Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heat exchanger is installed in the rear space of the display to increase heat conductivity, then heat exchange efficiency is improved, but the thickness of the display device increases
Solution Approach 1:
The patent transitions from a traditional rear-mounted heat exchanger to a side-mounted heat exchanger configuration. The heat exchanger is positioned at the side of the display device rather than the rear, allowing heat to be dissipated laterally through side surfaces. This dimensional change enables effective heat exchange without increasing the thickness of the display device, as the heat dissipation path extends in the lateral direction rather than the depth direction.
2Reliability
If a heat exchanger with larger area is installed to increase heat conductivity, then heat exchange efficiency is improved, but the volume of the display device increases
Solution Approach 1:
The patent utilizes the side surface area of the display device for heat exchange purposes. By positioning the heat exchanger at the side and utilizing lateral heat dissipation, the effective heat exchange area is increased without requiring additional depth or volume. The heat exchanger integrates with the side surface structure, converting what would be unused side surface area into effective heat dissipation area.
3Reliability
If a complex air circulation pathway is used to cool the display, then cooling effectiveness is improved, but the structure becomes more complex and difficult to manufacture
Solution Approach 1:
The patent extracts the heat exchanger from the internal rear space and positions it at the side of the display device. This extraction simplifies the air circulation pathway by eliminating the need for complex internal ducting and circulation systems. The heat exchanger directly accesses ambient air at the side, allowing for a simpler, more straightforward cooling configuration that is easier to manufacture and maintain.

AI summary
The present invention relates to: a cooler capable of simplifying a structure, increasing heat exchange efficiency, and slimming a display device; and a display device using the same. A cooler structure applied to the display device uses a heat pipe allowing a refrigerant, which is a volatile liquid, to flow therein and a fin structure expanding a heat transfer cross section, so as to rapidly absorb, through evaporation of the refrigerant, heat from the air in a closed air circulation path circulating around a display unit, and quickly dissipate heat from an outside space (an open air circulation path) of the closed air circulation path through condensation of the refrigerant, thereby enabling heat exchange to occur very efficiently while occupying less volume. Additionally, the present invention provides the cooler structure in which the heat pipe is made in a circular fashion such that the refrigerant efficiently flows therein. Particularly, when a section in which the heat pipe generates heat is disposed on the side of the display unit, the display device can be formed to be just as slim.
