Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to a vacuum cold liquid cooler. Background Art

[0002] Vacuum liquid cooler is an energy-saving device 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, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization.

[0003] The existing cooler has poor air tightness, the gas in the tube is prone to leakage, the vacuum environment is destroyed, and the cooling time is long, which cannot meet the current industrial needs.

[0004] To this end, we propose a vacuum liquid cooler. Utility Model Content

[0010] By adopting the above technical solution, the shell, the tube box and the tube sheet are first connected together by the first bolt, and then the sealing sleeve is installed. Finally, the sealing device is installed on the outside of the sealing sleeve. The installation is convenient, not only can it fit the shape of the sealing sleeve, but also can reduce the wear on the outside of the sealing sleeve, thereby ensuring the good sealing performance of the vacuum system, reducing gas leakage, and maintaining a stable vacuum degree.

[0011] When the cooling medium is placed in the first connecting pipe, it is connected to the connecting pipe of the refrigeration equipment or the liquid nitrogen pipeline through the connecting pipe, so that the cold air or cold liquid flows into the storage box through the connecting pipe. The check valve effectively prevents the cold air or cold liquid in the storage box from flowing out, and the thermal insulation cotton isolates the external heat, thereby maintaining a low inlet temperature, so that the cooling medium can absorb the heat of the cooled object more quickly, thereby accelerating the cooling process;

[0012] It should be pointed out that the lower the inlet temperature, the greater the temperature difference between the cooling medium and the cooled object, and the stronger the driving force for heat transfer.

[0013] Furthermore, the first sealing block and the second sealing block are each provided with a connecting block at the lower portion of the inner wall close to the first flange and the second flange, and the first flange and the second flange are each provided with a first mounting groove for mounting the connecting block at the lower portion of the outer wall.

[0014] By adopting the above technical solution, the connecting block of the first sealing block and the second sealing block is inserted into the first installation groove, so that the first sealing block and the second sealing block are preliminarily connected.

[0015] Furthermore, a second installation groove is provided on an upper portion of an inner wall of one side of the second sealing block, and one end of the first sealing block is inserted into the second installation groove.

[0016] By adopting the above technical solution, at the same time, one end of the first sealing block is inserted into the second installation groove, so that the first sealing block is further connected to the second sealing block.

[0017] Furthermore, a screw hole is provided at the top of the first sealing block inside the second mounting groove, and a threaded through hole for matching with a second bolt is provided at the top of the second sealing block near the screw hole, and the bottom end of the second bolt passes through the threaded through hole and is threadedly connected to the screw hole.

[0018] By adopting the above technical solution, after the first sealing block and the second sealing block are connected, the second bolt is passed through the threaded through hole and threadedly connected to the screw hole, so that the first sealing block and the second sealing block form a stable connection, thereby improving the sealing of the cooler.

[0019] Furthermore, the top end of the shell near the first pipe is connected to the second pipe, the bottom end of another group of pipe boxes is connected to the third pipe, the bottom end of the shell near the third pipe is connected to the fourth pipe, and two groups of relatively parallel supports are installed at the bottom end of the shell.

[0020] By adopting the above technical solution, the cooling medium enters through the first connecting pipe, passes through the pipe box and the shell, and is then discharged through the third connecting pipe;

[0021] The support can improve the overall stability of the shell.

[0022] Furthermore, the top inner wall and the bottom inner wall of the shell are fixedly mounted with a plurality of baffles arranged at equal distances and in an alternating manner. A plurality of transmission pipes are provided inside the shell. Both ends of the transmission pipes pass through the baffles and are connected to the tube sheets.

[0023] By adopting the above technical solution, the baffle is installed inside the shell, supporting and fixing the transmission pipe and changing the flow direction and speed of the fluid, thereby increasing the stability of the structure and making the fluid distribution more uniform.
