Summary: HVAC heat transfer area, choose energy-efficient energy-saving heat exchanger has become the engineering inspection and acceptance is an important indicator, there are the traditional shell and tube heat exchanger heat exchanger efficiency year by year, maintenance capacity, condensate recovery difficult, infrastructure investment and power consumption and other issues. SECESPOL spiral winding shell heat exchanger is the most energy efficient on the market today, most reliable, highest performance and low cost heat exchanger.


-------------------------------------------------- ------------------------------

Twenty-first century, the environment and energy into the important issues facing humanity. To protect the environment and effective use of existing resources, energy use of resources is particularly important. For users, energy conservation, energy-saving heat exchanger means to reduce expenses, increase economic efficiency and enhance the competitiveness of enterprises.
The heat exchanger is HVAC, thermal power, chemical, oil refining, nuclear, metallurgical, food and pharmaceutical widely used devices, from the hybrid heat exchanger, regenerative heat exchanger to heat exchanger partitions are has a wide range of structural types. With the development of the theory of enhanced heat transfer and mechanical processing technology continues to progress, a number of special structural shapes, with high heat transfer surface structure, a large heat transfer area and the volume ratio of the new structure of compact heat exchangers. SECESPOL series spiral ribbed tube heat exchanger and the conventional shell and tube heat exchanger compared to the heat transfer coefficient, heat transfer efficiency, with considerable flexibility, applicability and reliability. Its unique spiral structure, advanced heat transfer mechanism and economic practicality, determine its energy efficient advantages.
A, SECESPOL screw threaded tube heat exchanger unique structure
SECESPOL series of tubes heat exchanger design will become a spiral wound reverse threaded pipe structure, which greatly changed the fluid flow state, the formation of strong turbulence effects and improve the heat transfer coefficient, reducing the heat transfer area, screw thread tube heat exchanger has the following characteristics:
(1) heat transfer efficiency. Media in the unique structure of the spiral thread of both vertical tube flow disturbance, but also rotation, completely destroyed the thermal boundary layer, and the forward movement of the fluid in the process of continuous change in direction, thus causing the cross section of secondary circulation The heat transfer enhancement, greatly improving the heat transfer efficiency.
(2) heat exchanger with welded seal, compact overall structure more secure than conventional heat exchangers, reliable, high degree of mechanization.
(3) with carbon steel, copper production compared to the heat exchanger, SECESPOL screw threaded tube heat exchangers corrosion resistant 316L stainless steel material, which is characterized as follows:
① high degree of rust - and anti-acid
② good welding - weld toughness
③ plasticity - pull-resistant, resistant moment, slip-resistant
④ oxidation - a protective layer of chromium oxide
(4), light weight, small volume occupied. Screw threaded tube heat exchanger only pass
System shell and tube heat exchangers or plate heat exchanger volume of about 1 / 5.
(5) turbulence makes the solids remain in suspension within the flow state,
Strong erosion of the wall while the media with anti-fouling and self-cleaning ability scale.
Two, SECESPOL screw threaded tube heat exchanger heat transfer mechanism
SECESPOL heat exchanger design for the current market, most of the asymmetrical flow of heat transfer conditions, the different heat transfer area on both sides of the shell volume up to 4.2 times the pipe volume in the steam - water heat exchanger field has no comparable benefits, and working conditions meet the requirements of a variety of complex, known as the "Prince of steam in Europe."
Three, SECESPOL full heat exchanger, condensate water temperature is low
SECESPOL heat exchanger compact, small size, but because of its unique spiral wound reverse threaded tube structure makes the length of each heat exchange tube up to 6m, can ensure that the steam in the pipe to stay longer, full condensation, the minimum temperature can be generally control in 3 ℃, the current trap in the civilian system, eliminating the need for the installation, significant savings in steam consumption, improve the efficiency of heat transfer equipment, reduce maintenance reduces operating costs and achieve energy saving.
Fourth, analysis of economic rationality
SECESPOL spiral winding shell heat exchanger has the following advantages:
(1) heat transfer efficiency (energy) - As the heat exchanger heat transfer area per unit volume, long tubes, so full of steam condensation, improve energy efficiency, saving 10% -15% of steam.
(2) long life - SECESPOL spiral winding shell heat exchanger is imported, long service life, design life of 40 years, and no noise during operation.
(3) Easy maintenance - SECESPOL spiral winding shell heat exchanger device entirely of stainless steel, corrosion-resistant, suitable for all water quality, and is all-welded construction, maintenance-free. Steam flow rate is designed to run at 5.5m / s, the internal is not easy to scale, easy maintenance, save a lot of annual maintenance costs.
(4) small size, save infrastructure investment - SECESPOL spiral winding shell heat exchanger, small size, heat capacity, so as opposed to indirect heat exchanger operating between both space and are required for large diameter pipe valve reduced, saving a lot of infrastructure investment.
(5) fast return on investment - compared with the traditional shell and tube heat exchangers, SECESPOL spiral winding shell heat exchangers in use about a year to recover the cost savings from the heat exchanger equipment investment.
Energy in China has become a social problem. As individuals of this society, whether corporate or individual should assume the mission to solve this problem. The SECESPOL spiral winding shell heat exchanger in the most simple, economical and reliable solution to heat problems soft drinks, is a worth promoting new energy-efficient heat exchanger.
