Description

Heat exchanger for solar thermal power generation and heat collection
Technical Field
The present invention relates to a heat exchanger for solar thermal power generation and heat collection, and more particularly, to a heat exchanger for solar thermal power generation and heat collection configured to be capable of generating power while efficiently transferring radiant heat of solar energy to a heat medium through a heat pipe (heat pipe).
Background
Generally, fossil fuels such as petroleum, coal, and natural gas are widely used as energy sources in accordance with the development of human society, but recently, the demand for new renewable energy sources has been increasing due to problems such as environmental pollution and exhaustion of fossil fuels.
Solar energy is one of the new renewable energy sources, called an infinite energy source, and is used in real life by heating and hot water supply using radiant heat, or by converting solar energy into electric energy, or the like.
The heating by using the radiant heat of the solar heat is widely used in a manner of mainly using a heat pipe and a heat collecting plate.
For example, korean patent publication No. 10-0934122 discloses a technology regarding a vacuum tube type solar collector module that improves heat exchange efficiency and is easy to assemble and maintain.
The vacuum tube type solar collector module includes: a evacuated tube solar collector and a manifold, wherein the evacuated tube solar collector comprises: a vacuum glass tube; the heat collecting plate is arranged inside the vacuum glass tube and is used for collecting solar heat; and a heat pipe (heat pipe) having a predetermined region provided inside the vacuum glass tube, and having a condensation portion formed on one side thereof protruding from the outside of the vacuum glass tube, the condensation portion having a working fluid enclosed therein. The manifold includes: a heat medium main pipe in which a heat medium that exchanges heat with a condensation portion of the heat pipe is formed so as to be long in a longitudinal direction, and in which a hollow portion is formed at upper and lower sides in a direction perpendicular to the longitudinal direction, and in which only a predetermined region of the condensation portion is penetrated; and a heat exchange portion having a tubular shape connected to the hollow portion and configured to be inserted into the condensing portion.
However, in the conventional solar collector module constructed as described above, since the heat medium main pipe through which the heat medium flows is formed of a single passage, it is difficult to further improve the heat exchange efficiency as the time in which the circulated heat exchange medium contacts the condensing part becomes short.
In addition, as the heat pipe is disposed across the center of the passage of the main heat medium pipe, resistance increases and scaling may occur when the heat medium flows, thus easily causing a decrease in heat exchange performance.
Further, since a three-way stretching operation of forming a hollow portion in the heat medium main pipe is required in order to connect the condensation portion of the heat pipe and the heat medium main pipe, the manufacturing is troublesome, and the structure becomes complicated, the number of parts increases, and defects such as water leakage of the welded portion are highly likely to occur as the heat exchange portion is separately provided between the condensation portion and the hollow portion and then welded.
Korean patent publication No. 10-1467391 discloses a technology of a heat exchanger for solar heat collection, which includes: a heat pipe in which an evaporative liquid is enclosed; and a heat exchange tube to which the plurality of heat pipe side ends are connected in a state of being inserted, and in which a first heat exchange flow path and a second heat exchange flow path through which a heat medium exchanges heat with the heat pipe side ends and moves are formed in the heat exchange tube, respectively, wherein the plurality of heat pipes are arranged at a predetermined interval.
The heat exchange pipe is made of an aluminum extruded material, a plurality of assembly holes are formed at a predetermined interval in a longitudinal direction in a cross-sectional center, one side end portion of the heat pipe is assembled to the plurality of assembly holes, and the first heat exchange flow path and the second heat exchange flow path are respectively formed at both sides of the plurality of assembly holes in the longitudinal direction with the assembly holes and the partition wall interposed therebetween.
By configuring as described above, it is possible to provide a heat exchanger for solar thermal power generation and heat collection which is easy to manufacture, can reduce manufacturing costs due to reduction in components, and is excellent in sealability and can improve heat exchange performance.
On the other hand, in the conventional heat exchanger for solar heat collection, since power generation is not performed, there is a problem in that a separate power generation device needs to be provided.

The heat pipe 10 may be implemented in the same structure as a heat pipe that is generally widely used, and thus a detailed description thereof will be omitted.
An evaporative liquid such as alcohol is enclosed in the heat pipe 10.
As shown in fig. 8, by the heat collecting plate 6 provided inside the vacuum glass tube 4 of the solar collector 2, the evaporative liquid inside the heat pipe 10 is heated and evaporated, and is condensed and radiated at one side end portion of the heat pipe 10.

As shown in fig. 1 to 7, the heat exchange flow paths 23 may be formed in a pair on both sides of the heat exchange tube 20.
In addition, as shown in fig. 10, the heat exchange flow path 23 may be formed only on one side of the heat exchange tube 20.

The heat dissipation plate 50 may be configured to be disposed in a state of being exposed to the atmosphere, and perform heat dissipation by being in contact with the atmosphere.
If the heat dissipation plate 50 and the heat dissipation fins 54 are formed and provided in the manner as described above, heat generated when the thermoelectric element 40 generates electricity can be efficiently dissipated, thereby maintaining high power generation efficiency.
