Description

Technical Field

[0001] The utility model relates to the field of monitors, in particular to a cooling and heat dissipation mechanism of a monitor host. Background Art

[0002] At present, a Chinese utility model with a publication number of CN214960581U discloses a heat dissipation cover for a PiCCO capacity monitor, including a shell, a body radiator and a power cord. The shell is provided with a placement space connected to the outside of the shell. The body radiator includes a connection shell and a heat dissipation body. The connection shell is passed through the shell. A vacuum suction cup is provided at one end of the connection shell facing the placement space. The heat dissipation body is provided at one end of the connection shell away from the placement space. The power cord and the heat dissipation body can dissipate heat for the PiCCO capacity monitor to ensure the accuracy of the detection data.

[0003] The existing cooling and heat dissipation mechanism is not convenient for replacing the cooling fan. The cooling fan of a general cooling mechanism will be damaged after long-term use and needs to be replaced. The cooling fan is generally fixed to the monitor housing by screws. When replacing the cooling fan, tools are required to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload, reduces the maintenance efficiency, and has a poor heat dissipation effect. Generally, cooling and heat dissipation mechanisms dissipate heat through cooling fans. The heat dissipation of cooling fans is greatly affected by the ambient temperature. When the ambient temperature is high, it is difficult to quickly lower the temperature of the monitor, affecting the stability of the monitor. In order to solve the above-mentioned problems, we propose a cooling and heat dissipation mechanism for the monitor host. Utility Model Content
