FIELD: power industry.
SUBSTANCE: invention relates to heat engineering and can be used in heat exchangers with heat tubes. A heat exchanger with heat tubes for transfer of heat from hot gas to cold gas includes a housing with the first chamber for supply of hot gas through it, the second chamber for supply of cold gas through it and multiple heat tubes spreading between the first chamber and the second chamber. Partition panels are located in the chambers to divide the chambers into compartments with heat tubes; with that, partition panels are located in a plane that is generally parallel to a gas flow through the chambers; with that, direction of the gas flow through one compartment with heat tubes is parallel to gas direction through an adjacent compartment with heat tubes. Heat tubes are assembled into one or more cartridges located so that they can be removed from the corresponding compartments. Each cartridge with heat tubes includes a frame with a support panel, which, when the cartridge is being installed into the compartment, interacts with a partition wall between the first chamber and the second chamber so that gas-tight separation can be formed between the first and the second chambers. Heat tubes cross the support panel and are attached to it in a gas-tight way.
EFFECT: enlarging acoustic characteristics of a heat exchanger due to reduction of vibration induced with flows.
