A plurality of heat dissipation holes are formed at appropriate positions around the periphery of the rear cover body. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1 to 3, a preferred embodiment of the display module M314390 of the novel cash register is shown. The cash register includes a body 1 and a display module 2. The display module 2 is mounted on the outside of the base 1. The display module 2 includes a housing unit 3, a circuit module 4, and a heat dissipation unit 5. The housing unit 3 includes a front housing 32 that is assembled with each other and cooperates to define an accommodation space 31, and a rear cover body made of a highly thermally conductive metal such as aluminum, copper, or an alloy thereof. 33.

Here, the inner surface 331 defining the rear cover 33 facing the heat generating unit 42 is the inner surface 331 of the rear cover 33, and the rear cover 33 is the rear surface 332 of the rear cover 33 on the surface away from the heat generating unit 42. In the present embodiment, the number of the heat generating elements 42 is five, which are the central processing unit 42a, the hard disk 42b, the memory 42c, and the lC42 (i and 42e.

In implementation, The first cover member 333 further has at least one positioning groove 336 recessed on the side of the third hollow portion 335, and the second cover member 334 has at least a limit card 337 corresponding to the positioning groove 336. In order to connect the four 盍 333 333, 334, and form the rear cover body %. Therefore, if the user wants to load and unload the hard disk 42b or the memory 仏, only the limit card of the first cover 334 is required. The 榫337 is separated from the positioning groove (4) of the first cover member 333, so that the hard disk 42b or the memory 42c can be conveniently loaded and unloaded. The display module of the novel cash register mainly uses the convection principle and the heat conduction principle to achieve the heat dissipation effect. The convection principle is formed by forming a first town 34 on the bottom side of the first cover member 333 of the rear cover body 33, and on the top side of the first jaw member 333 (ie, opposite the first hollow portion 34), The gums 7 are formed into a hollow portion 3 5. In the present embodiment, the second hollow portion 3 5 is arranged at a plurality of intervals on the top side of the first cover member 333. When the 351 is configured to heat up according to the operation of the heating element 42, it will be replaced with the adjacent air 5, and the hot air will rise and be discharged from the second hollow portion located above, while the cold air will be from below. The first hollow portion 34 is replenished into the accommodating space 3 via the through hole 442 of the branch 44, and is then exchanged with the heat generating member 42. If the convection cycle is performed, the heat dissipation effect can be achieved. The heat conduction principle of the M314390 is borrowed by one. The heat dissipation unit 5 achieves heat dissipation. The heat dissipating unit 5 includes six heat conducting materials for radiating the heat generating component 42 to the rear cover body 33 0. The heat conducting member 5; 1, and two for dissipating heat absorbed from the back cover body 33 in the air. Heat sink 52. Four of the insulating heat conducting members 51 are respectively attached to the central processing unit 42a, the memory 42c, the ICs 42d and 42e, and the rear cover 33, respectively.

In the present embodiment, the insulating and heat conducting member 51 is made of a flexible body (such as silicone) having insulation and thermal conductivity, and is adhered to the back cover 33 and the heating element 42 by adhesion such as double-sided tape. between. Moreover, in the embodiment, in order to save the material cost, the insulating and heat conducting members 51 are cut into appropriate areas, and then respectively attached to the respective heating elements 42; however, the number of insulating heat conduction # 51 may also be due to the cutting area. The number of implementations varies, and is not limited to those disclosed in this embodiment. The fins 52 are substantially fin-shaped and integrally formed on the back sides of the first cover 33 and the second cover 34 of the rear cover 33 (away from the side of the circuit group 4). By the heat dissipation unit A 5 being combined with the mechanism design of the rear cover body 33 and the circuit module 4, when the heat generating component 42 operates to generate thermal energy, the heat energy will be transmitted through the insulating heat conductive member 51, the rear cover body 33, and the heat sink member 52, Then escape in the air to achieve the effect of heat dissipation. Further, a plurality of heat dissipation holes 53 can be formed at appropriate positions on the periphery of the rear cover body 33. Accordingly, the heat energy generated by the heat generating component 42 can be simultaneously dissipated into the air via the heat dissipation holes 53, thereby improving the heat dissipation effect. M314390, in conjunction with the sixth aspect, in order to strengthen the adhesion between the insulating and heat conducting member 5i and the rear cover 33 and the heating element 42, the inner surface 33 of the rear cover 33 is convexly provided with at least one limit to be flattened from 338, and is limited to the platform 338. Corresponding to the position of the heat generating unit 42 , the insulating heat conductor 51 is more closely attached between the limiting block 338 and the heat generating component 42 . In this embodiment, the number of the offset platforms 338 is three and is respectively located at the positions corresponding to the central processors dKUd and 42e; however, the number of the offset platforms 338 can be increased or decreased according to design requirements. Referring to FIG. 7 again, the restriction platform and the rear cover 33 may be different bodies. Therefore, the restriction platform 338 is separately disposed on the inner surface of the rear cover body, and the restriction platform protrudes. The rear cover body 33 (four) face. According to this structure, the restriction platform 338 can be specially selected from materials having a better thermal conductivity, so that the heating element #42 (4) can be more quickly transmitted to the rear cover body... to improve heat dissipation efficiency. In summary, since the novel display module does not require additional assembly of the dissipating unit 2, the convection mechanism of the first hollow portion via the through hole and the second hollow portion is recognized and the fin-shaped heat sink is provided. The body is formed on the back side of the back cover body, and the heat-dissipating heat conduction member is used to conduct the heat-dissipating element to achieve the heat-dissipating effect, and the production cost is low and there is no noise and the P is early. In addition, the insulation guide member has a small occupation rate of one thousand, and the user can effectively use the accommodation space in the single housing of the housing, and the space utilization is good. Moreover, the display module of the present invention can be designed to be limited to the platform, so that the insulating and heat conducting members are closely attached between the heating element and the back cover body, thereby enhancing the heat dissipation effect and having good applicability. Therefore, the creative purpose of the novel can be achieved.
