Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 2, the cooling system for notebook computer that the utility model provides, comprises at least one group of heat pipe heat radiation module for being connected with the mainboard of notebook computer; Heat pipe heat radiation module comprises the first conducting strip 4, heat pipe 5 and the second conducting strip 6; The second conducting strip 6 is connected with the first conducting strip 4 by heat pipe 5.

Preferably, comprising a heat pipe 5 in heat pipe heat radiation module, can certainly be other quantity; When heat pipe heat radiation module comprises more than two and two heat pipe 5, interval is parallel is respectively arranged between the first conducting strip 4 and the second conducting strip 6 for each heat pipe 5, and the evaporator section of heat pipe 5 is all connected with the first conducting strip 4, and condensation segment is all connected with the second conducting strip 6.

As shown in Figure 1, the notebook computer that the utility model provides, comprise the drain pan 1 with spatial accommodation, mainboard 2 and keyboard holder 3 are installed in spatial accommodation, also comprise the temperature-uniforming plate (not shown) being arranged in drain pan 1 and at least one group of heat pipe heat radiation module being connected with mainboard 2.Temperature-uniforming plate is made by uniform temperature material (as graphite etc.), be positioned at mainboard 2 belows, and tiling is pasted on notebook computer drain pan 1 inwall.Heat pipe heat radiation module comprises the first conducting strip 4, heat pipe 5 and the second conducting strip 6.The first conducting strip 4 covers on main board for notebook computer 2, and fixes by modes such as screw or welding; The second conducting strip 6 is connected with the first conducting strip 4 by heat pipe 5, and heat pipe 5 evaporator sections are connected with the first conducting strip 4, and heat pipe 5 condensation segments are connected with the second conducting strip 6, and the second conducting strip 6 is fixed on keyboard holder 3.In order to shorten heat-dissipating distance between the first conducting strip 4 and mainboard 2 and the heat-dissipating distance between the second conducting strip 6 and keyboard holder 3, between the first conducting strip 4 and mainboard 2, be filled with the first heat-conducting medium 7, between the second conducting strip 6 and keyboard holder 3, being filled with the second heat-conducting medium 8, the first heat-conducting mediums 7 and the second heat-conducting medium 8 all fixes by the mode of hot melt.

The first conducting strip 4 and the second conducting strip 6 are metal material, preferably, are the stronger aluminium flake of heat conductivility or copper sheet; The first heat-conducting medium 7 and the second heat-conducting medium 8 are thermal conductivity better and have flexible nonmetallic heat conductive material, comprise heat-conducting silicone grease, heat conductive silica gel, Graphite pad etc., there are good heat conduction and insulating property, for strengthening the heat conductivility of heat radiation module, fill up the gap between device, reduce thermal resistance, have buffering shockproof properties concurrently, alleviate the frictionally damage between device.

When notebook computer moves, the heat that mainboard 2 produces is passed to the first conducting strip 4 through the first heat-conducting medium 7 by heat, the evaporator section that is reached heat pipe 5 by the first conducting strip 4 is absorbed, then the condensation segment at heat pipe 5 carries out condensation heat release, by the second conducting strip 6, heat is passed to the second heat-conducting medium 8, and then is passed to keyboard holder 3, because keyboard holder 3 is the good hardware of thermal conductivity, and near notebook drain pan, thereby heat is passed.In addition, the temperature-uniforming plate of mainboard 2 belows makes heat tile and spread out effectively and uniformly, and by natural convection and the heat loss through radiation of computer bottom surface, effectively heat is discharged, and further strengthens heat radiation.Because heat pipe heat radiation module extends and arranges along drain pan 1 sidewall direction, and run through drain pan, effectively utilize the heat-dissipating space in drain pan, like this, the heat that mainboard 2 produces can be dispelled the heat by the heat radiation module of mainboard 2 tops and the temperature-uniforming plate of below simultaneously, the useful area that makes to dispel the heat maximizes, and all thermal effect is preferably changed; In practice, can many group heat pipe heat radiation modules be set according to the performance of notebook computer.

In sum, the utility model is by being distributed in temperature-uniforming plate and the heat pipe heat radiation module in drain pan, and utilize metal, the heat conductivility that heat-conducting medium and heat pipe are good, effectively utilize the heat-dissipating space of notebook computer, the spread heat that notebook computer is produced comes, avoid heat to concentrate on mainboard region, affect the performance of notebook computer, due to heat pipe heat radiation module and temperature-uniforming plate thickness less, so even slim notebook computer is suitable for this cooling system too, not only there is good radiating effect, guaranteed the high performance requirements of notebook computer, Fanless radiation structure can effectively reduce system noise again simultaneously, reduce power consumption, more meet the requirement of user to notebook.In addition, this cooling system can be suitable for desktop computer equally.
