Abstract
A heat sink (1), has heat pipes (3) which are disposed in a high temperature section (A) of a base plate (2) on which a heating element (4) is disposed so that the heat pipes (3) extend from the high temperature section (A) to low temperature sections (B) in different directions.
Claims7
A heat sink, characterized in that heat pipes are disposed in a high temperature section of a base plate on which a heating element is disposed so that the heat pipes extend from the high temperature section to low temperature sections in different directions relative to the high temperature section;
- wherein the heat pipes extend radially from the high temperature section to the low temperature sections.
A heat sink, characterized in that heat pipes are disposed in a high temperature section of a base plate on which a heating element is disposed so that the heat pipes extend from the high temperature section to low temperature sections in different directions;
- wherein the heat pipes are disposed in proximity to each other in the high temperature section so as to be in parallel and/or overlap with each other.
A heat sink, characterized in that heat pipes are disposed in a high temperature section of a base plate on which a heating element is disposed so that the heat pipes extend from the high temperature section to low temperature sections in different directions;
- wherein the number of heat pipes disposed so as to extend from the high temperature section to the low temperature sections on a leeward side exceeds the number of heat pipes disposed so as to extend from the high temperature section to the low temperature sections on a windward side.
A heat sink, characterized in that heat pipes are disposed in a high temperature section of a base plate on which a heating element is disposed so that the heat pipes extend from the high temperature section to low temperature sections in different directions;
- wherein the base plate includes an extruded material having a plurality of holes, in which the heat pipes varied in lengths and positions for the respective holes are disposed.
A heat sink, characterized in that heat pipes are disposed in a high temperature section of a base plate on which a heating element is disposed so that the heat pipes extend from the high temperature section to low temperature sections in different directions;
- wherein the heat sink is used in railroad vehicles or automobiles.
