Problems solved by technology

However, when it is desired to lengthen the flow path for performance improvement, etc., it is necessary to adjust the length in the vertical direction, resulting in a change in the height of the product
In addition, there is also a method of reducing the diameter of the resin tube and increasing the number of tubes, but the inside of the tube may be clogged by the surface tension of condensed water, and there is a problem of performance degradation in the case of clogging

Embodiment approach 2

[0073] In this embodiment, the same components as those in Embodiment 1 are assigned the same symbols and their descriptions are omitted. Figure 9 It is a figure of the end part of the resin tube 25 of the heat exchanger 11 which concerns on one Embodiment of this invention. Embodiment 2, such as Figure 9 As shown, the end portions of the resin tubes 25 b of the down flow path 13 b connected to the lower end side mounting plate 27 are formed in chamfered shapes 35 .

[0074] The condensed water may clog the inside of the tube 25 due to the surface tension of the condensed water, and this clogging problem can be prevented by enlarging the diameter of the resin tube. However, when it is desired to arrange a plurality of tubes with small cross-sectional areas in order to improve the performance of the heat exchanger, it is necessary to consider the problem of clogging the ends of the tubes due to the size of the tube diameters. In order to avoid this problem, the shape of the...

[0078] In this embodiment, the same components as those in Embodiment 1 or 2 are assigned the same symbols, and their descriptions are omitted. Figure 11 It is a cross-sectional view of the communication channel part 20 and the channel partition plate 22 of the heat exchanger 11 according to one embodiment of the present invention, (a) is an external view of the heat exchanger, and (b) is viewed from the direction of arrow F-F Figure 11 Sectional view of line F-F (same as line G-G) in (a), (c) is viewed from the direction of arrow G-G Figure 11 Cross-sectional view of G-G line in (a).

[0079] Such as Figure 11 (b), shown in (c), the flow path dividing plate 22 can be installed and disassembled to change the installation position, and the drain port 15 that is located at the inlet side communication channel portion 23 and the drain port that is located at the outlet side communication channel portion 24 Between 16 and 16, the ratio of the number of resin tubes 25 constit...

Embodiment approach 4

[0084] In this embodiment, the same components as those in Embodiments 1 to 3 are assigned the same symbols and their descriptions are omitted. Figure 12 It is a plan view viewed from the side of the fluid flow path 13 of the upper end side mounting plate 26 of the heat exchanger 11 mounted in the dehumidifier 1 according to the embodiment of the present invention, and an enlarged view of main parts inside the circle H and the circle I . As shown in the figure, body mounting claws 36 are provided on both side surfaces of the upper end side mounting plate 26 . in addition, Figure 13 It is a plan view seen from the side of the fluid flow path 13 of the lower end side mounting plate 27 of the heat exchanger 11 mounted in the dehumidifier 1 according to the embodiment of the present invention, and an enlarged view of the main part inside the circle J. As shown in the figure, a body mounting claw portion 37 is provided on the side surface of the lower end side mounting plate 27...

Abstract

A heat exchanger comprises an introduction opening (12) for introducing fluid containing a condensation component, a plurality of hollow fluid channels (13) for passing the fluid introduced from the introduction opening (12) and exchanging heat between that fluid and heat exchanging fluid flowing the outer part, a lead-out opening (14) for leading out the fluid flowing through the fluid channel (13) to the outside, and discharge openings (15, 16) for discharging the fluid condensed in the fluid channel (13) to the outside. The fluid channel (13) has a plurality of pipes (25a) forming upward channels through which the fluid flows upward, and a plurality of pipes (25b) forming downward channels through which the fluid flows downward, wherein the cross-sectional area of each pipe (25a) forming the upward channel is set larger than that of each pipe (25b) forming the downward channel.

Description

technical field [0001] The present invention relates to a heat exchanger and a dehumidifier using the heat exchanger. Background technique [0002] Most heat exchangers of conventional dehumidifiers use resin structures. In the heat exchanger formed by the blow molding method, a plurality of condensed passage pipes in the vertical direction and a condensed passage pipe in the horizontal direction are provided (for example, see Patent Document 1), or the heat exchanger is composed of a plurality of resin pipes ( or pipeline) constitutes (for example, see patent document 2). In these heat exchangers, the fluid to be condensed is taken in from the upper part of the heat exchanger, and it moves toward the discharge part of the fluid to be condensed at the lower part, so that the flow direction of the fluid to be condensed is aligned with the falling direction of the dew condensation fluid, thereby improving the condensation efficiency . [0003] Patent Document 1: Japanese Pa...
