Embodiment approach 1

[0036] This embodiment is a representative embodiment of the heat exchanger stack support described in claims 1, 2, and 3, the packing unit described in claims 4, 5, and 6, and the heat exchange tower described in claim 8.

[0037] exist figure 1 (a), Figure 2, image 3 , Figure 4 , Figure 5Among them, the heat exchange tower 10 is filled with filler units A layered up and down in its frame. The filler unit A includes a closed heat exchanger 11 and a corrugated-plate-shaped filler 13 made of synthetic resin, and a plurality of fillers 13 are arranged side by side at intervals in the width direction of the external air inlet 14 . The plurality of straight pipe portions in each of the aforementioned hermetic heat exchangers 11 are parallel to each other, and are arranged substantially in parallel in the width direction of the external air inlet 14 .

[0038] The spray water sprayed on the packing unit A is directly contacted with the external air flow, and the spray water ...

Embodiment approach 2

[0059] Structures and functions different from Embodiment 1 are as follows.

[0060] exist figure 1 (b) In the present embodiment shown on one side, each filler unit A has a multi-layer closed heat exchanger 11 on the top and a filler 13 on the bottom. On the straight pipe part 12 of the multi-layer closed heat exchanger 11 in the packing unit A of the upper layer, all the spreading water is in contact with a straight pipe part of a certain layer of the upper and lower layers at least once, in the case of 4 layers shown in the figure , in contact with at least two layers, in fact at least three times with the straight pipe portion 12, and then flow to the filling member 13 below, under the direct contact with the external air flow accompanied by the flow, and the effect of latent heat generated by evaporation Next, the spreading water is cooled.

[0061] This action is repeated in each layer of filler unit A.

[0062] The spreading water is made to flow onto the filler 13 i...

Abstract

PROBLEM TO BE SOLVED: To stably support a straight pipe part in a heat exchanger by removably attaching spacers assembled in a vertical hierarchical state to a strut of a cooling tower via a common frame.

SOLUTION: A shape material 15 attached to the sequentially uppermost closed type heat exchanger is slid in its longitudinal direction with respect to a shape material 15 attached to an adjacent lower closed type heat exchanger by latching of a recessed part 15b and a flat part 15a, and it is drawn to a cooling tower exterior from an outside air inlet side. Scales, slime or the like adhered to the closed type heat exchanger is removed, and it is replaced by a new one when it is damaged.

Description

technical field [0001] The present invention relates to a heat exchanger group support, a packing unit using the heat exchanger group support, and a closed heat exchange tower filled with the packing unit. Background technique [0002] Regarding this packing unit, various types of structures have been developed and manufactured, and among them, the applicant has manufactured a hermetic heat exchanger of the following structure. [0003] When manufacturing a cooling coil that connects straight tubes with a U-shaped tube having a U-shaped bend to form a circulating cooling water path meandering in the plane direction, the ends of adjacent straight tubes are brazed with the U-shaped tube. Previously, tube spacers having a U-shaped cross section were temporarily passed on these tubes as spacers, and the tube spacers were placed in a state where the tube spacers were located near the center of the aforementioned tube group, and the ends of adjacent tubes were brazed by means of t...
