Abstract

PURPOSE:To increase the heat collecting efficiency of a water heater, by effectively utilizing the solar rays received by heat collecting plates and by transferring heat to a hot water tank as soon as possible, even when the weather repeatedly changes from fine to cloudy weather, by constituting the water heater so that the press-fitted parts of heat collecting plates which are respectively divided into a plural number are collected to the evaporating part of a heat pipe. CONSTITUTION:The condensing part 3'b in the upper part of the evaporating part 3'a of a heat pipe 3' is dipped in water 11 in a hot water tank 2a. A heat collecting plate part 4'' is composed of a plurality of heat collecting plates crossing at right angles with the heat pipe 3. Each heat collecting plate is composed of a rising part 4'a being inscribed in a transmitter body 9, a heat collecting surface 4'b to receive solar heat, a heat transfer part 4'c forming a suitable slope, and a contacted surface 4'd being press-fitted to the evaporating part 3'a of a heat pipe 3'. The heat collecting plates are concentrated and contacted with the evaporating part 3'a of a heat pipe 3' being interposed by the contacted part 4'd, so that heat from the solar rays can be always supplied to an operating liquid 12 by 100%. On the other hand, the length of a heat pipe 3' is enough to be about 2/3 shorter than the length of a hea collecting plate part 4' so that an evaporation-condensation cycle can be performed at faster speed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a heat pipe type solar water heater that utilizes a heat pipe as a heat transfer means.

Conventional configuration and its problems This type of solar hot water problem is configured as shown in FIG. In other words, 1 is the main unit of the Hayabusa V, 2 is the hot water tank installed above the Hayabusa heater, 3 heat pipes is 4. is the heat collecting plate crimped to the 4 heat pipes 3, and the 3 corners are Evaporation section of heat pipe 3, 3b heat pipe 3
This is the condensation part of In such a conventional heat pipe type solar water heater, the plurality of heat pipes 3 are all extended L7 to the lowest end of the heat collecting plate part 4 and have an A1ζ configuration, so that the heat collecting plate part 4 receives sunlight. Afterwards, the working fluid in the evaporating section 38 of the heat pipe 3 is boiled, the heat of evaporation is removed, and the fluid is conveyed to the compressor m3b.

However, especially when changing from a clear sky to a cloudy sky (JJ% meeting changes from cloudy to clear), the boiling of the working fluid in the evaporator section 3g is caused by the heat collection, which is the part enclosed in the f-sill 111 fluid power cylinder. Only the solar radiation to the lower part of the plate part 4 becomes (T effect,
There is a deficiency in that the solar part is not being used effectively.In other words, the solar radiation to the upper part of the rod plate part 4 is due to the latent heat of evaporation even if heated 17, because the working fluid is not sealed in that part. This is because it is impossible to take away the In addition, once evaporation begins and the solar radiation continues, the working fluid liquefied in the condensing part 3b is heated and re-evaporated in the upper part of the heater while flowing down in the heat pipe 3. Solar radiation to the upper part of the heat collecting plate will also be effectively utilized. As described above, conventional heat pipe type solar water heaters cannot be said to have good thermal efficiency under weather conditions that alternate between clear skies and swampy skies.

Purpose of the Invention The purpose of the present invention is to solve the above-mentioned conventional problems.
Even when the weather repeatedly changes from sunny to cloudy, the solar radiation received by the Hayabusa slats is effectively used. Our goal is to provide pipe-type solar water heaters.

Structure of the Invention This invention is characterized in that the heat collecting plate section is divided into a plurality of parts and arranged above the 'I'd exit part of the heat pipe, and that the heat collecting plate part is crimped between the plate and the heat pipe by the evaporation of the heat pipe. It is concentrated in the department. As a result of this measure, 1) when the sky changes from clear to cloudy, only the solar radiation to the bottom of the heat collecting plate as explained in the conventional example can be effectively used when switching from dull to clear. All of the energy flowing to the upper part of the heat collecting plate is collected in the -F pipe evaporation part, so under any solar radiation conditions, all the solar radiation to the heat collecting plate is absorbed by the working fluid in the heat pipe. In addition to being utilized for evaporation, the length of the heat pipe can be shortened with the above configuration, so that the steam is transported to the condensing section and the condensed liquid is returned to the evaporating section quickly. Saisuru t becomes active.

The evaporation cycle of the i-power liquid 12 is faster than that of the conventional one, and the heat collecting plate 4' having a negative V number is discontinuously disposed inside the heat collecting body in the direction perpendicular to the heat pipe plate 1'. By partitioning the space to form the partition wall ■, it is possible to suppress the convection of the internal air that occurs as the temperature inside the Hayabusa β device body 18 rises, and it also has the effect of eliminating heat dissipation due to convection. In addition, the effect of improving the efficiency of the small group is brought about.

Effects of the Invention In the heat pipe type 11J% thick water heater of the present invention, all the floating plates are in concentrated contact with the V sheath part 3n of the heat pipe 3, so that all the transmitted sunlight flows into the working fluid 12. When heated, the Hayabusa Pg11 ratio decreases to -1. Since the penetration of the heat pipe 3 can be shortened, the evaporation-condensation cycle becomes faster and the heat transfer cycle becomes more active! There is a P. As an embodiment, since the heat collecting plate 4 is configured to intermittently partition the inside of the actual component body 1, air convection can be suppressed and convection heat radiation can be eliminated.
