The invention relates to a charge air cooler (5) for fuel engine comprising: a casing having an inlet (16) and an outlet (20), a heat exchanger (10) within the casing between the inlet (16) and the outlet (20), a thermally responsive draining mechanism (50, 60) for draining condensates, the draining mechanism (50, 60) being configured to drain condensates when temperature within the charge air cooler (5) is below a defined temperature, draining mechanism comprising a drain port (58, 68), a valve (51, 61, 52, 62, 53, 63) arranged on the drain port (58, 68), an actuation device (53, 63, 64) for moving the valve between an opened state and a closed state,
wherein the actuation device includes a phase change material.

A liquid-cooled heat dissipation device is disclosed, comprising a main body, a centrifugal pump, an inlet pipe, an outlet pipe, a centrifugal fan and a motor. The main body comprises a shaft hole, liquid flow channels and airflow channels. The centrifugal pump guides a cooling liquid through the inlet pipe, main body and outlet pipe. The centrifugal fan guides air into the main body axially from the shaft hole. After passing through the centrifugal fan, the air forms centrifugal airflows and leaves the body radially through the airflow channels. With an extended flow path of the cooling liquid and the radial flow of the centrifugal airflow provided by the present invention, the temperature of the cooling liquid may be quickly reduced and the cooling effect may be improved. Thus, the structure is compact, small, light-weight, easy-to-assemble.

A heat exchanger may include a collector and a connecting pipe. The collector may include at least one insertion opening. The connecting pipe may be inserted in the at least one insertion opening. The connecting pipe may include at least one bulge projecting radially to the outside. The at least one bulge may form a stop of the connecting pipe in an insertion direction in the at least one insertion opening. The at least one bulge may indicate a predefined angle-of-rotation position of the connecting pipe in the at least one insertion opening.

Heat exchanger fins and heat exchangers are disclosed. The heat exchanger fins disclosed herein comprise louvers and winglet-type vortex generators arranged to improve heat transfer efficiency.

The present disclosure provides a heat exchanger flat tube and a heat exchanger with the heat exchanger flat tube, the heat exchanger flat tube includes two plates opposite to each other, a fluid passage is formed between the two plates, a turbulence structure is provided in the fluid passage and has a gradually expanding portion and a gradually narrowing portion, both an extension direction of the gradually expanding portion and an extension direction of the gradually narrowing portion are consistent with a flow direction of a fluid, and the gradually narrowing portion is located downstream of the gradually expanding portion along the flow direction of the fluid.

A large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.
