Abstract
The utility model relates to a convective typed solar energy water heater with vacuum tubes, and comprises a vacuum heat collecting tube, a big water tank and a light reflecting plate. The two ends of the heat collecting tube are all provided with openings, and the lower end is connected with an in-out water pipe. Because of the frequent flow of the in-out water, the fouling of the heat collecting tube is avoided. Simultaneously, a shielding cover is used to shield one or a plurality of heat collecting tubes, so a convective channel is formed in the whole system. The thermal efficiency and the service life of the utility model are improved.
Description
The utility model relates to a kind of solar vacuum-tube water heater field.
Present many solar vacuum-tube water heaters of producing, vacuum tube directly contacts with water, and after long-time the use, easy fouling in the vacuum tube causes the thermal efficiency of vacuum tube to descend.Chinese patent ZL95239732.3 " single flow solar vacuum-tube water heater " adopts and to install water-supply-pipe additional prevent the vacuum tube fouling in vacuum pipe inner cavity, and still, this method makes water heater internal structure complexity, and dismounting is inconvenient.
The purpose of this utility model is the shortcoming that overcomes the easy fouling of thermal-collecting tube in the prior art, provide a kind of simple in structure, thermal-collecting tube is less scaling, the convection type solar vacuum-tube water heater that the thermal efficiency is high.
Technical solution of the present utility model is:
A kind of convection type solar vacuum-tube water heater comprises vacuum heat collection pipe, large water tank, reflector, the equal opening in thermal-collecting tube two ends, and its lower end communicates with a water inlet pipe and water outlet pipe.
Can set up a little water tank in the thermal-collecting tube lower end, water inlet pipe and water outlet pipe is installed on a side of little water tank.
Also can in little water tank, place cotton-wool class material.
The utility model adopts the equal opening in thermal-collecting tube two ends, and its lower end communicates with water inlet pipe and water outlet pipe, because the frequent of Inlet and outlet water flows, avoided the thermal-collecting tube fouling, simultaneously, set up radome, shield one or several thermal-collecting tube in use, make to form convection channel in the whole system, thereby improved the thermal efficiency and service life.
Fig. 1 is an overall structure schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment:
A kind of convection type vacuum tube water heater, comprise large water tank 1, the top of large water tank 1 has blast pipe 7, the side has overflow pipe 6, large water tank 1 is supported by support 4, reflector 3 is fixed in the side lower part of large water tank 1, the vacuum heat collection pipe 2 of several equal openings in two ends is installed on it, the thermal-collecting tube upper end communicates with large water tank 1, the lower end connects a little water tank 8, and water inlet pipe and water outlet pipe 5 is installed on a side of little water tank 8, and a radome is set above thermal-collecting tube 2, shield one or several thermal-collecting tube in use, with the convection current of fortified water.In use, also can place some cotton-wool class materials in little water tank (8), so that absorb dirty matter, this cotton-wool class material can be changed at any time.
