The specific embodiment
The utility model such as Fig. 1, Fig. 2, shown in Figure 3, comprise heat supply import 4, heat supply outlet 6, cooling water inlet 7 and hot water outlet 1, it is characterized in that: comprise the heating tube 2 more than two and two, be communicated with by communicating pipe 8 between the heating tube 2, be inserted with endothermic tube 3 in the heating tube 2; Heat supply import 4 and heat supply outlet 6 are connected on the heating tube 2, and cooling water inlet 7 and hot water outlet 1 are connected on the heating tube 2 or are connected on communicating pipe 8 (sees Fig. 4) in addition, and cooling water inlet 7 and hot water outlet 1 are communicated with the two ends of endothermic tube 3 respectively; Heat supply import 4 constitutes heating hot water directed flow passage with heating tube 2, communicating pipe 8, heat supply outlet 6, cooling water inlet 7 constitutes bathing water directed flow passage with endothermic tube 3, hot water outlet 1, bathing water directed flow passage is opposite generally with heating hot water directed flow channel direction, constitutes the counter-flow heat exchange structure.So-called bathing water directed flow passage is opposite generally with heating hot water directed flow channel direction, is meant that the flow direction of bathing water in endothermic tube 3 is opposite with flow direction in whole heat exchanger most of the direction opposite or whole directions of hot water in heating tube 2, outside the endothermic tube 3 that heat.Most of direction on the contrary as shown in Figure 1, except the endothermic tubes 3 in the heating tube 2 topmost and bottom be the baffling, remaining is a rightabout formation adverse current.Topmost and bottom the endothermic tubes 3 in the heating tube 2 are in order effectively to utilize the space in the heating tube 2, to increase the flow process of endothermic tube 3 for the purpose of baffling, and the increase heat-exchange time can certainly design and help counterflow configuration.And Fig. 5, heat exchange mode shown in Figure 6 are full counterflow configuration.The utility model heat exchange mode can mainly be the counter-flow heat exchange structure, also can all be the counter-flow heat exchange structure.
Can design a end (seeing Fig. 1, Fig. 2) communicating pipe 8 of the present utility model at heating tube 2, and adjacent next communicating pipe design is at the other end of heating tube, in order to support and firm heating tube 2,, can between heating tube 2, be connected with support member 5 in addition simultaneously also for attractive in appearance.Between support member 5 and the heating tube 2 is obstructed, only plays and supports and firm effect.
The utility model is owing to be the counter-flow heat exchange structure, so the utility model can not installed air bleeding valve.But for exhaust better also can be installed air bleeding valve.Air bleeding valve also can freely assemble according to the installation site, is promptly installing with the heat exchanger junction, and the method that this kind installed air bleeding valve is a known technology.
The utility model is in order to increase the flow process of endothermic tube 3, and described endothermic tube 3 can be helical structure.Can be double joint or many in order to increase heat exchange amount endothermic tube 3 of the present utility model.
The utility model can be designed to heating tube 2 double (bilayer) structure in order to improve heat exchange efficiency, to be beneficial to heat radiation on fore-and-aft direction.In order to warm oneself better and to obtain hot water, in whole heating tube 2, only in the part heating tube, be inserted with endothermic tube 3 and be used for heat absorption, another part does not insert endothermic tube and does heating and use.For heating tube is two-row structure, the socket in the two-row structure can be gone into endothermic tube and is used to obtain running water hot water, and another row does not insert endothermic tube and is directly used in heating.For heating tube is single row configuration, only inserts an endothermic tube in the part heating tube therein and is used for heat absorption, and another part does not insert endothermic tube and does heating and use.
The utility model can have more multiple embodiment, and scheme described in the utility model is not limited among the present embodiment.
When the utility model used, heat supply import 4 was connected with heat supplying pipeline (as the heating supply pipeline) respectively with heat supply outlet 6, and cooling water inlet 7 connects running water pipe, and hot water outlet 1 connects the bathing water valve.Heating hot water is entered in the heating tube 2 by heat supply import 4, forms at heating tube 2 with in communicating pipe 8 and flows, and flows back to the heating supply pipeline by heat supply outlet 6.Cold running water enters endothermic tube 3 by cooling water inlet 7, flows in endothermic tube 3, by the tube wall heat absorption of endothermic tube 3, with the heating in flowing of cold running water, flows out the running water of heat from hot water outlet 1.
