is that the technical scheme that the technical problem that exists in the above-mentioned technology of solution is taked is:

A kind of separated type solar water heater of the present utility model, include the outside and be formed with certain thickness heat-insulation layer, but the inside is formed with bearing certain pressure, corrosion resistant inner bag, and be provided with the water inlet pipe that is communicated with heat collector and with the storage tank of the outlet pipe of use position UNICOM; The heat collector that rearranges by vacuum heat collection pipe; The top of heat collector is provided with return duct; Return duct bottom and vacuum heat-collecting seal of tube UNICOM, be provided with in the return duct one be communicated with the water source and and return duct between form the cold water pipe of certain space, the cold water pipe bottom is provided with the cold water down pipe to each vacuum heat collection pipe bottom extension opening in parallel, form the hot water rising passway between cold water down pipe and the vacuum heat-collecting inside pipe wall, return duct top is formed with the water inlet pipe UNICOM of hot water outlet and storage tank; The outside of return duct is surrounded by certain thickness heat-insulation layer; But return duct is made of bearing certain pressure, corrosion resistant metal material; Cold water pipe is made of corrosion-resistant material; The external insulation layer of return duct is made of the polyurethane expanded material.

Advantage and the good effect that the utlity model has are: a kind of separated type solar water heater of the present utility model, owing to adopt said structure, storage tank and heat collector can be separated, by heat collector water is heated, deliver in the storage tank that is higher than heat collector according to the principle that hot water rising cold water descends, realize the long-range purpose of sending water, make the user who does not possess certain space and certain potential energy condition that solar water heater can be installed.

The specific embodiment

For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

The utility model part number is identical with the background technology part number, uses identical part number.

The utility model is to be formed with certain thickness heat-insulation layer by the outside, but the inside is formed with bearing certain pressure, corrosion resistant inner bag 101, and be provided with the water inlet pipe 103 of heat collector 2 UNICOMs and with the storage tank 1 of the outlet pipe 104 that uses position UNICOM; The heat collector 2 that rearranges by vacuum heat collection pipe 3; The top of heat collector 2 is provided with return duct 4; Return duct 4 bottoms and vacuum heat collection pipe 3 sealing UNICOMs, be provided with in the return duct 4 one be communicated with the water source and and return duct 4 between form the cold water pipe 5 of certain space, cold water pipe 5 bottoms are provided with the cold water down pipe 6 to each vacuum heat collection pipe 3 bottoms extension opening in parallel, form hot water rising passway 9 between cold water down pipe 6 and vacuum heat collection pipe 3 inwalls, return duct 4 tops are formed with water inlet pipe 103 UNICOMs of hot water outlet 8 and storage tank 1; The outside of return duct 4 is surrounded by certain thickness heat-insulation layer 7; But return duct 4 is made of bearing certain pressure, corrosion resistant metal material; Cold water pipe 5 is made of corrosion-resistant material; The external insulation layer 7 of return duct 4 is made of the polyurethane expanded material.

When cold water enters cold water pipe 5 from cold water inlet 10, enter in the vacuum heat collection pipe 3 along cold water down pipe 6, vacuum heat collection pipe 3 becomes heat energy with conversion of solar energy, water in the heating, vacuum thermal-collecting tube 3, and enter by the hot water rising passway 9 that forms between cold water down pipe 6 and vacuum heat collection pipe 3 inwalls in the certain space of formation between return duct 4 and the cold water pipe 5, because the pressure that cold water pipe 5 itself has a running water extrudes the hot water outlet 8 of return duct 4 with heated hot water, enter storage tank 1 and the outlet pipe 104 by storage tank 1 by water inlet pipe 103 and be transported to and use on the position.Therefore storage tank 1 can separate with heat collector 2, is installed on the suitable position, is not subjected to the influence of installation position.Certainly the user also can substitute storage tank 1 and using electricity wisely with electric heater with heat collector 2 UNICOM's electric heaters, does not reach when requiring when water temperature simultaneously, and available electrical heating water is to reach requirement.Certainly the user also can will be provided with electric heating element in the storage tank 1.Can establish simultaneously cold water inlet 10 UNICOMs of a return pipe 11 and cold water pipe 5 in storage tank 1 bottom, when the water temperature in the storage tank 1 descends, by return pipe circulation heating repeatedly in order again.Heat collector 2 is installed and can vertically be installed or laterally install according to mounting condition.
