HEAT PIPE STRUCTURE OF A HEAT RADIATOR
The present invention provides a heat pipe structure of a heat radiator, which includes two vertically protruded radiating portions and heat-absorbing portions at a bottom of the two radiating portions. The heat-absorbing portions are assembled onto the heat-conducting pedestal. Two turning portions are formed at the intersection of the heat-absorbing portions and two radiating portions. The heat-absorbing portion has a curved shape. The heat-absorbing portions of adjacent heat pipes are misaligned, such that the turning portion of the heat-absorbing portion of one heat pipe aligns with the recessed space of the other heat pipe. A minimum of heat pipe assembly space obtains a maximum heating area, thus greatly improving the heat-radiating effect and reducing the manufacturing cost with better applicability and economic efficiency.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to a heat radiator, and more particularly to a heat radiation with an innovative heat pipe structure.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
The heat radiator of the present invention permits a preset quantity of heat pipes to be assembled onto a heat-conducting pedestal. Each heat pipe is also fitted with some fins to improve the radiating efficiency.
The typical structure of a heat radiator is depicted in
However, the following shortcomings are observed in actual applications. Owing to a smaller heating area of a straight heat-absorbing portion 22 of the heat pipe 20, the heat-conducting pedestal 10 shall be expanded if you intend to increase the length and area of heat-absorbing portion 22. This will bring about higher manufacturing costs and assembly area, making it difficult to put into service, let alone the limitations of radiating objects (CPU) and assembly space. Moreover, the heating area could be increased by adding a number of heat pipes 20, but this will lead to higher costs. The straight heat-absorbing portions 22 of heat pipe 20 play a relatively smaller role in heat radiation.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
BRIEF SUMMARY OF THE INVENTIONBased upon the innovative present invention, the heat pipe structure of a heat radiator has heat-absorbing portions designed into a curved shape and is also misaligned, so that the minimum heat pipe assembly space could maintain a maximum heating area. As compared with typical heat pipe structures of the prior art, the curved heat-absorbing portions of the heat pipe could yield multiplication of the heat-absorbing effect (e.g. -shaped heat-absorbing portion versus typical straight heat-absorbing portion), thus greatly improving the heat conduction and reducing effectively the manufacturing cost of heat pipe. Furthermore, the heat-absorbing portions of adjacent heat pipes are misaligned, so the assembly space for a plurality of heat pipes could be minimized to meet the trend of miniaturized product design. It is learnt that the overall design of the present invention could improve significantly the radiating effect of heat pipes, reduce the manufacturing cost and yield better industrial performance.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
The feature of the present invention includes the heat-absorbing portion 32 in a curved shape to form a recessed space 34.
Also, the heat-absorbing portions 32 of two adjacent heat pipes 30 are staggered, namely, the turning portion 33 of heat-absorbing portion 32 of one heat pipe 30 aligns with the recessed space 34 of the other heat pipe 30.
Two turning portions 33 of heat-absorbing portions 32 of said heat pipe 30 are flushed correspondingly. Referring to
The protruding ends 310 of said radiating portions 31 are flushed as shown in
The curved heat-absorbing portion 32 of the heat pipe 30 is provided with a U-shaped pattern (shown in
