Abstract
The present invention discloses an outer buckled type thermoelectric cell which is used for supplying power for a cold and heat measuring meter. A transducer group (2) and a matched radiator (3) are fixed on the platform surface of a heat-collecting block (1). After the thermoelectric cell is fixed to a heat supplying pipeline, the heat of hot water in the pipeline is transmitted to the transducer group by the heat-collecting block, the afterheat is emitted into peripheral space by the radiator which is tightly stuck to the cold surface of the transducer group, and both surfaces of the transducer form temperature difference. Owing to the Seebeck effect of a thermoelement, the output end of the transducer group generates thermoelectromotive force transformed by an electronic module. When the thermoelectromotive force achieves rated voltage, a suitable operating power supply is supplied to the cold and heat measuring meter. When low-temperature water flows in the pipeline, a power supply can also be supplied to the cold and heat measuring meter. Because the thermoelectric cell is a solid state device, the operation of the thermoelectric cell has the advantages of long term, continuity, safety and stabilization.
Description
Technical field
The present invention relates to a kind of exterior buckle type thermoelectric cell, belong to the physical power source technical field for the hot-cold measurer power supply.
Background technology
Applicant of the present invention once proposed a kind of duct type hot-cold measurer thermoelectric generator in its previous Chinese patent application 99105498.9 and 99207907.1, this thermoelectric generator is to cooperate realization concentrated supply of heating in the city, household metering to charge and the supply unit of invention.It is to utilize that hot water generates electricity as thermal source in the pipeline, has simple in structure, duration of work and need not add advantages such as other energy, Maintenance free, long working life, use cost are low, belongs to the environmental protection power supply.
Because the heat source tube of the heat source body of above-mentioned duct type thermoelectric generator must be connected in series into heat supply pipeline, is suitable for installing the initial construction stage of heat supply pipeline.If in existing heating system, use the power supply of duct type thermoelectric generator instead as hot-cold measurer, heat source tube is connected in series into heat supply pipeline need changes pipeline, difficulty of construction is bigger.And the manufacturing cost of heat source tube accounts for 1/3～1/2 of the whole cost of duct type thermoelectric generator, and weight accounts for 1/2～2/3 of overall weight.To alleviate the weight of thermoelectric generator greatly if can cancel heat source tube, reduce its manufacturing cost.In addition, the Voltage stabilizing module that boosts that above-mentioned thermoelectric generator adopted, though can successfully be applied to the hot-cold measurer of more domestic manufacturer production, but be applied to Danfoss, during the hot-cold measurer of companies such as Ka Mulupu, also there is a problem: just beginning the heat supply stage, because the heat-collecting block temperature rises gradually, thereby the output voltage of electric organ also is to rise to the voltage stabilizing value that sets gradually, the neither one transition stage, can not satisfy the requirement of single-chip microcomputer " electrification reset ", thereby need add a normally closed sensitive switch at the output of thermoelectric generator, behind output voltage stabilization, press sensitive switch, realize " electrification reset " of single-chip microcomputer, could guarantee the operate as normal of hot-cold measurer.
Summary of the invention
Purpose of the present invention is exactly at the problems referred to above, a kind of exterior buckle type thermoelectric cell as the hot-cold measurer power supply is provided, it utilizes the exterior buckle type heat-collecting block that is fixed to the heat supply pipeline outer wall to gather heat, by thermoelectric transducer group and boost voltage stabilizing and electronic switch module, can be long-term, safety, provide stable working power for hot-cold measurer continuously.
The object of the present invention is achieved like this: for the exterior buckle type thermoelectric cell of hot-cold measurer power supply is made up of heat source body, thermoelectric transducer group, radiator, sealed insulation layer and electronic module.Its heat source body is to be made of the exterior buckle type heat-collecting block 1 that is fixed on the heat supply pipeline outer wall, fixedly thermoelectric transducer group 2 and supporting aluminium alloy heat radiator 3 on the heat-collecting block 1, at its perimeter bond plastic septum 4, in the cavity that heat-collecting block 1, radiator 3 and dividing plate 4 surround, inject the polyurethane blowing agent, form the sealed insulation layer 5 of a densification, and with electronic module 6 be sealed in the thermal insulation layer after the thermoelectric transducer group is connected, with lead the outside thermoelectric cell that hot-cold measurer is used that constitutes is received in the output of electronic module 6.The one side of exterior buckle type heat-collecting block 1 is a platform, can lay thermoelectric transducer group 2, another side is the circular arc semi-cylindrical, with heat supply pipeline outer wall tight connecting, its four jiaos are respectively stretched out a fritter that through hole is arranged, and can be fixed on the pipeline with 4 bolts and metal cassette tape.
When hot water flow (during heat supply) is arranged in the pipeline, or there is water at low temperature to flow (during cooling), because the effect of radiator, it is poor to have uniform temperature on the two sides of thermoelectric transducer group, thereby just can generate electricity, and the conversion of process electronic module, for hot-cold measurer provides suitable working power.
Provide technology to compare with previous Chinese patent application 99105498.9 and 9920790.1, the present invention except have equally safety, Maintenance free, can long-term continous-stable work, help the characteristics such as environmental protection, also have the following advantages: (1) is convenient to install: adopt 4 bolts at any time thermoelectric cell to be installed on the pipeline, need not to change original pipe network, easy construction; (2) volume-diminished 1/2, weight saving 2/3; (3) the exterior buckle type thermoelectric cell does not directly contact the high pressure heat transfer medium, has saved withstand voltage cost input; (4) because materials are saved and the simplification of manufacturing procedure, make the complete machine cost can reduce half; (5) possess the function that powers up of instantaneous starting, guarantee single-chip microcomputer " electrification reset ".
