Description
Technical Field
The utility model relates to a high-efficient water heater especially relates to promote device of built-in indirect heat exchanger static heat transfer power of closed container, belongs to water heater technical field.
Background
The conventional structure of the existing water heater is an indirect heat exchanger such as a coil pipe which is arranged in a water storage container and forms a heat exchange circulating system with an external heat source. When the water heater works, the heat exchange medium of the heat exchange circulating system is controlled to flow, and the water in the water storage container can be heated by means of heat generated by an external heat source. However, the water in the water storage container is relatively static in a non-water using state, and even in a using state, the water in the water storage container only has disturbance, so the heat exchanger basically can only exchange heat with the water in the water storage container through conduction, and the efficiency is low.
Disclosure of Invention
The utility model aims to provide a: to the problems existing in the prior art, the efficient water heater capable of remarkably improving the heat exchange efficiency is provided, so that the use requirement is better met.
In order to achieve the above purpose, the utility model discloses high-efficient water heater's basic technical scheme is: the heat exchanger comprises a water storage container with a water inlet and a water outlet, wherein an indirect heat exchanger which forms a heat exchange circulating system with an external heat source is arranged in the water storage container, a liquid separating cover and a liquid collecting cover are respectively arranged above and below the heat exchanger, the top of the liquid separating cover is provided with a self-circulation inlet, liquid outlets facing the heat exchanger are distributed at the lower part of the liquid separating cover, and liquid return ports facing the heat exchanger are distributed at the bottom of the liquid collecting cover and the upper part of the liquid collecting cover; the self-circulation outlet is communicated with the self-circulation inlet through a pipeline provided with a self-circulation pump.
When the self-circulating pump is not started, the utility model can perform static heating, namely, the heat source can heat the basically static water in the water storage container by the heat exchanger through the heat exchange circulation to heat the stored liquid; when the self-circulation pump is started, the water flow speed on the heat exchange surface of the heat exchanger is obviously accelerated, so that the heat exchange efficiency is effectively improved.

Detailed Description
Example one
As shown in figure 1, a water tank serving as a water storage container 1 of the efficient water heater is provided with an inner container 1-2 wrapped by an insulating layer 1-3, and the lower part and the upper part of the inner container 1-2 are respectively provided with a water inlet 1-5 and a water outlet 1-1. The middle part of the inner container 1-2 is provided with a temperature measuring port 1-4.
The inner container of the water storage container 1 is provided with a vertically arranged coil heat exchanger 2 which forms a heat exchange circulating system through a heat exchange pump P1 and a heat pump system (which can also be a fuel gas or other heat sources) serving as an external heat source 4.
A liquid separating cover 3-1 and a liquid collecting cover 3-2 are respectively arranged above and below the coil heat exchanger 2. The structure of the liquid separation cover 3-1 is shown in fig. 2 and fig. 3, and the liquid separation cover is provided with an upper conical cover 3-1.2 which is gradually enlarged downwards, the center of the top of the upper conical cover 3-1.2 is provided with an upward self-circulation inlet 3-1.1, the periphery of the lower end of the upper conical cover 3-1.2 is distributed with a liquid outlet 3-1.3 facing to a coil pipe of a coil pipe heat exchanger 2, and the self-circulation inlet 3-1.1 is communicated with the liquid outlet 3-1.3 through an interlayer or a shunt pipe. The structure of the liquid collection cover 3-2 can be analogized from that of the liquid separation cover 3-1 easily, the liquid collection cover is provided with a lower conical cover which is gradually expanded upwards, the center of the bottom of the lower conical cover is provided with a downward self-circulation outlet, and the periphery of the upper end of the lower conical cover is provided with a liquid return port facing the coil of the coil heat exchanger 2; the liquid return port is communicated with the self-circulation outlet through an interlayer or a shunt pipe. The self-circulation outlet of the liquid collection cover 3-2 is communicated to the self-circulation inlet 3-1.1 of the liquid separation cover 3-1 through a pipeline provided with a self-circulation pump P2, so that forced convection circulation is formed.
It is understood that, this embodiment both can be respectively, also can open heat exchange pump P1 simultaneously and from circulating pump P2 to have nimble heating methods, when opening heat exchange pump P1 simultaneously and from circulating pump P2, the developments rivers in water storage container 1 make the rivers speed on heat exchanger heat transfer surface obviously accelerate, thereby can effectively improve heat exchange efficiency, accelerate programming rate and hot water supply volume, and be favorable to guaranteeing that the temperature is even. Experiments show that the temperature uniformity can reach +/-0.3 ℃.
