Description

Capillary vortex water conservancy diversion heat exchanger with protection device

Technical field

The utility model belongs to geothermal heat pump field and in particular to a kind of capillary with protection device is vortexed and leads Stream heat exchanger.

Background technology

Traditional ground energy air conditioner heat exchanger typically adopts one to three straight line cooling medium inputs of suit and output in casing Underground water, for the underground water contact heat-exchanging cooling transporting cooling medium with enter in casing, is then discharged, and is lowered the temperature by body Cooling medium continue cycling through at air-conditioner air outlet, by wind wheel blowing cold air, adjust and occupy indoor temperature.The knot of traditional heat exchangers Structure is limited, and heat exchange efficiency is low, thus lead to air-conditioning refrigeration not good.

A kind of spiral pipe heat exchange filed in " Nanjing Gu Deaidi environmental science and technology Co., Ltd " 28 days March in 2014 Device, by arranging the structure of some vortex shape coil pipes in the first working medium inner tube and the first working medium outer tube, theoretically increases Heat exchange area, thus draw the conclusion that can effectively lift operating efficiency.When in the actual experiment research process of applicant send out Existing, there is significant deficiency in this structure.First, coil pipe is copper medium, have to be larger than least radius, no when its bending is in vortex shape So copper pipe occurs bending dead angle, leads to brass tube fracture or water conservancy diversion not smooth.Now, exist between coil pipe and the first working medium inner tube Gap is much larger than the gap between coil pipe bent upon itself Internal and external cycle, leads to underground water can directly flow away from wide arc gap, without leading to Cross designer's default coil pipe own backlash, because this structural defect leads to underground water short circuit, the heat exchange finally recording is imitated Rate is even below traditional heat exchangers.

Applicant, can be by transforming heat-exchange device, lifting heat exchange and refrigerating efficiency through long-term R ＆ D, and order ground can be empty Tune can be designed to force the industry of cold output or business air-conditioning to be possibly realized, and has applied within 18th specially in August in 2015 Entitled " washable high-performance heat exchanger " for 201520621289.9 for the profit number.Anti- through market survey after a while and user Feedback, finds that, in the application process of above-mentioned patented technology, due to regional pressure of supply water difference or when cutting off the water, the water inlet of equipment is not Stable, easily cause heat exchanger dry combustion method or supercooling, ultimately result in shortened equipment life.

In consideration of it, applicant devises a kind of capillary vortex water conservancy diversion heat exchanger with protection device, changed by improving Hot device structure, while strengthening heat transfer effect, arranges protection device, and dry combustion method in the equipment of being avoided that or the situation of supercooling occurs.
