Die casting dedicated air-cooled chiller is an equipment used in the die casting industry to cool molds
or other related equipment in the die casting machine. This type of chiller adopts an air-cooled design,
usually including components such as compressor, condenser, evaporator, cooling fan, control system, etc.
Its working principle is to compress low-temperature refrigerant into high-pressure and high-temperature
gas through a compressor, then dissipate heat through the condenser to condense the gas into a liquid,
then pass through the expansion valve to reduce pressure and cool, and finally absorb heat through the
evaporator to form low-temperature refrigerant, achieving cooling effect in a cyclic manner. The air-cooled
design circulates the cooling medium for heat dissipation through a built-in fan, without the need for an
external water source, making it suitable for situations where water supply is inconvenient in some places.
The main advantages of air-cooled chillers for die-casting include:
1. Self sufficiency: No external water source is required, only an external power source is needed to
operate normally.
2. Easy installation: No need for pipeline connections, reducing installation costs and construction period.
3. Wide applicability: It can be applied to various environments, especially in places without water
resources or where it is inconvenient to receive water.
4. Easy to operate: Generally equipped with an automatic control system, it is easy to operate and maintain.
When choosing a dedicated air-cooled chiller for die-casting, it is necessary to consider the specific
requirements of the die-casting equipment, including cooling capacity, working environment, durability,
and other factors, and ensure the selection of suitable models and specifications to meet production needs.
Main Parts Description
1. Unit structure
The base is in the form of profile welding, the outer frame is formed steel, and the surface of the electric
control box is treated with electrostatic spray, which is bright and clean. The adhesion, hardness and
smoothness of the coating are higher than the Chinese national standard.
2. Compressor
Adopt hermetic scroll compressor, low carbon, energy saving and environmental protection; good
performance, low noise, trouble-free operation can reach more than 100,000 hours;
3. Expansion valve
The expansion valve adopts the American Emerson external balance thermal expansion valve, which
can automatically adjust the refrigerant flow according to the change of the system load to achieve the
automatic balance of the system operation; other main refrigeration system components such as drying
filter, solenoid valve, pressure gauge, etc. International famous brand (check the Main Part List).
4. Condenser
High-efficiency copper tube-sleeved aluminum fin condenser is used, with high heat exchange
efficiency and stable heat transfer performance. The refrigerant in the condenser flows in the heat
transfer tube, which is convenient for maintenance and cleaning.
5. Evaporator
The evaporator adopts high-efficiency stainless steel water tank coil type. The outer surface is smooth
and the cooling effect is good. The outer wall of the water tank is insulated with a 25mm thick PE
insulation board, which does not condense and reduces the loss of cooling capacity. This unit uses the
latest CAD design technology, CNC production and processing, compact structure and stable performance.
6. Electronic control system
The unit adopts 380V, 3-phase, 50Hz direct grounding AC system, and the voltage variation range is ±5%.
The internal power cables of the unit are arranged in accordance with national safety standards. The main
electrical components should be international famous brands such as Panasonic from Japan, Schneider
from French, PUNP from China, DuPont and EMERSON from the United States. The computer control
system of the unit automatically loads or unloads according to the change of the load to adjust the output
of the cooling capacity of the unit, so that the cooling capacity is accurately matched with the actual
cooling and heating load, so that the working compressor always maintains the highest efficiency state,
high efficiency and energy saving. The compressor is set to start the interval time to reduce the damage
to the electrical system when starting at the same time. The control system adopts a full Chinese display
controller, you can modify the setting language, which can realize remote control, and has dual protection
functions of user-level password and factory-level password, which is more secure. The operating
parameters of the unit can be input or modified through the display.
