Abstract: An efficient heat dissipation device for an engine includes a frame and an axial flow fan. The frame is connected to the engine. The axial flow fan is rotatably arranged on the frame and is driven by the engine crankshaft. In this embodiment, the axial flow fan supplies air along the fan axis. The size of the axial flow fan is large enough so that the air distribution area can cover the entire engine. The efficiency of heat dissipation is improved as the various parts of the entire engine can be air-cooled from one side at the same time. In addition, compared with the combined heat dissipation solution of a centrifugal fan and an air guide cover, the direct air supply of the axial flow fan directly blows the engine without kinetic energy loss, further improving the heat dissipation efficiency.

Abstract: Upon receipt of a synchronize cache command, valid host data size in the SRAM write buffer is checked. If the valid data size is greater than a predetermined value, valid host data in the SRAM write buffer is flushed directly into an open MLC block based on a one-pass transfer program. However, if the valid host data size is less than the predetermined value, the host data is not flushed to an open MLC block but is instead flushed into a temporary storage location to satisfy the command specifications for a command to synchronize a cache. The host data is maintained in the SRAM write buffer, which receives additional data until full. Once full, the host data in the SRAM write buffer is transferred to an open MLC block in one-pass. If the host data in the write buffer is lost, it may be recovered from the temporary storage location.
