Description
Technical field
The utility model relates to super high frequency radio frequency identification hand-held device, particularly a kind of heat abstractor of handheld terminal for electronic sealing read-write and handheld terminal.
Background technology
Because a large amount of large power, electrically sub-elements operationally can discharge amount of heat, high power module temperature is caused to raise, and the too high job stability that can affect electronic component of temperatures at localized regions.Therefore need the radiating effect improving high power module, reduce working temperature, ensure its stability, increase the service life.
Common radiating mode is finned on large power, electrically sub-element, absorbed fast by the heat of fin by large power, electrically sub-element, and by its radiating surface, heat is passed, thus reach cooling-down effect, but traditional fin shape is only the plane of a full wafer, moulding is too simple, cannot match with great-power electronic component structure, bad adaptability.Also there is same problem for radio-frequency (RF) tag, the read head (reader) of radio-frequency (RF) tag can Yin Wendu be too high causes job insecurity, and scanning makes mistakes.
Utility model content
The purpose of this utility model is to provide a kind of heat abstractor and handheld terminal of the handheld terminal for electronic sealing read-write, can solve the read head job insecurity caused because temperature is high, and the problem that radiator structure and high power module are not fitted.
According to an aspect of the present utility model, provide a kind of heat abstractor of the handheld terminal for electronic sealing read-write, comprising:
Be arranged on described handheld terminal inner and have the heat radiation with curved surfaces watt (1) of electronic device side towards printed circuit board;
Be opened in the multiple heat radiation counterbores (2) in described heat radiation watt (1);
Wherein, the high-power electronic device on the Closed End laminating printed circuit board of each heat radiation counterbore (2), each heat radiation counterbore (2) open end is to the housing of handheld terminal.
Preferably, also comprise: heat radiation counterbore (2) the openend side of described heat radiation watt (1) is posted for the heat-conducting silica gel sheet seamless applying with the housing of handheld terminal.
Preferably, described heat radiation counterbore (2) is cuboid groove, and cuboid is long with wide formed plane sizes with identical with the high-power electronic device size of its laminating.
Preferably, described heat radiation watt (1) edge is provided with multiple breach for corresponding handheld terminal inner structural members.
Preferably, described high-power electronic device is superfrequency module.
Preferably, described heat abstractor is made up of alloy material.
Preferably, also comprise: multiple screw thread (3) utilizing screw to be fixedly connected with the housing of handheld terminal.
According to another aspect of the present utility model, provide a kind of handheld terminal for electronic sealing read-write, described handheld terminal comprises described heat abstractor.
Compared with prior art, the beneficial effects of the utility model are: by providing a kind of heat abstractor, heat abstractor and high power module can be fitted, realize better radiating effect, thus make the work of read head more stable, avoid scanning to make mistakes.
Accompanying drawing explanation
Fig. 1 is the heat abstractor front view of the handheld terminal for electronic sealing read-write that the utility model embodiment provides;
Fig. 2 is the vertical view of the heat abstractor of the handheld terminal for electronic sealing read-write that the utility model embodiment provides.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, should be appreciated that following illustrated preferred embodiment is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Fig. 1 is the heat abstractor front view of the handheld terminal for electronic sealing read-write that the utility model embodiment provides, as depicted in figs. 1 and 2, be arranged on handheld terminal inner and the heat radiation with curved surfaces watt 1 of electronic device side is housed towards printed circuit board, it is the thermal conductive shell that printed circuit board covers, heat radiation watt 1 by alloy material make (such as, aluminum alloy material), utilize the characteristic of itself high specific heat capacity, absorb a part of heat, again by mode that heat transmits, unnecessary heat is passed to the housing of handheld terminal, its powerful heat sinking function, ensure that the job stability of high-power electronic device.
Heat radiation watt 1 be arranged on there is multiple electronic device printed circuit board above, heat radiation watt 1 is provided with multiple heat radiation counterbore 2 for dispelling the heat to the high-power electronic device on printed circuit board, the high-power electronic device on the Closed End laminating printed circuit board of heat radiation counterbore 2.Heat radiation counterbore 2 can be the groove of fitting with the high-power electronic device on printed circuit board, for dispelling the heat to the high-power electronic device with its laminating, groove can be cuboid groove, also can be the groove of other shapes, for cuboid groove, cuboid is long with wide formed plane sizes with identical with the high-power electronic device size of its laminating.Therefore, when handheld terminal works, utilize cuboid groove length and wide formed plane, the heat Quick diffusing of the high-power electronic device with its laminating is gone out.Heat radiation counterbore 2 open end is to the housing of handheld terminal, and the housing of handheld terminal can have ventilation hole, makes the temperature of high-power electronic device to remain at working temperature.Wherein, high-power electronic device is superfrequency (UHF:Ultra High Frequency) module.
The heat radiation counterbore 2 openend side of heat radiation watt 1 is posted for the heat-conducting silica gel sheet seamless applying with the housing of handheld terminal.Heat radiation watt 1 edge also has multiple breach for corresponding handheld terminal inner structural members, and in order to be adapted to the inner structural members of handheld terminal, breach can be any one shape, there is certain flexibility.In addition, heat radiation watt 1 also comprises multiple screw thread utilizing screw to be fixedly connected with handheld terminal housing.
In sum, the utility model has following technique effect: by providing a kind of heat abstractor, heat abstractor and UHF module can be fitted, realize better radiating effect, thus makes read head can continous-stable work for a long time, avoids scanning to make mistakes.
Although be described in detail the utility model above, the utility model has been not limited thereto, and those skilled in the art of the present technique can carry out various amendment according to principle of the present utility model.Therefore, all amendments done according to the utility model principle, all should be understood to fall into protection range of the present utility model.
