Description

Cooler Module {COOLER MODULE}

The present invention relates to a cooler module for cooling an electronic chip. More specifically, the horizontal cooler module, the cooler module has a flat wall portion of the heat pipe that is exposed to the outside of the base block to be in direct contact with the heat source for rapid heat dissipation of the heat energy from the heat source to fit It is composed of joined members.

Heat pipes are widely used in cooler modules for cooling semiconductor chips and the like. In addition to the heat pipes, conventional cooler modules include a heat sink and a base block formed of a plurality of heat sink fins. The heat dissipation fin is made by extrusion molding of aluminum or copper. The heat tubes are sealed metal tubes filled with a working fluid. The base block is a block of aluminum or copper. Since the heat tubes and the base block of this type of cooler module are made of different materials, nickel plating technology is required to connect the heat tubes and the base block by tin-lead alloy soldering or thermal bonding. The manufacturing and assembly process of such cooler module is complicated, resulting in low production rate and high manufacturing cost. Soldering between the base block and the heat pipes reduces the heat transfer efficiency of the cooler module relatively. In addition, environmental pollution can occur during the soldering of the heat pipes to the base block.

In use, the base block (aluminum base block or copper base block) absorbs the heat energy from the electronic chip, transfers the absorbed heat energy to the heat pipe, and then transfers it to the heat sink for additional heat dissipation. It is placed in contact with the face. Since heat energy is indirectly transferred to the heat pipe and heat sink, the heat dissipation efficiency of this type of cooler module is low.

In order to solve the above problems, the heat sink, heat pipe, and base block are combined by fitting, not by soldering or thermal bonding, to simplify the assembly process and reduce environmental pollution. Direct contact with the heat source is to enhance the heat transfer efficiency and heat dissipation effect.

According to one aspect of the invention, the horizontal cooler module includes a plurality of heat sink fins, a plurality of heat pipes, and the base block. The constituent members of the cooler module have a perfect structure. Each of the heat tubes has a flat wall portion exposed to the outside of the base block for direct contact with the electronic chip to transfer heat energy directly from the electronic chip to the heat sink for rapid heat dissipation.

According to another aspect of the present invention, the coupling of the constituent members of the cooler module is increased by thermal expansion, thereby providing excellent thermal conductivity and excellent heat dissipation. Since the horizontal cooler module does not require tin-lead alloy soldering or nickel plating, the manufacturing method of the present invention does not cause any environmental pollution due to tin-lead alloy soldering or nickel plating. Therefore, the manufacturing method of the present invention is well suited to environmental protection as compared to the manufacturing method of the conventional cooler module.

According to yet another aspect of the present invention, the base block includes a plurality of bottom opening grooves each receiving the heat pipe, and a plurality of clamping ribs protruding from the bottom wall and extending along both walls of the bottom opening grooves. rib). After the heat pipes are inserted into the bottom open grooves of the base block, the clam flanges may be fixed in such a way that the heat pipes are held in engagement with the bottom open grooves, and may be laterally pressed to tighten the heat pipes.

The present invention is a flat wall portion formed in the heat pipe can directly and heat transfer heat energy to the heat sink can be quickly and effectively, the heat expansion is more efficient because the coupling force of the component is possible, the efficient heat transfer, by fitting the coupling of the component It is effective in simplifying the assembly process, lowering production costs, and reducing environmental pollution since there is no process such as soldering.

1 to 5, the horizontal cooler module of the present invention is shown to include a plurality of heat dissipation fins 1, a plurality of heat pipes 2, and a base block 3.

The heat dissipation fins 1 are stacked to form a heat sink 10.

The heat tube 2 is an I-type or U-type closed tube filled with a working fluid, each heat tube having a first extension branch 21 at one end and a second extension branch 22 at the other end. And a flat wall portion 23 formed on the bottom surface of the second extension branch 22 (see FIG. 6). The flat wall portion 23 of the heat pipe 2 is exposed toward the outside of the bottom surface of the base block 3 to form a plane having the same height as the bottom surface of the bottom wall of the base block 3.

The base block 3 is a block made of metal (copper or aluminum), and includes a top wall 31 fixed to the bottom surface of the heat sink 10 and a plurality of bottom opening grooves for accommodating the heat pipe 2 ( 32 and a plurality of clamping ribs extending in the longitudinal direction along both sides facing each other in each of the bottom opening grooves 32 so that the heat pipe 2 is fixed to the bottom opening groove 32. (clamping rib) 33, and includes a plurality of heat pipe fixing jaw 321 formed in the longitudinal direction in order to more firmly fix the second extension branch 22 in the bottom opening grooves (32). .

The heat dissipation fin 1, the heat pipe 2, and the base block 3 are tightly fitted to each other. Due to the thermal expansion of the heat pipe 2, the members of the horizontal cooler module of the present invention are firmly coupled to each other. After installing the horizontal cooler module, the flat wall portion 23 of the second extension branch 22 of the heat pipe 2 is exposed in a flat shape toward the outside of the base block 3 and is in contact with a heat source such as an electronic chip. It is disposed as close as possible to radiate heat quickly by transferring heat energy from the electronic chip to the heat sink 10. Since heat energy is directly transferred from the electronic chip to the heat sink 10 by the heat pipes 2 for rapid heat dissipation, the present invention has a very high heat dissipation efficiency.

Since the members of the cooler module of the present invention are firmly fitted to each other, they are firmly fixed without vibration between the members, and the production cost is reduced because the manufacture of the cooler module is easy and fast. Since the flat wall portion 23 of the heat pipe 2 directly contacts the heat supply source, the horizontal structure cooler module can efficiently dissipate heat, so the horizontal structure cooler module of the present invention provides excellent thermal conductivity and performs excellent heat dissipation. do. Furthermore, according to the present invention, since the necessity of soldering of the tin-lead alloy is eliminated, environmental pollution due to the soldering of the tin-lead alloy is not caused in the manufacture of the cooler module. That is, this invention is invention which meets more environmental protection.
