JPH0443874A - Vibration isolator in cooling system - Google Patents

Abstract

PURPOSE:To maintain vibration isolating effects over a long period by providing the delivery pipe of a compressor with a vibration-isolating cover around which a net made from plastic is wound, which delivery pipe is likely to vibrate in a cooling system. CONSTITUTION:A vibration-isolating cover 3 around which a net 4 made from plastic of polypropylene, polyethylene terephtalate etc., is provided around the outer periphery of the delivery pipe 2 of a compressor 1. The thixotropy phenomenon is thus eased and reduced even with softening of macromolecules due to high temperature and vibration and the vibration-isolating cover 3 is prevented from coming off the delivery pipe 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vibration isolator in a cooling system used in a refrigerator or the like.

2. Description of the Related Art Hereinafter, as a conventional example, a compressor that generates vibrations among piping of a cooling system will be described with reference to the drawings.

In Fig. 2, 1 is a compressor, 2 is a discharge pipe, and the compressor 1
It is connected to the. A vibration-proof rubber 6 covers the outer periphery of the discharge pipe 2. 7 is a bottom plate. Although the discharge pipe 2 is not shown, heat exchangers such as a condenser and an evaporator are connected through piping to form a cooling system.

In the above configuration, the high temperature and high pressure refrigerant gas compressed by the compressor 1 passes through the discharge pipe 2 to the condenser (not shown).
delivered to. At this time, the discharge pipe 2 vibrates due to the pulsation of the compressor 1 itself, causing noise. In order to prevent this vibration, a vibrating rubber 6 made of butyl rubber with a stickiness of about logarithm is attached to the discharge pipe 2 to reduce noise caused by resonance.

Problems to be Solved by the Invention In recent years, cooling systems used in refrigerators and the like have become larger and more efficient, and the vibrations generated in the piping of these cooling systems are increasing, and the temperature of the piping is increasing.

Therefore, in the above configuration, in a high-temperature usage environment such as in the summer, vibration of the discharge pipe 2 and softening of the vibration isolating rubber 6 itself may cause the vibration isolating rubber 6 to come off from the discharge pipe 2 if used for a long period of time. Therefore, there was a problem in that the vibration of the discharge pipe 2 further increased and noise was generated.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a vibration isolating device for a cooling system that can sufficiently exhibit a vibration isolating effect even in a high-temperature usage environment.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a cooling system comprising a compressor, a discharge pipe of the compressor, and a condenser or other heat exchanger connected to the discharge pipe. A vibration isolating device for a cooling system is provided in which a vibration isolating covering made of rubber or other polymer is provided around the outer periphery of the discharge pipe of the compressor, and the vibration isolating coating is made of rubber or other polymer and a net made of polypropylene, polyethylene terephthalate, or other plastic is wrapped around it.

Function As described above, in the present invention, by providing a vibration-proofing covering made of polypropylene, polyethylene terephthalate, or other plastic net around the outer periphery of the discharge pipe of the compressor, softening of the polymer and vibration due to high temperatures are prevented. The anti-vibration coating no longer comes off from the discharge pipe, and the thixo-hydroloby phenomenon is alleviated even when the anti-vibration coating is removed from the discharge pipe.

EXAMPLE Hereinafter, a vibration isolating device for a cooling system which is an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the vicinity of the compressor where vibrations occur in the cooling system. 1 is the compressor, 2 is a discharge pipe, and is connected to the compressor 1. FIG. A vibration-proof covering 3 is made of rubber or other polymer and is attached to cover the outer periphery of the discharge pipe 2. A net 4 is made of heat-resistant plastic such as polypropylene or polyethylene terephthalate, or other plastic, and is wrapped around the outside of the vibration-proof covering 3 to form a mesh having an interval of about 2 mm. The plastic net 4 is wrapped around the entire circumference of the vibration-proof covering 3 by utilizing its adhesive property and is integrated with the vibration-proof covering 3.

When a heat-resistant material such as polypropylene or polyethylene terephthalate is used as the plastic net 4,
The vibration-proofing effect no longer deteriorates up to an environmental temperature of about 150°C. This means that even if the vibration-proof covering 3 is softened and vibrated at high temperatures, the flow of rubber and other polymeric bones due to the thixotropic phenomenon is prevented, and the vibration-proof covering 3 is applied to the discharge pipe 2.
This is because there will be no deviation from it. Therefore, the vibration damping effect of the cooling system can be maintained for a long period of time.

Effects of the Invention As described above, the present invention provides a vibration-proofing effect over a long period of time by providing a vibration-proof covering made of a plastic net around the discharge pipe of a compressor, which is prone to vibration in the cooling system. We were able to provide a vibration isolator for certain cooling systems.
