An exchangeable filter of a treatment device has a housing with a housing pot and a housing cover connected to the open side of the housing pot. The exchangeable filter is connectable to a connecting head of the treatment device with a bayonet-type connecting device. The connecting device has a housing connecting part on the housing interacting with a head connecting part of the connecting head for connecting the connecting device. The housing has an inlet for a fluid to be treated connectable to a supply conduit of the treatment head and an outlet for the treated fluid connectable to a discharge conduit of the treatment head. The housing pot has a rim at the open side of the housing pot. The rim radially outwardly surrounds the housing connecting part and axially projects past the housing connecting part in a direction away from the housing bottom.

The present disclosure relates to a heat radiator and a turbo fracturing unit comprising the same. The heat radiator includes: a cabin; a heat radiation core disposed at the inlet and configured to allow a gas to pass therethrough; a gas guide device disposed at the outlet and configured to suction the air within the cabin to the outlet; and noise reduction core disposed within the cabin, which is of a structure progressively converging to the outlet. The heat radiator is configured to enable the gas to enter the cabin via the inlet, then sequentially pass through the heat radiation core, a surface of the noise reduction core and the gas guide device, and finally be discharged out of the cabin. The heat radiator according to the present disclosure is a suction-type heat radiator which can regulate the speed of the gas guide device based on the temperature of the gas at the inlet, thereby avoiding energy waste and unnecessary noise. The smooth curved surface of the noise reduction core can reduce noise without affecting the gas flow.
