This utility model discloses a dual-channel heating unit
water heater, wherein the bottom of the shell is provided with multiple pairs of longitudinally arranged baffles, the middle part of the water tank is provided with a partition, the middle shell is fixed to the top of the water tank, each baffle is inserted into the water tank, and the bottom of each baffle abuts against the bottom of the water tank to form a reciprocating and narrow flow channel. Each baffle is also provided with concave and convex textures on the outer side, and each baffle also has a slot connecting to the top of the middle shell. Each slot extends to the front and rear ends of the baffle, and each slot is also provided with an inwardly protruding limiting part on the inner side to divide the slot into multiple
insertion chambers. Multiple heating packs are inserted and fixed in the corresponding
insertion chambers. This utility model optimizes the flow channel in the water tank by setting baffles integrated with the middle shell, thereby achieving the effects of improving the matching of the whole vehicle end, accelerating the flow rate of
coolant in the water chamber, improving heat exchange efficiency, and preventing local overheating.
