Embodiment Construction

[0009] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0010] see figure 1 , 2. The present invention includes a radiator body 1 and an upper cover 9. A cavity 2 is cut inside the radiator body 1, and a criss-cross columnar fin array 3 is evenly distributed in the cavity 2. The fin array 3 is connected with the heat dissipation The radiator body 1 is an integrated design. There is a channel 4 with a rectangular cross section on the outside of the cavity 2. An O-shaped sealing ring is placed in the channel 4. The two ends of the radiator body 1 are provided with water inlet and outlet pipes 5 connected to the cavity 2. 6. The water inlet and outlet pipes 5 and 6 are integrated with the radiator body 1. There are countersunk screw holes 8 at the four corners of the radiator body 1, and countersunk holes 10 are opened at the four corners of the upper cover 9. The rad...

Abstract

It is a water cooling type CPU heat dissipater. It contains heat dissipater body with admitting pipe and exhaust pipe on two stage, a cavity joined with admitting pipe and exhaust pipe inside the heat dissipater body and crossbar interfluent feather array in the cavity. This invention uses distilled water as water cooling type heat dissipater of cooling working substance and quickly transmits CPU's heat to condenser and into the air by this water cooling type heat dissipater; in the mean time, on one hand, crossbar interfluent feather array increases area of dissipation and on the other hand, when water flows through columnar feather array, the columnar feather array has turbulent effect, increases heat emission effect and makes water flows even in the cavity. In this way, great stress raised by great temperature gradient on the CPU's surface can be avoided and CPU's physical damage can also be avoided.

Description

technical field [0001] The invention relates to a computer CPU radiator, in particular to a water-cooled CPU radiator. technical background [0002] The computer's central processing unit, referred to as CPU, is one of the most important parts for the normal operation of the computer. The quality of its heat dissipation is directly related to the life of the computer and the quality of computing. Because the CPU tends to generate high heat during operation, the commonly used heat sink is mainly a metal heat sink body. This metal heat sink is mostly made of aluminum. At present, more and more copper materials are used. Casting) is provided with several grooves and rectangular parallelepiped fins, so as to have a better heat dissipation surface area; then, the fan above the fins blows and dissipates heat against the heat dissipation fins. However, with the rapid development of computer equipment and the competition between CPU chip giants Intel and AMD, the CPU as the core of...
