Problems solved by technology

[0007] However, this design still has disadvantages, because the heating elements in the industrial computer are not only the central processing unit and the north bridge chip, although the other elements have a low degree of heat generation, they will still increase the temperature inside the casing if accumulated for a long time
It is the most direct way to set each heating element with a heat conduction element, but it is not economical

Embodiment Construction

[0020] Generally speaking, electronic devices with closed casings are industrial computers and embedded computers with high dustproof and waterproof requirements. The International Protection Code (IP Code) is the International Electrotechnical Commission (International Electrotechnical Commission, The dustproof and waterproof level specifications for electronic devices formulated by IEC). The first digit after the IP Code indicates the dustproof level, and the second digit indicates the waterproof level. The larger the number, the higher the protection level. The closed case in the embodiment of the present invention is defined as a closed case with an electronic device protection level above IP45. In the following description, the electronic device of the present invention will take an industrial computer as an example.

Abstract

The invention discloses an electronic device which comprises a sealing shell, a heat conducting element and a fan, wherein the heat conducting element penetrates the sealing shell, and the fan is arranged in the sealing shell. The fan generates an air flow which flows in the sealing shell and flows through the heat conducting element. Air in the sealing shell is driven to flow by the fan arrangedin the sealing shell so as to conduct heat out of the shell through the heat conducting element which penetrates the sealing shell, thus local accumulation of the heat in the sealing shell can be avoided. Moreover, heat convection is also reinforced so as to improve the efficiency of heat exchange with outside cold air, thus the invention provides a more effective heat exchange mechanism which enables the electronic device with the sealing shell to operate more stably.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an electronic device with a closed casing. Background technique [0002] Industrial computers refer to computers that are not used for general consumer or commercial purposes. Because they are not only used in industrial fields, some people call them industrial computers. With the development of 3C and the development of the Internet, the industrial computer industry has combined information, communications, consumer electronics, optoelectronics, semiconductors, and software to continuously expand its application fields, and gradually extend from industrial applications to daily life. In addition, the use environment of industrial computer products is usually poor, so the products often require high temperature resistance, low temperature resistance, good heat dissipation, dustproof, waterproof and other characteristics. [0003] Because industrial computers have high requirem...
