20120118548 | Plate Heat Exchanger - A plate heat exchanger realizing improved heat exchange performance by increasing the fluidity of fluids and by promoting turbulence of the fluids, including: heat exchange elements stacked by being laid one on top of another and individually formed by assembling upper and lower plates, with an internal flow channel defined in each of the heat exchange elements and an external flow channel defined between the heat exchange elements, the internal and external flow channels allowing internal and external fluids to pass therethrough, respectively, wherein the upper and lower plates are provided with respective wave patterns having ridges and valleys, each of the heat exchange elements has an inlet port and an outlet port, the upper and lower plates respectively have an upper flange and a lower flange which are assembled with each other through fitting, and first and second flat parts are formed around the upper and lower flanges. | 05-17-2012 |
20100287931 | MASTER CYLINDER FOR A VEHICLE - Disclosed herein is a master cylinder for a vehicle. The master cylinder includes a housing, a piston, inlet ports and a seal. The housing has therein a liquid pressure chamber to contain oil. The piston reciprocates in the liquid pressure chamber to control the pressure in the liquid pressure chamber. A front end of the piston has a stepped structure. The inlet ports are provided in the housing so that oil is supplied into the liquid pressure chamber through the inlet ports. The seal is seated into a seating depression which is formed in the inner surface of the housing. The seal opens or closes a flow path of the oil depending on whether the seal is brought into contact with the piston. The oil flows into the liquid pressure chamber along the stepped outer surface of the piston through a space defined between the piston and the seal. | 11-18-2010 |
20100270012 | AUTOMOTIVE HEAT EXCHANGER TO THE UNIFICATION OF HEADER AND TANK AND FABRICATING METHOD THEREOF - There are provided an automobile heat exchanger having a header formed integrally with a tank and a method of manufacturing the same, and, more particularly, an automobile heat exchanger comprising a top header pipe unit formed of a pair of header pipes and a bottom header pipe unit formed of a pair of header pipes, the top header pipe unit to be connected to top ends of tubes and the bottom header pipe unit to be connected to bottom ends thereof, and the header pipe including a header formed integrally with a tank. In the heat exchanger, each header pipe is manufactured in a welded type or folded type so that the header is formed integrally with the tank. Accordingly, unlike a conventional heat exchanger, the present invention does not require any separate metal mold or assembling means for assembling the header and tank. Consequently, the manufacturing cost is reduced and the manufacturing time is shortened by simplifying the processes. Furthermore, the pressure strength in the header-tank increases and the risk of leaking a heat exchanging medium decreases, to increase the efficiency of heat exchange. Further, the width wise sectional shapes of the top and bottom header pipe units are controlled so that the condensate generated on the surface of a plurality of the header pipes is easily discharged. | 10-28-2010 |
20090193827 | INTERNAL COOLING APPARATUS FOR AUTOMOBILES - An internal cooling apparatus for automobiles includes a first expansion valve for spraying a coolant to a main evaporator through a high-pressure pipe, a compressor receiving the coolant evaporated in the main evaporator through a low-pressure pipe, a condenser receiving the coolant compressed in the compressor, and a plurality of sub-evaporators each being installed inside of a seat to contact an automobile passenger. One end of each of the sub-evaporators is communicated with the high-pressure pipe and the other end thereof is communicated with the low-pressure pipe such that part of the coolant sprayed through the first expansion valve is supplied to the compressor via each of the sub-evaporators. | 08-06-2009 |
20090102297 | BLOWER MOTOR ASSEMBLY FOR VEHICLE - Disclosed herein is a blower motor assembly for a vehicle. The blower motor assembly comprises an armature assembly, a motor body, a magnet, an upper case, and a lower case. The armature assembly comprises a rotatable armature shaft with an armature. The motor body is an open cylinder that houses the armature assembly. The magnet is installed between the motor body and the armature assembly. The upper case has a through-hole which permits the armature shaft to projects outward through. The lower case is coupled to the upper case. The motor body is installed in an internal space defined by the coupled upper and lower cases. The motor body is fixed in a correspondingly-shaped hollow portion defined by a wall of a motor body fixing portion formed in the lower case. The magnet is fixed to a magnet fixing portion formed in the lower case. | 04-23-2009 |
