The present invention relates to a heat dissipating structure of an industrial computer, and more particularly to an improved heat dissipating structure that facilitates changing a heat dissipating fan module in an industrial computer.
In general, a major difference between an industrial computer and a personal computer resides on that the appearance of the personal computer can be designed with changes according to the consumer requirement and preference, and the industrial computer must be designed in accordance with other equipments for an automated operation and in compliance with the requirements of saving working spaces and avoiding a large ineffective working space, and thus most industrial computers come with an appearance of a cuboid having fixed length and width and a height equal to an integral multiple of a universal standard. Since the industrial computers produce a large quantity of heat during their operation, the cuboidic casing of the industrial computer generally includes a heat dissipating module comprised of heat dissipating fins and fans for dissipating the heat. Due to the short life expectancy of a fan or the attachment of dusts from the air, the fan may fail or have a poor efficiency easily after being used for a while. Thus, users have to turn off the industrial computer and remove the casing before changing the fan or clean the dusts on the fan. Obviously, such arrangement is very inconvenient to users. Furthermore, vibrations may be produced during the operation of the heat dissipating fans and bad tracks may be produced by the vibrations when accessing a hard disk of the industrial computer, and the bad tracks will affect the overall operation of the industrial computer. Therefore, the aforementioned design of a general industrial computer with an installed heat dissipating module is unable to meet the requirements of the application.
As described above, it is an important subject for manufacturers and designers to develop a heat dissipating structure that provides an easy and convenient way of installing the heat dissipating module and preventing the vibrations produced by the heat dissipating fans or the adverse effects on the industrial computer without affecting the heat dissipation of the industrial computer.
It is a primary objective of the present invention to provide an improved heat dissipating structure of an industrial computer that can achieve the effect of changing the heat dissipating structure easily without affecting the heat dissipation of the industrial computer.
To achieve the foregoing objective, the present invention provides an improved heat dissipating structure of an industrial computer, comprising: a heat dissipating module and two fixing units installed on both lateral sides of a top surface of the heat dissipating module, and the heat dissipating module includes a detachable heat dissipating fan module therein, and the fixing unit is secured integrally with the heat dissipating module and the industrial computer by a plurality of fixing elements to facilitate a change of a heat dissipating fan module.
Another objective of the present invention is to provide an improved heat dissipating structure of an industrial computer to achieve a vibration-proof effect without affecting the heat dissipation of the industrial computer.

In view of the shortcomings of the heat dissipating module that the industrial computer may cause tremendous inconvenience for the change of a heat dissipating module and produce vibrations that will affect the operation of the industrial computer, the present invention provides an improved heat dissipating structure to overcome the foregoing shortcomings of the prior art.
Refer to
Since the heat dissipating fan module 111 is rotated at a high speed to drive cold air into the industrial computer 10 for dissipating the heat, the high-speed rotation produces vibrations that will affect the normal operation of the industrial computer 10. Therefore, the present invention provides a three-axes fixing design to achieve a vibration-proof effect of the industrial computer 10. In the present invention, the heat dissipating structure of the industrial computer comprises a heat dissipating module 11 and two fixing units 12 installed on both lateral sides of a top surface of the heat dissipating module 11. Both lateral sides of the heat dissipating module 11 separately have a fixing base 115, and a lateral side of the fixing unit 12 is integrally secured with a lateral side of the fixing base 115 by a plurality of fixing elements 13, and a top side of the fixing base 115 is integrally secured with a bottom side of the industrial computer 10 by a plurality of fixing elements 14, and both lateral sides of the fixing unit 12 separately have a fixing protruded plate 121 for integrally securing the front, rear and lateral sides of the industrial computer 10 by a plurality of positioning elements 15. If the fixing base 115 and the fixing unit 12 of the heat dissipating module 11 are integrally secured with the industrial computer 10 by the fixing elements 13, 14, 15, a three-axes locking mode is formed. Even if there are vibrations produced during the high-speed rotation of the heat dissipating fan module 111 for the heat dissipation, the vibrations will be absorbed by the locking positions of the fixing base 115 and the fixing unit 12 of the heat dissipating module 11 with the industrial computer 10. In other words, the three axes including the x-axis, y-axis and z-axis of the industrial computer 10 will offset the action of the vibrations, so that the vibrations will not be transmitted to the industrial computer 10, and the invention definitely can achieve the vibration-proof effect.
To enhance the vibration-proof effect, the fixing element 13, 14, 15 can be designed as an element comprised of a rubber member and a screw, wherein the screw provides a locking function, and the rubber member provides a vibration absorbing function to improve the overall vibration-proof effect greatly.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
