| 20100122978 | HIGH-CAPACITY PTC HEATER - A high-capacity positive temperature coefficient heater, may include a plurality of positive temperature coefficient rods, wherein each of the positive temperature coefficient rods has a built-in positive temperature coefficient element that generates heat when electric power is supplied thereto, a plurality of heat-radiating fins attached to either side of the positive temperature coefficient rods along a longitudinal direction thereof, an upper housing coupled to one ends of the positive temperature coefficient rods, and a lower housing coupled to the other ends of the positive temperature coefficient rods, wherein the heat radiating fins are bonded to the positive temperature coefficient rods by heat conductive adhesive. | 05-20-2010 |
| 20100140245 | Positive Temperature Coefficient (PTC) Rod Assembly and PTC Heater Using the Same - A positive temperature coefficient (PTC) rod assembly is provided for a PTC heater. PTC elements and an electrode terminal to which an insulator is attached may be retained in a channel-shaped rod cover having an open side so as to be exposed to the outside, and a heat-radiating fin is in direct contact with one surface of the rod cover so as to conduct heat, and another heat-radiating fin may be in direct contact with one surface of the insulator attached to an outer surface of the electrode terminal so as to conduct heat, so that the PTC rod assembly minimizes empty space in an inner space of the rod cover, increases heat transfer efficiency, and is easily manufactured due to a simple structure and reduction in the number of parts. | 06-10-2010 |
| 20100140255 | Positive temperature coefficient heater - A positive temperature coefficient heater may include at least one positive temperature coefficient rod having a heating module inserted into a rod case made of brass and plated with tin, at least one heat-radiating fin made of brass, plated with tin, and contacted and coupled with each of opposite outer faces of the positive temperature coefficient rod, and upper and lower housings coupled to opposite longitudinal ends of the positive temperature coefficient rod, wherein the positive temperature coefficient rod and the heat-radiating fin are joined together by soldered portions. | 06-10-2010 |
| 20110061400 | HEAT EXCHANGER HAVING THERMOELECTRIC ELEMENT - A heat exchanger may include a housing including an intake port through which air is introduced into the housing from outside, a seat inlet supplying air to a vehicle seat, and an exhaust port through which a portion of the air introduced from outside is exhausted from the housing to outside, a blower unit mounted inside the housing and operated by a first motor to supply the air introduced into the housing through the intake port, out of the housing through the seat inlet, and a thermoelectric element disposed between the intake port and the seat inlet and heat-controlling the air introduced into the housing through the intake port. | 03-17-2011 |
| 20110061401 | HEATING AND COOLING SYSTEM FOR VEHICLE SEAT - A heating and cooling apparatus for a vehicle seat, may include a blower blowing air into a duct leading to the vehicle seat, and a thermoelectric element assembly connected to the duct and including a thermoelectric element that heats or cools air introduced toward the vehicle seat from the duct, the thermoelectric element having condensed water passages penetrating from one side to the other side thereof to allow condensed water to flow therethrough. | 03-17-2011 |
| 20110061402 | HEATING AND COOLING SYSTEM FOR VEHICLE SEAT - A heating and cooling system for a vehicle seat, may include a housing having an air supply port through which air communicates with the vehicle seat and an air exhaust hole through which air communicates with the outside of the housing, a thermoelectric element located in the housing between the air supply port and the air exhaust hole to selectively heat or cool air, which is directed toward the air supply port or the air exhaust hole, and a first blower fan provided in the air supply port to communicate air between the vehicle seat and the thermoelectric element. | 03-17-2011 |
| 20110061403 | HEATING AND COOLING SYSTEM FOR VEHICLE SEAT - A heating and cooling system for a vehicle seat, may include a heat exchanger cooling or heating air before the air is introduced into the seat, and a blower blowing air toward the heat exchanger, wherein the heat exchanger includes a positive temperature coefficient element assembly provided inside a housing of the heat exchanger to heat the air supplied from the blower, and wherein the positive temperature coefficient element assembly operates in a case of heating the seat but does not operate in a case of cooling the seat. | 03-17-2011 |
| 20110109127 | VEHICLE SEAT FOR COOLING AND HEATING - A vehicle seat for cooling and heating may include a seat pad, a mesh sheet having a certain thickness, a first film, and a porous seat cover, which are arranged sequentially in the direction in which air is introduced to flow. The seat pad has a pad hole, which allows air to pass through, and includes one or both of a seat cushion pad, which supports the buttocks of a user, and a seatback pad, which supports the upper body of the user. The mesh sheet has a porous network structure, through which air easily passes. The first film has a first film hole, which allows air to pass through. Air passages are maintained stable to maximize blowing performance, seating comfort is improved, and a ventilation structure is simplified to reduce manufacturing costs while improving productivity. | 05-12-2011 |
