Example 1

As shown in fig. 1, the present application provides a heat dissipation structure for a notebook LCD, which is applied to a first device including a first housing 1 and a second housing 2, wherein the structure includes: the first end of the conductive module 3 is connected with the LCD light bar 4, and the LCD light bar 4 is arranged in the accommodating space of the first shell 1; the heat dissipation module 5 is arranged in the accommodating space of the second shell 2, the heat dissipation module 5 is arranged at one side close to the conduction module 3, and the heat dissipation module 5 can perform heat dissipation treatment on the conduction module 3.

In particular, a notebook computer (Laptop), which is called a notebook for short, also called a portable computer, a Laptop computer, a palmtop computer or a Laptop computer, is characterized by a small body. Compared with a desktop computer, the portable personal computer is small and convenient to carry, the shell is attractive, the protective effect on internal devices is achieved for the desktop computer, the first shell 1 is an external wrapping shell of a Liquid Crystal Display (LCD) of a notebook computer, the second shell 2 is an external wrapping shell of a plane where a keyboard connected with the LCD is located, the shell material is different based on different appearance designs, practical designs and main performances of the notebook computer, and therefore the portable personal computer plays a role in protecting the components arranged in the containing space. Further, the conduction module 3 is mainly built into the rotating shaft by adding cooling fins at the position of the notebook LCD light bar. Improve LCD luminance and realize through increasing LED lamp pearl quantity, under the maximum brightness of the LCD of present 15 cun, lamp strip consumption can be about 15w, and calorific capacity is very big, consequently need with the thermal module 5 that corresponds with LCD lamp strip 4 carries out the heat dissipation assembly that corresponds, and then can conduct the heat that the LCD lamp strip produced through conduction module 3, carries out the thermal treatment for the heat of the LCD lamp strip 4 that corresponds thermal module 5 that sets up with the conduction to reach corresponding radiating effect.

Further, the heat dissipation module 5 further includes: a heat dissipation fan 51, wherein the heat dissipation fan 51 is arranged in the accommodating space of the second housing 2; the ventilation structure 52 is disposed between the heat dissipation fan 51 and the conduction module 3, and the ventilation structure 52 can conduct the heat dissipation wind generated by the heat dissipation fan 51 to the conduction module 3 to perform heat dissipation processing on the conduction module 3.

Further, the ventilation structure 52 includes at least one ventilation opening.

Specifically, the heat dissipation fan 51 dissipates heat in a forced thermal convection manner, and by virtue of a flow guiding effect thereof, the heat dissipation effect is achieved by enabling air to dissipate heat in a certain manner through a "forced convection" manner, and the heat dissipation fan 51 is disposed in the accommodating space of the second housing 2, and is generally adjacent to the memory bank of the notebook. The ventilation structure 52 is a ventilation panel for installing the cooling fan 51, a gap between the cooling fan 51 and the ventilation structure 52 is as small as possible so as to avoid affecting the cooling effect of the cooling structure, the installation aperture of the fan is larger than the aperture of the fan, the ventilation opening in the ventilation structure 52 is at least one ventilation opening, the geometric shape of the ventilation opening is not specifically limited, and the ventilation opening can be correspondingly adjusted based on specific performance requirements, so that the heat dissipation effect can be conveniently achieved through the transmission of air flow. Because the heat dissipation process of the notebook computer is the automatic heat dissipation realized based on the specific situation, when the heat conducted by the conduction module 3 is detected to reach a certain heat standard, the heat dissipation module 5 completes the automatic heat dissipation, namely, the heat dissipation process is completed in a convection mode between the heat dissipation fan 51 and the ventilation structure 52, the heat generated due to the increase of the number of the lamp beads in the LCD lamp strip 4 is reduced, and the technical effect of reducing the temperature gathering at the LCD lamp strip is achieved.

Further, at least one heat dissipation fan 51 is provided.

Further, the number of the conduction modules 3 is the same as that of the heat dissipation modules 5.

Specifically, as shown in fig. 1, two specific examples of the heat dissipation fans are provided for the heat dissipation module; the single fan system can be designed by the structural design of the connector 6 and the fan outlet. However, in order to ensure the effectiveness of the heat dissipation function, the number of the conduction modules 3 and the number of the heat dissipation modules 5 need to be kept consistent. Specifically, the specific working principle of the cooling fan 51 is to push air in the vertical direction, so as to accelerate the heat loss of the cooling fins at the bottom of the cooling fan, and structurally, the cooling fan can be mainly in a turbine structure, the fan blades are vertically and annularly arranged with the rotating surface, in the working process, the air enters the space surrounded by the annular fan blades from the axial direction, and then is transversely thrown out by the centrifugal effect driven by the rotation of the fan blades, a vortex-shaped scattering air flow is formed at the periphery of the fan blades, and the air is blown out tangentially from the air grid opening under the flow guiding effect of the flow channel. Further, to radiator fan 51, the size is big more, the amount of wind is also big more under the prerequisite of the same rotational speed, when other parameters are definite, its amount of wind, noise and radiating efficiency just will be by blade quantity, material and bionical design decision, because radiator fan can compensate heat pipe self heat conduction and radiating efficiency's not enough at to a great extent, consequently do not specifically limit to radiator fan's size and specification, thereby reached the gathering that reduces LCD lamp strip department temperature, improve radiator fan performance, improve LCD lamp strip radiating effect's technological effect.
