Description of the Invention: [Technical Field of the Invention] The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module having a high efficiency heat pipe. [Prior Art] With the continuous improvement of industrial technology, various electronic products are developing in the direction of small size, light weight and low power consumption. Since the energy efficiency of electronic components is not 100%, many of the power is wasted and converted into heat, which causes the temperature inside the system to rise. When the temperature of the system exceeds the allowable operating temperature of the electronic component, the physical properties of the electronic component change as the ambient temperature increases, causing the system's power cycle b to malfunction, causing operational errors or terminating the function. Moreover, as the temperature in the system increases, the failure rate of the system increases. If you want to make the system more reliable, you must enable the system to maintain the proper operating temperature range. In order to enhance the divergence of electronic components: the practice of the line is mostly to use heat sinks at the heat source to heat the heat f) in a natural or forced convection manner = under the tube:, the tube can be used in a small cross-sectional area and temperature The difference between the two sources is a considerable distance, and without the need for external electrical considerations, the fistula is one of the pieces of economic use of mines and workshops.传热 The heat transfer element widely used in e-government thermal products. Please refer to Figure 1, which is a schematic diagram of the conventional heat pipe W. The teaching tube is provided with a capillary structure on the pipe wall 11 in the closed working chamber. 1307399 ^The working pipe has a working fluid. The heat pipe ι〇 is evaporated into gas by the endothermic heat: , , coffee 2 == 然; = end; : body = fine knot r capillary (10) back == then #% ‘ to achieve the effect of heat dissipation. Ji Qiu, please forgive the reference to Figure 1 and Figure 2, Figure 2 is the outline of the wide range of orders. Since the thickness of the capillary end of the conventional heat pipe is the same, the thicker the capillary structure 12 is, the higher the volume of the hair bubble can be increased, but the vapor is easily changed when the phase is changed: the width is not wide. If the capillary structure 12 is thinner, how the bubble solves the steaming lift 敫At due to the thickness of the capillary structure and effectively increases the heat exchange area of the heat pipe to achieve an overall heat dissipation performance, which is an important issue. SUMMARY OF THE INVENTION Group and ::: The problem of the present invention is proposed by the present invention - a type of heat dissipation mold W:: two problems of conventional vapor bubble blocking and can effectively 曰*,:, & And improving the overall heat dissipation performance. To achieve the above object, the present invention provides a heat pipe comprising a casing, a capillary structure and a working fluid, wherein the casing has a space of 1307399 and a bottom, and the bottom surface is facing. ~ There is a non-flat surface 'and this, while the working body "0 plant, ·, field structure is set at the bottom of the surface of the machine system is filled in the shell. According to another object of the present invention, the heat pipe and the at least one dissipating key piece of the heat dissipation module include a structure and a work surface: a; a bottom surface: f; a non-flat surface, and The table hair, the 'field,', and alpha structures are placed on the surface, and the workflow system is filled with the body. The heat sinking fins are disposed outside the heat pipe and connected to the heat pipe. 'The heat dissipation of the present invention and its heat pipe are provided, and the bottom of the casing is such that the heat dissipation between the casing and the capillary structure contributes to the improvement (4). In addition, the same as: the formation of a flat capillary structure on the surface 'has not been (and the smaller thickness part, can make the working fluid easier, the field structure evaporates and leaves the capillary The structure, in turn, avoids the problem of blockage between the bottom and the capillary, between the boiling and the vapor bubbles; in the thicker part, it can provide sufficient liquid fluid to supplement the thickness of the main. Bruises and avoids the occurrence of dryness. In addition, for the capillary structure disposed along the rim of the surface of the bottom surface of the body, the contact area between the accommodating space and the capillary structure can be increased, that is, the evaporation area is increased, and the efficiency of the heat pipe is also improved. The above and other objects, features and advantages of the present invention will become more apparent and understood. An embodiment of the heat dissipation module and heat pipe of the present invention. 3A and 3B, FIG. 3A is a schematic view of a heat pipe according to a preferred embodiment of the present invention, and FIG. 3B is a schematic view of a broken line portion D of FIG. 3A. The heat pipe 20 of the present invention is exemplified by a flat heat pipe, including A housing 21, a capillary structure 22 and a working fluid w. The housing 2 is equipped with a housing space 211 and a bottom portion 212. In the present embodiment, the housing 21 of the second to flat shape is taken as an example. The material of the casing 21 is a high thermal conductive material, such as copper, silver, aluminum or an alloy thereof. When the bottom 212 of the casing 21 is in contact with a heat source (not shown), the heat source and the heat can be quickly transferred to He is at the office. The accommodating space 211 is a closed space/the bottom portion 212 has a surface 213' and the surface 213 faces the accommodating space 211. The bottom portion 212 has a surface 213 that is a non-flat surface, that is, the bottom portion 212 has a different thickness. The surface 213 is formed with at least one bump 214, and the plurality of bumps 214 are formed on the surface 213 to form a checkerboard pattern, a pattern in a r〇w pattern, a symmetrical pattern or an asymmetric pattern. In Fig. 3B, the surface 213 is a checkerboard pattern formed by a plurality of square-shaped bumps 214, and the surface 213 has a square or rectangular cross-sectional shape. The capillary structure 22 is disposed on the surface 213 of the bottom portion 212. Taking FIG. 3B as an example, the capillary structure 22 is laid on the surface 213 of the bottom portion 212, so that the capillary structure 22 faces the accommodating space 211 to form a plane, that is, the thickness of the bottom portion 212 of the casing 21 and the capillary structure 22 and For the same. As such, the capillary structure 22 has a first thickness H1 and a second thickness H2 in a direction perpendicular to the bottom portion 212, wherein the first thickness H1 is greater than the second thickness H2. Here, it is necessary to specify that the design of 1307399 = = = 2 referred to here is for the evaporation end A. The material of π wt and Taguchi 22 includes materials selected from plastics, metals, and materials. The group refers to the scale of the towel, and the method of the capillary 13 is selected from the group consisting of sintering, filling, filling, self-sintering, adhesion, filling, and the shape of the + ^ 苒 ^ - or a combination thereof. The group consisting of true charge and sedimentation is filled with a working fluid W in the casing 21, such as an inorganic compound, pure water, an alcohol, a hydrazine, a liquid gold, an organic compound or a mixture thereof. When 埶': 令,, near the end of the heat source (ie, the base, / / 0 is placed on the heat source, the fluid absorbs the structure of the heat generated by the heat source = works away from the heat source - end (ie, the condensation end B) =2;=Dive: Afterwards, it is converted into a liquid working fluid, and then flows back to the evaporation end A by the capillary t capillary force, so that it is cooled away from the heat source to achieve the heat dissipation effect. Since the bottom portion 212 of the casing 2i has an uneven contact surface between the casing 21 and the capillary structure 22, the heat dissipation performance of the heat pipe 20 is improved. Further, the: σ contributes to different thicknesses, and the thickness is small. It can make the working fluid easier to get from the capillary structure, and thus avoid the blocking problem caused by the bottom 2 bristles and the detachment of the capillary bubbles. On the other hand, the Fteng and steamed parts of the 22-section (ie, without the bumps 214) = the H1 working steam with a large degree, the αS r shell 1 can supply enough liquid 9 1307399 However, the present invention The hair is not limited to this, and the capillary is on the surface 213 of the bottom portion 212, and the structure = 22 is formed by a two-fibrous structure except for the laying of the two U-U; and the setting of the capillary structure 22 is as follows: 3: That is, the capillary structure 22 has a phase on the surface 213, for example, as shown in Figs. 4 and 5, and is located at the bumps 214, Η2. Thick production Η1, Η9, ... structure 22, the thickness and the required degree Η2 can be equal or unequal, the end use is due to the capillary structure 22 (four) surface 213: the wheel corridor, so that the increase can be accommodated Space and capillary knot: product] increases the evaporation area) 'Help: 2 In addition, the same, 'bottom 212, surface 213, system 4 = cylinder sister: can make the contact between the shell and the capillary structure The area is increased, so the heat dissipation performance of the monthly heat pipe.
