Staggered novel heat exchanger

The invention discloses a staggered novel heat exchanger. The staggered novel heat exchanger comprises a shell; at least one heat exchange structure is arranged inside the shell; the heat exchange structure comprises a plurality of heat flow channels into which waste gas is introduced and a plurality of cold flow channels; the plurality of heat flow channels and the plurality of cold flow channels are arranged in a staggered manner, and one cold flow channel is arranged between any two adjacent heat flow channels; the breakover direction of the heat flow channels is arranged perpendicularly to that of the cold flow channels. The high heat exchange efficiency of the staggered novel heat exchanger is guaranteed by use of the heat flow channels and the cold flow channels arranged in the staggered manner; the staggered novel heat exchanger is good in cooling effect, easy to produce and assemble, convenient to clean and long in service life; even after long-term use, the staggered novel heat exchanger is still capable of keeping excellent heat dissipation effect; furthermore, the staggered novel heat exchanger is portable, material-saving and very suitable for cooling oil fume waste gas.
