Abstract
The utility model discloses a rapid heat exchanger. The rapid heat exchanger comprises a tube box, a barrel body, supports, a heat exchange tube bundle, a back end socket and an outer sleeve. The tube box is connected with one end of the barrel body through an equipment flange. A heating medium inlet is formed in the upper portion of the tube box, and a heating medium outlet is formed in the lower portion of the tube box. A cold medium outlet, a pressure gauge port and a safety valve port are respectively formed in the upper portion of the barrel body. A drain outlet is formed in the lower portion of the barrel body. The outer sleeve sleeves the other end of the barrel body. The other end surface of the barrel body is of an oblique surface. The back end socket is connected with the tail end of the outer sleeve. A cold medium inlet is formed in the lower portion of the outer sleeve. The rapid heat exchanger has the advantages of scientific and reasonable structure, small space occupation, large heat exchange area, long service life and good heat exchange effect.
Description
Technical field
The utility model relates to a kind of heat-exchange apparatus, relates in particular to a kind of instantaneous heat exchanger.
Background technology
In the hot water supply system of industry and civil buildings, mainly contain volumetric heat exchanger, half-volume type heat exchanger and instantaneous heat exchanger.Instantaneous heat exchanger is mostly shell-and-tube, in shell, be covered with tube bank, heat exchange amount is large, heat transfer coefficient is high, conventional instantaneous heat exchanger structure mainly comprises bobbin carriage at present, cylindrical shell, bearing, heat-exchanging tube bundle and rear head, bobbin carriage is connected by vessel flange with cylindrical shell one end, bobbin carriage top is provided with heating agent import, below is provided with heating agent outlet, cylindrical shell top is provided with refrigerant exit, gauge port and relief valve port, below is provided with sewage draining exit and refrigerant import, rear head is directly connected with cylindrical shell, refrigerant import department in cylindrical shell is provided with tilting impingement baffle, during work, water is inputted from refrigerant import, owing to being provided with impingement baffle, avoided the direct impact of heat exchanging tube bank, but now discharge is large, flow velocity is fast, although under the guiding of impingement baffle, water impact can slow down a little, but can rush at fast the heat-exchanging tube bundle of cylindrical shell, still heat exchanging tube bank has certain indirect stroke power on the one hand, easily make on the other hand current produce short-circuit condition, and exist current inhomogeneous, the shortcoming that heat transfer effect is poor, moreover this structure also exists occupation of land space large, heat exchange area utilizes inadequate shortcoming.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of scientific and reasonable for structure, take up an area that space is little, heat exchange area large, the instantaneous heat exchanger of long service life and good effect of heat exchange.
For achieving the above object, the utility model is by the following technical solutions: a kind of instantaneous heat exchanger, comprise bobbin carriage, cylindrical shell, bearing, heat-exchanging tube bundle and rear head, described bobbin carriage is connected by vessel flange with described cylindrical shell one end, described bobbin carriage top is provided with heating agent import, below is provided with heating agent outlet, described cylindrical shell top is provided with refrigerant exit, gauge port and relief valve port, below is provided with sewage draining exit, this heat exchanger also comprises outer sleeve, described outer sleeve is set on the described cylindrical shell other end, and described cylindrical shell other end is an inclined-plane, described rear head is connected with described outer sleeve end, described outer sleeve below is provided with refrigerant import.
Effective achievement of the present utility model: the utility model is scientific and reasonable for structure, the sheathed outer sleeve of the other end at cylindrical shell, not only shortened the length of cylindrical shell, reduce it and taken up an area space, and owing to having inclusion relation between outer sleeve and cylindrical shell, refrigerant import is arranged on the below of outer sleeve, take full advantage of heat exchange area, also changed the flow path of current, not only avoided outlet short circuit phenomenon, and make it greatly reduce the impulsive force to heat-exchanging tube bundle in cylindrical shell, extend the service life of heat-exchanging tube bundle, thereby extend the service life of heat exchanger; Moreover current are even, greatly improved its heat transfer effect.
In sum, the utlity model has scientific and reasonable for structure, take up an area that space is little, heat exchange area large, the feature of long service life and good effect of heat exchange.
