JPS5823100Y2 - Cooling coil device for closed cooling tower - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling coil device in a closed cooling tower.

The cooling coil device conventionally installed in this type of cooling tower is
If the equipment is assembled into a large unit and the cooling coil needs to be replaced at the end of its service life, it must be removed from the tower, transported, and new equipment installed in the tower. This had the disadvantage that it was extremely troublesome and required a lot of effort and time.

The purpose of the present invention is to eliminate such conventional defects, and the cooling coil 1 is meanderingly bent in the vertical direction, and an appropriate number of support rods 2 are integrally attached across the meandering portion. A plurality of cooling units 3 are vertically arranged at appropriate intervals on a beam 6 installed horizontally in a closed cooling tower 40 chamber 5, forming a flat panel cooling unit 3. The lower ends of the support rods 2 of the units 3 are removably connected to each other, and the upper ends of the support rods 2 of the adjacent units 3 are connected to each other, so that both ends of the cooling coils 1 constituting each unit 3 are piped into the chamber 5, respectively. The air conditioning process fluid circulation pipe 10.10 is removably connected and connected to the air conditioning process fluid circulation pipe 10.10.

Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 designates a cooling coil, which is bent in the vertical direction, intersects the meandering portion of the plurality of stages, and connects an appropriate number of support rods 2 into one body at the intersection with the cooling coil 1, thereby forming the cooling coil 1.
A cooling unit 3 in the form of a flat plate panel was constructed by the supporting rods 2 and 2.

Reference numeral 4 denotes a closed type cooling tower, in which a plurality of cooling units 3 are arranged vertically at appropriate intervals on a horizontal beam 6 installed in an internal chamber 5, and the supporting rods 2 of each unit 3 are arranged vertically at appropriate intervals. The lower end is removably attached to the beam 6, and the plate 7 at the upper end of the support rod 2 of the adjacent units 3 is connected to fix each unit 3 immovably, and the cooling unit 3 is Both ends of the cooling coil 1 to be formed were removably connected to a circulation pipe 10.10 for an air conditioning process fluid disposed in the chamber 5 of the cooling tower 4.

In the drawing, 8 is an eliminator provided to cover the upper opening of the cooling tower 4 to capture water droplets, 9 is a water spray pipe provided below the eliminator, and 11 is an air intake port provided at the bottom of both sides of the cooling tower 4. Air from outside was forced into the tower.

In the above device, water from the lower water tank inside the tower 4 is pumped up, the water is jetted out from the sprinkler pipe 9 to wet the cooling unit 3, and outside air is introduced into the tower from the air intake port 11 by driving the fan 12. The internal process fluid is cooled by exchanging heat with the wet water on the surface of the cooling unit 3 to cool the cooling unit 3, and the internal process fluid is circulated through the circulation pipe 10 to the air conditioner. In the cooling system according to the invention, a flat panel cooling unit 3 is formed by a meanderingly bent cooling coil 1 and a support rod 2, and a plurality of them are arranged in parallel. By removing the water pipes 9 and opening the upper part of the tower 4, each cooling unit 3 is installed on the beam 6 using a crane or the like, and the upper ends of the support rods 2 of adjacent units 3 are connected to each other. As a result, it can be easily assembled into the tower, and it is also easy to disassemble the cooling unit 3 one by one and take it out of the tower, making the replacement work very simple and easy to transport.
