Definitions

  • This invention relates to a cooling device comprising a dryer in its cooling cycle.
  • a dryer between the condenser and the capillary tube is utilized in the cooling cycle to withhold the impurities in the circulating refrigerant fluid and to prevent these impurities from clogging especially the capillary tube and to absorb the moisture of the refrigerant fluid.
  • circulation of the refrigerant fluid may generate noise as a consequence of various reasons.
  • One of the most important reasons for this noise is the creation of a vortex or turbulence at the entrance to the capillary tubes by the refrigerant fluid which is in a liquid and gas phase in the dryer.
  • DE7638017U1 relates to a cooling device including a body for drying with a plate extending over the whole cross section.
  • the object of the present invention is to design a cooling device comprising a dryer which prevents noise by avoiding the formation of a vortex or turbulence during the circulation of the refrigerant fluid.
  • the cooling device (1) of the present invention comprises a compressor (2) providing the compression of the refrigerant fluid, a condenser (4) which condenses the refrigerant fluid leaving the compressor (2) as overheated vapour, making it first to pass into liquid-vapour phase then into liquid phase, one or more capillary tubes (5) providing the refrigerant fluid to attenuate and to entirely pass into the liquid phase, one or more evaporators (3) transmitting the condensed fluid, cooling the medium by absorbing heat of the medium and providing the refrigerant fluid to cool the cooling compartment by absorbing heat, and a dryer (6) situated between the condenser (4) and the capillary tubes (5), preventing the clogging of particularly the capillary tubes (5) by withholding the impurities contained within the refrigerant fluid circulating in the cooling cycle and absorbing the moisture in the refrigerant fluid (Figure 1).
  • the dryer (6) comprises preferably a cylindrical body (7), an inlet (8) which is attached to the outlet of the condenser (4) situated at one end of the body (7) and through which the refrigerant fluid flowing through the condenser (4) is transmitted, an outlet (9) attached to the inlet of the capillary tubes (5) providing flow of the refrigerant fluid into the capillary tubes (5), a filter group (10) situated between the inlet (8) and the outlet (9), withholding the impurities of various sizes and the moisture contained within the refrigerant fluid, and one or more plates (15) positioned between the filter group (10) and the outlet (9) situated on the inner wall of the body(7), preventing the creation of a vortex and turbulence by the refrigerant fluid flowing through the filter group (10) and reducing the noise caused by the vortex and turbulence to a minimum level ( Figure 2, Figure 3 , and Figure 4).
  • the plate (15) is positioned on the inner wall of the body (7), around the outlet (9).
  • the plate (15) comprises holes (16) of various sizes and numbers ( Figure 5 ).
  • the plate (15) comprises one or more bends (17) at different angles ( Figure 6 ).
  • the filter group (10) comprises a coarse filter (11) which receives the refrigerant fluid entering through the inlet (8) and withholds the larger sized impurities, one or more moisture filters (14) after the coarse filter (11) which entraps the moisture contained in the refrigerant fluid, and a fine filter (12) situated after the moisture entrapping filter (14) which withholds smaller sized impurities contained in the refrigerant fluid that the coarse filter (11) can not withhold.
  • the filter group (10) comprises one or more additional filters (13) positioned after the fine filter (12) and before the outlet (9) which withholds the smaller sized impurities that even the fine filter (12) cannot withhold ( Figure 7 ).
  • the section of the capillary tube (5) entering through the outlet (9) situated on the dryer (6) that is between the filter group (10) in the dryer (6) and the outlet (9) is bent with an angle preferably between 0 and 45 degrees.
  • the noise created due to vortex and turbulence is reduced to a minimum level ( Figure 8 ).
  • the noise created by the vortex and turbulence during the flow of the refrigerant fluid from the dryer (6) to the capillary tube (5) is reduced to a minimum level by utilizing the plate (15) situated in the dryer (6).

Claims (10)

  1. Dispositif de refroidissement (1) comprenant un compresseur (2) assurant la compression du fluide réfrigérant, un condenseur (4) à travers lequel passe le fluide réfrigérant sortant du compresseur (2) et un ou plusieurs tubes capillaires (5) et un sécheur (6) situé entre le condenseur (4) et les tubes capillaires (5), comprenant un corps (7), une entrée (8) fixée à la sortie du condenseur (4) d'une extrémité du corps (7) et à travers laquelle le fluide réfrigérant circulant à travers le condenseur (4) est transmis, une sortie (9) attaché à l'entrée du tube capillaire (5), fournissant le fluide réfrigérant pour s'écouler dans les tubes capillaires (5), un ou plusieurs groupes de filtres (10) situés entre l'entrée (8) et la sortie (9), retenir les impuretés de différentes tailles et l'humidité contenue dans le fluide réfrigérant, et une ou plusieurs plaques (15) positionnées entre le groupe de filtres (10) et la sortie (9), chaque plaque (15) s'étendant à partir d'une partie de connexion la paroi interne du corps (7) jusqu'à une extrémité libre à l'intérieur du corps (7), ladite ou lesdites plaques (15) empêchent la création d'un vortex et d'une turbulence par le fluide réfrigérant circulant à travers le groupe de filtres (10) à la sortie fixée à l'entrée du tube capillaire (5) et réduisant le bruit provoqué par le vortex et la turbulence à un niveau minimum.
  2. Dispositif de refroidissement (1) selon la revendication 1, caractérisé par un séchoir (6) comprenant des plaques (15) positionnées autour de la sortie (9), sur la paroi interne du corps (7) où le groupe de filtres (10) et le sortie (9) sont situés.
