Portable computers are widely used in the industrial field due to their small size and portability. Because the portable computer applied to the industrial field is often high in operating power, and the heating device in the portable computer can generate a large amount of heat, the portable computer needs to be cooled, and the heating device is prevented from being out of work due to overhigh temperature. Because the environment of the industrial application scene is often severe, the portable computer needs to have the performances of water resistance, dust resistance and the like, and the shell of the portable computer is usually designed in a sealing manner, so that the heat generated inside the portable computer is not easy to dissipate to the outside of the shell. At present, a fan is usually arranged in a portable computer for heat dissipation, and the fan generally needs to occupy a larger space, so that the volume of the portable computer is too large, and the requirements of the portable computer on small size and portability cannot be met.

In order to solve the above problems, the inventors of the present application have found that heat generated from the internal devices of the portable computer can be dissipated by heat conduction. For example, a heat conductive member attached to a heat generating device is provided in a portable computer, and the heat conductive member is attached to a rear case of the portable computer, so that the heat generated by the heat generating device in the portable computer is conducted to the rear case by the heat conductive member and is dissipated to the ambient environment through the rear case, thereby achieving heat dissipation. Since the heat-conducting member requires less space than the fan, the portable computer can be made small in size for portability.

In order to further improve the heat dissipation performance of the portable computer, the inventor further finds that a heat dissipation fin set may be further disposed on the outer surface of the rear case, so as to increase the heat dissipation area of the outer surface of the rear case, and further, the heat conducted to the rear case is rapidly exchanged with the ambient air through the outer surface of the rear case, thereby improving the heat dissipation efficiency.

In the prior art, a protruding arrangement is usually adopted when a heat dissipation fin group is arranged on a device, that is, the heat dissipation fin group integrally protrudes from the outer surface of the device on which the heat dissipation fin group is arranged. Although the method can achieve a better heat dissipation effect, for a small-sized portable computer, the heat dissipation fin set protrudes out of the outer surface of the portable computer, which increases the thickness of the portable computer, and causes the portable computer to be inconvenient to carry. Therefore, in the embodiment of the application, the heat dissipation fin group does not protrude out of the outer surface of the rear shell, and on the basis of increasing the heat dissipation area of the rear shell and improving the heat dissipation efficiency, the thickness of the rear shell is not required to be increased, so that the thickness of the whole portable computer is thin, the small-size requirement of the portable computer is met, and the portable computer is convenient to carry.

In addition, portable computers are generally held by a user and have certain requirements on the comfort of the hand. Because the radiating fin group does not protrude out of the outer surface of the rear shell, the hand feeling is comfortable when a user touches the portable computer.

Furthermore, because the rear shell is provided with the radiating fin group which does not protrude out of the outer surface of the rear shell, and a part of hollow structure is formed at the position of the rear shell where the radiating fin group is arranged, the strength of the rear shell may be reduced. Due to the mobile use mode, the portable computer generally has certain requirements on the structural strength and needs to meet the requirements of falling resistance (fall resistance). In order to ensure the strength of the rear shell, the inventor finds that the strength of the rear shell is ensured and the requirement of falling resistance (falling resistance) is met by arranging the radiating fin group in the middle area of the outer surface of the rear shell and arranging a distance between the outer edge of the radiating fin group and the outer edge of the rear shell.

Other components such as a battery 221 are also provided in the housing space 130. The devices that generate heat, such as the CPU and the battery 221, are the heat generating devices 141. The heat generating device 141 may be fixed on the front case 110.

The heat conductive member 150 may be disposed at a position opposite to the heat generating device 141 on the inner surface of the rear case 120, that is, positions of the heat conductive member 150 and the heat generating device 141 in the first direction a perpendicular to the rear case 120 substantially correspond. The heat conductive member 150 is attached to the heat generating device 141 at one side and the rear case 120 at the other side, so that the heat conductive member 150 conducts heat generated from the heat generating device 141 to the rear case 120 from the heat generating device 141.

The heat sink fin set 160 may be integrally formed with the rear case 120. Or a groove may be formed in the middle region of the rear shell 120, the plurality of heat dissipation fins 162 are fixed in the groove in a sticking manner, and a distance is reserved between adjacent heat dissipation fins 162 to form the heat dissipation fin group 160.

It is understood that the outer edge 161 of the heat dissipating fin set may have a distance d1 from the outer edge 122 of the rear housing only along the second direction b, or the outer edge 161 of the heat dissipating fin set may have a distance d2 from the outer edge 122 of the rear housing only along the direction perpendicular to the second direction b, which is not limited in the present application.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating a relationship between a projection of a heat-dissipating fin set and a projection of a heat-conducting member along a direction perpendicular to a rear case according to an embodiment of the present application, where the projection 160a of the heat-dissipating fin set and the projection 150a of the heat-conducting member are completely overlapped. Referring to fig. 6, fig. 6 is a schematic view illustrating a relationship between a projection of a heat-dissipating fin set and a projection of a heat-conducting member along a direction perpendicular to a rear case according to another embodiment of the present application, where the projection 160a of the heat-dissipating fin set may partially coincide with the projection 150a of the heat-conducting member.

Referring to fig. 2 and 3, that is, the heat conducting member 150 and the heat dissipating fin set 160 are disposed at corresponding positions on two sides of the rear case 120, so that the rear case 120 can rapidly conduct heat on the heat conducting member 150 to the heat dissipating fin set 160, the heat is dissipated to the surrounding air through the heat dissipating fin set 160 under the action of air convection, and the heat can also be radiated to the surrounding air through the heat dissipating fin set 160, so that the temperatures of the rear case 120, the heat conducting member 150, and the heat generating device 141 are rapidly decreased.

Referring to fig. 4, the fact that the heat dissipating fin set 160 does not protrude from the outer surface 121 of the rear housing means that the heat dissipating fin set 160 may be flush with the outer surface 121 of the rear housing, a portion of the heat dissipating fin set 160 may be flush with the outer surface 121 of the rear housing, another portion of the heat dissipating fin set is lower than the outer surface 121 of the rear housing, and the heat dissipating fin set 160 may be entirely lower than the outer surface 121 of the rear housing.

The heat dissipation fin set 160 is disposed on the outer surface 121 of the rear housing, and the projection 160a of the heat dissipation fin set along the direction perpendicular to the rear housing 120 at least covers a part of the projection 150a of the heat conducting member, so that the heat dissipation area of the outer surface 121 of the rear housing is increased, the heat conducted by the heat dissipation fin set 160 to the rear housing 120 can be rapidly exchanged with the surrounding air, and the heat dissipation efficiency is improved. Since the heat conductive member 150 requires less space than a fan, the portable computer 100 can be made small in size and portable. Further, the heat dissipating fin set 160 is not protruded from the outer surface 121 of the rear case, and the thickness of the rear case 120 is not increased, so that the thickness of the rear case 120 is thin, and thus the thickness of the entire portable computer 100 is small, the small-size requirement of the portable computer 100 is satisfied, and the portable computer is convenient to carry. The portable computer 100 of the present application has both a small size and good heat dissipation properties.

In addition, the heat dissipating fin set 160 is not protruded from the outer surface 121 of the rear case, so that the user feels comfortable when touching the portable computer 100. In addition, the heat dissipation fin set 160 is disposed in the middle region of the outer surface 121 of the rear shell, and a distance is formed between the outer edge 161 of the heat dissipation fin set and the outer edge 122 of the rear shell, so that the heat dissipation fin set 160 does not occupy the whole region of the rear shell 120, and the original thickness of the rear shell 120 can be reserved in other regions of the rear shell 120 where the heat dissipation fin set 160 is not disposed, thereby ensuring the strength of the rear shell 120 and meeting the requirement of drop resistance (drop resistance).

Referring again to fig. 4, in an alternative embodiment, the heat sink fin set 160 includes a plurality of heat sink fins 162, the heat sink fins 162 are elongated, and each heat sink fin 162 extends toward the outer edge 122 of the rear housing.

Each of the heat dissipation fins 162 extends along the second direction b toward the outer edge of the rear housing 120 in fig. 4, and is in an elongated shape, and compared with the manner in which a plurality of heat dissipation fins 162 with shorter lengths are disposed on the same extension line, the manner in which the entire heat dissipation fin 162 extends along the second direction b toward the outer edge 122 of the rear housing can enhance the strength of the middle area of the rear housing 120, and improve the drop resistance (drop resistance).

While the radiator fins extend in the transverse direction in fig. 4, it is understood that in some embodiments, the radiator fins 162 may also extend in the longitudinal direction, i.e., in the direction perpendicular to the second direction b in the plane shown in fig. 4, which also belongs to the direction toward the outer edge of the rear housing 120, or extend in an oblique direction (e.g., the diagonal direction of the four corners of the rear housing 120), which is not limited in this application. In addition, the overall shape of the heat dissipating fin set 160 may be set according to the shape and position of other components on the rear housing 120, for example, in fig. 4, the hand rest 124 is disposed on the rear housing 120, so as not to interfere with the hand rest 124 on the basis of ensuring the heat dissipating area of the heat dissipating fin set 160, in this embodiment, the overall shape of the heat dissipating fin set 160 is set to be the butterfly shape shown in fig. 4, the protruding portions from the upper and lower positions toward the two sides may ensure the heat dissipating area of the heat dissipating fin set 160, and the recessed portions at the two sides in the middle may avoid interference with the hand rest 124.

By providing the heat sink fins 162 as elongated strips, each heat sink fin 162 extends in a direction toward the outer edge 122 of the rear housing, the strength of the middle region of the rear housing 120 is enhanced, and the drop resistance (fall resistance) is improved.

Referring to fig. 3 again, in an alternative embodiment, the heat conducting member 150 includes a heat conducting block 151 and a heat conducting pipe 152 contacting with the heat conducting block 151, two surfaces of the heat conducting block 151 facing away from each other are respectively attached to the heat generating device 141 and the rear case 120, and the heat conducting pipe 152 is attached to the rear case 120.

The heat conduction block 151 can be made of aluminum materials, so that the weight is reduced. The heat conduction block 151 may be attached to a device having a large heat generation amount in the heat generating device 141, so that the heat conduction block 151 may rapidly conduct heat of the device having a large heat generation amount to the rear case 120, thereby rapidly reducing the temperature of the device. The rear case 120 may be made of magnesium alloy, so that the heat conducted from the heat conduction block 151 to the rear case 120 is quickly conducted to the ambient air.

The heat pipe 152 may be made of copper, which has a thermal conductivity much higher than that of aluminum, so that the efficiency of the heat pipe 152 in transferring heat to the rear case 120 is improved. The heat conductive pipes 152 are in contact with the heat conductive block 151, which means that the heat conductive pipes 152 are in contact with the outer surface of the heat conductive block 151 or in contact with the inner surface of the heat conductive block 151. For example, the heat conduction pipe 152 is attached to a side surface of the heat conduction block 151, or a hole/groove for passing the heat conduction pipe 152 is formed in the heat conduction block 151, and the heat conduction pipe 152 passes through the hole/groove and contacts with an inner wall of the hole/groove, so that heat of the heat conduction block 151 can be conducted to the heat conduction pipe 152. The heat pipe 152 is attached to the rear case 120, so that a heat conduction area between the heat conducting member 150 and the rear case 120 can be increased, thereby improving heat conduction efficiency. Fig. 3 shows that a groove is formed on one surface of the heat conduction block 151, which is attached to the rear case 120, and the heat conduction pipe 152 is inserted into the groove, and three surfaces of the section in which the heat conduction pipe 152 is inserted into the groove are attached to the heat conduction block 151 in the groove, and the other surface is attached to the rear case 120. The remaining sections of the heat conductive pipes 152 are located outside the heat conductive blocks 151 and attached to the rear case 120, increasing the heat conductive area.

The two sides deviated from the heat conducting block 151 are respectively attached to the heating device 141 and the rear shell 120, so that the heat of the heating device 141 is conducted to the side deviated from the heat conducting block 151 (the side attached to the heating device 141) from one side of the heat conducting block 151 (the side attached to the rear shell 120), the heat conducting pipe 152 is contacted with the heat conducting block 151, part of heat on the heat conducting block 151 is conducted to the heat conducting pipe 152, and the heat conducting pipe 152 is attached to the rear shell 120, so that the heat conducting area between the heat conducting block 150 and the rear shell 120 is increased, and the heat radiating efficiency is improved. In addition, the heat conductive member 150 is reduced in weight by providing the heat conductive pipe 152 to increase a heat conductive area between the heat conductive member 150 and the rear case 120 and improve heat conductive efficiency, so that the portable computer 100 is more portable.

The portable computer 100 has high requirements for water and dust resistance (IP). The embodiment of the application further provides a waterproof and dustproof structural design. Referring to fig. 2, 3 and 8, fig. 8 is a schematic diagram illustrating an internal structure of the front shell 110 according to an embodiment of the present disclosure, in an alternative embodiment, the front shell 110 includes a front plate 111 and a side plate 112 surrounding an outer edge 1111 of the front shell and connected to the front plate 111, a surface 1121 of the side plate facing the rear shell surrounds a periphery of the side plate 112 and is provided with an annular groove 11211, and an annular sealing ring 170 is embedded in the annular groove 11211. The inner surface 123 of the rear housing is provided with an annular boss 1231 around the periphery of the rear housing 120. The rear housing 120 is fixedly connected to the front housing 110, the annular protrusion 1231 is embedded into the annular groove 11211 and presses the annular sealing ring 170, and the annular sealing ring 170 is tightly attached to the annular groove 11211 and the annular protrusion 1231.

Referring to fig. 9 and 10, fig. 9 showsbase:Sub>A schematic sectional view taken alongbase:Sub>A directionbase:Sub>A-base:Sub>A in fig. 1, fig. 10 shows an enlarged schematic view ofbase:Sub>A portionbase:Sub>A in fig. 9, and the periphery of the rear case 120 and the periphery of the front case 110 are fixed by screws, so that the annular protrusion 1231 is inserted into the annular groove 11211 and presses the annular sealing ring 170, and the annular sealing ring 170 is tightly fitted inbase:Sub>A space between the annular groove 11211 and the annular protrusion 1231.

By fixedly connecting the rear shell 120 with the front shell 110 and embedding the annular protrusion 1231 into the annular groove 11211, the annular protrusion 1231 on the periphery of the rear shell 120 presses the annular sealing ring 170 in the annular groove 11211 on the side plate 112, so that the annular sealing ring 170 is tightly attached to the annular groove 11211 and the annular protrusion 1231, and the waterproof effect between the front shell 110 and the rear shell 120 is improved. When external water is sprayed to the front case 110 and the rear case 120, the water is not easily introduced into the receiving space 130 from the gap between the front case 110 and the rear case 120.

Referring to fig. 8 and 10 again, in an alternative embodiment, one surface 1121 of the side plate facing the rear case has a step 1122, the step 1122 includes a first step surface and a second step surface 11222 facing the rear case 120 and parallel to each other, the first step surface 11221 protrudes from the second step surface 11222, the first step surface 11221 is located at an outer edge of the rear case 120, and the rear case 120 is fixed on the second step surface 11222.

By providing the step portion 1122 on the side plate facing the one surface 1121 of the rear case and providing the first step surface 11221 in the step portion 1122 to protrude from the second step surface 11222, the first step surface 11221 is located at the outer edge of the rear case 120, and the rear case 120 is fixed to the second step surface 11222, so that when water is sprayed from the front case 110 to the rear case 120, water does not easily enter the gap between the front case 110 and the rear case 120, and water needs to pass through the distance from the first step surface 11221 to the second step surface 11222 to enter the annular protrusion 1231 and the annular recess 11211 from the gap between the front case 110 and the rear case 120, so that a good waterproof effect is provided between the front case 110 and the rear case 120.

Referring to fig. 8 again, in an alternative embodiment, the annular groove 11211 is disposed proximate to the outer edge 1123 of the side plate, the side plate 112 has a plurality of mounting holes 1124 formed therein, and the annular groove 11211 near the mounting holes 1124 bypasses the mounting holes 1124 from a side of the mounting holes 1124 facing the accommodating space 130.

By bringing the annular groove 11211 close to the outer edge 1123 of the side plate, the waterproof effect between the position on the side plate 112 close to the outer edge and the rear case 120 is good, and by bypassing the annular groove 11211 near the mounting hole 1124 around the mounting hole 1124 from the side of the mounting hole 1124 toward the accommodating space 130 rather than around the mounting hole 1124 from the side of the mounting hole 1124 toward the outside of the portable computer 100, that is, by providing a seal prevention measure at the side of the mounting hole 1124 toward the accommodating space 130, it is possible to prevent water from entering the accommodating space 130 from the mounting hole 1124, and a good waterproof effect is achieved.

Specifically, with continued reference to fig. 11 and 12, the second fixing portion 1822 may be adhered to the inner surface 114 of the front housing by glue, so as to achieve a seal between the second fixing portion 1822 and the inner surface 114 of the front housing. A sealing ring may be sleeved between the second fixing portion 1822 and the inner surface 114 of the front housing, so that the sealing ring is tightly attached to the second fixing portion 1822 and the inner surface 114 of the front housing, and the second fixing portion 1822 and the front housing 110 are fixed, so that when the key 181 is pressed, the second fixing portion 1822 and the inner surface 114 of the front housing maintain a seal, thereby preventing water from entering the portable computer 100 from the opening 113 and ensuring its protective performance.

A cavity 184 is formed between the inclined portion 1823 of the ring-shaped elastic member 182 and the cylinder 1812 of the key 181, so that when the force application portion 1811 is pressed down, the inclined portion 1823 is easily deformed toward the cavity 184, and the cylinder 1812 can rapidly trigger the switch assembly 190 to open, thereby improving the hand feeling when the key assembly 180 is pressed down. By fixing the first fixing portion 1821 of the annular elastic member 182 in the annular gap 183 between the annular limiting portion 1813 and the cylinder 1812, when the inclined portion 1823 deforms, the first fixing portion 1821 can also be stably fixed to the inner wall 1831 of the annular gap, so as to enhance the waterproof effect between the inner wall 1831 of the annular gap and the first fixing portion 1821.
