Abstract:
A method for manufacturing a two-phase heat exchange device is provided. The method includes the steps of providing a container having an opening and a first wick structure disposed on the inner surface thereof, adding a predetermined material into the container, providing an cover and joining the cover with the container to construct a main body of the two-phase heat exchange device, wherein the cover seals the opening to form a closed space within the main body, and forming a second wick structure on the inner surface of the cover, wherein the first and second wick structures form a continuous structure covering the entire inner surface of the main body.
Abstract:
A heat dissipation module includes a plurality of fins and a heat pipe connected with the fins. The heat pipe includes a body, which forms an enclosed space, and an inner ring. A wick structure is disposed on the inner surface of the body, and the inner ring is disposed in the enclosed space for increasing a structural strength of the heat pipe. The inner ring is pressed against the top and bottom of the body or in contact with the wick structure located at the top and the bottom of the body, respectively. The inner ring includes at least one opening located close to the top of the body for communicating inside and outside of the inner ring.

The two-phase heat exchange device includes a main body and a continuous wick structure. The main body forms a closed space therein, and the continuous wick structure is disposed on the entire inner surface of the main body. Methods for manufacturing a two-phase heat exchange device and a heat dissipation apparatus are also introduced.
Abstract:
A heat dissipation module includes a heat column and a plurality of heat dissipation fins disposed outside of the heat column and connected with the heat column. The heat column has a column body and a base, and the column body has a top portion and a sidewall ringed with the top portion. The sidewall and the top portion are integrally formed. The base is disposed opposite to the top portion, and the base has an indentation for allowing an end of the sidewall of the column body to insert so as to form a closed space between the base and the column body. The base further has an annular protrusion close to the indentation, and after the end of the sidewall of the column body is inserted into the indentation of the base, the annular protrusion is processed to be filled between the indentation and the sidewall so as to tightly assemble the base and the column body.
Abstract:
A heat dissipation module includes a heat pipe and at least one fin, which is connected to and disposed on an external surface of the heat pipe. The heat pipe includes a casing, a wick and a working fluid. The casing has an accommodating space and a bottom portion. The bottom portion has an uneven surface facing the accommodating space. The wick is disposed over the uneven surface of the bottom portion and the working fluid is filled within the casing.
Abstract:
A heat-dissipating device. The heat-dissipating device includes a base, a plurality of heat-dissipating fins, and a fan. The heat-dissipating fins are disposed around the base. The base includes a first end surface and a second end surface. The first end surface contacts a heat source. The fan is disposed on the second end surface. An airflow space is formed between the heat-dissipating fins and the first end surface for airflow to pass through.
Abstract:
A heat dissipation module includes a first annular wall, a second annular wall, at least one porous structure, at least one first heat conductive structure and second heat conductive structure. The second annular wall with respect to the first annular wall, and the first annular wall and the second annular wall are jointed to form a closed chamber. The porous structure is disposed on an inner surface of the closed chamber. The first heat conductive structure is externally connected to the first annular wall and the second heat conductive structure is internally connected to the second annular wall.

Abstract:
A heat dissipating module includes a heat dissipating apparatus and a fan. The fan is disposed adjacent to a side of the heat dissipating apparatus. A heat dissipating apparatus includes a flat heat column and a plurality of heat dissipating fins. The heat dissipating fins are disposed at the exterior of the flat heat column. A flat heat column has a pipe-body and a base, and the pipe-body includes a circular sidewall, an open end and a closed end. The base is coupled to the circular sidewall at the open end to form a closed space in the flat heat column, wherein the circular sidewall converges from the open end toward the closed end to form a converging part and a flat part.
