ABSTRACT:
Disclosed is a heat exchange apparatus. The heat exchange apparatus comprises a first valve member rotating about a first rotational axis, a second valve member rotating about a second rotational axis, and a heat exchanging medium that is positioned on a gas stream path formed between the first valve member and the second valve member, has a channel for enabling gas to pass therethrough, and receives and stores thermal energy from passing hot gas and then transfers the stored thermal energy to passing cold gas. A flow direction of the gas passing through the heat exchanging medium is repeatedly changed as the first and second valve members rotate. The heat exchange apparatus has first and second guides connected respectively to both sides of the heat exchanging medium and has passages for guiding the gas passing through the heat exchanging medium.
