Embodiment Construction
[0049] The following is attached Figure 1-6 The application is described in further detail.
[0050] Standard plate-fin heat exchangers in related technologies such as figure 1 As shown, it includes a partition 13, fins 14, long seals 15, short seals 16, an upper cover 12, a lower cover 11, a left head 17 and a right head 18. Fins 14 are placed between two adjacent partitions 13 to form an interlayer, a pair of long seals 15 blocks the long sides of the fins 14 in one interlayer to form a heat medium interlayer, and a pair of short seals 16 blocks another interlayer The short sides of the inner fins 14 form a cold medium interlayer. The heat medium interlayer and the cold medium interlayer are superimposed and arranged at intervals from bottom to top, and a partition plate 13 is shared between adjacent heat medium interlayers and cold medium interlayers. The lowermost heat medium interlayer is connected with the lower cover 11, and the uppermost cold medium interlayer is c...

This application relates to the production of a heat exchanger that is convenient for repairing process leakage, which relates to the technical field of heat exchanger production, and includes the following steps: S1, processing accessories; S2, assembling the core body of the prototype; S3, shaping; S4, forming and replacing Heater; S5, test tightness; S6, repair welding of heat exchanger; S7, polishing and painting. Among them, in the process of repairing welding of the heat exchanger, the leaking solder joints are first blown off, and then the heat exchanger is preheated, and then the leaking solder joints are repaired with PSI fast repair glue and weld sealant, and the weld sealant is passed through Refrigerated injection gun packaging. The heat exchanger after repair welding needs to be pushed into the drying oven to dry and heat again until the fast repair glue and weld sealant are completely cured. The application has the advantages of convenient leakage repair and less damage to the components of the heat exchanger, which is beneficial to improving the production efficiency of the heat exchanger and reducing the scrap rate of the heat exchanger.
Description
technical field [0001] The application relates to the field of heat exchanger production, in particular to a heat exchanger production process that is convenient for leak repair. Background technique [0002] At present, the plate heat exchanger is an energy-saving equipment that realizes heat transfer between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature. Reach the indicators specified in the process to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. [0003] The standard plate heat exchanger consists of partitions, fins, long seals, short seals, left and right heads. Fins are placed between two adjacent partitions to form an interlayer, a pair of long seals seals the long side of one interlayer to form a hot medium interlayer, and a pair of short seals seals the short side of the other interlayer to fo...
