Abstract: A dust collector for catching dust generated by temperature drop comprises a box, a plurality of separating boards, a plurality of catch boards, and a plurality of baffle boards. The separating boards partition the box to form an air flow channel. The catch boards and the baffle boards are staggered in the air flow channel; a portion of the catch boards are arranged in a central column to form a superimposition region along the vertical direction. The pores of the catch boards in the superimposition region are overlapped to make the air flow pour into the air flow channel easily. The baffle boards are staggered at the left or right of the catch boards, whereby the air flow takes more time to have a longer travel in the air flow channel, and dust is not accumulated in a single area but uniformly caught by the catch boards.
