Thin rectangular channels are formed between the various plates, through which heat is exchanged. They have the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. The main types of plate heat exchangers are frame type and brazed type, and the plate forms are mainly herringbone corrugated plates, horizontal straight corrugated plates, and nodular plates.

[0023] A heat exchanger with a connection structure includes a plate heat exchanger body 1. A refrigerant inlet 2, a refrigerant outlet 3, a heat medium inlet 4, and a heat medium outlet 5 are fixedly connected to the surface of the plate heat exchanger body 1. A connecting pipe 6 is inserted into the refrigerant inlet 2. A locking structure 7 is provided on the surface of the refrigerant inlet 2. The locking structure 7 includes a shaft seat 71, a rotating shaft 72 fixedly connected to the surface of the shaft seat 71, a rotating seat 73 movably connected to the surface of the rotating shaft 72, a spring damper 74 fixedly connected to the surface of the rotating seat 73, a connecting layer 75 fixedly connected to the surface of the spring damper 74, a sealing layer 76 fixedly connected to the surface of the connecting layer 75, a fixing layer 77 fixedly connected to the surface of the sealing layer 76, a fixing plate 78 fixedly connected to the surface of the fixing layer 77, and a handle 79 fixedly connected to the surface of the sealing layer 76. The locking structure 7 allows for... After the connecting pipe 6 is inserted into the refrigerant inlet 2, the locking structure 7 is rotated by the handle 79 to cover the surface of the connecting pipe 6 with the sealing layer 76 and the fixing layer 77. The fixing plates 78 of the two adjacent sets of locking structures 7 are then connected to each other by bolts, so that the sealing layer 76 and the fixing layer 77 are pressed tightly onto the surface of the connecting pipe 6, locking the connecting pipe 6 and the refrigerant inlet 2 together. This quickly completes the installation of the connecting pipe 6 and facilitates the disassembly and maintenance of the connecting pipe 6 later. The rubber pads on the surfaces of the sealing layer 76 and the fixing layer 77 that contact the refrigerant inlet 2 and the connecting pipe 6 further increase the sealing performance. The installation steps of the refrigerant outlet 3, the hot medium inlet 4, and the hot medium outlet 5 are the same as those of the connecting pipe 6. Spring dampers 74 are provided. When liquid is transported into the heat exchanger through the connecting pipe 6, the connecting pipe 6 will vibrate. The spring dampers 74 absorb the vibration generated by the connecting pipe 6, reducing the damage to the rotating shaft 72 caused by the vibration and increasing the service life of the locking structure 7.

[0024] Furthermore, four sets of connecting pipes 6 are provided, which are respectively inserted into the refrigerant inlet 2, refrigerant outlet 3, heat medium inlet 4 and heat medium outlet 5, and the heat exchange medium is transported into the plate heat exchanger body 1 through the connecting pipes 6.

[0025] Furthermore, four sets of locking structures 7 are provided on the surface of the refrigerant inlet 2. The four sets of locking structures 7 are distributed circumferentially on the surface of the refrigerant inlet 2. The four sets of locking structures 7 are connected to each other by bolts, connecting the connecting pipe 6 to the refrigerant inlet 2.

[0026] Furthermore, the four sets of locking structures 7 constitute a locking assembly. A locking assembly is provided on the surface of the refrigerant inlet 2, refrigerant outlet 3, heat medium inlet 4, and heat medium outlet 5. The four sets of connecting pipes 6 are connected to the refrigerant inlet 2, refrigerant outlet 3, heat medium inlet 4, and heat medium outlet 5 respectively through the locking assembly.

[0027] Furthermore, two sets of bearing seats 71 are symmetrically arranged, and the two ends of the rotating shaft 72 are respectively fixedly connected to the inside of the two sets of bearing seats 71. A circular groove is opened on the surface of the rotating seat 73, and the rotating seat 73 is movably connected to the surface of the rotating shaft 72 through the circular groove. Two sets of spring dampers 74 are symmetrically arranged, one end of the spring damper 74 is fixedly connected to the rotating seat 73, and the other end of the spring damper 74 is fixedly connected to the connecting layer 75. The cross-sections of the connecting layer 75, the sealing layer 76, and the fixing layer 77 are all fan-shaped. The surfaces of the sealing layer 76 and the fixing layer 77 that contact the refrigerant inlet 2 and the connecting pipe 6 are provided with rubber pads to increase the sealing performance and reduce the impact of vibration generated when the connecting pipe 6 transports liquid on the locking structure 7. The bearing seat 71 is fixed on the outer surface of the refrigerant inlet 2, and the locking structure 7 can rotate around the rotating shaft 72. The connecting layer 75, the sealing layer 76, and the fixing layer 77 are all tightly fitted to the surfaces of the refrigerant inlet 2 and the connecting pipe 6.

[0028] Furthermore, two sets of fixing plates 78 are symmetrically arranged on the surface of fixing layer 77. The two sets of fixing plates 78 are connected to each other by bolts, so that the sealing layer 76 and fixing layer 77 are pressed on the surface of connecting pipe 6, locking connecting pipe 6 and refrigerant inlet 2 together.

[0029] Furthermore, the surface of the refrigerant inlet 2 is provided with rounded corners, and the side of the sealing layer 76 that contacts the refrigerant inlet 2 is also provided with rounded corners, further increasing the sealing performance of the sealing layer 76.

[0030] Working principle: The installation steps of refrigerant inlet 2, refrigerant outlet 3, heat medium inlet 4, and heat medium outlet 5 are the same as those of connecting pipe 6. Only the installation process of refrigerant inlet 2 and connecting pipe 6 is described here. Spring damper 74 is existing technology. During installation, first insert connecting pipe 6 into refrigerant inlet 2. Locking structure 7 can rotate around shaft 72. By rotating locking structure 7 through handle 79, sealing layer 76 and fixing layer 77 are covered on the surface of connecting pipe 6. The fixing plates 78 of adjacent sets of locking structures 7 are connected to each other by bolts, so that sealing layer 76 and fixing layer 77 are pressed on the surface of connecting pipe 6, locking connecting pipe 6 and refrigerant inlet 2 together, thereby quickly completing the installation of connecting pipe 6 and facilitating the disassembly and maintenance of connecting pipe 6 later. After the four sets of connecting pipes 6 are installed, heat exchange medium is transported into plate heat exchanger body 1. At this time, connecting pipe 6 will vibrate. Spring damper 74 absorbs the vibration generated by connecting pipe 6, reducing the damage to shaft 72 caused by vibration and increasing the service life of locking structure 7.
