A heat exchanger for an internal combustion engine may include a base tube and a flange extending at least partially around the base tube. The flange may be formed as a forged piece.

A metal heat transfer plate and heat pipe mounting structure includes a metal heat transfer plate and heat pipes embedded in the metal heat transfer plate in a flush manner. The metal heat transfer plate and heat pipe mounting method includes the steps of punching mounting slots in a metal heat transfer plate, processing each mounting slot into a respective flanged hole, reversely stamping each flanged hole to form top and bottom protruding flanges around each mounting slot, stamping each bottom protruding flange to create an insertion chamber, and press-fitting a flat heat pipe into each mounting slot and then stamping each top protruding flange into a respective deformed top protruding flange to wrap about one respective heat pipe and to keep each deformed top protruding flange flush with the top surface of the metal heat transfer plate and each heat pipe.

A heat exchanger which may be continuously mass-produced by press-fitting heat exchange fins into refrigerant tubes and a manufacturing method thereof. The manufacturing method includes processing a metal sheet into a plurality of rows of heat exchange fins, transferring the plurality of rows of heat exchange fins through a transfer apparatus, dividing the plurality of rows of heat exchange fins into heat exchange fins in odd-numbered rows and heat exchange fins in even-numbered rows and integrating the heat exchange fins in odd-numbered rows and even-numbered rows through integration apparatuses, vertically standing and aligning the heat exchange fins in odd-numbered rows and even-numbered rows, separating the heat exchange fins in odd-numbered rows and even-numbered rows into a number of heat exchange fins, which may be simultaneously press-fitted into refrigerant tubes, through separation apparatuses, and press-fitting the separated heat exchange fins into the refrigerant tubes.

A stacked disk cooler includes a plurality of heat exchanger plates arranged in a stacked configuration. The stacked disk cooler also includes a base trough arranged at an end of the stack and a connecting plate attached to the base trough. The connecting plate is a one-piece metal plate with a recess configured to accommodate the base trough.

A water-cooling heat dissipation device (1) includes a lower shell (10), a water-cooling plate set (20), an upper shell (30), and a water pump set (40) located in the upper shell (30). The lower shell (10) includes a heat exchange space (11), a water collection space (12), and a connecting port (13). The lower shell (10) includes a connecting opening (14), and the connecting opening (14) is provided with first threads (15). The upper shell (30) includes an external installation space (31) and an internal installation space (32). The upper shell (30) is provided with second threads (15). The upper shell (30) is combined with the lower shell (10) through the second threads (15) engaging with the first threads (15).
