As an alternative embodiment, referring to fig. 2, a circulation fan 211 for agitating the first refrigerant is provided inside the heat exchange tube 21. The circulation fan 211 may adopt a fan blade structure commonly used in the prior art, and the first refrigerant is agitated by rotation of the fan blades, so that the heat exchange efficiency of the first refrigerant and the second refrigerant is improved.

The second impeller 8 may be of a conventional impeller structure, which is a mature technology and is not described herein.
The rotation of the impeller can stir the second refrigerant in the second cooling chamber 22, and the heat exchange efficiency between the second refrigerant and the first refrigerant in the second cooling chamber 22 is improved.
As an optional implementation manner, the heat exchange system in this embodiment further includes: the water inlet temperature sensor 5 is arranged at a refrigerant inlet of the second cooling cabin 22 and used for detecting the temperature of the seawater flowing into the cabin body of the second cooling cabin 22; the water outlet temperature sensor 6 is arranged at a refrigerant outlet of the second cooling chamber 22 and is used for detecting the temperature of the seawater flowing out of the second cooling chamber 22; and the controller 7 is electrically connected with the inlet water temperature sensor 5, the outlet water temperature sensor 6 and the impeller, and is used for receiving the temperature signal of the inlet water temperature sensor 5 and the temperature signal of the outlet water temperature sensor 6 and controlling the operation of the impeller according to the difference value of the two signals.

Two input ends of the controller 7 are respectively and electrically connected with the inlet water temperature sensor 5 and the outlet water temperature sensor 6, and two output ends of the controller are respectively and electrically connected with the second impeller 8 and the pump body 3.
Specifically, the temperature required for the seawater (second refrigerant) to flow into the second cooling compartment 22 and flow out of the second cooling compartment 22 is calculated according to the target heat exchange demand, and the temperature difference is set as the threshold Δ t. According to a heat calculation formula: when the heating system supplies the same amount of heat Q to the user, the supply/return water temperature difference Δ t is proportional to the amount of circulating water G. Namely, the temperature difference between the water supply and the water return of the system is large, and the circulating water quantity is small. When the temperature difference between the outlet water temperature sensor 6 and the inlet water temperature sensor 5 is greater than the threshold value Δ t, it is indicated that the water temperature in the second cooling chamber 22 is high, the circulating water amount is small, and the water temperature level will affect the heat exchange efficiency of the heat exchanger, so that the water flow in the second cooling chamber 22 is increased, the water temperature in the second cooling chamber 22 can be reduced, and the heat exchange efficiency of the heat exchanger is improved.
Therefore, when the temperature difference between the outlet water temperature sensor 6 and the inlet water temperature sensor 5 is greater than the threshold Δ t, that is, the temperature difference between the refrigerant flowing into the second cooling compartment 22 and the refrigerant flowing out of the second cooling compartment 22 is greater than the target required temperature difference, the controller 7 sends instructions to the pump body 3 and the impeller respectively: the rotating speed of the pump body 3 is increased to increase the circulating water quantity of the second cooling cabin 22 so as to meet the heat exchange requirement in the second cooling cabin 22; the rotating speed of the impeller is increased, the disturbance of the seawater in the second cooling chamber 22 is increased, and the temperature in the chamber is prevented from generating large temperature difference.
As an alternative embodiment, referring to fig. 1 and 3, a first impeller 102 is disposed in the first cooling compartment 1, and the first impeller 102 is rotatably disposed to agitate the first refrigerant.
Similarly, the first impeller 102 may adopt an impeller structure commonly used in the prior art, which is a mature technology and will not be described herein. The first impeller 102 can agitate the first refrigerant, thereby improving the heat exchange efficiency between the first refrigerant and the refrigerant in the condensation pipe.
As an alternative embodiment, referring to fig. 3, the top of the first cooling compartment 1 is provided with a compensation box 101, and the compensation box 101 is communicated with the first cooling compartment 1.
The compensation box 101 can store excessive liquid when the liquid in the first cooling chamber 1 is heated and expanded, so as to prevent the second cooling chamber 22 from generating larger pressure to the chamber body due to the expansion of the internal liquid, and ensure the stability of the heat exchange system.
When the heat exchange system of the embodiment is applied to the marine freezing/refrigerating equipment, the second refrigerant is seawater, so that the second refrigerant is convenient to obtain. Even if the seawater is covered with impurities due to salting out, electrochemical corrosion, etc., the second cooling compartment 22 is located outside the housing of the freezing/refrigerating apparatus, and is convenient to clean. In order to prevent seawater from corroding a condenser in a refrigeration system of the freezing/refrigerating equipment, the first cooling compartment 1 in the embodiment is positioned in a shell of the freezing/refrigerating equipment, and the first refrigerant is any refrigerant except seawater, such as fresh water which is convenient to obtain.
Therefore, in the above structure, the first cooling compartment 1 and the condensation pipe in the refrigeration system pipeline form a condenser of the refrigeration system, the second cooling compartment 22 and the heat exchange pipe 21 form another heat exchanger, and the first refrigerant flowing in the first cooling compartment 1 adopts fresh water, so that the maintenance cost of the condenser in the refrigeration system can be reduced, and the reliability of the heat exchange system can be improved.
