Heat plate type cooler module
View Patent ↗A heat plate type cooler module includes a heat plate, which is formed of a bottom cover plate and a top cover plate and having a working fluid filled in a vacuum chamber between the top cover plate and the bottom cover plate; heat pipes each having a cold end and a top end; a locating plate covered on the heat plate to hold the hot end of each heat pipe in contact with the heat plate; and radiation fins fastened to the cold ends of the heat pipe by press-fitting.
1. A cooler module comprising a heat plate, at least one heat pipe, and a locating plate fastened to said heat plate to affix said at least one heat pipe to said heat plate, wherein:
said heat plate comprises a bottom cover plate, a top cover plate sealed to said bottom cover plate, a vacuum chamber defined between said bottom cover plate and said top cover plate, and a working fluid filled in said vacuum chamber; and
said locating plate is covered on said heat plate and comprises at least two transversely extending bottom locating grooves and a springy middle protruding portion separating the transversely extending bottom locating grooves into two groups, wherein each of the transversely extending bottom locating grooves accommodates a subset of said at least one heat pipe to hold one hot interface of each said heat pipe in contact with said heat plate,
and a fastener attached to the springy middle protruding portion of the locating plate for fastening the heat plate to a heat source.
2. The cooler module as claimed in claim 1 , wherein said at least one heat pipe is mounted with a plurality of radiation fins, each said heat pipe having at least one cold interface respectively press-fitted into said radiation fins.
3. The cooler module as claimed in claim 1 , wherein said top cover plate of said heat plate has a dimension greater than said bottom cover plate of said heat plate, and said top cover plate has a plurality of mounting through holes cut through top and bottom sides thereof outside said bottom cover plate.
4. The cooler module as claimed in claim 1 , wherein said locating plate has a plurality of mounting through holes respectively fastened to respective mounting through holes of said top cover plate.
5. The cooler module as claimed in claim 1 , wherein the hot interface of each said heat pipe has a flat configuration.
6. The cooler module as claimed in claim 1 , wherein each said heat pipe has two horizontal end sections pointing in a substantially same direction, one of which terminating in the respective hot interface.
7. The cooler module as claimed in claim 6 , wherein said at least one heat pipe includes a plurality of heat pipes arranged in two sets and bonded to said heat plate.
8. The cooler module as claimed in claim 2 , wherein said radiation fins are arranged into a radiation fin module and mounted with an electric fan.
9. The cooler module as claimed in claim 1 , wherein said at least one heat pipe includes a plurality of U-shaped heat pipes, each having two opposite ends respectively terminating in a respective cold interface.
10. The cooler module as claimed in claim 9 , wherein the cold interfaces of said U-shaped heat pipes are mounted with a radiation fin module formed of a plurality of radiation fins, the cold interfaces of said U-shaped heat pipes being tightly inserted through said radiation fins.
11. The cooler module as claimed in claim 1 , wherein each transversely extending bottom locating groove accommodates at least two of the heat pipes.
