Problems solved by technology

Therefore, high-quality ultra-thin TVs often have a rapid increase in thermal power due to the accumulation of too many LEDs in a small space. The traditional method of using aluminum extrusions (aluminum profiles) for natural convection cooling can no longer meet the needs of new TVs. demanded

Abstract

The invention provides a water cooling system for an LED display module and the LED display module. The water cooling system comprises a heat exchange pipe arranged on an LED backlight source. The heat exchange pipe is connected with an inlet of a water pump inlet. An outlet of the water pump is connected with a first master pipe. At least one branch pipe is arranged on the first master pipe. The branch pipe is provided with cooling fins, and passes through the cooling fins to be connected with a second master pipe. The second master pipe and the first master pipe are arranged opposite to each other. The second master pipe is connected with the heat exchange pipe to form a flow loop. Water-cooling liquid is filled in the heat exchange pipe. The invention further provides the LED display module. The display module comprises a backlight board and the water cooling system for the LED display module. Compared with the prior art, through the arrangement of the water cooling system behind the backlight board, the water heated by the LED backlight source is pumped to pass through the heat exchange pipe to enter the first master pipe, and then passes through cooling fin tubes where the heat of the water-cooling liquid is exchanged, thus the flow loop is formed to achieve the goal of cooling.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a water cooling system for LED display modules and the LED display module. Background technique [0002] With the advancement of technology, TV sets have already entered thousands of households as a necessary home appliance. However, people nowadays have higher and higher requirements for visual enjoyment, which makes various manufacturers keep trying to use various technologies to improve the display effect of TV screens; It is often necessary to use more LED backlight light-emitting elements LED; in addition, the thinning of TV sets is also the trend of the times, so the current ultra-thin TVs often use the side-light input method. Therefore, high-quality ultra-thin TVs often have a rapid increase in thermal power due to the accumulation of too many LEDs in a small space. The traditional method of using aluminum extrusions (aluminum profiles) for natural convec...
