The cross flow heat exchanger is commonly used in applications such as heating, ventilating and air conditioning. It is also encountered as vehicle engine radiator.
This type of heat exchange occurs when the flow direction of the two fluids cross each other. In the HT35X, hot water flows in and out of a radiator, perpendicular to air stream, which is being pulled into the radiator by an axial fan.
The convection between the two fluids through fins surface on the radiator implements the heat exchange.
