Description

Cold-hot variable-temperature conversion control machine Technical Field The utility model relates to quick temperature control equipment, in particular to a cold-hot variable-temperature conversion control machine. Background At present, in industrial scenes such as novel composite material manufacturing, fine chemical engineering, biopharmaceutical industry and the like, precise temperature control equipment is often required, and the equipment is required to have rapid cold and hot response characteristics so as to meet the dynamic and complex production and manufacturing requirements. However, the conventional temperature control device is limited by thermal inertia of the heat conduction medium, and needs to be alternately executed for a long time to further heat/cool the heat conduction medium, so that the hysteresis effect of the temperature control device causes exponential increase of energy consumption, the energy efficiency ratio is lower than 35%, and the manually-adjusted temperature setting mode is difficult to adapt to the requirements of dynamically adjusting the temperature of various complex and changeable processes in the industries of novel composite material manufacturing, fine chemical engineering, bio-pharmaceuticals and the like. Disclosure of utility model The utility model aims to solve the technical problem of providing a cold-hot variable-temperature conversion controller which can realize quick cold-hot conversion and is easy to control, aiming at the defects of the prior art. In order to solve the technical problems, the utility model adopts the following technical scheme. The utility model provides a cold and hot alternating temperature conversion control machine, it is including the frame, be equipped with circulating pump, heater, water receiver, outlet pipe and cold water pipe in the frame, the one end of cold water pipe communicates in external cooling equipment, the other end of cold water pipe communicate in the water receiver, circulating pump go into the water end communicate in the water receiver, circulating pump go out the water end communicate in the water inlet of heater, the water outlet of heater communicate in the outlet pipe, the cold water pipe with be linked together through between the outlet pipe L shape return bend, be equipped with a switching valve on the L shape return bend. Preferably, the heater is arranged above the circulating pump, and the water reservoir is vertically arranged adjacent to the heater and the circulating pump. Preferably, the water outlet end of the circulating pump is communicated with the water inlet end of the heater through a Z-shaped bent pipe. Preferably, a side cover is arranged on the side part of the frame, and a heat radiation grid is arranged on the side cover. Preferably, a first connecting flange is arranged at the end part of the water outlet pipe, and a second connecting flange is arranged at the end part of the cold water pipe. Preferably, the cold water pipe is provided with a second switching valve, and the water outlet pipe is provided with a third switching valve. Preferably, a step part is arranged on the frame, a controller is arranged on the step part, and the first switching valve, the second switching valve and the third switching valve are respectively and electrically connected with the controller. In the cold-hot temperature-changing conversion control machine disclosed by the utility model, when descending equipment needs to be heated, the circulating pump runs and utilizes the heater to heat water quickly, and then the water is conveyed to controlled equipment through the water outlet pipe, and because the cold water pipe is communicated with the water outlet pipe through the L-shaped bent pipe, when the descending equipment needs to be cooled, the circulating pump and the heater are controlled to stop working, and meanwhile, the first switching valve is controlled to be conducted, so that cold water supplied by external cooling equipment can be directly conveyed to the controlled equipment, the control is convenient, hysteresis effect caused by overlong waterways can be avoided, and the cold-hot quick conversion function is well realized.
