Tube cooler:
The first type of hydraulic press cooler is tube type, which includes double tube type, vertical type, horizontal type, floating head type and so on. The characteristic of this type is that the water used for cooling flows through the inside of the tube, while the oil flows through the interval between the tubes, and the folded plate set in the middle allows the oil to deflect, and the two-way or even four-way flow method it uses allows Its cooling effect is more intense.
Composition: The tubular cooler consists of two parts: the outer shell and the inner cooler body. Due to the different specific structures, the external connection form is divided into pipe thread type and flange type; from the installation form, it is divided into horizontal type and vertical type; from the floating form, it is divided into floating disc type and floating head type; from the cooler tube structure It is divided into spiral tube type and finned tube type; from the baffle structure, it is divided into arcuate baffle, rectangular baffle, double weir baffle and circular baffle and other structural forms, all according to specific conditions. optional.
The outer casing includes: a cylinder, a water distribution cover and a return water cover. It is provided with inlet and outlet pipes and inlet and outlet pipes, as well as oil drain, drain, exhaust screw plugs, zinc rod mounting holes and thermometer interfaces.
The cooler body is composed of cooler tubes, fixed orifice discs, moving orifice discs, and baffles. Both ends of the cooler tube are connected with the fixed and movable orifice discs, and oil leaks from the cooler of the cooler loader; the fixed orifice disc is connected with the outer body flange, and the movable orifice disc can be freely stretched and contracted inside the outer body to eliminate the effect of temperature on the cooler tube. The effects of thermal expansion and contraction. The baffles play the role of enhancing heat transfer and supporting the cooler tubes.
Principle: The heat medium of the tube cooler is from the inlet of the tube on the cylinder body, passes through each baffle channel in sequence, and flows to the outlet of the tube in a tortuous manner. The cooler medium adopts double-pipe flow, that is, the cooler medium enters half of the cooler pipes from the water inlet through the water distribution cover, and then flows from the return water cover to the other half of the cooler pipe and enters the other side of the water distribution cover and the water outlet pipe. . In the process of double-tube flow, the cold medium absorbs the waste heat released by the heat medium and is discharged from the water outlet, so that the working medium maintains the rated working temperature.

Plate cooler:
The second type of plate type is also divided into herringbone and oblique corrugated types. The contact points arranged in the corrugated structure are used to make the fluid form turbulent flow when the flow rate is not high, which greatly improves the heat dissipation effect.
Plate heat exchanger is a new type of high-efficiency heat exchange equipment. It has the advantages of high heat transfer efficiency, compact structure, small footprint and easy installation. It can be easily combined into any flow form according to different process requirements. Therefore, it is widely used in petroleum, chemical, metallurgy, machinery, light industry, food, medicine, electric power, coating, heating and other industrial fields. In recent years, it has been used in cooling water, pure water and ultrapure water systems in the microelectronics industry. is also widely used.
Since the chilled water (refrigerant fluid) is not in direct contact with the circulating cooling water (working fluid), they transfer the heat of the circulating cooling water to the chilled water through the heat exchange fins, and the temperature of the higher temperature circulating cooling water is reduced to become Low temperature fluid, when the fluid on both sides of the heat exchange fins is constant temperature heat transfer,
It includes three processes:
1) The convective heat transfer process in which the circulating cooling water (working fluid) transfers heat to the walls of the heat exchange fins;
2) The heat conduction process through the heat exchange fins;
3) Convective heat transfer from the heat exchange fin wall on the other side to the chilled water (refrigerant fluid).

Air-cooled cooler:
The third type of air-cooled coolers are also divided into indirect, fixed and suspended types. It also has many features, its simple structure, small size, small weight and ease of use are all its advantages.
Air-cooled oil cooler (referred to as air cooler) is an aluminum alloy plate-fin heat exchanger with air as the cooling source. The heat exchange area is larger than the same volume, the heat transfer efficiency is high, and the air is used as the medium for heat exchange. Compared with the water-cooled radiator, it is not only easy to install and maintain, but also can avoid the oil-water mixing caused by the copper pipe burst, which will cause serious damage to the system. Secondly, for equipment (such as construction machinery) that needs to change the working location, there is no need to consider the supply of water sources, and there is no disassembly and reconstruction of the water circulation system. It is an environmentally friendly product that is increasingly widely used.
