Abstract

PURPOSE:To permit to increase the amount of humidifying by increasing the transferring amount of heat and preventing the reduction of enthalpy of water by a method wherein water is supplied to a water absorbing member, provided at the outer periphery of the heat pie, continuously while air is ventilated to the member to evaporate the water. CONSTITUTION:Water 5 in a tank 8 is sucked up to the water absorbing members 6 at the outer periphery of the heat pipe 6 continuously by capillarity and is evaporated at the upper part of the heat pipe 6 by contacting with the ventilated air from a fan 7 and, whereby, the movement of water is effected continuously. In this case, operating fluid, sealed in the heat pipe 6, is vaporized and moved to the upper part of the pipe, then, is condensed and returned to the lower part of the pipe, whereby the heat is moved continuously. Evaporating latent heat is deprived from the sucked water upon evaporation, however, the enthalpy of the water is increased by the heat transferred by the heat pipe 6 and the partial pressure of water vapor is increased whereby the amount of humidifying may be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heat pipe and a heat pipe added humidifier.

(Prior Art) A conventional heat pipe is equipped with fins on the outer periphery of its low-temperature end and/or high-temperature end to improve heat transfer between the heat pipe and the fluid outside the pipe.
Immerse the lower end of the humidifying net (03) in the fan (02).
4) allows ventilation to flow through the humidifying net (03), thereby evaporating moisture sucked up by the humidifying net (03) and humidifying the air. (05) is a tank (01)
There was a problem in that the water (02) was heated by the heater disposed in the water (02), and the effect of increasing enthalpy by the heater (05) was diminished as the water (02) was heated.

(Means for Solving the Problems) In view of the above, the present invention provides a heat pipe that can transfer not only heat but also moisture, and humidifies the air by exclusively utilizing the specific properties of this heat pipe. The first aspect of the invention is directed to a heat pipe characterized in that a water-absorbing member is provided on a part or the entire length of the outer periphery. Also, the second
The gist of the invention is a heat pipe equipped with a heat pipe, characterized in that water is continuously supplied to a water absorbing member provided on the outer periphery of the heat pipe, and at the same time, the water absorbed by the water absorbing member is evaporated by ventilation. It's in the humidifier.

(Example) An example of the first invention is shown in FIG. 1, in which a flocked body (2) as a water-absorbing member is provided on the outer periphery of a heat pipe (1). A second embodiment of the first invention is shown in FIG. 2, in which a porous member (3) as a water-absorbing member is provided around the outer periphery of a heat pipe (1). In Figures 1 and 2, (4) is a wick provided on the inner surface of the heat pipe (1), and a working fluid that can change phase is sealed in the sealed space inside the heat pipe (1). ing.

FIG. 3 shows a first embodiment of the second invention, in which a heater (8) is disposed in water (9) stored in a tank (5), and a heat nozzle (6) is installed. The bottom end is immersed. A water-absorbing member (6α) is provided on the outer periphery of the heat tube (6) over the entire length, and ventilation is provided from a fan (7) to the upper part of the heat pipe (6).

Therefore, the water (5) in the tank (1) flows through the heat pipe (
6) A water-absorbing member (
6α), the water is continuously sucked up by capillary action, and is evaporated on contact with the air ventilated from the fan (7) at the upper part of the heat pump (6), thereby causing continuous movement of water. Of course, some amount of water evaporates from the surface of the water absorption (5). The working fluid sealed in the heat tube (1) is heated at the lower part of the heat tube (1), evaporates, moves to the upper part, is cooled in the upper part, condenses, and returns to the lower part, and this process is repeated. In particular, heat moves continuously from the bottom to the top. Thus, the water absorbent member (6
The water sucked up by α) loses its latent heat of vaporization when it evaporates, but it is heated by the heat transferred by the heat pipe (6), its enthalpy increases, and the partial pressure of water vapor increases. The difference in water vapor partial pressure between the air and the air being sent increases, and therefore the amount of evaporation, that is, the amount of humidification increases.

A second embodiment of the second invention is shown in FIG. pipe (6
) are provided. Partition plate α of heat pipe (6)
A water-absorbing member (6α) is provided on the outer periphery of the portion located below the partition plate IG, but an annular fin (6b) is provided without providing a water-absorbing member on the portion located above the partition plate IlG. Or not. The total amount of air sent above or below the partition plate (11) can be changed by swinging the fan of the partition plate (10) which is pivotally attached to the power side end via pin A4. The rest of the structure is the same as that shown in FIG. 3, and corresponding members are given the same reference numerals.

Therefore, heat is radiated from the portion of the heat ξ eve (6) located above the partition plate 00, but since the water absorbing portion 41 (6a,) is not provided in that portion, moisture is radiated from there. It never evaporates. Therefore, by swinging the damper αυ to adjust the amount of air passing above and below the partition &uIJl, the amount of humidification can be finely adjusted.

FIG. 5 shows a third embodiment of the second invention, in which a heat pipe (6) is arranged so as to penetrate the partition plate Gη,
Low temperature air flows above the partition plate c3η, and the partition plate f
37) High temperature gas is flowing below. A water-absorbing member (6α) is provided on the outer periphery of the portion of the heat pipe (6) located above the partition plate θη, and this water-absorbing member (6α)
The water (33) stored in the tank l31) is continuously supplied through the nozzle device.The part of the heat pipe (6) located below the partition plate c3η has an annular fin (to).
is provided.

Therefore, when the water absorbed by the water-absorbing member (6α) evaporates, it takes away a large amount of latent heat, so the amount of heat transferred by the heat pipe (6) increases significantly.

(Operations and Effects of the Invention) As described above in detail with reference to the embodiments, in the first invention, since the water-absorbing member is provided over a part or the entire length of the outer circumference of the pipe, By evaporating the liquid sucked into this water-absorbing member, continuous transfer of the liquid becomes possible. Since a large amount of latent heat is taken away when the liquid evaporates, the amount of heat dissipated increases, and the amount of heat transferred by the heat pipe also increases.

In the second invention, water is continuously supplied to the water-absorbing member provided on the outer periphery of the heat pipe, and at the same time, the water absorbed by the water-absorbing member is ventilated to evaporate and humidify.
Not only water but also heat can be transferred to the water evaporation area at the same time, and therefore the enthalpy of water can be prevented from decreasing and the amount of humidification can be increased.
