Abstract
The utility model discloses a horizontal volumetric heat exchanger with turbulent spirals, comprising a casing body, a head, a heat-exchange coil pipe, and a pipe plate, and is characterized in that supporting steel wires and turbulent spiral steel wires are arranged in each pipe of a U-shaped heat exchange pipe bundle, and the supporting steel wires are arranged around the turbulent spiral steel wires. The supporting steel wires and the turbulent spiral steel wires are connected for fixing by a steel wire fixing column. Meanwhile, in the casing body, a flow guiding plate is arranged horizontally along the both sides of the U-shaped pipe bundle. Heat transfer coefficient can be increased by 20-150%, and total heat transfer rate can be increased. The utility model is used for a hot water supply system. The volume of the heat exchanger can be reduced. Space occupation can be saved.
Description
The utility model belongs to the heat-exchange apparatus that general heat-exchange apparatus, particularly heat exchange medium directly do not contact.
At present, in the hot water supply system of general industry and civil buildings, application has volumetric heat exchanger, volumetric heat exchanger is that heat exchange coil is set in tank-like shell, with steam or high-temperature water is thermal medium, by heat exchange coil heat is transferred to medium in the housing from the tube wall of heat exchange coil,, realizes heat exchange as heating cold water.The heat exchange efficiency of existing horizontal volumetric heat exchanger depends on the temperature of length, tube wall area and the heat transferring medium of heat exchange coil, general Coefficient K=400～600 kilocalories/time rice
2Degree, heat exchange is abundant inadequately, often adopts the quantity of increase heat exchange coil or the measure of length, to increase heat exchange area.Because the loop length of heat exchange coil is subjected to the restriction of vome of shell size, so the growth of heat exchange efficiency is limited.
The purpose of this utility model is that the turbulent flow helical is set in heat exchange coil, can improve velocity of medium in the pipe, and can cause flowing of thermal medium to be turbulent flow, to quicken the heat transfer process of thermal medium, further improves heat exchange efficiency.
The horizontal volumetric heat exchanger that has the turbulent flow helical of the present utility model, form by housing, end socket, U type heat-exchanging tube bundle, tube sheet, it is characterized in that, in U type heat-exchanging tube bundle, be provided with supporting steel wire and turbulent flow helical steel wire in each root pipe, turbulent flow helical steel wire is fixed-type around supporting steel wire, connect with the fixation with steel wire post, be the helical type around supporting steel wire to keep turbulent flow helical steel wire.
In housing,, be horizontally disposed with deflector along U type tube bank both sides.
Turbulent flow helical steel wire also can be wrapped on the outer wall of heat-exchanging tube bundle.
The horizontal volumetric heat exchanger that has the turbulent flow helical of the present utility model, compare with existing horizontal volumetric heat exchanger, have the following advantages: when thermal medium flows in U type heat-exchanging tube bundle, improved flow velocity, no longer include laminar boundary layer stably, but form rapid turbulent flow, strengthened the heat transfer of thermal medium and U type heat-exchanging tube bundle tube wall at the tube wall place, heat transfer coefficient is increased significantly, can increase 20～150%; Deflector can force the medium U type heat-exchanging tube bundle district that flows through in housing, increase the heat exchange chance; When twining turbulent flow helical steel wire at the heat-exchanging tube bundle outer wall, can increase the stirring of washing away to the pipe outer wall, improve the exothermic coefficient of pipe outer wall to heated medium.Therefore, under the condition that does not increase heat-exchanging tube bundle length, can increase total heat exchange amount.That is to say, do not increase vome of shell, do not enlarge and take up an area of the space, improved heat exchange efficiency, play the economic benefit of saving investment.
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the front view that has the horizontal volumetric heat exchanger of turbulent flow helical.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the structural map of heat-exchanging tube bundle that has the horizontal volumetric heat exchanger of turbulent flow helical.
Fig. 4 is the B-B profile of Fig. 3.
Fig. 5 is that turbulent flow helical steel wire is wrapped in the structural map on the heat exchanger tube outer wall.
As seen from the figure, the horizontal volumetric heat exchanger that has the turbulent flow helical, by housing 1, end socket 2, U type heat-exchanging tube bundle 3, tube sheet 4 is formed, U type heat-exchanging tube bundle is the U shape steel tube of two 9 Φ 25mm be arrangeding in parallel of row, two ends are fixed on the tube sheet, it is characterized in that, in U type heat exchanger tube, be provided with the supporting steel wire 5 of Φ 5mm and the turbulent flow helical steel wire 6 of Φ 1～2mm, helical steel wire external diameter is 3/5 of a U type pipe caliber, Φ 15mm, the two ends of supporting steel wire 5 are fixed on the cross fixation with steel wire post 7, between turbulent flow helical steel wire and the supporting steel wire, 3～5 pitch in every interval are established a short fixation with steel wire post 8 and are connected and fixed.Both sides below the U type heat-exchanging tube bundle are provided with horizontal deflector 9 in housing, to improve heat exchange efficiency.When turbulent flow helical steel wire 6 is wrapped in the outer wall of U type heat exchanger tube, has the performance that causes turbulent flow equally.
