A heat exchanger and related methods are provided. An example heat exchanger has moveable or flexible joints between tubular members that contain flowing heating medium. The moveable joints allow the overall structure of the heat exchanger to adapt to expansion, contraction, and other stresses of high-temperature, high thermal-gradient operation. The moveable joints also provide breaks in the structure, enabling repair or replacement of parts. A negative internal pressure is maintained to prevent flue gases and heat from escaping through the moveable joints, and prevents contamination of the ambient environment and products being dried. Moveable support measures also allow each tier of tubes to expand or contract independently of each other to accommodate thermal gradients within a given tier of tubes, within a given manifold, and between tiers of tubes, so that virtually all of the thermal stresses associated with conventional heat exchangers are mitigated or eliminated.

A heat exchange system for realizing an adequate heat exchange among a plural type of fluids uses a refrigerant radiator and a radiator which are combined to have one unit for enabling heat exchange between a refrigerant and a coolant, and decreases an inflow amount of the coolant flowing into the radiator when coolant temperature of the coolant flowing into the radiator is equal to or higher than a second standard temperature, which is set to be lower than a temperature of the refrigerant flowing into the refrigerant radiator, and is equal to or lower than a predetermined first standard temperature. In such manner, heat from the refrigerant is effectively transferred to an outside air by reducing an unwanted heat exchange between the refrigerant and the outside air.

The housing wall and the tube bottoms delimit a flow chamber for the coolant, The heat exchange tubes being arranged so as to form a tube bundle are formed with straight sections and deflection zones, wherein the heat exchange tubes in at least two deflection zones sweep an angle of at least 90°.
