Description

FIELD OF THE INVENTION

The present invention generally relates to a heat dissipating system and device, and more particularly to a heat dissipating system that effectively lowers the temperature of a heat source and improves the heat dissipating performance by using a compressor to carry a cooling fluid to disperse the heat produced by the heat source.

BACKGROUND OF THE INVENTION

As components of air conditioners or heaters used for automobiles and home electric appliances are developed rapidly, the heat produced by such applicants becomes more and the internal temperature of the automobiles and home electric appliances also increases and seriously affects the stability of the operation of electronic components. Therefore, manufacturers usually build ventilation holes or a fan on a sidewall of the automobile and home electric appliances to enhance air convection, so that the hot air in automobile and home electric appliances can be discharged to the outside rapidly to assure the stability of the operation of electronic components.
At present, computer applications are used extensively in all areas of our life. As the speed of data processing is increased constantly, the heat produced during the operation of computer devices is increased as well. Thus, finding a solution for timely dissipating the heat for a normal computer operation demands immediate attention.
The structure of prior art heat dissipating devices used for personal computers or notebook computers generally includes a plurality of vertical heat dissipating fins connected to the top of a metal base and a plane disposed at the bottom of the base. An eccentric tool is used to install the heat dissipating device onto a heat generating component in a computer, such that the lower plane surface is in close contact with the heat generating component. A fan is mounted onto the heat dissipating fins. When the computer is operating, the heat produced by the computer components passes through the plane of the heat dissipating device to the base of the heat dissipating device according to the principle of heat conduction. The heat is further conducted to the heat dissipating fins and carried away by the air flow of the fan. Such arrangement simply relies on the efficiency of the thermal conduction of the metal and depends on the thermal conductivity of the material of the heat dissipating device. Since the thermal conductivity of a solid is low, the prior art heat dissipating device gives poor heat dissipating effects and has low practicability.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to overcome the shortcomings of the prior art by providing a heat dissipating system and device, wherein the heat dissipating system comprises two pipelines separately installed on a side of a compressor and connected to an end of a heat dissipating device, and the other end of the heat dissipating device includes two pipelines, and one of the two pipelines is connected to an expansion valve and then to an evaporator, and the other one of the two pipelines is connected to the evaporator, such that the heat dissipating system is fixed onto the internal surface of the air conditioner or heater of automobile and home electric appliances or computer systems. The heat produced by these appliances passes through the plurality of heat dissipating fins of the heat dissipating device, and the heat is dispersed by the operation of conductive media in an upper and a lower circuits.
Unlike the prior art fans or heat dissipating devices, the present invention has a heat dissipating effect as follows:
The heat dissipating device of the invention has a plurality of heat dissipating fins with non-interconnected upper and lower circuits and these heat dissipating fins are coupled with the combining tubes on both sides. A multilayer channel is partitioned by the horizontal partition and the plurality of vertical partitions of the two combining tubes, and the compressor is used to absorb, discharge and reabsorb the heat by the liquid-gas-liquid circulating mode of a cooling fluid. The operating heat produced by the heat source of the electronic components is absorbed by the foregoing heat dissipating fins. Therefore, a large amount of heat energy produced by the heat source is carried away rapidly that changes the traditional heat dissipating method of using a single metal conduction and thus greatly improves the stability of the operation of electronic components and the heat dissipating performance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment and the attached drawings for the detailed description of the invention.
Referring to FIG. 1, the present invention is applied for the electronic components of an air conditioner or a heater of automobile and home electric appliances or computer systems and other equipments with a heat source. The invention is used to reduce the heat source and improve the heat dissipation and operating performance of a heat dissipating system 1. The heat dissipating system 1 comprises: a compressor 2 having two pipelines 20, 21 separately disposed on a side of the compressor 2, a heat dissipating device 3 for connecting a first combining tube 30 of one of the two pipelines 20, 21 from the compressor 2 and defining a multilayer channel by the internal sides of the first combining tube 30 and a second combining tube 31 having the same shape of the first combining tube 30 and a plurality of heat dissipating fins 31 disposed in the middle of the first and second combining tubes 30, 31 and having non-interconnected upper and lower circuits 340, 341, wherein the first combining tube 30 has two pipelines 20, 21 separately and externally coupled to an inlet 200 and an outlet 210 of the two pipelines 20, 21 which are installed separately on a side of the compressor 2; an expansion valve 4 having an end coupled to a pipeline 32 of the second combining tube 31 of the heat dissipating device 3 and a pipeline 40 coupled to the expansion valve 4; and an evaporator 5 having an inlet 50 disposed at an end and coupled to the pipeline 40 on the expansion valve 4 and an outlet 51 disposed at another end and coupled to another pipeline 33 of the second combining tube 31 of the heat dissipating device 3 to define a circulated heat dissipating channel.
The foregoing combining tubes 30, 31 (as shown in FIGS. 2, 3A, 3B and 4) on both sides are ellipsoids or tetrahedrons. Upper spaces 3001, 3101 and lower spaces 3002, 3102 are partitioned by horizontal partitions 3000, 3100 disposed in the middle of the two combining tubes 30, 31, and connecting pipes 300, 301, 310, 311 are disposed at the upper and lower opposite corners of the two combining tubes 30, 31. The two combining tubes 30, 31 have a plurality of embedding holes 302, 312 disposed on the external side and a plurality of rectangular holes 303, 313 disposed on the internal side, such that the plurality of embedding holes 302, 312 and the plurality of rectangular holes 303, 313 at their internal side can be engaged with a plurality of vertical partitions 35 and a plurality of heat dissipating fins 34 of the same shape. The two combining tubes 30, 31 at their respective end have a cover 36 with a protruded member 360 coupled to the upper and lower spaces 3001, 3101, 3002, 3102 of the two combining tubes 30, 31.
Referring to FIGS. 3A, 3B and 4, the plurality of vertical partitions 35 is inserted into the plurality of the embedding holes 302, 312 disposed on the external side of the two combining tubes 30, 31 of the foregoing heat dissipating device 3, and the cover 36 is installed at the distal ends of the two combining tubes 30, 31. In the meantime, the plurality of rectangular holes 303, 313 disposed on the internal sides of the two combining tubes 30, 31 is coupled with the plurality of heat dissipating fins 34 to define a circulating channel, such that the heat dissipating system 1 can effectively dissipate the heat of a heat source (as indicated by the arrows in FIG. 4). Upper and lower circuits 340, 341 of the plurality of heat dissipating fins 34 of the heat dissipating device 3 are operated in the two combining tubes 30, 31 having a multilayer channel, so as to improve the heat dissipating performance of the plurality of heat dissipating fins 34 and the two combining tubes 30, 31.
Referring to FIGS. 1 and 4, the compressor 2 disposed at one side of the heat dissipating system 1 dissipates the heat produced during the operation of the heat generating components such as the air conditioner or heater of automobile and home electric appliances or electronic components of computer systems by circulating conductive media of a cooling fluid (as indicated by the arrows in FIG. 4). The cooling fluid passes through the outlet 200 of the pipeline 20 disposed at one side of the compressor 2 to the first combining tube 30 disposed at an end of the heat dissipating device 3. The cooling fluid enters a connecting pipe 300 above the combining tube 30 through the upper space 3001 partitioned by the horizontal partition 3000 in a horizontal direction to an inlet 3400 at an end of the upper circuit 340 of the heat dissipating fins 34, so that the heat is dispersed by the conductive media (as indicated by the arrows in FIG. 4) through an outlet 3401 at another end of the heat dissipating fins 34 to the second combining tube 31 disposed at another end of the heat dissipating device 3, and then discharged from the upper space 3101 partitioned by the horizontal partition 3100 in a horizontal direction. The cooling fluid is returned through a connecting pipe 310 above the combining tube 31 to an inlet 4000 disposed at an end of an expansion valve 4 which is connected to the pipeline 32, and the pipeline 40 goes through an outlet 401 above the expansion valve 4 and then enters into the evaporator 5 from the inlet 50 at an end of the evaporator 5. The cooling fluid passes through another outlet 51 at another end of the evaporator 5. Another pipeline 33 is used to send the cooling fluid from another end of the second combining tube 31 into the lower space 3102 partitioned by the horizontal partition 3100 in a horizontal direction, and then the cooling fluid passes through an inlet 3410 at another end of the lower circuit 341 of the heat dissipating fins 34 to an outlet 3411 at another end of the heat dissipating fins 34 and then flows into the lower space 3002 partitioned by the horizontal partition 3000 in a horizontal direction of the first combining tube 30 at another end of the heat dissipating device 3. At last, the cooling fluid flows into the inlet 210 at an end of another pipeline 21 of the first combining tube 30 and out from an outlet 211 at another end of another pipeline 21 into the compressor 2, so as to define a circulated channel. Therefore, the heat of the heat source (as indicated by the arrows in FIGS. 5 and 6) is dispersed from the multilayer channel formed by the plurality of heat dissipating fins 34 and the horizontal partitions 3000, 3100 and the plurality of vertical partitions 35 of the two combining tubes 30, 31. The conductive media of the cooling fluid in the plurality of heat dissipating fins 34 absorbs the heat transmitted from the heat generating components, and the low-temperature accessories of the heat dissipating device cools down the temperature by converting the cooling fluid from a gaseous state into a liquid state in order to release the heat to the heat dissipating device 3. The conductive media go through the changes of liquid-gas-liquid phases for repeatedly carrying out the process of absorbing-releasing-reabsorbing heat, and finally the heat is carried away by the air flow of a fan through the heat dissipating device 3. With the dual heat dissipating effects, the heat dissipation of the heat dissipating device 3 is improved greatly.
Referring to FIG. 7, this embodiment is substantially the same as the embodiment as illustrated in FIG. 2 with an exception of having a circular hole 350 a on the vertical partition 35 a.
Referring to FIG. 8, this embodiment is substantially the same as the embodiment as illustrated in FIG. 2 with an exception of having air pipes 30 a, 31 a in the square shape, wherein the two air pipes 30 a, 31 a have horizontal partitions 300 a, 310 a to separate upper spaces 301 a, 311 a and lower spaces 302 a, 312 a, and a cover 32 a with a protruded member 320 a disposed at the two combining tubes 30 a, 31 a and coupled to the upper and lower spaces 301 a, 311 a, 302 a, 312 a of the two combining tubes 30 a, 31 a.
