BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to frame-type computer cooling devices, and more particularly, to a frame-type computer cooling device easy to install and efficient in dissipating heat from a heat-generating source in a host computer.

2. Description of Related Art

Recent years see evolution of ever-changing technologies, and thus computers are indispensable to the handling of routine at both an individual level and a corporate level. To be increasingly versatile, computers nowadays are equipped with an increasing number of electronic components more complicated than ever before, for example, CPU, chips, and expansion cards. All the electronic components in operation generate heat and thereby become so-called heat-generating sources. The heat generated by the electronic components is ever-increasing because of a continuous increase in both the data processed by computers and the speed thereof.

Usual means to heat dissipation of the aforesaid heat-generating sources are, namely cooling fans, cooling fins, heat pipes, and other heat-dissipating components. In this regard, a cooling circulation device is one of the feasible means to enhancement of efficiency in heat dissipation.

Nonetheless, cooling circulation devices are composed of various components, namely evaporators, compressors, condensers, expansion valves, etc. It is well known that host computers are equipped with a variety of electronic parts and electronic devices, thus leaving little usable space. Despite their high efficiency in heat dissipation, the cooling circulation devices mentioned above pose a challenge in space utilization when installed in host computers.

Accordingly, the purpose of the present invention is to disclose a frame-type computer cooling device easy to install and efficient in dissipating heat from a heat-generating source in a host computer.

Hence, the inventor endeavored to devise a frame-type computer cooling device based on the inventor's expertise and experience in the art. The frame-type computer cooling device is easy to install and efficient in dissipating heat from a heat-generating source in a host computer.

It is a primary objective of the present invention to provide a frame-type computer cooling device easy to install and efficient in dissipating heat from a heat-generating source in a host computer by the improvement of the structure.

To achieve the above and other objectives, the present invention provides a frame-type computer cooling device for installation in a host computer having a heat-generating source and a slot compartment. The slot compartment communicates with the inside of the host computer and the outside of the host computer.

The frame-type computer cooling device of the present invention mentioned above comprises a frame and a cooling circulation device. The frame is insertedly disposed in the slot compartment and comprises a receiving recess. The cooling circulation device comprises an evaporator, a compressor, a condenser, and an expansion valve connected to one another by a pipeline filled with a coolant.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention is herein illustrated with specific embodiments and drawings, so that one skilled in the pertinent art can easily understand the objective, features, other advantages and effects of the present invention from the disclosure of the invention.

Referring toFIG. 1andFIG. 2,FIG. 1is an exploded view of a first preferred embodiment of the present invention.FIG. 2is a three dimensional view of the first preferred embodiment of the present invention. As shown in the drawings, a frame-type computer cooling device2of the present invention comprises a frame22and a cooling circulation device21.

As shown in the drawings, the frame22comprises a receiving recess221and a bottom plate222, and the cooling circulation device21comprises an evaporator211, a compressor212, a condenser213, and an expansion valve214. The evaporator211, the compressor212, the condenser213, and the expansion valve214are connected to one another by a pipeline215. The pipeline215is filled with a coolant216. The compressor212, the condenser213, and the expansion valve214are received in the receiving recess221of the frame22and disposed on the bottom plate222.

In the first preferred embodiment, the pipeline215mentioned above is a soft hose or a hard pipe. In addition, a cooling fan218is disposed above the condenser213.

Referring toFIGS. 1,2and3,FIG. 3is a schematic view showing the use of the first preferred embodiment of the present invention. As shown in the drawings, the frame-type computer cooling device2is installed in a host computer1. The host computer1comprises a heat-generating source11and a slot compartment12. The slot compartment12communicates with the inside of the host computer1and the outside of the host computer1. In the first preferred embodiment, the heat-generating source11is a CPU.

Additionally, as regards installation, the frame22is insertedly disposed in a slot compartment12of the host computer1, and the evaporator211of the cooling circulation device21adjoins the heat-generating source11of the host computer1.

In the first preferred embodiment, the slot compartment12of the host computer1is 4U-sized, and the frame22is 4U-sized. The notation “4U”, a jargon in wide use in the computer industry, refers to the dimensions of the slot compartment12and the frame22or the dimensions of a server, and comes in various degrees, such as 1U, 2U, etc. Hence, the aforesaid notation is well understood by persons ordinarily skilled in the art and therefore is not described in detail herein.

With the above structure, heat dissipation of the heat-generating source11of the host computer1takes place by means of cooling circulation. The principle of cooling circulation of the evaporator211, the compressor212, the condenser213, and the expansion valve214is a general thermofluidic principle and therefore well understood by persons skilled in the art.

With the above structure, moreover, installation of the frame22and the cooling circulation device21in the host computer1is convenient and free of the problems facing the prior art, such as space utilization. In other words, with the above structure, installation of the cooling circulation device21is easy and convenient, and thus heat from the heat-generating source11in the host computer1is dissipated swiftly and efficiently.

Referring toFIG. 4andFIG. 5,FIG. 4is a three dimensional view of a second preferred embodiment of the present invention.FIG. 5is a schematic view showing the use of the second preferred embodiment of the present invention.

The second preferred embodiment is substantially the same as the first preferred embodiment in main structures, but the second preferred embodiment is distinguished from the first preferred embodiment by the following features of the second preferred embodiment: the host computer1further comprises another heat-generating source13, such as a chip; the cooling circulation device21further comprises another evaporator217; the evaporator217adjoins the heat-generating source13; the pipeline215is connected to another pipeline219in parallel; and the pipeline219is connected to another evaporator217. Likewise, the pipeline219is a soft hose in this embodiment.

Therefore, the above structure can vary flexibly when necessary. That is, for instance, where a host computer has a plurality of heat-generating sources, synchronous heat dissipation of the heat-generating sources can be accomplished by the above structure.

The purpose of parallel connection of pipelines is to preclude a problem which might otherwise occur when pipelines are connected in series, that is, series-connected pipelines are less efficient in heat dissipation, because heat from a heat-generating source affects the next heat-generating source.

In conclusion, the present invention meets the three patentability criteria, namely not anticipated (novelty), not obvious (non-obviousness), and useful (industrial applicability). The present invention is neither anticipated nor obvious, as the improved structure disclosed in the present invention provides ease of installation and enables efficient heat dissipation of a heat-generating source in a host computer. The present invention has industrial applicability, as products derived from the present invention can meet current market needs.

It is apparent to those skilled in the art that the foregoing specific embodiments are only illustrative of the features and functions of the present invention but are not intended to restrict the scope of the present invention. It is noted that all equivalent modifications and variations made in the foregoing embodiment should fall within the scope of the invention. Accordingly, the disclosure of the present invention should be defined by the appended claims.
