At present, in order to realize that solar water heater combines with building, the separated type solar water heater that generally adopts water tank and heat collector branch to be arranged is placed on heat collector on the pitched roof of Chaoyang, on the balcony, perhaps be suspended on the wall on the sunny side, and water tank be placed on indoor.Like this, just can not influence the attractive in appearance of building.But the heat successor water tank for heat collector is obtained generally has three kinds of modes.A kind of is to adopt water pump with carrying out forced circulation between heat collector and the water tank, and the heat of heat collector is in time sent in the water tank.This method also will increase parts such as expansion drum, safety valve, control instrument, thereby cost is higher owing to increased water pump.Another kind method is exactly to adopt the method for Natural Circulation, utilizes the characteristics that hot water density is little, cold water density is big, utilizes two tube connectors that heat collector and water tank are coupled together and carries out the Natural Circulation heat exchange.Because the power of Natural Circulation is very little, the flow resistance of tube connector is big, and heat dissipation capacity is big, thereby the non-constant of heat-transfer effect.
The third mode couples together water tank and heat collector by connecting heat pipe exactly.The condensation segment that connects heat pipe stretches in the water tank, and evaporator section stretches in the heat collector.All place a heat pipe in the heat collector in each thermal-collecting tube, the condensation segment of these heat pipes is connected with the evaporator section that connects heat pipe.We know that heat pipe comprises evaporator section and condensation segment, although it is to take out interior air earlier and inject a certain amount of working medium, package closure are formed again.During its work, outside heat spontaneous evaporation section is imported into, makes the working medium heat absorption evaporation in the evaporator section become steam and flow to condensation segment, and condenses at condensation segment, discharges gasification latent heat, spreads out of outside the pipe.Liquid working substance under condensation segment condenses flows back to evaporator section again.So continue circulation, constantly heat is passed to the other end from an end of heat pipe.By heat pipe, the solar thermal energy that obtains in the thermal-collecting tube is passed to the evaporator section of heat pipe, by heat pipe the heat energy that obtains is passed in the water tank again.This mode is lower than first kind of mode cost, and is more far better than second way heat-transfer effect.But this kind mode is defectiveness also, because used more heat pipe, thereby cost still is higher.In addition, give the connection heat pipe, still have the heat transfer loss's in the middle of this by the adopting heat pipes for heat transfer in the thermal-collecting tube.
Summary of the invention
The technical problem that the utility model solves is exactly to adopt the higher and bigger problem of heat transfer loss of separated type solar water heater cost of heat pipe.
A kind of separated type solar water heater comprises water tank, heat pipe, and heat pipe comprises into split type condensation segment and evaporator section, and condensation segment extend in the water tank, and evaporator section is connected by three-way cut-off valve with condensation segment.Finned tube in the heat collector is exactly the evaporator section of heat pipe, and connecting tube is exactly the condensation segment and the changeover portion of heat pipe.When dispatching from the factory, will vacuumize in the heat pipe evaporator section, and charge into working medium by three-way cut-off valve.Like this, heat collector, connecting tube, water tank can separately be packed, and are convenient to transportation.During installation, need earlier connecting tube to be linked to each other with three-way cut-off valve, the air in the condensation segment is extracted out by the technology mouth on the three-way cut-off valve with vavuum pump then, again the screw rod in the three-way cut-off valve is back-outed, three-way cut-off valve is opened, the condensation segment of heat pipe is communicated with evaporator section.Three-way cut-off valve belongs to prior art, and the three-way cut-off valve that uses on its structure and principle and the split-type air conditioner is identical.
As further improvement, be connected with three-way cut-off valve after the evaporator section parallel connection of many heat pipes, be connected with fin (being called finned tube) at the evaporator section outer surface of heat pipe.Many finned tubes can be worked simultaneously to absorb heat; Fin can increase endotherm area.Surface at fin is coated with coating for selective absorption.
It is in the rectangular box of transparent material that many above-mentioned finned tubes can be arranged on a upper surface.Rectangular box is convenient to and architecture-integrals such as roof, balcony, exterior wall, outward appearance neat appearance.
For above-mentioned arbitrary separated type solar water heater, the changeover portion of connecting tube comprises bellows.Bellows is convenient to bending, and the more convenient body of wall that passes is installed.
When the evaporator section of heat pipe is vertically placed, working medium in the evaporator section is because the gravity effect may accumulate in the bottom of evaporator section, cause the part evaporator section may not have liquid working medium and influence heat-transfer effect, in order to prevent this situation, the imbibition core can be set at the inwall of evaporator section, because of the adsorbable liquid refrigerant of imbibition core, can guarantee that so whole evaporator section has liquid refrigerant.When heat pipe evaporator section becomes level or tilts to place, the phenomenon that the part evaporator section may not have liquid working medium can not take place, so need not to be provided with the imbibition core.
