Definitions

  • the present invention relates to a cooling device wherein the compressor's vibrations are prevented to be transmitted to the body.
  • the compressor In cooling devices, for example in refrigerators, the compressor generally operates in a chamber at the bottom of the body and is connected to the bottom surface on the base of the refrigerator cabin by four fixed legs.
  • Various types of elastic attenuators are used for connecting the compressor legs and transmittance of the vibrations generated during operation of the compressor to the body and the generation of noise is intended to be prevented.
  • the tubes that provide entry and exit of the refrigerant to the compressor are mounted to the evaporator and the condenser tubes by weld joints. Vibration attenuation rubbers are fitted on the connector tubes; however, these tubes can cause the vibration to increase both by the inertial effect and also from wrong positioning.
  • the aim of the present invention is the realization of a cooling device wherein the noise is reduced by preventing transmittance of the compressor's vibrations to the body.
  • the compressor is connected to the tubes coming from the evaporator and condenser and extending towards the compressor in the chamber wherein the compressor operates by means of inlet and outlets tubes.
  • the inlet tube is connected to the evaporator tube and the outlet tube to the compressor tube by means of a sliding coupling.
  • the sliding coupling connects the tubes aligning in the same axis and allows the tubes to move respectively within a certain distance, to move away, to move closer or to slide telescopically.
  • a sliding or roller radial bearing for the interconnected tubes to move freely, stoppers to prevent the tubes from being displaced and sealing elements preventing the refrigerant fluid flowing in the tubes from leaking out are provided.
  • the legs of the compressor are seated on a supporting plate that allows movement of a certain amount in each direction during operation.
  • the sliding couplings allow horizontal movement at the upper side of the compressor body, and the supporting plate at the lower side of the compressor body.
  • the compressor legs are seated on the supporting plate.
  • the legs and the supporting plate do not contact each other due to a ball placed therebetween or at least the legs can smoothly move slidingly on the supporting plate.
  • the ball can roll in a ball bearing between the legs and the supporting plate that is configured of two concave surfaces facing each other, wherein the radius of curvature of the surfaces is considerably greater than the radius of the ball and hence the compressor can move on the supporting plate to all sides in the horizontal direction.

  • Figure 2 - is the schematic view of a sliding coupling.
  • Figure 3 - is the schematic view of a compressor and the supporting plate.
  • the cooling device (1) comprises a compressor (4) that maintains the refrigeration cycle, having a casing (2) and more than one leg (3) secured under the casing (2), a condenser for condensing the refrigerant, an evaporator that cools by absorbing the ambient thermal energy, an evaporator tube (5) coming from the evaporator, an inlet tube (6) secured to the casing (2) for connecting the evaporator tube (5) to the compressor (4), a condenser tube (7) going to the condenser and an outlet tube (8) secured to the casing (2) for connecting the condenser tube (7) to the compressor (4).
  • the cooling device (1) of the present invention comprises at least one sliding coupling (9) that interconnects the evaporator tube (4) to the inlet tube (6) aligning to be in the same axis and/or the condenser tube (7) to the outlet tube (8) aligning to be in the same axis, allowing the evaporator tube (5) and the inlet tube (6) and/or the condenser tube (7) and the outlet tube (8) to respectively move away, move closer or to slide on each other telescopically.
  • the sliding coupling (9) comprises a sliding or roller radial bearing (10) that allows the tubes that are interconnected (5 to 6 and/or 7 to 8) to move smoothly therein.
  • the sliding coupling (9) comprises one or more stoppers (11) for the tubes that are interconnected (5 to 6 and/or 7 to 8) not to be displaced.
  • the sliding coupling (9) comprises one or more sealing elements (12) that prevent the refrigerant fluid flowing in the tubes (5, 6, 7, 8) from leaking out.
  • the vibrations generated during the operation of the compressor (4) are not transmitted from the inlet tube (6) to the evaporator tube (5) and from the outlet tube (8) to the condenser tube (7) that are interconnected by the sliding bearing (9) and since the evaporator tube (5) and the condenser tube (7) connected to the cooling device (1) body are not affected with the vibrations neither is the cooling device (1) body affected and the generation of noise is prevented.
  • the cooling device (1) comprises a supporting plate (13) on which the compressor (4) is seated allowing movement of the compressor (4) to all sides in the horizontal direction during operation.
  • the sliding couplings (9) allow movement in the horizontal direction at the upper side of the casing (2) and the supporting plate (13) allows at the lower side of the casing (2). Since the compressor (4) is not secured to the cooling device (1) neither from the upper part nor the lower part thereof, it can move on the supporting plate (13), for example to the right and left or to and fro, in the horizontal direction in a balanced manner without changing the vertical position.
  • the cooling device (1) furthermore comprises one or more balls (14) situated between the legs (3) and the supporting plate (13) preventing the contact of the legs (3) with the supporting plate (13) or at least having a diameter size allowing them to slide on one another, supporting the weight of the compressor (4) and maintaining the legs (3) and thereby the compressor (4) to move in the horizontal direction to all sides on the supporting plate (13) by making a rolling movement, and one or more ball bearings (15), one disposed on the leg (3) , the other on the supporting plate (13), configured of two symmetrical concave surfaces facing each other for housing the ball (14).
  • the radius of curvature of the surfaces forming the ball bearing (15) is considerably greater than the radius of the ball (14) and thereby the ball bearing (15) allows the ball (14) to move in small amounts to all sides in the horizontal direction between the concave surfaces, and hence the compressor (4) on the legs (3) can also move on the fixed supporting plate (13).
  • the operational frequency of the compressor (4) is attenuated and the pulsating flow, that can occur depending on the operational conditions, to be transmitted to the cooling device (1) body and the flow to stimulate the mechanical components for generating noise are prevented by allowing a certain amount of horizontal movement at the upper side wherein the inlet and outlet tubes (6, 8) are situated and at the lower side wherein the legs (3) and the connections are situated.

Abstract

La présente invention concerne un dispositif de refroidissement (1). Le dispositif comporte un compresseur (4) pour maintenir le cycle de réfrigération et fonctionne dans une chambre ; un tube d'entrée (6) fixé au boîtier (2) pour relier le tube d'évaporateur (5) au compresseur (4) ; un tube de sortie (8) fixé au boîtier (2) pour relier le tube de condenseur (7) au compresseur (4). Les tubes d'entrée et de sortie (7, 9) sont reliés aux tubes d'évaporateur et de condenseur (6, 8) au moyen d'un accouplement (9), ce qui évite de transmettre au corps les vibrations du compresseur (4).
