Abstract
A double-pipe heat exchanger comprises a protective shell and a shell pass and a tube pass which are arranged in the protective shell, wherein the shell pass and the tube pass are two standard round steel tubes with different tube diameter sizes, the tube pass is sleeved in the shell pass, and the tube pass and the shell pass are arranged in a bending manner; a cold water inlet and a hot water outlet are respectively formed at two ends of the shell pass; and a refrigerant inlet and a refrigerant outlet are respectively formed at two ends of the tube pass. The two ends of the tube pass extend out of two ends of the shell pass, and the tube pass and the shell pass are arranged in a bending manner. Two different varieties of media reversely or equidirectionally flow in the shell pass and thetube pass to achieve the heat exchange effect. The tube pass for heat exchange is enlarged in the double-pipe heat exchanger. The double-pipe heat exchanger has the advantages of simple and reasonablestructure, small volume, quick heating, low cost, small energy consumption, non-pollution, security, reliability and long service life, and can realize the full-automatic control with the heated water controlled within the range of 45 DEG C to 110 DEG C.
Description
Technical field
The utility model relates to a kind of heat exchanger, a kind of specifically double pipe heat exchanger.
Background technology
At present, the double pipe heat exchanger that uses on the market is because its complex structure, unreasonable can not make the heat energy in the heat exchanger all exchange, so the temperature of delivery port is lower, can not satisfy use at the high-temperature water in particular job place, and the power consumption height of equipment, inefficiency.
Summary of the invention
The purpose of this utility model, the deficiency that is intended to solve the problems of the technologies described above provides a kind of double pipe heat exchanger, and it is simple and reasonable, thermal efficiency height, high-temperature water can reach more than 95 ℃.
The technical scheme that the utility model adopted is: a kind of double pipe heat exchanger, form by protective case and airtight shell side and the tube side that is arranged in the protective case, shell side and tube side are the round steel pipe of two caliber size various criterions, tube side is sleeved in the shell side, both common crooked settings, be respectively equipped with cold water inlet and hot water outlet at the two ends of shell side, be respectively equipped with refrigerant inlet and refrigerant exit at the two ends of tube side.
The two ends of shell side are stretched out at the two ends of described tube side.
Described shell side and tube side are the crooked setting of shape.
Described refrigerant inlet, hot water outlet, refrigerant exit and cold water inlet are arranged on outside the protective case.
Described hot water outlet is arranged on the refrigerant arrival end, and cold water inlet is arranged on the refrigerant exit end.
The beneficial effects of the utility model are: heat exchanger is provided with a protective case, and protective case can not only protect tube side more heat energy not to be discharged to the external world; Shell side and tube side are long steel pipe, and are the crooked overlapping setting of W type, have strengthened the tube side of heat exchange; Simple in structure, volume is little, and the speed that heats is fast, and cost is low, and energy consumption is little, and is pollution-free, safe and reliable, long service life.Can realize Automatic Control, the hot water of making can be controlled in 45 ℃-110 ℃.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of double pipe heat exchanger is made up of protective case 1 and airtight shell side 2 and the tube side 3 that is arranged in the protective case 1, be that double pipe heat exchanger 8 adopts the standard pipe of two kinds of different sizes to be connected to become concentrically ringed sleeve pipe, the outside be shell side 2,3, two kinds of different mediums of tube side that inner is can be in shell side 2 and tube side 3 reverse flow or co-flow to reach the effect of heat exchange.Be respectively equipped with cold water inlet 6 and hot water outlet 7 at the two ends of shell side 2, be respectively equipped with refrigerant inlet 4 and refrigerant exit 5 at the two ends of tube side, hot water outlet 7 is arranged on refrigerant 4 ends that enter the mouth, and cold water inlet 6 is arranged on refrigerant exit 5 ends; Shell side 2 and tube side 3 are two long round steel pipe, are the shape that the bending of a plurality of W types links together, and the shell side wall by shell side 2 two ends is fixedly installed in the protective case 1.
Described tube side 3 is sleeved in the shell side 2, and the length of tube side 3 is greater than the length of shell side 2, and tube side 3 stretches out from the two ends of shell side 2.
Described refrigerant inlet 6, hot water outlet 7, refrigerant exit 5 and cold water inlet 6 are arranged on outside the protective case 1.
The refrigeration principle of general refrigeration machine, the effect of compressor is that the lower vapour pressure of pressure is shortened into the higher steam of pressure, and the volume of steam is reduced, pressure raises.Compressor sucks the working substance steam of the lower pressure that comes out from evaporimeter, make it to send into condenser after pressure raises, in condenser, be condensed into the higher liquid of pressure, after the choke valve throttling, after becoming the lower liquid of pressure, send into evaporimeter, heat absorption evaporation in evaporimeter and become the lower steam of pressure, send into the inlet of evaporimeter again, thereby finish kind of refrigeration cycle.
Heat change method of the present utility model is: when the refrigerant band of compressor 11 outlet a large amount of heat energy and entered the tube side 3 of double pipe heat exchanger 8, the cold water in the shell side 2 were reverse mobile and the heat exchange in the refrigerant is come out shell side 2 in along flowing to of refrigerant.In the process of heat exchange, refrigerant is progressively lowered the temperature along the direction that tube side 3 metal pipe internal wall flow, and water progressively heats up along the direction that shell side 2 metal tube outer walls flow.Because the pipeline of shell side 2 and tube side 3 is very long, so delivery port can obtain the water of higher temperature.Low temperature refrigerant after the heat exchange enters evaporimeter 10 by throttling arrangement, and refrigerant enters compressor 11 by evaporimeter 10 again and implements shuttling movement, constantly produces heat energy.Can obtain the hot water of different temperatures by the flow of control water.
