Abstract
The utility model discloses a symmetrical double-tube spiral coil heat exchanger comprising a hollow cylindrical closed cavity. The hollow cylindrical closed cavity comprises a stainless steel core pipe, an end cap and a hollow cylindrical tube, wherein a symmetrical double-tube spiral coil formed by curling a high-efficient low-finned tube is arranged at the outer end of the stainless core pipe inside the hollow cylindrical closed cavity, two ends of the spiral coil protrude out of the cavity to be connected with a cooled water inlet pipe, and the stainless core pipe is connected with a waterway connection pipe and a water outlet pipe. The heat exchanger adopts the high-efficient low-finned tube with integral fins and a substrate without causing thermal contact resistance and electrochemical corrosion of connection points, and has high strength and vibration resistance. The heat exchanger is capable of effectively increasing the heat exchanging efficiency, further, the closed hollow structure can effectively reduce dirt and dust and prevent fluid blocking, the symmetrical double-tube spiral coil structure compact in structure and small in volume is capable of effectively increasing using rate of the inside space of the cavity, thereby increasing the heating exchanging area between water and coolants, evidently improving the heat exchanging performance, and increasing the heat exchanging efficiency.
Description
Technical field:
The utility model relates to technical field of heat exchange device, especially relates to a kind of spiral coil heat exchanger.
Background technology:
Heat exchanger is the equipment with the part heat transferred cold fluid of hot fluid, therefore is called heat exchanger again.Heat exchanger is the common apparatus of chemical industry, oil, iron and steel, automobile, food and other many industrial departments, in producing, national economy occupies critical role, especially in Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., uses extremely extensive.The heat exchange efficiency that how to improve heat exchanger is the key issue place that the insider was concerned about always.
Practical content:
The purpose of this utility model is the market status of but undersupply vigorous at the high-end heat exchanger product demand of China and the two-tube spiral coil heat exchanger of a kind of symmetry that provides, and it has the advantages that volume is small and exquisite, heat exchange efficiency is high.
For achieving the above object, the utlity model has the hollow cylindrical closed cavity that constitutes by stainless steel core pipe, end cap and hollow cylindrical cylindrical shell, be provided with by efficiently hanging down the symmetrical two-tube spiral coil that the wing helix tube is rolled in stainless steel core pipe outer end in the cavity, the two ends of spiral coil pass cavity and link to each other with cooling water inlet pipe and water route tube connector, and stainless steel core Guan Zeyu water route tube connector and outlet pipe link to each other.
The radial spacing of described duplex tube helix coil pipe is consistent.
Described cylindrical shell outer end is provided with the footing mounting plate.
The beneficial effects of the utility model are: it adopts fin and matrix is the helix tube of holistic efficient low wing, does not have the electrochemical corrosion problem of thermal contact resistance and tie point, and intensity height, vibration resistance can effectively improve heat exchange efficiency; Secondly, the hollow structure of closed can reduce dirt and dust effectively, prevent fluid blockage, and duplex tube helix coil arrangement compactness, the volume of symmetry are small and exquisite, can effectively improve the space availability ratio of inside cavity, increase the heat exchange area of water and refrigerant, obviously improve heat exchange property, improve heat exchange efficiency.
