Abstract
The utility model discloses a high-efficiency sleeve pipe type heat exchanger. The utility model comprises an outer pipe and an inner pipe, wherein the inner pipe is sheathed in the outer pipe. The pipe wall of the inner pipe forms a multi-head spiral groove shape. A plurality of spiral passages are formed between the outer pipe and the inner pipe. The utility model uses a coaxial counter-flow structure, the water flow flows through the inner pipe and a cooling medium flows through the spiral passages between the outer pipe and the inner pipe. As the spiral passages increase the heat exchange area of unit length, the water is in contact with the coolant in full circumference, the efficiency of the heat exchanger is improved. The reversely spiral turbulent flow of the water and the coolant strengths the mutual heat exchange and suppresses the deposition of solid particles on surfaces, and thus the utility model has the characteristics of high efficiency, compactness, good scale formation prevention, etc.
Description
Technical field
The utility model relates to a kind of air conditioner parts, especially relates to a kind of double pipe heat exchanger.
Background technology
Many thin-walled inner screw thread copper pipes of cover in outer tube of the general employing of the structure of traditional double pipe heat exchanger are walked refrigerant in the inner screw thread copper pipe, the heat exchanger water resistance of this structure is bigger, occurs icing the phenomenon of stifled and bursting by freezing when making evaporimeter easily.
The utility model content
The purpose of this utility model is to provide the double pipe heat exchanger of a kind of heat exchange efficiency height, compact conformation.
For reaching above-mentioned purpose, a kind of high-efficiency casing formula heat exchanger that the utility model provides comprises outer tube and interior pipe, and interior pipe box is in outer tube, and described inner pipe wall is the multi-head spiral groove shape, forms many helical ducts between outer tube and the interior pipe.
The utility model adopts coaxial counterflow configuration, current pass through from interior pipe, refrigerant flows through from many helical ducts between outer tube and the interior pipe, owing to many helical ducts have increased the heat exchange area of unit length and the full girth of water and refrigerant is contacted heat exchanger effectiveness is improved, the reverse spiral turbulence of water and refrigerant is more strengthened its mutual heat exchange, and can suppress the deposition of solia particle, thereby make and the utlity model has efficient, compact and have good characteristics such as resistive connection dirt on the surface.
No matter the utility model heat exchanger still is that condenser all can be realized high efficient heat exchanging with water as evaporimeter, can be widely used in handpiece Water Chilling Units, water source heat pump units and water-cooled packaged air-conditioner etc. have heat exchange efficiency height, compact conformation, the good characteristics of easy for installation, anti-fouling tendency.
