[Prior Art] 5 15 According to the conventional heat sink, there are various forms. For example, the heat dissipation vertically sets up a plurality of heat dissipation fins, and the heat dissipation device is disposed on the substrate, and the heat pipe is disposed on the substrate, and then the heat pipe is secondarily used, and (4) the fin '11 is heat pipe of the substrate by the heat pipe. On the hot fins of the government, to dissipate heat. Material = 1 ^ speed heat sink fin μ and the line of heat exchange material, usually a fan is placed on the side of the heat fin, aligning with the gap, can absorb air, so that cold air enters between the fins And achieve better heat exchange efficiency. Jin: The self-contained fins and fans are usually set by the wind shoulders π '4 edge. This placement allows the airflow to create a large flow resistance when entering the heat sink fins. In the case of heat dissipation, a large amount of auxiliary sound is generated, and the back pressure of the noise of the second == is also large. Relative fan follow 【New content】 The main purpose of the above is to provide a kind of heat dissipating device, which can solve the problem of reducing the material and increasing the air intake, and thus has the better heat dissipation effect of 20 M324397. The heat dissipation device provided by the present invention includes: a fixing seat, at least one heat pipe, a plurality of heat dissipating fins, and a fan; wherein the heat pipe is disposed on the fixing seat, and Fixing 5 seats to extend to the side and passing through the heat dissipating fins; the fan is disposed on one side of the heat dissipating fins, and the fan defines an air inlet surface and an air outlet surface according to a direction of blowing air The fan faces the space between the heat-dissipating fins by the air inlet surface or the air-out surface; the heat-dissipating fins are partially evacuated near the edge of the fan, and the heat-dissipating fins and the fan are Define a buffer space of 10 between. Thereby, the two gaps between the heat dissipation fins and the fan can be increased by the buffer space, whereby the standby flow resistance when the airflow blown by the fan enters the heat dissipation fins is reduced, and the fan can be reduced. The wind cuts of the blown air stream, which in turn reduces noise. [Embodiment] In order to explain the structure and characteristics of the present invention in detail, the following two preferred embodiments are described with reference to the following drawings, wherein: as shown in the first to third figures, the first creation In the preferred embodiment, the heat dissipating device 1G' is mainly composed of a fixing base n, a plurality of heat pipes 13, a plurality of heat dissipating fins 15, and a fan 17, and the middle portion is 13 and is set in the _ seating. 11, and extending from the landslide η to the side and upward, and passing through the heat sinks 15 .
