The present invention relates to a noise reduction device for a heat exchanger for reducing the noise generated in the heat exchanger, and more particularly, it is formed integrally on the intake pipe and the exhaust pipe of the heat exchanger to which the fluid moves to occur on the intake pipe and the exhaust pipe The present invention relates to a noise reduction device for a heat exchanger that can effectively reduce noise.

A heat exchanger is a device that transfers heat from a fluid having a high temperature to a fluid having a low temperature through a heat transfer wall. The heat exchanger is used in a heater, a cooler, an evaporator, a condenser, and the like. The heat transfer medium used for giving heat is called a fruit (熱 媒), on the contrary, it is called a refrigerant (冷媒) used to take heat away.

The most commonly used type of heat exchanger is a metal tube with heat transfer wall, which includes cast type, double tube type, multi-tube type with tube type, and tube type type.

The double tube heat exchanger is composed of an inner tube and an outer tube, and heat exchange is performed between the fluid inside the inner tube and the fluid in the annular portion between the tube and the tube. This type of structure is simple but requires less processing. .

The large-capacity one uses a bushing type in which several small pipes are placed in a large external pipe, which flows in the same direction in the flow of high and low fluids in the same direction. What flows in a reverse flow direction and a perpendicular direction is called a cross flow type.

Common heat transfer media used in industry include water, steam, air, flue gas, petroleum, mercury, sodium, potassium, and dowtherm, a mixture of biphenyl ether and biphenyl.

Such a heat exchanger has a problem of noise generated by the fluid on the intake pipe and the exhaust pipe in the process of being introduced into the heat exchanger through the intake pipe and heat exchanged by the heat transfer medium and then discharged through the exhaust pipe.

Accordingly, an object of the present invention is to provide a noise reduction device for a heat exchanger, which is formed integrally on an intake pipe and an exhaust pipe of a heat exchanger through which a fluid moves so as to effectively reduce noise generated on the intake pipe and the exhaust pipe.

An object of the present invention described above is a noise reduction device body integrally installed on an intake pipe and an exhaust pipe of a heat exchanger device through which a fluid moves, a plurality of partitions installed inside the noise reduction device body, and the noise reduction device body. It is achieved by providing a noise reduction device for a heat exchanger comprising an inner wall and a sound absorbing member formed on the surface of the partition wall.

According to a preferred feature of the present invention, the sound absorbing member has an end portion formed in a wavy pattern so as to effectively absorb the noise generated on the noise reduction device main body and the partition wall.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to describe in detail enough to be able to easily carry out the invention by one of ordinary skill in the art, This does not mean that the technical spirit and scope of the present invention is limited.

1 is a cross-sectional view showing a schematic view of a noise reduction device for a heat exchanger according to an embodiment of the present invention, Figure 2 is a cross-sectional view of a noise reduction device for a heat exchanger according to an embodiment of the present invention, 3 is a cross-sectional view of a noise reduction device for a heat exchanger according to another embodiment of the present invention.

Noise reduction device 1 for a heat exchanger according to an embodiment of the present invention is the noise reduction device body 10 is integrally installed on the intake pipe 102 and the exhaust pipe 104 of the heat exchanger 100 to which the fluid moves. And a plurality of partition walls 20 installed inside the noise reduction device main body 10, and sound absorbing members 30 formed on the inner wall of the noise reduction device main body 10 and the surface of the partition wall 20. Include.

Here, the noise reduction device main body 10 is integrally installed on the intake pipe 102 and the exhaust pipe 104 of the heat exchanger 100, and the intake pipe 102 and the exhaust pipe 104 are connected to both sides, respectively. It will serve to form a plurality of partition walls 20 to be described later.

On the other hand, it is preferable that each of the noise reduction device main body 10 described above is mounted at a short distance within 1M from the heat exchanger 100 to effectively reduce the noise.

A plurality of partition walls 20 are formed in the interior of the noise reduction device main body 10 installed on the intake pipe 102 and the exhaust pipe 104, which are externally formed by the heat exchanger 100. In order to reduce the noise generated by reducing the flow rate of the fluid strongly introduced into the exhaust pipe 104 from the heat exchanger 100 to the intake pipe 102 or the heat exchanger 100 by the heat exchanger (100).

The partition wall 20 is formed alternately on the upper and lower wall surfaces of the noise reduction device main body 10 to form a path through which the fluid can pass. The flow rate of the fluid strongly entering and exiting the exhaust pipe 104 from the heat exchanger 100 into the exhaust pipe 104 by the heat exchanger 100 is reduced while passing through the path by the aforementioned partition wall 20.

The sound absorbing member 30 is formed on the inner wall of the noise reduction device main body 10 and the surfaces of the partition walls 20, which are strongly introduced into the heat exchanger 100 or from the heat exchanger 100. As it collides with the strongly discharged fluid, it serves to absorb noise generated from the noise reduction device main body 10 and the partition wall 20.

The sound absorbing member 30 may be formed of various materials such as porous fiber material, ceramic material, and synthetic resin material.

In addition, the sound absorbing member 30 described above has a sound absorbing member 30 having an end portion formed in a wavy pattern so as to effectively absorb noise generated on the noise reduction device main body 10 and the partition wall 20 as shown in FIG. 3. ') May be formed, or may be formed to have irregularities of various shapes.

Hereinafter, the overall noise reduction process of the noise reduction device 1 for heat exchangers according to an embodiment of the present invention will be described.

First, the fluid flowing strongly from the heat exchanger 100 through the intake pipe 102 passes through the noise reduction device main body 10, and the flow rate thereof is reduced, so that the noise is reduced, and the sound reduction device 30 reduces the noise. The noise generated in the main body 10 is absorbed.

The fluid introduced into the heat exchanger 100 through the intake pipe 102 undergoes heat exchange with the heat transfer medium flowing through the heat transfer medium intake pipe 106 and discharged through the heat transfer medium exhaust pipe 108, and then exhausts the exhaust pipe 104. It is strongly discharged through the noise reduction device while passing through the noise reduction device, thereby reducing the noise, and also absorbing the noise generated in the noise reduction device main body 10 by the sound absorbing member 30.

As described above, the noise reduction device for the heat exchanger according to the present invention is formed integrally on the intake pipe and the exhaust pipe of the heat exchanger to which the fluid is moved has an excellent effect that can effectively reduce the noise generated on the intake pipe and the exhaust pipe have.
