Heat dissipation structure of plasma display screen

Abstract

The invention discloses a heat dissipation structure of a plasma display screen. According to the technical scheme, the heat dissipation structure comprises a display screen, a cooling fin is fixedlyinstalled at the left end in the display screen, the left end of the display screen is connected with a rear cover in a clamped mode, the outer wall of the rear cover is connected with a heat dissipation device in a sleeved mode, a fixing device is arranged in the heat dissipation device, and the right end in the display screen is connected with vacuum glass in a clamped mode. A main board is arranged at the left end of the vacuum glass, the right end of the cooling fin is connected with a first copper pipe and a second copper pipe, the first copper pipe is bonded to the left end of the outerwall of the vacuum glass, the second copper pipe is bonded to the middle of the left end of the outer wall of the main board, and the left end of the outer wall of the cooling fin is connected with aninner cooling fan in a clamped mode. The heat dissipation structure has the beneficial effects that the temperature generated by the vacuum glass and the main board is reduced, and the situation thatthe display is fuzzy or the brightness is reduced due to the fact that plasmas emitted by the vacuum glass are influenced by heat is prevented, and therefore the service life of the plasma display screen is prolonged.

Description

technical field [0001] The invention relates to the field of plasma display screens, in particular to a heat dissipation structure of a plasma display screen. Background technique [0002] Plasma display, also known as plasma display, is a flat display screen. The light is emitted from the ions between two pieces of glass to the phosphor. Unlike liquid crystal displays, the emitted gas does not contain mercury, but uses Passive gas mixed with neon and xenon, this gas is a harmless gas; [0003] Plasma displays are very bright, can display more colors, and can also produce larger display screens, with a maximum diagonal of 381 cm. The contrast of plasma display screens is also high, and it can produce a full black effect, which is great for watching movies. Especially suitable, the thickness of the display screen is only 6 cm, and the thickness of other circuit boards is only 10 cm; [0004] The principle of plasma light emission is to inject inert gas or mercury vapor into...

Problems solved by technology

[0008] For this reason, the present invention provides a kind of heat dissipation structure of plasma display screen, first copper pipe and second copper pipe are bonded by vacuum glass and the left end of main board outer wall, and first copper pipe and second copper pipe are connected to the right end of radiator fin outer wall, heat dissipation The outer wall of the left end of the chip is snapped to the inner cooling fan, and then the cooling device is inserted through the outer wall of the back cover to solve the problem of blurred display or reduced brightness, which will affect the service life of the plasma display.
