Description of the Invention: [Technical Field] The present invention relates to a water-cooling tester, and more particularly to a water-cooling tester using an environmentally friendly refrigerant, combined with a load, and an external load. [Prior Art] In order to comply with the global environmental awareness, traditional CFCs have been completely eliminated since December 1995, and the currently widely used hydrochlorofluorocarbon (HCFCs) refrigerants are still With a small amount of ozone depletion potential (ODP) and global warming potentials (GWP), it is about to be shut down in the Montreal Convention, resulting in the current use of HCFC22 refrigerant. The main central air-conditioning main engine and machine tool cooler (such as machine tool cooler) bring a very serious impact, so the full use of hydrofluorocarbon (HFCs) new environmentally friendly refrigerant is imperative. However, because the new environmentally friendly refrigerant part belongs to the non-azeotropic mixed refrigerant series, it has temperature glide and composition shift in the gas-liquid phase coexistence zone, and the system operation performance and system refrigerant Problems such as leakage during the filling or assembly maintenance phase are different from pure refrigerants, which will have a considerable impact on system performance, so the system has re-planning problems. At present, there is no perfect solution to the problem of the temperature drop caused by the non-azeotropic refrigerant mixture in the domestic tool-machine water cooler manufacturer. Therefore, the development of a tool-cooling machine that matches the new environmentally friendly refrigerant is developed. It is absolutely necessary and quite urgent. On the other hand, when the machine tool performs high-speed machining operations, the spindle has a rapid temperature rise due to the high heat generated by the headstock bearings and the gear transmission. When there is a certain temperature difference between the components of the machine, the spindle The center will undergo thermal displacement and deviate from the center position of the column and the spindle head, which will seriously affect the machining accuracy. Therefore, in order to achieve the optimal temperature control precision during precision manufacturing, it is particularly important for the thermal management of the temperature control of the cooling machine of the machine tool, that is to say that the machine tool must be properly matched with a high-precision temperature control strategy. A constant temperature cooling device to suppress heat generation. At present, the machine tool cooler manufacturer conducts a water cooler test experiment. Generally, a water cooler is used and an additional heater load device station is used. The pipeline to be connected takes up a considerable space, causing the operator to work. It is extremely inconvenient to carry out the experimental test, which increases the difficulty of the water cooler measurement and the experiment. In addition, the heater load of the general test system is usually a non-adjustable type. For the academic unit and the cooler manufacturing waste business, I hope to understand the change of the new environmentally friendly refrigerant under different loads. There is a certain bottleneck. In addition, when the system is replaced with a new environmentally friendly refrigerant, the water cooler is subjected to a performance test. If the water cooler is required to replace the component with the same system and components, it must be very complicated. System processing steps (such as welding, vacuuming, pressure leak detection and re-injection of refrigerant, etc.) not only will, but also consume a lot of refrigerant, steel pipe and oxygen block 6 200848675 material will be used more than § no more Unnecessary time, the normal process of recycling the refrigerant to seriously affect the natural environment of the organism, money, and human resources. If the result of 'arbitrarily discharging the refrigerant will be strict', it will cause great damage to the earth. SUMMARY OF THE INVENTION The object of the present invention is to provide a water-cooling test machine, which is connected to the load by means of a water system. The water flow adjustment valve adjusts the opening of the valve to control different water flows, simulates the test application, and the external external load increases the utility of the water cooling test machine. Another object of the present invention is to provide a water cooling test machine, which can provide various environmentally friendly refrigerants for performance experiments, and can be quickly replaced by valves installed at the inlet/outlet of the cold system. Experiments with system components entering different system components reduce the shortcomings of system reset. Installation and inspection of the inlet and outlet of each element of the system
