Abstract

A double heat exchanger has a condenser having a condenser tank and a condenser tank cap for closing an open end of the condenser tank, and a radiator having a radiator tank and a radiator tank cap for closing an open end of the radiator tank. The condenser tank cap has a protrusion which protrudes toward the radiator tank and contacts the radiator tank to form a gap between the condenser tank and the radiator tank. The protrusion is also used to clamp the condenser tank cap to the condenser tank. As a result, the gap is securely formed between the condenser tank and the radiator tank, while heat is transferred from the radiator tank to the condenser tank only through the protrusion. Therefore, heat transfer from the radiator tank to the condenser tank is sufficiently restricted without increasing a manufacturing cost.
