Abstract

A composite heater apparatus for vehicles uses integrated tube which is partitioned from a coolant heater core tube part, in which coolant circulates, and an oil cooler tube part, in which engine oil circulates, and includes heat exchanging fin which is in contact with both the coolant heater core tube part and the oil cooler tube part to perform a heat exchanging process. Each header, which is coupled to each of opposite ends of the core tube, is partitioned from coolant circulation space and oil circulation space, via a partition walls. The partition wall includes a surface enlarging member to increase heat exchanging performance using heat conduction. When a vehicle is started in winter, in the initial operation stage of an engine, the vehicle is quickly heated, using the heat of engine oil which is heated prior to engine coolant.

Description

technical field [0001] The present invention relates generally to a compound heater device for a vehicle, and more particularly, to a heating device for a vehicle, which is intended to use the heat of the engine oil heated before the engine coolant, and the engine cools after the vehicle is started The fluid heats the vehicle's cabin until the fluid reaches a predetermined temperature. Background technique [0002] Generally, a heating device is installed in a vehicle to heat a cabin of the vehicle. The heating unit operates as described below. That is, while the heated refrigerant fluid of the engine circulates in the air conditioning box through the heater core, air outside or inside the vehicle passes through the heater core. During this process, the heat of the heated coolant flowing in the heater core is transferred to the air. This hot air is directed into the vehicle, thereby heating the vehicle's cabin. [0003] However, a problem with conventional heater cores f...
