In in the groove outstanding of tray bottom.
Major defect is: since pallet and upper cover fasten closed, causing air duct inside hand dryer and cooling fin complete
Isolation, therefore, cooling fin can only lean on the heat transfer between pallet completely, and be taken out of heat by air duct inside hand dryer.
Such structure leads to heat dissipation for circuit board poor effect, and in the big place of flow of the people, hand dryer frequent starting leads to circuit board mistake
Heat, to easily cause circuit board damage, the problems such as hand dryer failure.
Utility model content
The purpose of the utility model is to provide a kind of hand dryer circuit board cooling structures, can effectively improve the heat dissipation of circuit board
Efficiency guarantees the stability that hand dryer is run when high frequency use.
Purpose of the utility model is realized as follows: a kind of hand dryer circuit board cooling structure, including pallet, upper cover,
Circuit board and the component being installed on circuit board, pallet are connected the installation chamber to be formed for mounting circuit boards with upper cover,
The pallet is equipped with first through hole, and upper lid is equipped with the second through-hole, is equipped with the heat dissipation for being placed in circuit board side in installation cavity room
Piece, cooling fin are equipped with several through slots, and first through hole, through slot and the second through-hole are sequentially communicated to form airflow channel.
In a preferred embodiment: the cooling fin includes bar shaped main body and is placed in the several of bar shaped body side
Partition, through slot are made of the gap between several adjacent partitions.
In a preferred embodiment: partition is additionally provided with transverse sheet on one end far from bar shaped main body.
In a preferred embodiment: the transverse sheet and the partition are perpendicular.
In a preferred embodiment: the back side of the bar shaped main body of the component and cooling fin abuts against.
In a preferred embodiment: the fin being placed between pallet and circuit board, institute are additionally provided on the pallet
The gap stated between fin and circuit board bottom forms heat-dissipating space.
The gas that first through hole, through slot and the second through-hole are formed is had the advantages that by using above-mentioned technical proposal
Circulation road makes air-flow effectively flow through fin surface, is quickly taken away after the heat transfer to cooling fin that circuit board generates, into one
Step improves the heat dissipation performance of circuit board.
