Abstract: PROBLEM TO BE SOLVED: To provide a cooling apparatus, which is capable of preventing a cold air from being transmitted to a bearing of a fan, and capable of reducing noise and stably maintaining a storage chamber at a predetermined temperature.SOLUTION: The fan 13 for sending a cold air of a cooler 11 is provided with a heat insulating material 18 with a shape that is equal to a boss diameter of an axial flow fan 14 or smaller than that of the fan 14 at a motor support unit 16. Thereby, a temperature of the bearing of the axial flow fan 14 is prevented from being decreased by the cold air, so that the temperature of the bearing of the axial flow fan 14 is hardly decreased even if the interior of a refrigerator is in a low temperature atmosphere. Accordingly, the oil viscosity of the bearing of the axial flow fan 14 is prevented from going up, thereby preventing the contact sound of the fan 13 and the occurrence of a constraint state due to an increase of a sliding resistance.

Abstract: PROBLEM TO BE SOLVED: To solve such problems that there is a need to make the plate thickness of an airtight container larger in order to secure resistance to pressure when welding is performed between a cup-shaped metal body of an airtight terminal and the airtight container of an compressor operated under high pressure, that rigidity remains at a high level even when pressurization processing associated with resistance welding is performed, that an improvement in adhesion caused by an elastic deformation can not be expected, that penetration on the weld connection surface becomes unstable or non-welding exists in some parts, and that there is a possibility of the occurrence of a quality defect such as leakage.
SOLUTION: By increasing the roughness on the weld connection surface of the cup-shaped metal body of the airtight terminal, the weld connection surface of the cup-shaped metal body adjusts to the connection surface of the airtight container by the pressurization during welding, and stable current-carrying welding can be performed. Because of this, the depth and width of penetration necessary for resistance to pressure can be stably secured, and quality can be stabilized.

Abstract: PROBLEM TO BE SOLVED: To sufficiently deliver gas-liquid separated gas from an external delivery pipe 39, by substantially restricting and treating a refrigerant 27 and oil 6.
SOLUTION: Refrigerant gas 27 including the oil 6 is delivered from a delivery port 18, and passes through a stator passage 37 after passing through a rotor passage 36, and is delivered outside a sealed vessel 1 by passing through the external delivery pipe 39 arranged in a part above a position of a stator upper chamber 38 of a sealed vessel 1 after passing through to the stator upper chamber 38 on the outer periphery of a connecting passage 34, but the refrigerant gas 27 including the oil 6 collides with a gas-liquid separating collision wall 100 by arranging the gas-liquid separating collision wall 100 on the periphery of the external delivery pipe 39 as Fig. 1 so that the refrigerant gas 27 including the oil 6 is not delivered as it is outside the sealed vessel 1, and the oil 6 sticks to the gas-liquid separating collision wall 100, and only the refrigerant gas 27 is delivered outside the sealed vessel 1, and gas-liquid is efficiently separated.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor having enhanced reliability in its sliding portions by enhancing the lubricating performance in the outer periphery of a turning scroll and that of a non-turning scroll. SOLUTION: Crowning process is applied to the edge of the outer corner of an oil supply groove located in the non-turning scroll, thereby secures the lubricating performance when contacting with the periphery of the turning scroll to lead to enhancement of the reliability of a compressor. Further, in order to avoid collision with a turning scroll supporting member, the corner of the sliding surface of the turning scroll plate is chamfered to generate a shape with obtuse angle, which can further enhance the reliability of the compressor.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor, in which sealability of a cock installed to a swirl scroll is improved and a cork made from an inexpensive material can be used therefor. SOLUTION: The cock 13 is installed on an outer peripheral side of a swirl end plate 7b of a communicating hole 16, at a position closer to the outer peripheral side than a part in which a swirl spiral blade 7a of the swirl end plate 7b is formed. Therefore, since temperature rise is small on a side closer to the outer periphery than the part in which the swirl spiral blade 7a of the swirl end plate 7b is formed, little deformation is caused by heat expansion of the swirl end plate 7b and the cock 13 near the part provided with a cock mounting part 24 even in operation, and thereby a screw part is not loosened and sealability of a bearing surface 23 is not degraded.

Abstract: PROBLEM TO BE SOLVED: To handle a coolant 27 and an oil 6 while that are virtually constrained, and to enable a gas which has been sufficiently separated into vapor and liquid to be discharged from an external discharge pipe 39.
SOLUTION: A coolant gas 27 containing an oil is discharged from a discharge port 18, passes through a rotor passage 36, and subsequently passes through a stator passage 37. Then, the coolant gas 27, after coming out of a stator upper section chamber 38 at outside circumference of a connection chamber 34, is discharged to the outside of the sealed vessel 1 passing through an external discharge pipe 39 provided at a portion higher than the location of the stator upper section chamber 38 of a sealed vessel 1. Then, the oil 6 is made to be hard to come up the inner wall surface of the sealed vessel 1 by providing a concave and convex 5 processing on the inner wall surface of the sealed vessel 1, and is prevented from being discharged to the outside of the sealed vessel 1, so that oil 6 adhered to an inner wall surface of the sealed vessel 1 may not come up the inner wall surface of the sealed vessel 1, and may not be discharged to the outside of the sealed vessel 1 as it is. As a result, only the coolant 27 is discharged to the outside of the sealed vessel 1 thereby subjecting the oil to vapor liquid separation with good efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor using a natural refrigerant R744 for generating high pressure in a compression chamber, improved in efficiency and durability by keeping the dimensional accuracy of a clearance between the bottom face of a fixed scroll and the lap upper face of a turning scroll to optimize the amount of oil supply. SOLUTION: An oil supply terminal portion slope 18 having a slope at two or more stages is formed at a terminal portion of the lap upper face of the turning scroll, and an oil supply opening 17 of an oil supply passage 16 is opened to the oil supply terminal portion slope 18. Thus, the machining of the slope is stabilized and the amount of oil supply into the compression chamber is stabilized, thus improving efficiency and securing durability. COPYRIGHT: (C)2011,JPO&INPIT
