Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the present invention provides a monitoring display device heat dissipation structure, including: the heat dissipation structure comprises a rear cover plate 1, a plurality of heat dissipation fins 2 arranged on the rear cover plate 1, and heat conduction fins 3 connected with the heat dissipation fins 2. Be provided with PCBA mainboard 41 on the back shroud 1, be provided with chip 42 on the PCBA mainboard 41. The rear cover plate 1 is provided with a through hole 11. One end of the heat conducting fin 3 is in contact with the chip 42, and the other end of the heat conducting fin 3 is turned upwards along the side wall of the rear cover plate 1, penetrates through the through hole 11 and is connected with the radiating fin 2. Electronic components on the PCBA motherboard 41, particularly the chip 42 on the PCBA motherboard 41, generate a large amount of heat during operation, and contact the chip 41 through one end of the heat-conducting sheet 3, so that the heat generated during operation of the chip 42 is conducted out. The heat conducting fin 3 is in contact with the heat radiating fin 2, so that heat generated by the chip 42 is transferred to the heat radiating fin 2, and the heat is radiated to the outside so as to cool and radiate the inside of the display device. The heat conducting fins 3 are turned upwards along the side wall of the rear cover plate 1, and the turned parts are in contact with the side wall of the rear cover plate 1, so that auxiliary heat dissipation is performed, and heat dissipation is accelerated.
The radiating fins 2 are provided with a plurality of radiating ribs 21. By providing the ribs 21, the contact area of the heat sink 2 with the outside air is increased, thereby accelerating the heat dissipation.
Referring to fig. 4 and 5, the housing of the rear cover plate 1 is provided with a plurality of heat sink installation grooves 12, and the heat sink 2 is disposed in the heat sink installation grooves 12. A connecting piece 22 is arranged between two heat sinks 2 arranged in the two adjacent heat sink mounting grooves 12. Through setting up a plurality of fin 2 to connect adjacent fin 2 through connection piece 22, thereby increase fin 2's the area that sets up for thermal transmission and giving off, reinforcing radiating effect.
The radiating fins 2 and the heat conducting fins 3 are made of heat conducting metal sheets. The heat conducting metal sheet has good heat conducting and radiating effects, and meets the requirements of heat radiation and cooling.
The radiating fins 2 are made of aluminum alloy. For the copper sheet, the heat dispersion of aluminum alloy is stronger, and fin 2 need contact with the external world moreover, can form fine and close oxide film after the aluminum alloy oxidation, nevertheless can not cause the influence to heat conduction, the heat-sinking capability of aluminum alloy, and heat conduction and heat dispersion can significantly reduce after the copper sheet oxidation, therefore better radiating effect can be played to fin 2 of aluminum alloy material.
The heat conducting strip 3 is made of a copper sheet. The heat conductivility of copper sheet is stronger than the aluminum alloy, simultaneously because conducting strip 3 sets up in monitoring display device inboard, is difficult to take place the oxidation, can ensure that conducting strip 3's heat conductivility is more stable.
To sum up, the utility model discloses a conducting strip contacts with the thermal electronic components of production to the heat transfer with electronic components dispels the heat to fin department, thereby for monitor display device provides good radiating effect, ensures that the inside electronic components of monitor display device can not damage because of the heat of collecting together too high, with extension monitor display device's life.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
