| 20090114379 | HEAT EXCHANGER - A heat exchanger includes a discharge part formed by an opening part of a partition wall to facilitate discharge of oil, air and foreign substances from the interior of the heat exchanger. | 05-07-2009 |
| 20100243223 | EVAPORATOR - The present invention relates to an evaporator, and more particularly, to an evaporator which can restrict a surface area of a communication hole with respect to a cross sectional area of a compartment and a surface area of a tube with respect to a surface area of a fin, thereby providing a dimensional extent for maximizing the heat exchange efficiency. Therefore, by optimizing a relation between the surface area of the communication portion and the surface area of the compartment of the first header tank and dimensions for each surface area and the heights of the tube and fin, the present invention provides a dimensional extent for maximizing the heat radiation amount, reducing the maximum temperature deviation of the core portion and allowing the refrigerant and air to be smoothly flowed, thereby maximizing the heat exchange efficiency. | 09-30-2010 |
| 20110083466 | VEHICLE AIR-CONDITIONING SYSTEM EMPLOYING TUBE-FIN-TYPE EVAPORATOR USING HFO 1234YF MATERIAL REFRIGERANT - Provided is an air conditioning system with a tube-fin type evaporator which obtains optimal performance The air conditioning system with the tube-fin type evaporator using HFO 1234yf refrigerant, which has totally different physical properties from conventional refrigerant containing R-134, CO | 04-14-2011 |
| 20110100614 | HEAT EXCHANGER - One or more embodiments of the present invention relates to a heat exchanger. The heat exchanger comprises a pair of header-tanks having at least one partition wall and at least one baffle; a plurality of tubes; and a plurality of fins. A communication hole is formed on the partition wall that is positioned at a region disposed between the baffle and one end of the header-tank adjacent to the baffle. Given that a distance from the baffle to the one end of the header-tank is 100%, 1˜4 communication holes are formed at positions on the partition wall which corresponds to an extent of 0˜50%, 65˜100%, or an extent of 0˜50% and an extent of 65˜100%. | 05-05-2011 |
