DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] like Figure 1As shown, a cooling system of a coagulation analyzer includes a water tank 12 and a diaphragm pump 13. The bottom of the water tank 12 is connected to a first L-shaped threaded coupling 8. The liquid inlet end of the diaphragm pump 13 is connected to the first L-shaped threaded coupling 8 through a first connecting pipe 1. The liquid outlet end of the diaphragm pump 13 is connected to the liquid inlet end of a first radiator 15 through a second connecting pipe 2. The liquid outlet end of the first radiator 15 is connected to the liquid inlet end of a second radiator 17 through a third connecting pipe 3. The liquid outlet end of the second radiator 17 is connected to the first elbow 10 at the top of the water tank 12 through a fifth connecting pipe 5.

[0020] There are two first radiators 15, two second elbows 16 are arranged between the two first radiators 15, and the two second elbows 16 are connected by a fourth connecting pipe 4. The two second elbows 16 are arranged relative to each other in an axisymmetric manner, and the two first radiators 15 can be connected in series through the two second elbows 16. The two first radiators, the two second elbows and the fourth connecting pipe cause the direction of the coolant to be bent twice by 90 degrees, thereby increasing the residence time of the coolant in the system, so that more heat can be taken away.

[0021] An internal threaded through-hole 14 is also provided between the second connecting pipe 2 and the first radiator 15, and the internal threaded through-hole is connected to a fourth elbow 20 for changing the flow direction of the coolant, and the liquid outlet of the fourth elbow 20 is connected to the liquid inlet of the first radiator 15. A fifth elbow 21 is also provided between the first radiator 15 and the second radiator 17, and the liquid inlet of the fifth elbow 21 is connected to the liquid outlet of the first radiator 15 through the third connecting pipe 3, and the liquid outlet of the fifth elbow 21 is connected to the liquid inlet of the second radiator 17 through the fifth connecting pipe 23.

[0022] The combination of the fourth elbow and the fifth elbow allows the direction of the coolant to change multiple times in the system, thereby increasing the residence time of the coolant in the system and improving the cooling effect.

[0023] The liquid outlet end of the fifth connecting pipe 5 is connected to the third elbow 18, and the third elbow 18 is connected to the first elbow 10 through the sixth connecting pipe 6. The sixth connecting pipe 6 is provided with a flow rate sensor 19. In other embodiments, the flow rate sensor 19 can be provided on other connecting pipes.

[0024] A plug 9 is also provided on the top of the water tank 12, and the lower end of the plug 9 is connected to a float switch 11. The float switch 11 is used to control the water level of the cooling water in the water tank.

[0025] A seventh elbow 22 is also provided on the top of the water tank 1, and a joint plug 7 is plugged into the end of the seventh elbow 22 in contact with the air. Cooling water can be added to the water tank by removing the joint plug, and after the cooling water is added, the joint plug is inserted into the seventh elbow 22.

[0026] In the present invention, the first radiator 15 adopts a water-cooled head with a cooling plate. The cooling plate can be a commercially available cooling plate such as a Peltier. The second radiator 17 is built with a serpentine condenser and a cooling fan. The condenser increases the contact area between the cooling water and the air to accelerate the heat dissipation; at the same time, the fan works to dissipate heat to the outside, so that the cooling water is cooled quickly.

[0027] When in use, first pull out the connector plug 7, add cooling water into the water tank 12, use the float switch 11 to adjust the height of the cooling water in the water tank 7, and when the cooling water in the water tank 12 meets the use requirements, insert the connector plug 7 into the seventh elbow 22. Start the diaphragm pump 13, so that the cooling water in the water tank 12 enters the pipeline in the system, and the cooling water passes through the first radiator 15 for the first cooling, and then passes through the second radiator 17 for the second cooling, and then flows back to the water tank 12 through the first elbow 10. In order to meet different cooling requirements, the water pumping amount of the diaphragm pump 13 is adjusted according to the real-time data transmitted by the flow rate sensor during operation, so that the plasma always maintains a suitable and stable temperature in the coagulation analyzer.
