Description

A notebook computer without cooling vents

technical field

The present invention relates to computers, in particular to notebook computers.

Background technique

Most notebook computers on the market rely on traditional fans for heat dissipation. There is a cooling vent on the side of the host. The setting of the cooling vent greatly reduces the overall strength of the notebook computer, and dust is easy to enter through the cooling vent. It directly affects the portability and service life of the notebook computer.

Contents of the invention

The object of the present invention is to provide a notebook computer without heat dissipation vents, so as to solve the above-mentioned technical problems.

The technical problem solved by the present invention can adopt following technical scheme to realize:

A notebook computer without cooling vents, comprising a computer main body, said computer main body including a display, a mainframe, and a casing, characterized in that said mainframe casing has no vents, said mainframe is provided with a mainboard, and said mainboard is provided with a CPU The CPU module conducts the heat generated during operation to the heat dissipation mechanism connected with the outside through a heat conduction mechanism, and dissipates the heat through the heat dissipation mechanism. The host conducts heat outward through the heat dissipation mechanism, so that the shell does not need ventilation holes, which increases the strength of the shell of the host, and at the same time, dust will not enter the shell through the vents, which can adapt to a dusty environment.

The host adopts a fanless host, and the heat conduction mechanism includes an upper heat sink and a lower heat sink, and the upper heat sink and the lower heat sink are slidably plugged in; the lower heat sink is connected to For the CPU module, the upper heat sink is connected to the heat dissipation mechanism. The lower heat sink can be directly connected to the CPU module, or can be connected to the CPU module through a heat-conducting material. The host structure is preferably a fanless host structure, which can reduce heat convection in the housing and effectively prevent external dust from entering the housing. Mainframes with fanless structure are mostly used on tablet PCs, which limit the selection of CPU modules. Most technicians in the field believe that notebook computers handle a relatively large amount of content and the operating speed of the CPU module is relatively high, so the mainframe Generally do not use the mainframe without fan structure. However, when a notebook computer does not play large-scale games, the operating speed of the CPU module is not high, and due to the controllability and operability of the notebook computer, ordinary users will not use the notebook computer to play games continuously for a long time. The modules are not always operating at high speed, so the present invention can adopt a host without a fan structure.

The main engine adopts a main engine with a fan structure, and the main body of the computer also includes a fan. The heat conduction mechanism includes an upper cooling fin and a lower cooling fin, and the slidable insertion between the upper cooling fin and the lower cooling fin The lower heat sink is located in the air supply direction of the fan, the CPU module conducts heat to the lower heat sink through the fan, and the upper heat sink is connected to the heat dissipation mechanism. Thermal convection is formed in the housing, and the heat is dissipated by the convective air. Moreover, the way of heat convection can alleviate the situation that the heat conduction mechanism cannot quickly conduct heat to the heat dissipation mechanism, effectively avoiding excessive local heat. Of course, for laptops, even if the heat does not dissipate quickly, it will not affect the use. The fan is provided with an air inlet pipe and an air outlet pipe, the air inlet pipe is far away from the CPU module, and the air outlet pipe faces the CPU module. The design of the air inlet and outlet ducts can effectively control the direction of heat convection, so that the cold air away from the CPU module can be effectively blown to the CPU module.

The slidable insertion between the upper heat sink and the lower heat sink can effectively reduce the impact of external equipment on the heat conduction mechanism, thereby reducing the impact on the CPU module. The invention adopts the heat conduction mechanism with impact resistance, effectively reduces the damage to the CPU module by external equipment, and can well protect the CPU module.

The upper heat sink and the lower heat sink are not fully fit and plugged in, so that there is room for buffering the cooling teeth between the upper heat sink and the lower heat sink.

Thermal conductive silica gel is filled between the upper heat sink and the shell. Thermally conductive silica gel is a material used to fill the gap between the heat conduction mechanism and the shell, and its function is to conduct the heat emitted by the heat conduction mechanism to the shell.

The bottom of the lower cooling fin is fixed on the main board by screws. Easy to disassemble and maintain.

The top of the upper cooling fin is fixed on the casing by screws; the sides and middle of the top cooling fin are fixed on the casing by screws. Since the shell is usually made thinner, multiple screws are used to fix the heat conduction mechanism, which can better fix the heat conduction mechanism.
