Detailed Description

The application provides an electronic equipment, it is when improving the radiating effect to internal components, has avoided the volume of equipment to become too big, therefore is favorable to the frivolous design of product.

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1 to 4, an electronic device provided in the embodiment of the present application may be a mobile phone, a tablet computer, a notebook computer, or an electronic book, and the electronic device is embodied in the drawings by taking the mobile phone as an example. This electronic equipment includes shell 1, centrifugal fan 2 and temperature-uniforming plate 3, wherein, be provided with two air outlets 11 in the shell 1 framework, air outlet 11 is two promptly, temperature-uniforming plate 3 has relative first face and second face, the first face sets up towards the back of the display screen (not shown in the figure) on shell 1, centrifugal fan 2 sets up in the second face, centrifugal fan 2's axis is perpendicular with the second face, centrifugal fan 2 sets up to two with air outlet 11 correspondingly, adopt two centrifugal fan designs, the size of two fans can be the same or not the same, for example, the small fan reduces according to the proportion of big fan, also can adopt the same, similar or different shape, in addition, shell 1 sets up corresponding air intake 12 in the position that corresponds every centrifugal fan 2, temperature-uniforming plate 3 and centrifugal fan 2 dispel the heat for the target components and parts in shell 1 together, the target components and parts can be the components and parts that can produce the heat when working such as the chip, it is easy to understand that, the concrete position of temperature-uniforming plate 3 in shell 1 should be according to the position of target components and centrifugal fan 2 can carry out the heat dissipation.

The working principle of the temperature-equalizing plate is similar to that of a heat pipe, in short, cooling liquid in an inner cavity of the temperature-equalizing plate is continuously switched and flows between liquid and gas to form a circulating heat-radiating system. Taking the case that the target component is a chip as an example, the heat generated during the operation of the chip is transferred to the evaporation end of the vapor chamber 3, the cooling liquid at the evaporation end can rapidly absorb the heat and generate vaporization to become steam, the steam rapidly expands due to the heat absorption and flows from the evaporation end to the condensation end of the vapor chamber 3, the steam contacts the inner wall with lower temperature in the flowing process and is rapidly condensed and releases the heat to liquefy to liquid, and the liquid returns to the evaporation end under the capillary action of the inner wall of the cavity. Since the centrifugal fan 2 is disposed on the second surface of the temperature-uniforming plate 3, the centrifugal fan 2 can rapidly discharge the heat dissipated by the temperature-uniforming plate 3 through the air outlet 11. This application utilizes the air intake 12 that corresponds centrifugal fan 2 setting on the shell 1 to increase the amount of wind to adopt the design of two centrifugal fan 2 and two air outlets 11, improved heat exhaust's efficiency. Meanwhile, the axis of the centrifugal fan 2 is perpendicular to the second surface of the temperature equalizing plate 3, so that the overall arrangement structure of parts is compact, and the problem that the volume of the electronic equipment is overlarge is avoided. To sum up, the electronic equipment provided by the application avoids the volume of the equipment from becoming too large while improving the heat dissipation effect on internal components, thereby being beneficial to the light and thin design of products.

When the target component is a chip, the chip may be directly connected to the temperature-uniforming plate 3, for example, the chip is disposed on the first surface of the temperature-uniforming plate 3, and the powerful heat dissipation capability of the temperature-uniforming plate 3 and the centrifugal fan 2 makes the chip not need to perform a down-conversion operation for cooling, so as to better exert the performance of the chip. Because the frequency reduction treatment of the chip is not needed, a large amount of work of software development is avoided, and the cost is saved.

As shown in fig. 1, in the present embodiment, the dual air outlets 11 are disposed on the same frame edge of the frame body, so that the holding portion of the handheld device such as a mobile phone can be disposed more flexibly, for example, the dual air outlets 11 are disposed on the top frame edge of the mobile phone housing, and the other three frame edges (i.e., the left, right and bottom frame edges) of the mobile phone housing can be held by the user. Of course, in other embodiments, the dual outlets 11 may also be respectively disposed on different frame edges of the frame body, for example, one of the dual outlets 11 is disposed on a left frame edge of the mobile phone housing, and the other is disposed on a right frame edge of the mobile phone housing.

Specifically, in this embodiment, the air outlet 11 is located at a middle position in a longitudinal direction of the frame where the air outlet is located, where the longitudinal direction of the frame is a direction in which a size of the frame is relatively long, that is, a length direction of the frame. Set up air outlet 11 in the middle part position of frame limit, can the person of facilitating the use both hands hold electronic equipment, for example, middle part position at cell phone case's left frame limit or right frame limit sets up air outlet 11, so when the display frame of cell-phone shows with horizontal screen mode, the user can both hands hold the last frame limit and the lower frame limit of cell-phone respectively, because air outlet 11 is far away from last frame limit and lower frame limit, so the heat of effluvium can not influence user's hand, thereby help promoting the use and experience, especially in the scene of playing the recreation through the cell-phone, generally need show the picture with horizontal screen mode, and need to click etc. operation on the screen with both hands, air outlet 11 is close to the middle part of cell-phone and arranges and has greatly promoted user's use and experience. Similarly, in the present embodiment, the air inlet 12 is located at the middle position of the other side of the housing 1 opposite to the display screen, so that when the user holds the housing 1 with both hands, the air inlet amount is not affected, and the centrifugal fan 2 is ensured to perform an efficient heat dissipation function. Specifically, one side of the centrifugal fan 2, which is away from the second surface, may be disposed to abut against the inner wall of the housing 1, so as to shorten a distance from the air inlet 12 to the centrifugal fan 2, and also facilitate making the size of the electronic device in the thickness direction of the display screen smaller, for example, the mobile phone or the tablet computer may be made thinner.

As shown in fig. 2, in this embodiment, a heat dissipation air duct 4 is disposed in the housing 1, and the heat dissipation air duct 4 is connected to the centrifugal fan 2 and the air outlet 11. The hot air blown out by the centrifugal fan 2 reaches the air outlet 11 along the heat dissipation air duct 4, and the hot air is limited from flowing randomly to other positions in the shell 1 through the heat dissipation air duct 4, so that the influence of heat on other components in the shell 1 can be avoided. Specifically, the heat dissipation air duct 4 and the centrifugal fan 2 may be of an integrated structure, that is, the housing of the heat dissipation air duct 4 and the housing of the centrifugal fan 2 are the same component, and the heat dissipation air duct 4 and the centrifugal fan 2 may also be separately arranged and connected by welding, bonding, or the like. In order to reduce the length of the heat dissipation air duct 4 so that the hot air can be rapidly discharged to the air outlet 11, the heat dissipation air duct 4 is preferably a straight duct extending in a straight line in this embodiment. Further, since the outlet of the centrifugal fan 2 faces the axis perpendicular to the centrifugal fan 2, the outlet 11 can face the axis perpendicular to the centrifugal fan 2, so that the hot air directly passes through the heat dissipation air duct 4 and the outlet 11 in a straight path after leaving the centrifugal fan 2, thereby improving the heat dissipation efficiency. As shown in fig. 3 and 4, in order to guide the hot air in the heat dissipation air duct 4 to form an air flow that can rapidly pass through the air outlet 11, in this embodiment, a plurality of fins 5 are arranged in the heat dissipation air duct 4 near the air outlet 11, and an air flow channel is formed between two adjacent fins 5. The material of the fin 5 is preferably a material with high thermal conductivity, such as copper. The material of the casing of the heat dissipation air duct 4 is preferably a material with weak heat conductivity, such as plastic.

The housing 1 is usually made of metal material to improve the texture, for example, a metal middle frame is used in some mobile phones and a metal housing is used in some tablet computers in the market. When the framework of shell 1 was the better material of heat conductivility such as metal, the hot-blast heat of air outlet 11 can conduct the other parts of framework easily on the one hand, leads to electronic equipment's contact to experience the worsen, for example probably take place the low temperature scald, and the heat of the other parts of on the other hand shell 1 conducts air outlet 11 easily, leads to the temperature of air outlet 11 to uprise, influences the heat dissipation of target components and parts. For this reason, in this embodiment, the air outlet 11 is embedded with a heat insulation ring, and the heat dissipation air duct 4 is communicated with the heat insulation ring, that is, the hot air in the heat dissipation air duct 4 passes through the heat insulation ring and leaves the air outlet 11. The heat insulating ring can obstruct the heat from the edge of the air outlet 11, thereby avoiding the poor contact experience caused by the conduction of the heat of the air outlet 11 to other positions of the shell 1 and also avoiding the poor heat dissipation effect caused by the conduction of the heat of other positions to the air outlet 11.

In this specification, structures of each part are described in a progressive manner, and a structure of each part is mainly described to be different from an existing structure, and the whole structure and the part structure of the electronic device can be obtained by combining the structures of the parts.
