Abstract
The utility model discloses a heat-exchanging device, consisting of heat exchanger with a tubular shell, a hot water recycling pump, a hot water inlet tube and a hot water outlet tube. A refrigerant water outlet and hot water outlet are arranged correspondingly at the two ends of the shell body of the heat exchanger with a tubular shell. The refrigerant inlet communicates with the interior cavity of the shell. The hot water recycling pump extends through the hot water inlet tube and communicates with the hot water inlet of the heat exchanger with a tubular shell. At least one layer of multi-head corrugated spiral coil pipes with different bending radius are arranged in the cavity of the shell body with the multi-head corrugated spiral coil pipes sheathed sequentially according to the bending radius and with all the both ends of all the multi-head corrugated spiral coil pipes communicate hermetically with the hot water inlet. Due to that all the multi-head corrugated spiral coil pipes with different bending radius constitute peculiar tube-side and shell-side flow passages, the heat medium and the refrigerant are capable of flowing in an impulse type in respective flow passages. Thereby, convective heat transfer is intensified and heat transfer coefficient is very high. Besides, the utility model has the advantages of small volume and light weight.
Description
Affiliated technical field
The utility model relates to a kind of heat-exchange device that is used for hot-water supply.
Background technology
What at present domestic heat-exchange device commonly used adopted is heat-exchangers of the plate type, because the heat-exchangers of the plate type flow resistance is big, in order to reduce flow resistance, take to increase runner and heat exchange area during design, the heat-exchangers of the plate type complex structure needs large-scale pressing equipment, and its price comparison costliness.
The utility model content
The purpose of this utility model is to provide the heat-exchange device that a kind of structure is small and exquisite, in light weight, thermal power is big.
The purpose of this utility model can realize by following technical measures: comprise shell-and-tube exchanger, the heat medium water water circulating pump, heat medium water inlet channel and heat medium water outlet conduit, the housing two ends correspondence of described shell-and-tube exchanger is provided with the working-medium water import and export and heat medium water is imported and exported, working-medium water is imported and exported and is communicated with the housing inner chamber, described heat medium water water circulating pump is connected to the heat medium water import of shell-and-tube exchanger through the heat medium water inlet channel, the heat medium water outlet conduit is connected in the heat medium water outlet of shell-and-tube exchanger, it is characterized in that: described housing inner chamber is provided with the bull ripple spiral coil of the above differently curved radius of one deck, bull ripple spiral coil is by its bending radius layer overlaps successively, and the two ends of all bull ripple spiral coils are imported and exported with heat medium water and communicated and be tightly connected.
The surfaces externally and internally of every pipe in the bull ripple spiral coil described in the utility model is corrugated.
Because the bull ripple spiral coil of differently curved radius is nested successively from level to level, constitute the tube side and the shell side of heat convection thus, the tube side of this uniqueness and the flow passage structure of shell side flow heating agent and working medium with very high flow-rate impulse formula in runner separately, strengthened heat convection like this, make it have very high heat transfer coefficient, volume is little, and is in light weight; Also make simultaneously dirt lose the condition of existence.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is explained.
Fig. 1 is the utility model structural representation.
Fig. 2 is a ripple helix tube shell-and-tube exchanger structural representation.
The specific embodiment
As Fig. 1, shown in Figure 2, present embodiment comprises shell-and-tube exchanger 1, heat medium water water circulating pump 2, heat medium water inlet channel 3 and heat medium water outlet conduit 4, the housing 5 two ends correspondences of shell-and-tube exchanger are provided with working-medium water and import and export 6,7 and heat medium water import and export 8,9, working-medium water is imported and exported and is communicated with the housing inner chamber, heat medium water water circulating pump 2 is connected to the heat medium water import 8 of shell-and-tube exchanger through heat medium water inlet channel 3, heat medium water outlet conduit 4 is connected in the heat medium water outlet 9 of shell-and-tube exchanger, the housing inner chamber is provided with the bull ripple spiral coil 10 of five layers of differently curved radius, every layer of bull ripple spiral coil rolls into undulatory straight tube bending radius in accordance with regulations by many surfaces externally and internallies, the number of turns, pitch and helical angle process, every layer of bull ripple spiral coil is inserted in the housing by its bending radius successively from level to level, the two ends of all bull ripple spiral coils are imported and exported with heat medium water and are communicated and be tightly connected, and constitute the tube side and the shell side of heat convection thus; The tube side of this uniqueness and the flow passage structure of shell side flow heating agent and working medium with very high flow-rate impulse formula in runner separately, strengthened heat convection greatly.The concrete course of work is that water circulating pump pumps into the high temperature heat medium water the bull ripple helix tube from boiler, housing inner chamber and working-medium water at shell heat exchanger carry out heat convection, participate in the next round circulation after the heat medium water of low temperature is got back to boiler and heated after the heat exchange again, heated working-medium water then enters the heating system heat supply by requirement of system design.
Claims (2)
1, a kind of heat-exchange device, comprise shell-and-tube exchanger, the heat medium water water circulating pump, heat medium water inlet channel and heat medium water outlet conduit, the housing two ends correspondence of described shell-and-tube exchanger is provided with the working-medium water import and export and heat medium water is imported and exported, working-medium water is imported and exported and is communicated with the housing inner chamber, described heat medium water water circulating pump is connected to the heat medium water import of shell-and-tube exchanger through the heat medium water inlet channel, the heat medium water outlet conduit is connected in the heat medium water outlet of shell-and-tube exchanger, it is characterized in that: described housing inner chamber is provided with the bull ripple spiral coil of the above differently curved radius of one deck, bull ripple spiral coil is by its bending radius layer overlaps successively, and the two ends of all bull ripple spiral coils are imported and exported with heat medium water and communicated and be tightly connected.
