Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides a plate heat exchanger performance testing tool, including a fixing frame 1, the fixing frame 1 is fixedly connected with a hot fluid inlet pipe 2, a cold fluid outlet pipe 3, a hot fluid outlet pipe 4, and a cold fluid inlet pipe 5 which are arranged through, the hot fluid inlet pipe 2, the cold fluid outlet pipe 3, the hot fluid outlet pipe 4, and the cold fluid inlet pipe 5 are all installed with a fluid temperature sensor 6, a fluid flow sensor 7, and a fluid pressure sensor 8, a sealing shell 9 is provided on the outer side of the fluid temperature sensor 6, the fluid flow sensor 7, and the fluid pressure sensor 8, the sealing shell 9 is movably connected with the hot fluid inlet pipe 2, the cold fluid outlet pipe 3, the hot fluid outlet pipe 4, and the cold fluid inlet pipe 5, and a leakage warning component 10 is installed on the sealing shell 9.

[0027] Specifically, the fixing frame 1 is composed of two correspondingly arranged fixing plates 101 and a connecting rod 102 , and one opposite side of the fixing plate 101 is fixedly connected to the connecting rod 102 .

[0028] Furthermore, the two ends of the hot fluid inlet pipe 2, the cold fluid outlet pipe 3, the hot fluid outlet pipe 4, and the cold fluid inlet pipe 5 are respectively provided with a plate heat exchanger connecting flange 11 and a fluid pipeline connecting flange 12, and the plate heat exchanger connecting flange 11 and the fluid pipeline connecting flange 12 are both provided with evenly distributed connecting holes 13.

[0029] Furthermore, a sealing gasket 14 is provided on the side of the plate heat exchanger connecting flange 11 away from the fluid pipeline connecting flange 12 , and the connecting hole 13 passes through the sealing gasket 14 .

[0030] It is worth mentioning that the leakage warning assembly 10 includes a fixed cylinder 1001, a piston plate 1002 is arranged in the fixed cylinder 1001, a warning rod 1003 is fixedly connected to the top of the piston plate 1002, the warning rod 1003 passes through the fixed cylinder 1001, and a spring 1004 is sleeved on the warning rod 1003 in the fixed cylinder 1001. When leakage occurs at the connection between the fluid temperature sensor 6, the fluid flow sensor 7, and the fluid pressure sensor 8, the sealing shell 9 can prevent the fluid from leaking directly, and can confine the fluid in the sealing shell 9. The pressure in the sealing shell 9 increases, prompting the warning rod 1003 to move up to remind the staff.

[0031] It is worth noting that a sealing ring 1005 is provided on the outer side of the piston plate 1002 , and the outer surface of the sealing ring 1005 is in close contact with the inner wall of the fixed cylinder 1001 to form a seal, thereby limiting the fluid in the bottom space of the piston plate 1002 .

[0032] It is worth mentioning that a through hole 1006 is provided on the top of the fixing tube 1001 , and the warning rod 1003 is disposed in the through hole 1006 , so as to facilitate the leakage of the warning rod 1003 .

[0033] Among them, the fluid temperature sensor 6, the fluid flow sensor 7, and the fluid pressure sensor 8 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0034] Working principle and process: The plate heat exchanger connection flange 11 and the fluid pipeline connection flange 12 at both ends of the hot fluid inlet pipe 2, the cold fluid outlet pipe 3, the hot fluid outlet pipe 4, and the cold fluid inlet pipe 5 are respectively connected to the plate heat exchanger and the corresponding fluid pipeline, so that the fluid can be normally introduced into and exported from the plate heat exchanger. The temperature, flow rate, and pressure of the hot fluid and the cold fluid entering and leaving are measured by the fluid temperature sensor 6, the fluid flow sensor 7, and the fluid pressure sensor 8, and the data is uploaded to the terminal. After data analysis, the performance of the plate heat exchanger can be tested. If there is a fluid leak at the connection between the fluid temperature sensor 6, the fluid flow sensor 7, and the fluid pressure sensor 8, the leaked fluid will be confined in the sealing shell 9 to prevent the fluid from directly overflowing and polluting the surrounding environment. When the fluid leaks, the pressure in the sealing shell 9 increases, and then the piston plate 1002 of the leakage warning component 10 is squeezed to move upward, so that the warning rod 1003 moves upward and leaks, so that the staff can find it in time, which is convenient for the staff to timely inspect the fluid leakage position, avoid deviation in the test data, and is conducive to the use of the plate heat exchanger performance test tooling.
