Background
Three principles of heat transfer: radiative heat transfer, contact heat transfer, convective heat transfer. Factors directly influencing the heat transfer efficiency in contact heat transfer: the refrigerant in the traditional heat exchanger flows in a transverse circuitous downward direction in a front row of heat exchange tubes and then flows in a rear row of heat exchange tubes to flow in a transverse circuitous upward direction until finally flows to an outlet of the heat exchanger to flow out (gas-liquid mixed refrigerant), so that the latent heat and sensible heat exchange process of the refrigerant is finished; in the circulation process, the heat exchanger transfers heat due to the metal connection of the fins, so that the temperature of the inlet pipe and the outlet pipe is relatively close, and the temperature difference is small; a space temperature gradient is formed, the requirement of large temperature difference of heat exchange is not met, so that when circulating air enters the heat exchanger, the temperature difference between the air (heat dissipation fluid) and the fins and the pipeline is not large, the optimal heat exchange temperature difference cannot be kept, and the heat exchange efficiency is low; and between the adjacent two layers of pipelines in the front and back, a relatively high temperature gradient is also provided, so that heat exchange interference between the adjacent two layers of pipelines in the heat exchange process can be caused, and the heat exchange efficiency is further reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a constant temperature difference heat exchanger, easy and simple to handle, can slow down and the turbulent flow to the refrigerant for direction, irregular turbulent flow, evaporation motion are done to the refrigerant, fully carry out the heat exchange, accelerate heat transfer thermal efficiency, promote the difference in temperature of fluid and fin, aluminum pipe, reach the purpose that promotes heat exchange efficiency, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a decide difference in temperature heat exchanger, includes radiating fin, heat exchange tube, choked flow piece, collector and side installed part, the heat exchange tube is S type structure, and the number of heat exchange tube is no less than two, the heat exchange tube distributes around being, and evenly be fixed with radiating fin between the heat exchange tube, radiating fin sets up with the heat exchange tube is perpendicular, the inside of every heat exchange tube all is equipped with a choked flow piece, both sides between the heat exchange tube all are fixed with a side installed part, the heat exchange tube access connection who is no less than two has a first of leading to, and the exit linkage of heat exchange tube has two of leading to the joint more, the export that leads to the joint two more and the access connection of collector.
Furthermore, the heat exchange tube is formed by bending and processing a copper tube, and the radiating fins are inserted in sequence from one side of the heat exchange tube.
Furthermore, the choked flow piece includes helical structure choked flow blade to the outside of choked flow blade and the inboard laminating of heat exchange tube, can carry out the vortex through helical structure choked flow blade to the inside of heat exchange tube, so that the inside velocity of flow of heat exchange tube reduces, and the heat transfer time obtains increasing, has improved the heat transfer factor of heat transfer contact surface, promotes the heat flux, and plays the turbulent flow effect through the choked flow of choked flow piece in the time, makes the heat transfer rate higher through a plurality of heat exchange tubes.
