The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0021] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0023] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0024] In one embodiment of the present invention, Figures 1 to 5As shown, a temperature control system structure of an integrated cold station box 1 is provided, including a box 1 and an electric control, a refrigeration host 2 and an air duct machine 3 arranged in the box 1, a ventilation hole 11 is provided on the side of the box 1, the electric control includes a cabinet 12 and a temperature sensor, the refrigeration host 2 is externally connected with a refrigeration water pipe 21 and a circulating water pipe 22, the refrigeration water pipe 21 and the circulating water pipe 22 are both used for external communication, the refrigeration water pipe 21 is provided with a first extension pipe 211, the circulating water pipe 22 is provided with a second extension pipe 221, a coil 31 is provided in the air duct machine 3, the water inlet end of the coil 31 is connected to the first extension pipe 211, and the water outlet end of the coil 31 is connected to the second extension pipe 221, a heater 32 is also provided in the air duct machine 3, the heater 32 is located on the side of the coil 31 close to the air inlet end, and the air duct machine 3 and the heater 32 are both electrically connected to the temperature sensor.

[0025] Furthermore, a heat preservation cotton 13 is provided on the top of the box 1, and the heat preservation cotton 13 is made of PU foam, and the thickness of the heat preservation cotton 13 is 13 mm. Specifically, the integrated cold station is usually set up outdoors. In the summer, when the temperature is high and the light is strong, the outer surface of the box 1 will heat up, and the top of the box 1 will heat up the fastest because it receives the most light. The temperature of the box 1 will increase the temperature inside the box 1, resulting in the normal operation of the refrigeration host 2. By setting the PU foam, the box 1 can be well insulated, reducing the impact of the outside on the temperature inside the box 1, and reducing the operating pressure of the duct machine 3.

[0026] Furthermore, the ventilation hole 11 includes an exhaust portion 111 and an air inlet portion 112. The exhaust portion 111 is arranged at the top of the side wall of the box body 1, and the air inlet portion 112 is arranged at the bottom of the side wall of the box body 1. An exhaust fan 113 is arranged in the exhaust portion 111, and a louver 114 is arranged in the air inlet portion 112. Specifically, the top of the box body 1 is exposed to high intensity sunlight, so the temperature of the top of the box body 1 is usually higher than the temperature of the side wall of the box body 1. At the same time, the refrigeration host 2 of the box body 1 will also generate heat, causing the temperature in the box body 1 to rise. The air with a higher temperature will float upward. The exhaust fan 113 can be used to discharge the hot air out of the box body 1, and the air with a lower temperature will pass through the louver 114 and enter the box body 1, thereby achieving a ventilation effect.

[0027] Furthermore, the exhaust fan 113 is electrically connected to the temperature sensor. Specifically, when the temperature in the box 1 is greater than 30°C, the exhaust fan 113 is turned on, and when the temperature in the box 1 is less than -2°C, the exhaust fan 113 is turned off; when the refrigeration host 2 is running, when the temperature in the box 1 is greater than 35°C, the air duct unit 3 and the coil 31 are turned on, and when the temperature in the box 1 is less than -2°C, the coil 31 stops running, but the heater 32 is running for heating, and the air duct unit 3 blows hot air to the coil 31 to prevent the coil 31 from freezing and cracking.

[0028] Working principle: the water temperature is lowered by the refrigeration main unit 2, the cold water is transported to the external refrigeration equipment through the refrigeration water pipe 21, and the used water is transported back to the refrigeration main unit 2 through the circulating water pipe 22 for cooling; the air duct machine 3 is used to reduce the temperature in the box 1 to ensure the normal operation of the refrigeration main unit 2. When in use, the cold water is transported to the external refrigeration equipment through the refrigeration water pipe 21, and the cold water enters the water inlet end of the coil 31 through the first circulation pipe, and the temperature in the air duct machine 3 is reduced by the coil 31 and then blown into the box 1 to achieve cooling of the box 1. The cooling water in the coil 31 enters the second circulation pipe through the water outlet, enters the circulating water pipe 22 through the second circulation pipe, and finally enters the refrigeration main unit 2; when the temperature in the box 1 is low, the heater 32 increases the temperature in the air duct machine 3, and then blows hot air to the coil 31 through the air duct machine 3, so that the coil 31 can maintain a certain temperature, avoid the cooling water in the coil 31 from freezing, and avoid the coil 31 from freezing and cracking.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
