Abstract
The utility model discloses a high-efficiency projector heat pipe heat radiation system which is provided with a heat pipe, a pedestal which fixes the heat pipe and enables the heat pipe to fully contact with a heat source, and heat radiation fins. The high-efficiency projector heat pipe heat radiation system is characterized in that the pedestal is arranged in the middle of the heat pipe, and the heat radiating fins are arranged on the two ends of the heat pipe. Compared with the prior art, the maximum heat radiation capability limit of the heat pipe heat radiation system is improved, and the space utilization rate of the system is improved. The capability of the heat pipe heat radiation system is one to two times the capability of a conventional system, and the lengths of the two ends can be determined reasonably and flexibly according to the demand of the system arrangement.
Description
Technical field
The utility model belongs to heater element heat dissipation technology field, is specifically related to a kind of heat pipe radiating system that is applied to the solid state light emitter heat radiation of projector.
Background technology
Heat pipe is a kind of heat conduction technology of high-level efficiency high reliability, in projector, is usually used in the heat radiation of big heat high heat flux heat-generating units.The basic structure of heat pipe is made up of evaporator section, adiabatic section and condensation segment three parts.This cooling system is made up of pedestal, heat pipe and radiating fin three parts.The effect of pedestal mainly is that the evaporator section of heat pipe is closely contacted with thermal source, and certain fixation is arranged simultaneously; Thereby fin is to improve heat-exchange capacity in order to increase cooling system with extraneous heat exchange area.In practical application, the maximal heat transfer ability of general heat pipe receives stickiness limit, boiling limit, capillary limit, velocity of sound limit and carries the restriction of limit etc., often is difficult to give play to maximum capacity and efficient.Improving the maximal heat transfer ability and the efficient of conventional heat pipe, is the constantly problems of research of prior art personnel.
The utility model content
For solving the above-mentioned defective that prior art exists, the purpose of the utility model is to provide a kind of maximal heat transfer capacity limit that improves the adopting heat pipes for heat transfer system, improves the efficient projector heat pipe cooling system of the space availability ratio of system.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts: this efficient projector heat pipe cooling system; Have heat pipe, fixing heat pipe and make heat pipe and abundant substrate contacted of thermal source and radiating fin; It is characterized in that: said pedestal is positioned at the middle part of heat pipe, and said radiating fin is located at the two ends of heat pipe.
Said heat pipe is two, and these two heat pipes are " U " shape to launch at two ends.
Said heat pipe is one, and this heat pipe is " U " shape.
Adopt the beneficial effect of technique scheme: this efficient projector heat pipe cooling system has two adiabatic sections and condensation segment; Be that evaporator section (thermal source) is in the centre; Heat pipe extends to two ends; Form two adiabatic sections and condensation segment, like this in the maximal heat transfer ability that just can improve heat pipe under similar circumstances.Under the radiating fin of same heat pipe, as much, same thermal source and same hot test environment; The ability of this heat pipe radiating system is 1 to 2 times of legacy system heat-transfer capability; Simultaneously can make full use of system space, and reasonably confirm the length at two ends flexibly according to the needs of system layout.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the basic structure synoptic diagram of the utility model.
Fig. 2 is the cooling system structural representation with two heat pipes.
The cooling system structural representation that Fig. 3 takes the shape of the letter U for heat pipe.
Embodiment
Efficient projector heat pipe cooling system as shown in Figure 1 has heat pipe 3, fixing heat pipe and make heat pipe and abundant substrate contacted 2 of thermal source and radiating fin 1, and said pedestal 2 is positioned at the middle part of heat pipe 3, and said radiating fin 1 is welded on the two ends of heat pipe 3.Cooling system with two heat pipe structures as shown in Figure 2; Constitute by heat pipe 3,4, pedestal 2 and radiating fin 1,5; These two heat pipes are " U " shape to launch at two ends, makes full use of system space, and radiating fin 1,5 is welded on the two ends of heat pipe 3,4 respectively simultaneously.Heat pipe radiating system as shown in Figure 3, said heat pipe 3 is one, and these heat pipe 3 global shapes are " U " shape, and pedestal 2 is positioned at the middle part of heat pipe, and radiating fin 1 is welded on the two ends of heat pipe 3 simultaneously, has practiced thrift the space.
