Description

Cooling tower with reduced noise}

The present invention relates to a cooling tower with reduced noise, and more specifically, to a cooling tower with reduced noise implemented to minimize the generation of noise that may be generated during the cooling process.

Generally air conditioning equipment and refrigeration. Refrigerators or industrial heat exchange devices operated in refrigeration equipment generate waste heat that must be removed, and in order to remove this waste heat, the waste heat must be released into the atmosphere using a cooling medium. The cooling method of the cooling tower is divided into air cooling, which performs sensible heat cooling by forced convection of atmospheric air, which has a temperature lower than the fluid to be cooled, and evaporative cooling, which cools using the latent heat of evaporation caused by contact between cooling water and air. This type of cooling tower is widely used because it has a greater cooling effect and is more economical than any other cooling device.

A typical cooling tower is a counter flow type cooling tower in which air flows vertically upward and cooling water flows vertically downward, and a cross flow type cooling tower in which air flows almost horizontally and cooling water flows vertically downward. It is divided into a cooling tower, and the flow method of the cooling water is an open type in which the cooling water and air evaporate and exchange heat while flowing through an open filler, and an open type in which the cooling water (coolant or refrigerant) flows into the pipe on the outer surface of a closed cooling coil. It is divided into a closed type that exchanges evaporative heat while contacting air.

In terms of ventilation methods, there is a suction ventilation type that sucks in and discharges high-temperature air that has completed heat exchange while passing through a heat exchange unit (such as a filler or heat pipe), and a suction ventilation type that presses and vents external air toward the heat exchange unit and releases the high-temperature air that has completed heat exchange. It is classified as a press-in ventilation type that discharges through the exhaust port.

Here, while the suction ventilation cooling tower forms a heat exchange area with a side casing (wall) and an upper casing (roof), the pressure ventilation cooling tower usually forms a heat exchange area with only the side casing, and the upper front is an exhaust port. In general, the casing consists of a single-panel casing made of synthetic resin or steel.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .

The inner housing 5251 is formed in a cylindrical shape forming a sealed internal space and is installed inside the lower part of the seating block 521, and is formed in the pillar seating groove 522 by vibration or impact transmitted from the rotation support unit 530. The support fluid 523, which is compressed by the middle support pillar 541 that vertically descends along, is received from the pillar seating groove 522 and received from the upper side.

Here, a fluid movement path (not shown in the drawing for convenience of explanation) may be installed between the pillar seating groove 522 and the inner housing 5251 to relay the movement of the support fluid 523.

The support partition 5252 divides the inner space of the inner housing 5251 into an upper space where the support fluid 523 is accommodated and a lower space forming a sealed space where the partition support spring 5253 is installed. 5251) is installed on the break.

The partition support spring 5253 is installed on the lower side of the inner space of the inner housing 5251 and supports the lower side of the support partition 5252.

The lower support portion 520 having the above-described configuration supports the middle support portion 540 moving vertically up and down, and at the same time, the middle support portion 540 moves up and down due to vibration or impact transmitted to the middle support portion 540. It may perform a buffering function such as vibration or shock during the discharge or introduction of the support fluid 523, which is compressed when moving in the vertical direction.

The above-described embodiments are for illustrative purposes, and those skilled in the art will recognize that the above-described embodiments can be easily modified into other specific forms without changing the technical idea or essential features of the above-described embodiments. You will understand. Therefore, the above-described embodiments should be understood in all respects as illustrative and not restrictive.
