Existing refrigeration equipment is mainly divided into large fixed and small movable types. Large fixed equipment is generally placed in a specific room. One style is to provide a specific low-temperature environment for the entire room, and the other style is a box-type structure, which provides a specific low-temperature environment inside a specific box. Small movable equipment is mostly used in smaller experimental environments and places that need to maintain a low-temperature environment and transfer. One of its major advantages is that it can quickly and conveniently provide a specific low-temperature environment.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] See also Figure 1-6 The utility model provides an embodiment: a contact refrigeration system, comprising a control box 1 and a pipeline adapter box 2 arranged on one side of the control box 1, a refrigeration box 3 is arranged on one side of the pipeline adapter box 2, a top plate 4 is fixed on the top of the refrigeration box 3, and eight-tube supporting panels 401 for supporting eight-tubes are installed on both sides of the top of the top plate 4, upper refrigeration modules 5 are installed on both sides of the bottom end of the top plate 4, and a lower refrigeration module 6 is installed at the bottom of the refrigeration box 3, and the liquid outlet ends of the two upper refrigeration modules 5 are connected to the liquid inlet end of the lower refrigeration module 6;

[0021] A water cooling module 9 is installed on the inner wall of one side of the control box 1, and a water cooling circulation pump 10 is installed on the inner wall of the other side of the control box 1. The liquid outlet of the water cooling circulation pump 10 is connected to the liquid inlet of the water cooling module 9, and the liquid outlet of the water cooling module 9 is connected to the liquid inlet of one of the upper refrigeration modules 5 through a pagoda head, and the liquid outlet of the lower refrigeration module 6 is connected to the liquid inlet of the water cooling circulation pump 10;

[0022] A pump switch 8 and a thermostat 7 are installed on both sides of the surface of the control box 1, and a switch power supply 11 and an electrical control board 12 are installed on one side of the bottom of the control box 1. The output end of the pump switch 8 is electrically connected to the input end of the water-cooling circulation pump 10, and the output end of the thermostat 7 is electrically connected to the input end of the water-cooling module 9. The staff turns on the water-cooling circulation pump 10 and the water-cooling module 9 through the pump switch 8 and the thermostat 7 to work;

[0023] The electrical control board 12 receives feedback information from other components and adjusts the operating state of the refrigeration system according to the preset temperature requirements. The water-cooled circulation pump 10 continuously delivers the coolant cooled by the water-cooled module 9 to the upper refrigeration module 5 and the lower refrigeration module 6 through the pipeline adapter box 2. During the circulation of the coolant in the upper refrigeration module 5 and the lower refrigeration module 6, the coolant exchanges heat with the sample in the eight-tube joint.

[0024] The upper refrigeration module 5 includes an upper water receiving bracket 501 installed on the top of the refrigeration box 3, and a water cooling inlet 504 and a water cooling outlet 505 installed on the outer wall of one side of the upper water receiving bracket 501. A drain port 503 is installed on the outer wall of one side of the upper water receiving bracket 501 close to the lower refrigeration module 6. An upper water cooling circulation box 507 is installed at the bottom of the upper refrigeration module 5, and two symmetrical main refrigeration plates 506 are installed on the top of the upper water cooling circulation box 507. An upper cold storage plate 502 is installed on the top of the main refrigeration plate 506, and the outer periphery of the main refrigeration plate 506 is covered with a heat insulation cotton 508.

[0025] The coolant pumped out by the water-cooling circulation pump 10 is sent to the water-cooling inlet 504 through the pipeline adapter box 2, and the water-cooling inlet 504 injects the coolant into the upper water-cooling circulation box 507. At this time, the coolant transfers heat toward the upper cold storage plate 502 through the upper water-cooling circulation box 507 and the main refrigeration plate 506, thereby reducing the upper cold storage plate 502 and the sample temperature;

[0026] The lower refrigeration module 6 includes a lower water receiving tray 601 installed on one side of the bottom of the refrigeration box 3, and a lower water cooling circulation box 602 installed on one side of the bottom of the lower water receiving tray 601. The upper water receiving bracket 501 and the lower water receiving tray 601 are designed to support the leaked liquid that is misclassified during the subpackaging. The cold storage plate and the water receiving bracket can be cleaned by manually adding water, avoiding the accumulation of leaked liquid and polluting the operating environment.

[0027] A secondary cooling plate 603 is installed at the top of the lower water-cooled circulation box 602, and a lower cold storage plate 605 and an eight-slot liquid storage tank 606 are installed at the top of the secondary cooling plate 603 in sequence. The connection between the cold storage plate and the water receiving bracket is completed by nylon screws and nylon isolation columns to control heat transfer;

[0028] The outer periphery of the auxiliary cooling plate 603 is covered with a second heat insulation cotton 604. After the coolant is heated, it enters the lower water cooling circulation box 602 through the drain port 503. The auxiliary cooling plate 603 and the second heat insulation cotton 604 on the lower water cooling circulation box 602 further reduce the temperature of the coolant. The cooled coolant is injected into the water cooling module 9 through the water cooling circulation pump 10 again, thereby realizing the circulation function of the coolant.

[0029] The upper refrigeration module 5 uses two refrigeration plates, while the lower refrigeration module 6 uses one refrigeration plate. Insulation cotton is used around the refrigeration plates to separate the cold storage plate and the water cooling head, so as to control the heat transfer; the shape and number of the grooves on the surface of the upper cold storage plate 502 are determined according to the needs, and all are connected to facilitate the discharge of condensed water to the upper water receiving bracket 501;

[0030] Thermocouples are installed on one side of the upper water receiving bracket 501 and the lower water receiving tray 601. During the cooling process of the sample, since thermocouples are installed inside the lower water receiving tray 601 and the upper water receiving bracket 501, the thermocouples can be used to timely obtain the working temperature of the coolant in the upper refrigeration module 5 and the lower refrigeration module 6.

[0031] When the embodiment of the present application is in use, first, the staff places the eight-tube strip to be refrigerated and packaged in the eight-tube support panel 401, and then the staff turns on the water-cooled circulation pump 10 and the water-cooled module 9 through the pump body switch 8 and the thermostat 7 to work, and the electrical control board 12 receives feedback information from other components and adjusts the operating state of the refrigeration system according to the preset temperature requirements. The water-cooled circulation pump 10 continuously sends the coolant cooled by the water-cooled module 9 to the upper refrigeration module 5 and the lower refrigeration module 6 through the pipeline adapter box 2. During the circulation of the coolant in the upper refrigeration module 5 and the lower refrigeration module 6, the coolant exchanges heat with the sample in the eight-tube strip, and absorbs and removes heat by circulating the refrigerant and coolant therein, thereby reducing the temperature of the sample in the eight-tube strip, and the heated coolant continues to be pumped into the water-cooled module 9 by the water-cooled circulation pump 10 to cool down again, and the above steps are repeated, so that the eight-tube sample in the eight-tube support panel 401 is kept at a relatively low temperature state, thereby reducing the temperature difference of the sample before and after packaging, improving the sample quality and reducing the loss.
