Problems solved by technology
Although the traditional plate heat exchanger has high heat exchange efficiency, it must have a set of fastening tie rods with a certain length for assembly and positioning. Nearly half of the length of this set of fastening tie rods is reserved for installation. The process size, they still protrude outside the heat exchanger after the heat exchanger is assembled, occupying a large auxiliary space; and it is necessary to combine the plates, gaskets, fixed plates, and movable plates into a complete heat exchanger Matching gaskets and fastening nuts are generally required to be equipped with connecting flanges to connect with the pipe network, and the requirements for the connection and positioning of flanges and pipes are stricter, and the pipes connected to it must be trial-fitted with the flanges on the heat exchanger first , The installation can only be completed after welding; when the heat exchanger is small, due to the large outer diameter of the flange, interference between the flanges is easy to occur, and the installation space required for flange connection is still large

Embodiment Construction
[0017] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.
[0018] A plate heat exchanger consisting of a group of thin metal plates, gaskets separating each metal plate, a fixed plate 1 at one end of the equipment, and a movable plate at the other end. The entire heat exchanger is covered by a set of ten The tightening rods 2 are fastened together, see Figure 1. Both ends of the tightening rod 2 and the joints with the fixed plate 1 and the movable plate are all truncated cones, and the middle part is cylindrical.
[0019] On the fixed plate 1, there is a recessed step hole at the inlet and outlet of the fluid, and the hole is equipped with an interface 3, see figure 2 . The outer end face of the interface 3 is almost in the same plane as the fixed plate surface, and the interface 3 and the fixed plate 1 are fixed by axial set screws 5, and an O-ring 4 is installed between the interface 3 and the fixed pl...

A plate-type heat exchanger with novel structure features that whole heat exchanger is fastened by a group of fastening rod with conic ends for uniform stress and reliable sealing and the jointers coupled with extemal pipes are arranged in the concave step holes on the fixing plater for providing fluid inlet and outlet. Its advantages are compact structure, and small size.
Description
technical field [0001] The invention relates to a plate heat exchanger. Background technique [0002] The oil cooler matched with the serial compressor unit for ships is mainly used for cooling the lubricating oil of the oil-injected screw compressor in the unit, and its cooling effect directly affects the working performance of the screw compressor. For this reason, more efficient plate heat exchangers are used. Although the traditional plate heat exchanger has high heat exchange efficiency, it must have a set of fastening tie rods with a certain length for assembly and positioning. Nearly half of the length of this set of fastening tie rods is reserved for installation. The process size, they still protrude outside the heat exchanger after the heat exchanger is assembled, occupying a large auxiliary space; and it is necessary to combine the plates, gaskets, fixed plates, and movable plates into a complete heat exchanger Matching gaskets and fastening nuts are generally r...
