CONSTITUTION:A first holding member 61 for holding a heat collecting pipe 3 at a required position in a vacuum tube 1 and a second holding member 62 for fixing the pie 3 and a reflector member 5 to each other are made by bending a wire having resiliency. The first and the second holding members 61, 62 have turns 61a, 62a, respectively, the diameter of which is smaller than the outer diameter of the heat collecting pipe 3 in the state that no pressure is acted thereto but becomes greater than the outer diameter of the pipe 3 when pressure is applied thereto. A pair of straight parts 61b are extended from the opposite ends of the turn 61a, and sililarly a pair of straight parts 62b are also extended from the opposite ends of the turn 62a in a unitary manner. The straight parts 61b of the first holding member 61 are shaped to conform to the internal configuration of the vacuum tube 1 so that they are held in contact with the inner surface of the vacuum tube 1 for supporting the pipe 3 at a required position in the vacuum tube 1.

These pawls 62c are inserted into mating holes 51 formed in the reflector member 5 at the portions thereof near the opposite open ends.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a solar heat collection system that enables intermediate temperature heat collection of about 160 to 200 degrees Celsius by installing a heat collection member and a reflection member for concentrating sunlight on the heat collection member in a vacuum tube. The present invention relates to a device for supporting a heat collecting member and a reflecting member.

This conventional? As shown in Figures 7 and 8, the means for supporting each member of the J-heating device can be housed in a sealing board stem that seals the open end of the vacuum tube (A) or supported through the waiting vibrator (C). The holding part assembly (E) that holds the tip of the heat collecting pipe (which becomes the heat collecting member) is made of a vacuum tube (C7 wire rod 1) made of a wire that is in contact with the 11 sides of the tube and a drop welded to its center. It consists of a rod (Hoe 2), and this hanging rod (Hoe 2) is used as a heat collecting pipe). In addition, the reflective member (g) and the heat collecting pipe) means that both ends of the connecting rod (1) made of wire are made into a large heat collecting pipe) and the reflective member (g) -, N (su) (rumored). .Here, I assembled the reflective member (G) and the holding member (E) with the man (for field work, go to the heat collecting pipe by inserting frrJ into the vacuum tube (A) in advance). These are then inserted and assembled into the vacuum tube (A) circle, but when they are inserted, they may be cut from the U part of the tube, and there are many blank spots, which causes problems in workability. When the membrane is exposed to the moon, this is not the case at the +j part, and if the reverse VCM selective absorption membrane is exposed to N, the selective absorption membrane is burnt out, which in any case leads to a decrease in heat collection efficiency.

The present invention was made in view of the above-mentioned problems, and is designed to support a heat collecting member and support between a heat collecting member and a reflecting member without using any means. A heat collecting member for collecting light, a reflecting member for collecting sunlight on the heat collecting member, and a wire rod having spring properties is bent to apply pressure to the outside of the heat collecting member. The outer diameter of the heat collecting member is smaller than the outer diameter of the heat collecting member by applying sweat, and is inserted with several holding members that form a winding portion that tightens the heat collecting member. Some of the several holding members are integrally formed from the winding part so that the extending wing rod contacts the inner surface of the vacuum tube to support the heat collecting member at a predetermined position within the vacuum tube, and remains. The holding member reflects the tip of the wing rod f114
The present invention provides a solar heat collector that is attached to a shrine so that the energy from the reflecting member is concentrated on the heat collecting member.

By using VCT, it is possible to support the heat collecting member at a predetermined position within 1' of true seam without soldering N, and it is possible to fix the heat collecting member and the reflecting member to each other in a precise positional relationship, etc., which facilitates assembly work. is easy. Furthermore, since there is no porosity, the heat collecting member can be provided with a uniform selective absorption film.

The above embodiment of the present invention will be explained based on FIGS. 1 to 6 VC.
When it comes to IT, a transparent vacuum tube made of glass or the like is sealed with a sealing plate (2) at its opening, and (3) is a support pipe placed inside the plate (2) that is supported through the seal. It is a heat collecting pipe that serves as a heat collecting member inserted into the vacuum tube (1), and the outer end protruding from the sealing plate (2) has a heat/magnetic exchanger (4) consisting of a dual purpose pipe and a side!
This is the conclusion. The heat exchange WG 14J passes through a passage VC through which a heat medium such as water flows through the inner frame (4a), and connects the outer tube (4b) and the heat collecting vibrator (3J).

Then, the heat collecting pipe ill and the outer pipe (4b) of the heat exchanger (4)
) The cylinder is evacuated and a working fluid that changes into two phases, such as Freon, is sealed inside. Therefore, the part of the heat collecting pipe (3) located inside the vacuum tube (1) becomes an evaporation part, and the working fluid is evaporated by sunlight, and the part i is the outer pipe (4b) of the heat converter (4). This heats the heat medium that is compressed and flows inside the inner tube (4a). (5) is a reflective member for concentrating sunlight on the heat collection pipe (3), and has a parabolic cross section with -F lumi deposited on the surface of an aluminum substrate.

tfillM consists of a first holding member that holds the heat collecting pipe (3) in a predetermined position on the vacuum tube (1) circle, and a holding member that fixes the heat collecting pipe (3) and the reflecting member (5) to each other. In the state where the wire rod that softens the springiness is bent and no pressure is applied, a pressure smaller than the outer diameter of the heat collection pipe +3J is applied, so that the winding part (6I

The rod (61b) of the vacuum tube (11) is matched to the circumferential shape of the vacuum tube in order to contact the inner peripheral surface of the vacuum tube (11) and support the heat collecting pipe (3) at a predetermined position of the vacuum tube. 61a
) always acts to tighten the heat collecting pipe (3), and the wing pieces (61b) work to press against the inner cylinder surface of the vacuum tube (1), so that the heat collecting pipe f3J is reliably held in the specified position. Ru. A pair of wing rods (62b) of the second holding part 6 are equipped with a retaining claw (62b) at the tip of each to hold the reflective member (5) between the heat collecting pipes (3J) at predetermined positions (to hold the thread). 620
), and this locking claw (620) is held in the rest hole (51) provided at both open ends of the reflective capital U (51). (62a) is also constantly working in the direction of tightening the heat collecting vibrator (3).
When inserting the locking claw (62C) in b) into the locking hole 61) of the reflection member t!'jl, the opening end of the reflection member (5) should be
E-shrink it to make it smaller and then lock it.

Therefore, if VC pressure is applied to the winding part (62a), the second holding member (621) becomes rotatable relative to the heat collecting pipe (3), so the position of the reflecting member (5j) can be easily set and corrected. Once the positional relationship is determined, it is likely to shift due to the tightening N force of the winding part.

Furthermore, even if the heat collecting pipe expands and contracts due to heat collection and its outer diameter changes in size, the winding portion responds to the VC, so the tightening N force will not loosen and the positional relationship between the two will not shift.

In addition, selective absorption membranes also have the effect of facilitating tCJ deposition.
