Plate heat exchanger is an important device for large air conditioning system exhaust energy recovery, high temperature flue gas waste heat recovery and computer CPU heat dissipation. The structure has a vacuum liquid filling head and a core body. The vacuum liquid filling head is arranged on both sides of the vacuum liquid filling channel, and one side of the vacuum liquid filling head is provided with a connecting pipe. The core body consists of the vacuum liquid filling channel and several plate fin channels. It is formed by overlapping at intervals.Vacuum brazing of surgical forceps - heat treatment process The vacuum filling channel is provided with partitions up and down, seals are provided on both sides, and fins can be arranged in the channel. The plate-fin channel is provided with partitions up and down, seals are arranged on both sides, and fins are arranged in the channel. Each plate-fin channel is divided into two parallel hot medium channels and cold medium channels by a strip.Control of retained austenite in tooth angle by vacuum carburizing heat treatment After assembly, the whole is horizontally inclined or vertically arranged. It is composed of stamped and formed concave and convex stainless steel plates. The concave-convex pattern between the two adjacent plates forms a 180-degree relative combination, so the concave-convex ridge lines between the two plates of the plate heat exchanger form staggered contact points.Six details of gas carburizing
