Abstract

The present invention relates to a closed cooling tower using a cooling plate. It is to replace the existing type of cooling tower coil, fin coil or filler insert into a plate shape.

When used in an enclosed cooling tower, it can be divided into high and low temperature parts using several cooling plates. The cold plate increases heat exchange area, heat exchange time and heat exchange efficiency compared to conventional coils. In addition, it has a larger heat transfer area and heat transfer efficiency through processing shape and surface treatment. Plate-type closed cooling tower reduces the volume and weight of the sealed cooling tower and can increase the cooling efficiency. It also reduces the manufacturing process.

Description

Plate-type sealed cooling tower {PLATE TYPE CLOSED CIRCUIT TOWER}

The technology of the present invention relates to the field of heat transfer of mechanical engineering, and more specifically, to a heat exchanger having a coil or a coil wound with a heat exchanger, and a heat exchanger having a filler inserted therein, to increase the heat transfer time and heat transfer area. An alternative is a plate-type sealed cooling tower.

In general, heat transfer refers to heat transfer from a high temperature part to a low temperature part, and is classified into an open type and a closed type depending on whether a hot part and a cold part have a boundary. Hermetic uses conduction or radiation to transfer heat without the movement of the hot and cold parts. When conduction is used, the heat transfer efficiency varies greatly depending on the thermal conductivity, and thus a higher heat transfer material is used. If the same thermal conductivity material is used, the performance and efficiency of the heat transfer device depend on the heat transfer area.

The heat exchange part of the conventional hermetic cooling tower is manufactured in the form of a coil, a combination of coils and cooling fins, or a filler inserted in the middle of the coil, which has a limitation in improving the performance and efficiency of the hermetic cooling tower.

The object of the present invention is to provide a cooling plate having a high heat exchange performance and efficiency by increasing the heat exchange area and increasing the heat exchange time of the heat exchange portion of the hermetic cooling tower.

The heat exchange part of the hermetic cooling tower for achieving the present invention as described above is characterized in that the plate.

In addition, a spacer and a water distributor are mounted to facilitate water distribution and air flow.

Hereinafter, the plate-type closed cooling tower of the present invention will be described with reference to the accompanying drawings.

The cooling plate of the plate-type closed cooling tower allows the reference surface to form a curved surface in the transverse direction (X) and the longitudinal direction (Y) to increase the heat exchange area. In addition, it is possible to increase the heat exchange area to the fine projection shape or the bear shape (5) through the surface treatment.

In order to facilitate the distribution of water in the production of a plate-shaped water distribution device (6) is installed so that the circulation of the circulation water smoothly so as not to resist the cooling water distribution. In addition, a uniform spacer 7 is mounted on the plate to make the flow of air uniform. The heat exchanged coolant is collected in the sump (8) in the plate heat exchanger and discharged to the outlet pipe.

The heat exchange part of the conventional hermetic cooling tower was manufactured by inserting a coil, a combination of a coil and a cooling fin (2), or a filler (3) in the middle of the coil. When it is replaced with the cooling plate 4, the heat exchange area and heat exchange time of the cooling water and the circulating water are increased, thereby improving the performance and efficiency of the hermetic cooling tower.

Plate-type closed cooling tower of the present invention having the configuration and function as described above has the following effects.

The cooling plate of the plate-type closed cooling tower has a curved reference surface to increase heat transfer area and heat transfer time in both the low temperature and high temperature parts, thereby increasing heat transfer performance and efficiency.

In addition, the surface heat transfer area is increased to increase the heat transfer performance and efficiency of the sealed cooling tower.
