Benefits of technology

The present invention is designed to improve the cooling performance of a radiator in a vehicle by optimizing the positions of the cooling water inlet and outlet and adding a separate filler neck to increase the flow rate. The technical effect is better cooling performance achieved through these innovative measures.

Problems solved by technology

However, the related art radiator has a problem in that, if the cooling water discharged after cooling the engine has bubbles dissolved therein, making the cooling water to flow in a state the cooling water contains the bubbles which have a low heat transfer coefficient, the bubbles occupy a certain volume in a cooling water circulation passage, and make a heat exchange performance of the cooling water poor to reduce cooling efficiency.
Moreover, since the reduced cooling efficiency of the radiator may lead to supply the cooling water to the engine in a state the cooling water is failed to be cooled to a required temperature, making the cooling water to fail to cool down the engine properly, an overall cooling performance of the vehicle may become poor.

Abstract

A radiator in a vehicle may include an inlet header tank for introduction of cooling water, an outlet header tank for discharging the cooling water, a heat exchanger unit having a plurality of tubes connected between opposite insides of the inlet header tank and the outlet header tank and heat dissipation fins for enhancing heat exchange between the cooling water flowing through the tubes and external air, an inlet and an outlet respectively formed substantially at centers of one side of the inlet header tank and one side of the outlet header tank in a height direct, and a filler neck connected to an engine and connected to the inlet by a main hose for introducing the cooling water from the engine to the inlet, and connected to one of the inlet header tank and the outlet header tank by a sub-hose which is separate from the main hose.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority of Korean Patent Application Number 10-2014-0072419 filed on Jun. 13, 2014, the entire contents of which application are incorporated herein for all purposes by this reference.BACKGROUND OF INVENTION[0002]1. Field of Invention[0003]The present invention relates to a radiator in a vehicle. More particularly, the present invention relates to a radiator in a vehicle, in which positions of an inlet and an outlet of cooling water to / from an engine are optimized to reduce flow resistance and increase a flow rate thereof for improving a cooling performance.[0004]2. Description of Related Art[0005]In general, a vehicle runs as an combustion of mixed gas of fuel and air in an engine cylinder compressed by a piston is transmitted to driving wheels. An engine which obtains driving force from the combustion is provided with a cooling unit, such as a water jacket, for cooling down heat of the combustion, and a ra...
