The Working Principle Of The Portable Laser Chiller

There are many different types of chillers on the market, which can be divided into two types:compression and absorption based on the principle of refrigeration. Compression chillers includes piston, centrifugal and screw type; absorption chillers can includes steam hot water and natural type. Most of the existing chillers uses 220V or 380V AC power supply and are generally used to chill large industrial machines with lack of portability.


Aiming at the shortcomings of the existing chillers, Coolingstyle provides a portable chiller to cool down small instruments and equipment that do not generate much heat. At the same time, it has a compact-structure, small-size, portable, DC-power-supply, low-power-consumption, Multifunctional portable constant temperature chiller with high energy efficiency ratio and wide application.

In order to achieve the above objectives, we have adopted the following technical solutions:

A multifunctional portable constant temperature water chiller, including a cabinet, a compressor, a condenser, a filter drier, a capillary tube, an evaporator, a condensation fan, and a heating tube, wherein: the compressor, the condenser, the filter drier, and the capillary tube , Evaporator, condensing fan and heating pipe are installed inside the cabinet; the compressor, condenser, filter drier and evaporator are connected in sequence, and the evaporator is connected with the compressor to form a refrigeration cycle, the filter drier and the evaporator is connected by a capillary tube; the evaporator is installed at the bottom of the box, and the compressor is installed above the evaporator; the back of the cabinet is provided with an air inlet, the front is provided with an air outlet, and the condensing fan is installed at the air outlet, The wind generated under the action of the condensing fan is used to cool the condenser. The constant temperature chiller uses DC power supply.

Working principle:

The compressor, condenser, filter drier, capillary tube and evaporator constitute the refrigeration system, and the evaporator, heating pipe and external equipment constitute the cooling liquid circulation system. The two systems complete the heat exchange between the refrigerant and the coolant in the evaporator. The purpose is to deliver constant temperature coolant to external equipment, so the temperature sensor is installed upstream of the water outlet connector. According to the temperature set on the display screen and the temperature detected on the sensor, the control system controls the start and stop of the compressor, the speed and the working status of the heating pipe, so that a constant temperature coolant is obtained. After the cooling liquid is delivered to the external equipment, it returns to the chiller to heat or cool again, and so on.

         The beneficial effects of this technology:

1. Compact structure, small size, weighs only 7.8kg, and adopts DC 12V, 24V, 36V or 48V power supply. Therefore, it only needs to be equipped with a small storage battery and can be used in any occasion without being restricted by environmental conditions.

2. The electric power consumption is only 200W or less, and the maximum cooling capacity is 450W, and the energy efficiency ratio is high.

3. The adopted power interface, water outlet connector, and return water connector are all quick-connect type, only need to connect the power supply and water pipe to use. You only need to set the required coolant temperature on the display, which is very convenient to use.
