Temperature-uniforming plate with supporting effect

Abstract

A temperature-uniforming plate with supporting effect includes a base plate and a cover plate mounted onto the base plate, wherein a frame is sandwiched between the base plate and the cover plate to define a vacuum chamber among the base plate, the cover plate and the frame. The frame has two arms inwardly extending therefrom and extending to a heat conducting area formed on the base plate. A passage is defined between the two arms. The two arms are clamped between a top surface of the base plane and a bottom surface of the cover plate. The temperature-uniforming plate has a thinning and simplified structure for easily formed, reducing manufacturing cost and providing a supporting effect.

We claim: 
     
         1 . A temperature-uniforming plate comprising:
 a base plate formed with a heat conducting surface and a inside surface, wherein a contacting area is formed on the heat conducting surface and adapted to be abutted a heat source;   a cover plate mounted onto the base plate, the cover plate formed with a top surface and a bottom surface;   a frame sandwiched between the inside surface of the base plate and the bottom surface of the cover plate;   a vacuum chamber defined among the inside surface of the base plate, the bottom surface of the cover plate and an interior of the frame, wherein the vacuum chamber is provided for containing coolant; at least one capillary structure and at least one supporting structure disposed in the vacuum chamber, wherein the at least one supporting structure has two opposite ends respectively abutting against the inside surface of the base plate and the bottom surface of the cover plate;   two arms respectively extending from the interior of the frame and corresponding to each other, wherein each arm has a distal end separated from each other, the two arms sandwiched between the inside surface of the base plate and the bottom surface of the cover plate; and   a passage defined between the two distal ends of the two arms, the distal end of each of the two arms situated within the contacting area.   
     
     
         2 . The temperature-uniforming plate as claimed in  claim 1 , wherein each arm has a branch laterally extending therefrom and the distal end is formed on a free end of the branch of each of the two arms. 
     
     
         3 . The temperature-uniforming plate as claimed in  claim 2 , wherein the two distal ends corresponds to each other. 
     
     
         4 . The temperature-uniforming plate as claimed in  claim 3 , wherein the branch of each of the two arms has a deputy passage defined in a top thereof. 
     
     
         5 . The temperature-uniforming plate as claimed in  claim 4 , wherein each arm has an assembling hole, the base plate has two assembling holes defined therein and the cover plate has two assembling holes defined therein, and wherein the assembling hole in each of the two arms aligns with a corresponding one of the two assembling holes in the base plate and the cover plate. 
     
     
         6 . The temperature-uniforming plate as claimed in  claim 5 , wherein the base plate has a sidewall peripherally extending therefrom and the cover plate has a sidewall wall peripherally extending therefrom, and wherein the two sidewalls abutted each other after being assembled. 
     
     
         7 . The temperature-uniforming plate as claimed in  claim 3 , wherein the frame has a slot defined therein, the slot provided for making a vacuum status in the vacuum chamber and filling the coolant into the vacuum chamber, wherein the slot is closed by filler after filling the coolant into the vacuum chamber. 
     
     
         8 . The temperature-uniforming plate as claimed in  claim 4 , wherein the frame has a slot defined therein, the slot provided for making a vacuum status in the vacuum chamber and filling the coolant into the vacuum chamber, wherein the slot is closed by filler after filling the coolant into the vacuum chamber. 
     
     
         9 . The temperature-uniforming plate as claimed in  claim 3 , wherein the frame has a through hole laterally defined therein, the through hole provided for making a vacuum status in the vacuum chamber and filling coolant into the vacuum chamber, wherein the through hole is closed by filler after filling the coolant into the vacuum chamber. 
     
     
         10 . The temperature-uniforming plate as claimed in  claim 4 , wherein the frame has a through hole laterally defined therein, the through hole provided for making a vacuum status in the vacuum chamber and filling coolant into the vacuum chamber, wherein the through hole is closed by filler after filling the coolant into the vacuum chamber. 
     
     
         11 . The temperature-uniforming plate as claimed in  claim 3 , wherein the cover plate is formed with a raised portion such that a gap is defined between the cover plate and the frame, the gap provided for making a vacuum status in the vacuum chamber and filling coolant into the vacuum chamber, wherein the gap is closed by filler after filling the coolant into the vacuum chamber. 
     
     
         12 . The temperature-uniforming plate as claimed in  claim 4 , wherein the cover plate is formed with a raised portion such that a gap is defined between the cover plate and the frame, the gap provided for making a vacuum status in the vacuum chamber and filling coolant into the vacuum chamber, wherein the gap is closed by filler after filling the coolant into the vacuum chamber.
