With the continuous development and popularization of scientific instruments in recent years, all kinds of instrument supporting products have also developed by leaps and bounds. One of them is a circulating water plate heat exchanger. Its function is to take away the heat generated by the instrument through relatively low temperature water, so that the temperature of the instrument part is kept at a low level.At present, circulating water plate heat exchangers are widely used in laser marking machines, laser cutting machines, laser welding, laser drilling and other laser equipment.At present, circulating water plate heat exchangers are widely used in laser marking machines, laser cutting machines, laser welding, laser drilling and other laser equipment.Due to the unstable water pressure and the rust of the tap water, the contradiction of the water shortage is becoming more and more prominent, and the equipment and equipment (especially precision instruments) are increasingly demanding the water quality and temperature of the cooling water. Circulating water plate heat exchangers have become the first choice for more and more users.
Circulating water plate heat exchangers are classified into uncooled and cooled types according to their functions.The principle of uncooled type is generally simple, mainly consisting of a water pump, radiator, fan and water tank.Its role can only be used to cool down, generally it can not control temperature, and the temperature of the water depends on the ambient temperature of the location.Since the fan is used to blow water onto the radiator to achieve cooling, the water temperature in the instrument waterway cannot be lower than the ambient temperature.Therefore, the uncooled circulating water heat exchanger is generally applicable to instruments or equipment that have low requirements for water temperature control and low heat production.
Refrigeration circulating water heat exchangers can be divided into start-stop type and non-start-stop type according to their different working modes.The common principle is to use a temperature controller for temperature control. The compressor is cooled and then exchanged with water to lower the temperature of the water.
