DETAILED DESCRIPTION

[0018] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following will combine the drawing in the utility model, and the technical scheme in the utility model is clearly and completely described.

[0019] Example one, such as Figures 1-4As shown, a control module for a heat exchanger includes a housing 1, a heat exchanger 2 is installed in the housing 1, and a refrigerant inlet 3, a refrigerant outlet 4, a water inlet 5, and a water outlet 6 are respectively provided on the surface of the heat exchanger 2. The refrigerant inlet 3 and the refrigerant outlet 4 are respectively connected to a refrigerant input pipeline 7 and a refrigerant output pipeline 8;

[0020] The water inlet 5 is connected to one end of the first pipeline 9, the other end of the first pipeline 9 is connected to the second pipeline 10 through a tee, one end of the second pipeline 10 is set as a water outlet 11, and the other end of the second pipeline 10 is connected to the main pipeline 12; the water outlet 6 is connected to one end of the third pipeline 13, and the other end of the third pipeline 13 is connected to the main pipeline 12;

[0021] The first pneumatic diaphragm valve 14 and the second pneumatic diaphragm valve 15 are respectively installed on the second pipeline 10. The first pneumatic diaphragm valve 14 is located between the first pipeline 9 and the main pipeline 12, and the second pneumatic diaphragm valve 15 is arranged at the water outlet 11; an electromagnetic proportional control valve 16 is installed on the refrigerant input pipeline 7; a controller and a valve island are installed in the box body 1, and the signal output end of the controller is connected to the first pneumatic diaphragm valve 14, the second pneumatic diaphragm valve 15 and the electromagnetic proportional control valve 16 through the valve island.

[0022] Working principle:

[0023] After the second pipeline 10 and the third pipeline 13 are connected to the main pipeline 12, as shown in FIG. Figure 3 As shown, the first pneumatic diaphragm valve 14 is normally open, the second pneumatic diaphragm valve 15 is normally closed, and the electromagnetic proportional control valve 16 is normally closed. At this time, the refrigerant does not flow to the heat exchanger 2, that is, there is no refrigerant supply. In contrast, the water for injection enters along the main pipeline 12, passes through the second pipeline 10 and the first pipeline 9, enters the heat exchanger 2, and is then output to the main pipeline 12 again through the third pipeline 13, thus completing the cycle. If water is needed at this time, the controller simply opens the second pneumatic diaphragm valve 15 and closes the first pneumatic diaphragm valve 14. This allows the water for injection to pass through the third pipeline 13, the heat exchanger 2, and the first pipeline 9, and then be output from the water outlet 11 at the lower end of the second pipeline 10.

[0024] like Figure 4When the water for injection needs to be cooled, the electromagnetic proportional regulating valve 16 is opened by the controller, so that the cooling water can be input into the heat exchanger through the cooling medium input pipeline 7; and the required temperature can be set by the controller, and then the electromagnetic proportional regulating valve 16 is controlled by the controller to link the temperature to adjust the cooling medium flux, so as to realize the control of the temperature; then the first pneumatic diaphragm valve 14 is closed and the second pneumatic diaphragm valve 15 is opened by the controller, so that the water for injection enters the heat exchanger 2 along the main pipeline 12 through the third pipeline 13 to exchange heat with the cooling water in the heat exchanger 2, so as to realize the cooling effect of the water for injection, and then the water for injection is output from the water outlet 11 at the lower end of the second pipeline 10 after passing through the first pipeline 9.

[0025] When the cooling water is used up, the electromagnetic proportional regulating valve 16 is closed by the controller, and the second pneumatic diaphragm valve 15 is closed and the first pneumatic diaphragm valve 14 is opened, so that the water for injection returns to the initial circulation state again. If the cooling water needs to be used again, the above operation can be repeated.

[0026] In the second embodiment, as a further preferred solution of the first embodiment, the first manual diaphragm valve 17 is installed on the second pipeline 10, and the second manual diaphragm valve 18 is installed on the third pipeline 13. The first manual diaphragm valve 17 and the second manual diaphragm valve 18 are used to adjust the flow and back pressure, and when the second pipeline 10 and the third pipeline 13 are connected to the main pipeline 12, the first manual diaphragm valve 17 and the second manual diaphragm valve 18 can be closed to prevent the water for injection in the main pipeline 12 from entering the module during installation.

[0027] In the third embodiment, as a further preferred solution of the first embodiment, the temperature detector 19 is installed on the first pipeline 9, and the signal output end of the temperature detector 19 is connected to the signal input end of the controller. In this embodiment, the control panel can be installed on the surface of the box body 1, and the control panel is connected to the controller for parameter setting and temperature signal output display. The temperature of the outlet water can be measured by the temperature detector 19 to ensure that the outlet water is used after reaching the target temperature.

[0028] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
