Abstract
The utility model provides a coil pipe heat exchanger. The outer part of a casing of the coil pipe heat exchanger is connected with a heating medium inlet, a heating medium outlet, a heated medium inlet, and a heated medium outlet. A coil pipe bundle and a central pipe are arranged in the casing. The central pipe is divided into a pipe pass and a pipe pass by a partition plate, and the periphery of the central pipe is provided with a choke coil. The utility model is suitable for being used for supplying heat for a building and supplying hot water. The utility model is also suitable for being used in other heat transfer systems.
Description
Technical field
The utility model belongs to a kind of heat-exchange apparatus, is suitable for using in building and heating, hot water supply and other heat transfer systems.
Background technology
The coil heat exchanger that generally uses in heating source one side, has import and outlet two tubes vertically to be arranged in the housing of heat exchanger at present, causes connected coil pipe tube bank can only be arranged in a side, can not be covered with the whole section of heat exchanger.When heated medium was flowed through heat exchanger shell pass, most did not directly wash away coil pipe tube bank, and space little through resistance, that do not have heat-exchanging tube bundle is passed through, and caused that flow velocity is low, heat transfer coefficient is little.Simultaneously, owing to wasted a part of space, under the identical situation of heat exchange effect, existing coil heat exchanger needs bigger volume, has increased manufacturing cost.
Summary of the invention
The purpose of this utility model provides a kind of coil pipe is restrained and is covered with the whole section of heat exchanger, strengthens the heated medium flow velocity, improves the coil heat exchanger of heat transfer coefficient.
The purpose of this utility model can realize by following technical measures:
Housing is connected with the heat medium inlet outward, in heat medium outlet, heated medium inlet, heated medium outlet, the housing coil pipe tube bank, central tube is arranged, and central tube has dividing plate to be divided into tube side and tube side.
The purpose of this utility model also can realize by following technical measures:
Choking coil is arranged around the central tube.
The utility model has been owing to adopted center tube structure, and is provided with choking coil, can make heated medium all effectively wash away the coil pipe tube bank, improved the heat transfer coefficient of heat exchanger, under identical heat-transfer effect situation, the physical dimension that can dwindle heat exchanger tube reduces manufacturing cost.
Description of drawings
Fig. 1 is the schematic diagram that is provided with the embodiment of plane clapboard in the central tube of the present utility model;
Fig. 2 is the schematic diagram that is provided with the embodiment of curved surface dividing plate in the central tube of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further.
This coil heat exchanger is made of heated medium inlet 1, housing 2, coil pipe tube bank 3, choking coil 4, central tube 5, heat medium inlet 6, heated medium outlet 7, dividing plate 8, tube side 9, tube side 10, heat medium outlet 11.The tube side 9 that heat medium is entered in the central tube 5 by heat medium inlet 6, the coil pipe of flowing through comes together in tube side 10 after restraining 3 heat releases, flows out through heat medium outlet 11.Heated medium is entered in the housing 2 by heated medium inlet 1, the coil pipe tube bank 3 of flowing through and arranging around central tube 5, and the heat absorption back is flowed out by heated medium outlet 7.For making heated medium all effectively wash away the coil pipe tube bank, around central tube 5, be provided with tubular choking coil 4.
Claims (2)
1. coil heat exchanger, the outer heat medium inlet (6) that is connected with of housing (2), coil pipe tube bank (3), central tube (5) are arranged in heat medium outlet (11), heated medium inlet (1), heated medium outlet (7), the housing (2), it is characterized in that central tube (5) has dividing plate (8) to be divided into tube side (9) and tube side (10).
