Description

Technical Field

[0001] The present application relates to the technical field of heat exchanger production, and specifically to a heat exchanger positioning device and a method for using the same. Background Art

[0002] Plate heat exchanger is a common heat exchange equipment, usually used in the heat energy transfer process in industrial production. It consists of a series of metal plates, which are fixed together by sealing gaskets and frames to form a set of parallel fluid channels. When the cold and hot fluids flow through the two sides of the plate heat exchanger respectively, they exchange heat at the boundary between the metal plates. The heat of the hot fluid will be transferred to the cold fluid, thus achieving balanced heat transfer, so the installation of the metal plate is very important.

[0003] Existing plate heat exchangers are all installed manually, requiring the cooperation of multiple workers. In order to fix the metal plate between the fixing plates, it is necessary to use the grooves on the metal plate to coordinate with the fixing rods for positioning. During the installation process, the metal plate needs to be slightly bent and then placed between the fixing rods. Then, the metal plate is restored to a straight state under the elasticity of the metal plate, and the fixing rod is stuck in the groove. Due to the large number of metal plates and the lack of fixation before all of them are installed, one person is required to hold down the metal plate while another person installs the metal plate, which is more labor-intensive and resource-intensive.

[0004] Therefore, it is necessary to provide a heat exchanger positioning device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention
