Abstract

A computer PCD radiator is composed of a base which is a sealed cavity, thermal isolating plate for dividing said cavity into high and low pressure chambers, condenser on the base, whose inlet is connected to high pressure chamber via connector, one-way outlet valve in said connector, air returning pipe connected to outlet of condense and extended to the bottom of low pressure chamber, check valve at outlet of said air returning pipe, and thermal isoalting slot on base. Its advantages are compact structure, low heat resistance, high effect and low cost.

Description

The computer PCD heating radiator

One, technical field

The present invention relates to a kind of heating radiator, particularly a kind of heating radiator that is used for the computer PCD heat radiation.

Two, background technology

The computer PCD operation time will be generated heat, and reliability and stability and the temperature of its work are closely related, and working temperature is high more, and reliability and stability are poor more, in the time of seriously even cause PCD to burn.In order to reduce the working temperature of computer PCD, guarantee the computer security operation, the general employing of computer PCD heat radiation at present heat sink adds fan electromotor and forms heat abstractor, by the fan forced heat radiation.But adopting the PCD one of fan heat radiation is that thermal resistance is big, and radiating effect is poor; The 2nd, produce neighbourhood noise; The 3rd, consumes energy; The 4th, be easy to generate fault.

Three, summary of the invention

For overcoming the disadvantage of above-mentioned existence, problem to be solved by this invention just provide a kind of simple and reasonable, working stability reliable, the computer PC B heating radiator of good heat dissipation effect, non-consumes energy.The technical scheme that the present invention overcomes the above problems employing comprises base, base is the sealed chamber of hollow, the thermal insulation board that is arranged in the base is separated into hyperbaric chamber and low-pressure chamber to chamber, condenser is arranged on the base, and the import of condenser links to each other with the hyperbaric chamber by Connection Block, is provided with unidirectional air outlet valve in Connection Block, the outlet of condenser links to each other with muffler, muffler reaches the bottom of low-pressure chamber, is provided with non-return valve in the outlet of muffler, non-return valve with link to each other with the hyperbaric chamber; Base is provided with heat dam; Thermal insulation board is provided with the air guide oblique wave.After adopting said structure, heat-conducting medium is heated to come to life after certain temperature and produces gasification, flows into low-pressure chamber through the condenser cooling, produces self-loopa, reaches the effect of heat radiation; Have simple and compact for structure, advantages such as working stability is reliable, thermal resistance is little, good heat dissipation effect, not power consumption.

Four, description of drawings

Fig. 1 is an appearance structure synoptic diagram of the present invention.

Fig. 2 is a structural representation of the present invention.

Five, embodiment

Fig. 1, shown in Figure 2, the specific embodiments of computer PCD heating radiator for invention, it comprises base 9, base 9 is the sealed chamber of hollow, the thermal insulation board 7 that is arranged in the base 9 is separated into hyperbaric chamber 14 and low-pressure chamber 15 to chamber, thermal insulation board 7 is provided with the air guide oblique wave, is convenient to produce the gas channeling of vaporization, and thermal insulation board 7 is made by heat-barrier material; Condenser 1 is arranged on the base 9, condenser 1 is by the brake forming of flat radiating tube and be fixed on the base 9, the import of condenser 1 links to each other with hyperbaric chamber 14 by Connection Block 3, in Connection Block 14, be provided with unidirectional air outlet valve, unidirectional air outlet valve is made up of valve body 5, spring 2 and special garden pearl 4, and spring 2 and special garden pearl 4 are arranged on the top of valve body 5; The outlet of condenser 1 links to each other with muffler 8, muffler 8 reaches the bottom of low-pressure chamber 15, outlet at muffler 8 is provided with non-return valve, non-return valve links to each other with hyperbaric chamber 14, non-return valve is made up of check spring 12, non-return garden pearl 11 and return-air cover 10, return-air cover 10 is fixed on the muffler 8, and non-return garden pearl 11 and check spring 12 are located in the return-air cover 10, and the pod apertures 16 that return-air overlaps 8 bottoms communicates with hyperbaric chamber 14; Base 9 is provided with heat dam 13.

Before the use, at first will be in the sealed chamber of base 9 of the present invention filling heat-conductive medium 6 and being evacuated.During application, computer PCD is close in the bottom installs.Behind computer operation, PCD constantly produces heat, cause heat-conducting medium 6 temperature in the hyperbaric chamber 14 constantly to raise, after the temperature of heat-conducting medium 6 is raised to certain numerical value, heat-conducting medium 6 vaporization that comes to life, room pressure raises, open unidirectional guide valve, gas becomes flow of liquid through condenser 1 pipeline condensation and goes into base pressure chamber 15, and non-return valve was opened after muffler 8 was put aside certain liquid, and cooled heat-conducting medium 6 reenters hyperbaric chamber 14.The heat-conducting medium 6 boiling-vaporization-condensation of being heated, so constantly circulation makes heat energy that computer PCD produces by condenser 1 heat exchange, thereby reaches the purpose of heat radiation.Adopt the utility model structure, thermal resistance is little, good heat dissipation effect, working stability reliably, not power consumption, cost be low.Compare with existing fan electromotor radiating effect, its radiating effect will improve about 10%, is the desirable substitute of present computer PCD.
