Description

Combined radiating device

Technical field

The utility model relates to a kind of heat abstractor, relate in particular to a kind of being installed on central processing unit (CPU) or the heat generating component, utilize being fastened and connected between heat-conducting seat and radiator to increase the closeness of contact of each inter-module, improve the combined radiating device of thermal conduction effect.

Background technology

Central processing unit (CPU) speed of service that in the past was used in computer is slow, it is enough as the heat dissipation equipment of CPU to add the radiator that radiator fan constitutes with radiator, but the clock frequency of central processing unit has surpassed 3GHz recently, and the clock frequency of CPU and its caloric value are proportional, therefore, above-mentioned radiator is subjected to the restriction of enclosure space, more and more be difficult to effectively solve the problem of heat radiation with the raising of the central processing unit speed of service, therefore use the heat spreader structures of forming with heat pipe to dispel the heat, become another solution of heat radiation problem.

Fig. 1 is a known combination formula heat abstractor, as shown in Figure 1, mainly includes a heat-conducting seat 10a, two heat pipe 20a and a radiator 30a.Wherein heat-conducting seat 10a bottom surface is flattened on the surface of central processing unit (CPU), and its end face offers two groove 11a, and the groove 11a end of heating tube 20a respectively installs.The other end of heat pipe 11a is located on the radiator 30a.Radiator 30a is piled up by a plurality of radiating fin 31a and forms, and offers the perforation 32a of mutual correspondence on each radiating fin 31a, and heat pipe 11a inserts perforation 32a and is connected with each radiating fin 31a.Between the contact-making surface of each assembly, be coated with heat-conducting medium, thus, form a heat-pipe radiator.

Yet there is following defective in known heat-pipe combined heat abstractor:

1. because each heat pipe 20a is an elongated pipe body, the restriction that its inner capillary structure that can be provided with and working fluid are subjected to the space, and the contact area of itself and heat-conducting seat 10a and radiator 30a is narrow and small, thermal resistance is big, and therefore, the heat that heat pipe 20a can take away has its limitation.

2. the perforation 32a of radiating fin 31a is a circular hole, when being connected with heat pipe 20a, evenly applies at the difficult heat-conducting medium with viscose of the internal face of perforation 32a, makes heat pipe 20a and being connected of radiator 30a can't reach good contact effect.

3. because the runner of this heat-pipe radiator does not have streamlinedly, when radiator fan is blown into air-flow downwards, air-flow is produced between runner mutually clash into, thereby cause that flow resistance is big, eddy current is many, noise reaches bad phenomenon such as thermal convection coefficient of conductivity difference greatly.

The design people is in view of the defective that exists in the above-mentioned prior art, rely on the research and development experience for many years of being engaged in, at the inconvenience that can reconstruct and defective, through concentrating on studies and cooperating actual utilization, in line with excelsior spirit, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
