Problems solved by technology

[0004] Since the small heat pipes are welded together with the substrate, the heat generated by the electronic components is firstly transferred to the substrate, and then the heat is transferred from the substrate to the heat pipe, which increases the thermal resistance, and the processing difficulty of installing heat sinks on multiple small heat pipes increases, the cost is high, and the impact The large-scale application of this heat pipe radiator

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, this cylindrical heat pipe includes an exhaust pipe 1, a top cover 2, a capillary cover plate 3, a capillary structure sintered layer 4, a pipe body 5, and a bottom plate 6. The cylindrical heat pipe consists of an exhaust pipe 1, a top cover 2, a pipe body 5, and a bottom plate 6 to form a sealed cavity, and the inside is in a vacuum state; the lower end of the pipe body 5 is provided with a bottom plate 6, which is integrally formed with the pipe body 5. Or the two parts are welded together, the outer diameter of the bottom plate 6 and the pipe body 5 is the same, or the bottom plate 6 is larger than the outer diameter of the pipe body 5, and its shape is circular, or square, or triangular, or rhombus, or other irregular shape. The upper end of the pipe body 5 is provided with a step 5-1, and a capillary cover p...

Abstract

The columnar heat pipe has sealed vacuum cavity comprising gas exhaust pipe, top cover, tube and bottom board; and has bottom board below the tube, step in the upper end of the tube, capillary cover mounted in the step, top cover on the capillary cover, sealed gas exhaust pipe on the top cover, sintered porous capillary layer in the inner wall of the tube and the inner surface of the bottom board to form work liquid circulating passage together with the capillary cover and work liquid adsorbed to the sintered layer and the capillary cover. The present invention has the beneficial effects caused by the phase change heat transfer of the evaporation and condesation of work fluid inside the columnar heat pipe, including fast heat transfer rate, great heat transfer capacity, homogeneous temperature, high stability, etc.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a cylindrical heat pipe used for heating the end faces of heating electronic components (including a personal computer CPU). Background technique [0002] With the development and miniaturization of electronic products such as computers, communications, and photoelectric lighting LEDs at an astonishing rate in the "Moore's Law" equivalent series, the relative heat treatment problems are also increasing, and the heat flux is also increasing. How to solve this heat dissipation problem in a limited space and ensure the normal operation of electronic products requires that cooling module manufacturers and related scientific research institutions around the world increase investment in scientific research, actively seek and develop new types of high-efficiency heat dissipation that can meet the development needs of next-generation electronic products components. [0003] A heat pipe is a small amount o...
