Summary:The utility model relates to a wide channel honeycomb panel welding type heat exchanger, comprising a heat transfer core body, a pressure plate, a plate side coat, a pipe side coat, a flange, a blind plate and a pressure plate; wherein the heat transfer core body comprises two nest-shaped sheet spaces with openings on both sides in length direction, which are spot weld at the peaks with the peaks corresponding to each other; two sides of the two sheet spaces are assembly weld in length direction to form an inter-pipe weld and a plate pair; the two sheet spaces are weld in width direction to form an inter-pipe weld, thus an inter-pipe channel is formed between the two sheet spaces and an inlet and an outlet of the inter-pipe channel is formed at the openings in length direction of the sheet spaces; the plate pair and the adjacent plates of the plate pairs are in groups and are welded to form a inter-plate weld in length direction, thus a inter-plate channel is formed between the two plates pairs and the width direction of the plate pair is used as the inlet and the outlet of the inter-plate channel. The inter-plate channel and the inter-pipe channel are separated by the coat of the heat transfer core body and two independent runner systems for bearing the system pressure are formed. The utility model has the advantages of compact structure, big heat exchange area, high heat exchange efficiency and convenient cleaning.
