Abstract
The utility model discloses a solar heat exchanger which comprises a copper tube (1) and a radiating rib (2), wherein the copper tube (1) is wound into a spiral structure; the copper tube (1) is made of a copper strip; and the copper strip is wound and welded on the copper tube (1) along an outer surface plate of the copper tube (1). The inner and outer surfaces of the copper tube (1) are increased and a heat-transferring area of the radiating rib (2) is increased, so that the heat exchange efficiency is increased and an overall dimension of the solar heat exchanger is reduced.
Description
Technical field
The utility model relates to the solar facilities field, relates in particular to a kind of solar heat exchanger.
Background technology
As shown in Figure 3, copper tube turns to U-shaped, is welded with heat-dissipating fin on the copper tube, and heat-dissipating fin is made up of copper sheet one by one, and copper sheet is welded on the copper tube.Hot working fluid gets into from a copper sleeve, through copper tube, conducts heat through copper tube and heat-dissipating fin, flows out from another copper sleeve again.This structure copper tube limited length, heat exchange area is little, and radiating efficiency is low, seek out higher radiating efficiency, need do the heat exchanger size very big, is not easy to install and use.
The utility model content
Little to regular solar heat exchanger heat exchange area, the defective that heat exchange efficiency is low, the utility model technical problem to be solved provides the solar heat exchanger that a kind of overall volume is little, heat exchange area is big, radiating efficiency is high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of solar heat exchanger, comprise copper tube and heat-dissipating fin, and copper tube turns to helicoidal structure.
Heat-dissipating fin is made up of copper strips, spiral along the copper tube outer surface along normal direction coiling and be welded into the helical ring airfoil of copper strips.
The copper tube end is welded with copper sleeve.
The advantage of the utility model is that copper tube adopts helicoidal structure, makes under identical size; The surfaces externally and internally of copper tube increases greatly, has increased heat transfer area, and the copper tube outer surface is along spiral coiling and be welded on copper strips on the copper tube as fin of normal direction; Increased the area of dissipation of fin; Basically decide rate according to thermal conduction study: the heat conduction amount in the unit interval is directly proportional with thermograde and heat transfer area, owing to the heat transfer area that has increased, thereby has improved heat exchange efficiency.This kind heat exchanger profile is cylindrical; Compare with the heat exchanger of other equal heat exchange area; Its overall volume is little, is convenient to be installed in the small-sized heat storage water tank, is suitable for being installed in split pressure-bearing type solar water heater heat storage water tank; Can increase the heat of solar water heater, improve the heat that gets of solar water heater.
Heat-dissipating fin is made up of a copper strips; Be an integral body, can be when the coiling copper tube copper strips of coiling simultaneously and disposable being welded on the copper tube, need the copper sheet slices be welded on the copper tube; And solved copper sheet is welded on the difficulty on the spiral copper tube, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model solar heat exchanger;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Fig. 3 is the prior art structural representation;
Mark among the above-mentioned figure is: 1, copper tube, 2, heat-dissipating fin, 3, copper sleeve.
The specific embodiment
Fig. 1 is the structural representation of the utility model solar heat exchanger, and copper tube 1 turns to helicoidal structure, and heat-dissipating fin 2 is made up of copper strips, and copper strips spirals along normal direction at copper tube 1 outer surface and turns to the helical ring airfoil and be welded on the copper tube 1.Copper tube 1 end is welded with copper sleeve 3.Heat-transfer working medium gets into from a copper sleeve 3, through copper tube 1, conducts heat through the heat-dissipating fin on copper tube 1 and the copper tube 12, flows out from another copper sleeve 3 again.Heat transfer area is not only copper tube 1 surfaces externally and internally like this; Also increased the heat transfer area of fin 2, heat-dissipating fin 2 is made up of a copper strips, is an integral body; Can be when coiling copper tube 1 copper strips of coiling simultaneously and disposable being welded on the copper tube 1; Need the copper sheet slices be welded on the copper tube 1, and solve copper sheet is welded on the difficulty on the copper tube 1, improve production efficiency.Basically decide rate according to thermal conduction study: the heat conduction amount in the unit interval is directly proportional with thermograde and heat transfer area, owing to the heat transfer area that has increased, thereby has improved heat exchange efficiency.This kind heat exchanger profile is cylindrical; Compare with the heat exchanger of other equal heat exchange area; Its overall volume is little, is convenient to be installed in the small-sized heat storage water tank, is suitable for being installed in split pressure-bearing type solar water heater heat storage water tank; Can increase the heat of solar water heater, improve the heat that gets of solar water heater.
