New Description: [New Technology Area] [0001] This creation is about a heat sink fin module, especially one that covers most of the bottom surface of the chassis and has a fan at its side to move the chassis. The heat generated by the internal high-power components is forced to disperse, and the heat-dissipating fin module of the chassis is improved in order to reduce the temperature inside and outside the box. [Prior Art] [0002] Please refer to Figure 1 for the blower device φ (A) used in the general MRT system. The reason for the easy failure is that the blower device (A) uses a single cooling fan (A1). It is installed inside the chassis (A2), which reduces the heat source of the highest temperature and zero components by direct air blowing; the single cooling fan (A1) in the chassis (A2) is directly blown to the design of the highest temperature and zero components, and also the high temperature. Covering the surrounding environment inside the chassis, causing the overall temperature rise of the chassis. The conventional heat sink (A6) has low heat dissipation efficiency, so that when the power crystal locked on the large heat sink works, the temperature rise cannot be effectively reduced, and the abnormal temperature rise is caused. A large number of power crystals burned out. ® [0003] Four sets of devices, such as cooling fan (A1) and CONVERTER power unit (A3), INVERTER power unit (A4) and drive start circuit (A5), are all placed inside the chassis (A2), and there is no device between them. Isolated from each other. When the cooling fan (A1) is started inside the chassis (A2), the wind will cause dust, oil, and the like to scatter inside the chassis (A2), causing serious insulation failure and short circuit. [0004] When the chassis (A2) is overheated, it can only be dissipated by a heat sink (A6) disposed on the bottom surface of the chassis (A2). However, the heat sink (A6) provided at the bottom end of the conventional chassis (A2) has insufficient coverage. Or the problem of poor heat dissipation, so 10120803"^ early number AQ1 (H page 3 / 16 pages 1012026145-0 M442010 [0005] [0006] [0007] [0008] [0009] often leads to the chassis (A2 If the temperature is too high and the internal components are damaged or the service life is reduced, this is the source of the main fault of the blower equipment (A) used in the current MRT system. In view of this, if the whole inside and outside of the chassis (A2) can be improved The heat dissipation effect will effectively protect the life cycle of the components of the blower equipment (A). [New content] The main purpose of this creation is to provide a heat sink fin module for the chassis to effectively solve the problem of poor heat dissipation of the conventional blower. The heat dissipation fin module of the creation chassis is covered on most of the bottom surface of the chassis, and at least includes: a heat dissipation substrate, one side of which is a connecting portion for the chassis connection, and a plurality of fin slots on the other surface; and a fin group formed by a plurality of fins arranged at equal intervals, each of the fins being provided with a fixing portion and the fin slot Tightly joined, a plurality of parallel first channels are formed between the fins, and each of the fins has a hollow cross section to form a plurality of second channels parallel to the first channel, so that heat energy of the heat dissipation substrate is actually transmitted to the fins And passing the first channel and the second channel to exchange heat with the contacted air, so as to greatly increase the effective heat dissipation area by using the first channel and the second channel inside the fins to make the fins The heat dissipation effect of the fins is formed at one end of the fins. The heat sink fin module further includes at least one first channel disposed at a side end of the fin group to cover the first passage and the first Two channels for forced driving heat dissipation 10120803# single number Α〇 101 page 4 / total 16 pages 1012026145-0 M442010 fan [0010] The above heat dissipation fin module is provided with two fans, and the inside of the chassis is provided Always The converter module and an AC converter are respectively disposed on the cooling fin module corresponding to the erection position of the DC converter module and the AC converter module.

At least one fan is added to the side of the heat sink fin module to enable the heat sink fin module to exert better heat dissipation effect. [0014] 3. When two separate DC converter modules and the AC converter module are provided When the fan is used, the actual operation status of the visible DC converter module and the AC converter module, respectively, according to the situation, respectively, the fan corresponding to the DC converter module or the AC converter is forced to disperse the heat of the large heat sink, and timely reduce The temperature inside and outside the cabinet.
