[0002]
[Prior art]
An example of a conventional steam trap water heater is disclosed in Japanese Patent Publication No. 4-67080. By providing a discharge pipe and upper and lower water reservoirs at the outlet of the steam trap and allowing the re-evaporated steam to pass through the upper water reservoir and cool it, the steam that has become dull can be extinguished.
[0003]
[Problems to be solved by the invention]
In the conventional steam trap water heater, there is a problem that it is impossible to reliably extinguish the steam that has become moy. That is, in the above-mentioned conventional one, the steam is cooled by passing it through the water in the water reservoir, condensed and extinguished, but when the temperature of the accumulated water rises, it evaporates and the water in the water reservoir is As a result, the steam that has become smoky cannot be removed reliably over a long period of time.

DETAILED DESCRIPTION OF THE INVENTION
Many types of heat pipes are used for a wide range of applications as heat transfer means. Any heat pipe having an excellent heat transfer capability can be used, but a so-called loop type heat pipe is suitable. A loop type thin tube heat pipe accommodates a working fluid for heat transport in a loop type thin tube formed in a loop shape, and a part of the loop type thin tube is used as a heat absorbing part and a part other than the heat absorbing part is used as a heat radiating part. Thus, it has a thin shape and excellent heat transfer capability.
[0007]
By forming a condensate chamber with a water heater air vent casing communicating with the outlet of the steam trap and the heat absorption part of the flat heat pipe, a condensate reservoir is provided at the bottom of the condensate chamber. The high-temperature condensate discharged from the outlet flows into the condensate chamber, temporarily accumulates in the condensate reservoir, and is absorbed and cooled by the heat-absorbing unit while being discharged from the communication hole into the atmosphere. The absorbed amount of heat is quickly transmitted through the heat pipe, and is radiated to the atmosphere from a heat radiating portion disposed outside the water heater / air conditioner casing.
[0008]
By absorbing the heat of the high-temperature condensate discharged by the heat pipe, a large amount of heat is absorbed quickly, and the re-evaporation of the condensate can be suppressed and the generation of moist water can be reliably prevented.
[0009]
【Example】
As shown in FIG. 1, a steam trap water heater is composed of a hollow cylindrical water heater casing 1, flat loop heat pipes 2, 3, 4, and condensate reservoirs 12, 13, 14. Configure. The inlet portion 5 of the casing 1 is communicated with an outlet of a steam trap (not shown).
[0010]
In the present embodiment, an example in which disk-shaped loop type thin tube heat pipes 2, 3, and 4 are used will be described. The heat pipes 2, 3, and 4 have different diameters, and the diameters are sequentially increased from the inlet 5 toward the lower side. The loop type thin pipe heat pipes 2, 3, and 4 partition the inside of the water vaporizer casing 1 into three condensate chambers 6, 7, and 8, and each condensate chamber 6 through the communication holes 9, 10, and 11 , 7, 8 are communicated.
[0011]
The communication holes 9, 10, 11 are formed by pipes having a predetermined length penetrating the respective heat pipes 2, 3, 4, and the communication hole pipes 9, 10, 11 are attached by increasing the length sequentially. . Only the length of the communicating hole pipes 9, 10, 11 protruding above the heat pipes 2, 3, 4 is the head height of the condensate reservoirs 12, 13, 14. That is, the condensate flowing into the condensate chamber 6 from the inlet portion 5 once accumulates in the condensate reservoir 12 and then overflows the upper end of the communication hole pipe 9 and flows down to the condensate chamber 7 below. It will flow down.
[0012]
The communication hole 11 at the bottom of the lowermost condensate chamber 8 is opened in the air atmosphere. The positions of the communication holes 9, 10, 11 provided in the heat pipes 2, 3, 4 are decentered inside the casing 1, so that the condensate flowing in from the inlet portion 5 causes the communication holes 9, 10, 11 to pass through. Do not flow linearly and continuously through.
[0013]
In the present embodiment, an example in which the condensate reservoirs 12, 13, and 14 are formed based on the lengths of the communication hole pipes 9, 10, and 11 is shown, but the condensate reservoir is formed by, for example, sequentially reducing the communication hole diameter. Alternatively, a float valve or a check valve that opens at a predetermined water head height may be disposed on the communication hole.
[0014]
Moreover, in the present Example, the example which provided the communication holes 9, 10, and 11 in the heat pipes 2, 3, and 4 was shown, respectively.
[0015]
In the present embodiment, an example in which three heat pipes 2, 3, and 4 are attached is shown. However, according to the amount of condensate flowing into the casing 1 and the amount of heat, the flat plate heat pipe is 1 It is possible to use only a single sheet or a larger number of plural sheets.
[0016]
Of the loop type thin pipe heat pipes 2, 3, and 4, a portion located inside the casing 1 is a heat absorbing portion, and a portion located outside the casing 1 is a heat radiating portion. Although the inside of the loop type thin pipe heat pipes 2, 3 and 4 is not shown in the figure, a large number of thin pipes are formed in a loop and in parallel to form a single continuous thin pipe, and the inside is evacuated to supply the working liquid. Enclosed.
[0017]
A predetermined amount of high-temperature condensate discharged from the steam trap first accumulates in the condensate reservoir 12 of the condensate chamber 6 from the inlet 5 of the casing 1, and the amount of heat held by the condensate is absorbed by the heat absorption part of the heat pipe 2. Is done. The condensate in the condensate chamber 6 overflows from the upper end of the communication hole 9, flows down to the lower condensate chamber 7, is absorbed by the heat pipe 3, and further overflows from the upper end of the communication hole 10 to return to the condensate chamber 8. The condensate that has flowed down and absorbed by the heat pipe 4 and has finally fallen in temperature overflows the communication hole 11 and is discharged into the atmosphere.
[0018]
The amount of heat of the condensate absorbed by the heat absorption parts of the loop type thin pipe heat pipes 2, 3 and 4 is thermally transferred in the heat pipes 2, 3 and 4 and radiated from the heat radiation part outside the casing 1 to the atmosphere. . In this way, the heat generated by the condensate is quickly and efficiently dissipated into the atmosphere by the loop-type thin tube heat pipes 2, 3, and 4, so that the condensate re-evaporates and the steam rises up. It can be surely prevented.
[0019]
【The invention's effect】
As described above, in the present invention, once the condensate is temporarily stored in the condensate reservoir at the bottom of the condensate chamber, the heat held by the condensate can be efficiently absorbed by the heat pipe, and the re-evaporation of the condensate can be performed. It is possible to reliably prevent the generation of steam that is moist and suppressed.
