Abstract

The utility model relates to a surrounding coil and internal ribbed tube type heat exchanger. A plurality of inner ribbed aluminium tubes are taken as tube bundles to increase the heat transfer coefficient of liquid at tube path side, and a shell path space is provided with a metallic coil for causing the other strand of liquid to enter. The liquid in the coiled tube can exchange heat with the liquid in the shell path of the heat exchanger without mutual influence. When the surrounding coil and internal ribbed tube type heat exchanger is matched with a burner, a multifunctional storage water heater for heating, shower and drinking can be formed.

Description

Surrounding coil and internal ribbed tube type heat-exchanger

The design is to " inner rib tubes type the fast water heater " (patent No.: 91211175.5) reach " stamen formula tubular heat exchanger in the internal-rib " (patent No.: the 91211489.4) technological improvement of described heat exchanger.

Above-mentioned " inner rib tubes type fast water heater " or " stamen formula tubular heat exchanger in the internal-rib " described heat exchanger can match with burner etc., and constitutes for heating, shower or drink the water heater of boiling water, but one is difficult to carry out simultaneously this three functions.For example: use it for heating, link, can produce dirt in the water cavity with radiator, then should not be simultaneously as the water boiler of Gong drinking.

The design is that one of addition makes the fluid in this metal tube can be with fluid heat exchange in the former shell side cavity but do not dye mutually mutually for the metal tube of the coiling shape of fluid turnover in the shell side cavity of former design heat exchanger.

The design's heat exchanger system by tube bank 1, shell 4, upper perforated plate 5, lower perforated plate 6, and connect 7 and 8 etc. for the pipe of fluid turnover shell side cavity and constitute, its architectural feature is as described below:

1, with several by the inner rib aluminum type tube of extrusion modling as the tube bank in this heat exchanger 1, promptly to be shaped on some and tube wall on the internal face of tube bank 1 be the longitudinal fin 2 of one, constitutes hot flame plume moving space that is tube side space Y by internal face and some fins 2 of tube bank 1; The internal face of tube bank 1 outside wall surface, shell 4, and go up lower

perforated plate

5 and 6 formation water cavity that is shell side space K such as forward surface; The fluid intake pipe that is shaped on the K space in the bottom of shell 4 connects 7, is shaped on K space fluid outlet pipe on the top of shell 4 and connects 8; Other has metal tube 10 coiling several internal-ribs tube bank 1 in the K space, its lower port lean out shell 4 the bottom, connect 11 close-fittings with pipe, its upper port lean out shell 4 top, connect 12 close-fittings with pipe.The upper end of this heat exchanger is furnished with enclosure 9.

2, for strengthening the exothermic coefficient of tube side side, be equipped with stamen pipe 3 in the smooth thin-walled of a closed at both ends (wherein an end can be shaped on supplied gas overflow aperture or slit), outer wall at every tube bank axle center part of 1, then by the internal face of the outside wall surface of middle stamen pipe 3, tube bank 1, and some fins 2 constitute the tube side space Y.

3, for not making the horizontal dissipated heat of flame of burner, the lower end of the design's heat exchanger can be made into the water jacket be wall the combustion chamber, be the R chamber, inner layer wall 13, outer wall 14 that R chamber system is coincided by axial line are constituted, the upper port of R chamber inner layer wall 13 and the outer rim kissing of lower perforated plate 6 merge welding, R chamber outer wall 14 is connected as a single entity with shell 4, and the annular space that is made of the indoor outer wall of R promptly is the some of water cavity K; Fluid inlet tubes connects displaceable on R chamber outer wall 14.Can be shaped on horizontal glory hole II on the water jacket wall of R chamber.

The advantage of this improvement property design is: the hot flame plume when tube side Y, the water in Heating K space, the water in K space can be used for diet and (or) shower; And another strand current pass through the inner chamber G of coil pipe 10, but do not dye mutually mutually but heat exchange with the hot water in K space, become the hot water effuser to connect 12, lead to radiating appliance etc.; Thereby can realize multifunctional usage.

Fig. 1 is structural representation that is the cut-away view of this heat exchanger K cavity and the partial cutaway diagrammatic sketch of R chamber of the design's heat exchanger, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the B-B profile of Fig. 1, and Fig. 4 is the schematic diagram of stamen pipe 3 during tube bank 1 axle center part is equipped with.

Among the figure: 1. the fluid outlet pipe that the fluid inlet tubes in stamen pipe 4. outer cover of heat exchanger 5. upper perforated plates 6. lower perforated plate 7.K spaces connects the 8.K space in the inner rib plate 3. of the internal-rib tube bank 2. tube banks 1 lower port pipe that connects 9. enclosures, 10. coil pipes, the 11. coil pipes 10 upper port pipe that connects 12. coil pipes 10 connects the inner chamber of R. combustion chamber, K. shell side space, outer wall Y. tube side space, inner layer wall 14.R chamber, 13.R chamber G. coil pipe 10

Claims
