Background technology
Water source heat pump water heater is to have utilized earth surface or shallow-layer water source; Like the solar energy that absorbs in underground water, river and the lake and geothermal energy and the low-grade heat source that forms; Adopt heat pump principle,, carry out the hot-water heating system of power conversion through a spot of high-order electric energy input.Because its energy-conserving and environment-protective characteristic is classified as the regenerative resource category by country.
Existing hot water storage tank operation principle with heating function commonly used is as shown in Figure 1, and it mainly comprises parts such as casing 2, heat(ing) coil 4, water supplement port 1, hot water outlet 7, heating agent inlet 9, heating agent outlet 8.Concrete operation principle is: utilize the working medium that gets into from the heating agent inlet, and through the mode of managing interior heat convection, tube wall heat conduction and managing outer heat convection, the water heating that water tank is inner, heated hot water is flowed out by hot water outlet.Because this type of is managed outer heat convection and belong to heat transfer free convection in conducting heat, its heat exchange resistance is maximum, is the bottleneck place of improving the coil pipe heat exchange property, so improve the enhancing that its convection transfer rate is very beneficial for whole heat exchange property.In fact, can not to form effective circulation be to cause one of lower reason of its coefficient of heat transfer to the outer heat convection of above-mentioned pipe.
The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence, provide a kind of and can make the water in the water tank form good convection circulation, thereby improve the outer convection transfer rate of pipe, the water resource heat pump that reaches the augmentation of heat transfer purpose is used heating water tank.
The technical scheme of the utility model technology is achieved in that a kind of water resource heat pump uses heating water tank; Comprise casing, the water supplement port that is communicated with casing respectively and hot water outlet and be arranged on the heat(ing) coil in the casing; Said heat(ing) coil two ends are respectively heating agent inlet and heating agent outlet; It is characterized in that: the inner tube wall that up/down perforation is set in said casing; Said inner tube wall is divided into annular heat exchanger channels zone and center with box house, and said heat(ing) coil is arranged in the annular heat exchanger channels zone along the outside wall surface of inner tube wall.
The described water resource heat pump of the utility model is used heating water tank, and its said inner tube wall is the structure that barrel dliameter is reduced to both ends by the middle part gradually.
The described water resource heat pump of the utility model is used heating water tank, and the heating agent outlet and the heating agent inlet of its said heat(ing) coil place casing outside.
The described water resource heat pump of the utility model is used heating water tank, and its said hot water outlet places casing top, and said water supplement port places lower box.
The utility model is divided into annular heat exchanger channels zone and center through inner tube wall is set with box house in casing, make to have formed good convection circulation in the casing, thereby well improved the outer convection transfer rate of pipe, has reached the purpose of augmentation of heat transfer.The utility model manufacturing is simple, convenient, stable and reliable operation.
Description of drawings
Fig. 1 is existing heating water tank structural representation.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the cross-sectional view of the utility model.
Mark among the figure: 1 is water supplement port, and 2 is casing, and 3 is annular heat exchanger channels zone, and 4 is heat(ing) coil, and 5 is inner tube wall, and 6 is the center, and 7 is hot water outlet, and 8 are the heating agent outlet, and 9 are the heating agent inlet.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model technology is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figures 2 and 3; A kind of water resource heat pump is used heating water tank; Comprise casing 2, the water supplement port 1 that is communicated with casing 2 respectively and hot water outlet 7 and be arranged on the heat(ing) coil 4 in the casing 2, said heat(ing) coil 4 two ends are respectively heating agent inlet 9 and heating agent outlet 8, and said hot water outlet 7 places casing 2 tops; Said water supplement port 1 places casing 2 bottoms, and said heating agent outlet and heating agent inlet place casing 2 outsides.
Wherein, The inner tube wall 5 of up/down perforation is set in said casing 2; The structure that said inner tube wall 5 is reduced to both ends by the middle part for barrel dliameter gradually; Said inner tube wall 5 is divided into annular heat exchanger channels zone 3 and center 6 with casing 2 inside, and said heat(ing) coil 4 is arranged in the annular heat exchanger channels zone 3 along the outside wall surface of inner tube wall 5.
The utility model operation principle: at first; The high temperature heating agent that is made by water source heat pump units gets into heat(ing) coil through the heating agent inlet; Through managing the mode of interior heat convection, tube wall heat conduction and the outer heat convection of pipe; In annular heat exchanger channels zone water is heated, the heating agent that is cooled flows back to water source heat pump units through the heating agent outlet.Heated hot water constantly flow out from the top of annular heat exchanger channels, and the lower hot water of temperature flows into annular heat exchanger channels zone by the center through the regional bottom of annular heat exchanger channels once more because density is less.So form good thermal convection current circulation, strengthened the heat convection between the water in heat(ing) coil and the casing.When needs hot water is supplied,, replenish cold water by water supplement port simultaneously by the hot water outlet hot-water supply.
To sum up, under the effect of the utility model, can realize the good heat exchange of coil pipe heating system, help reducing the condensation temperature of source pump, improve heat pump coefficient of performance COP.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
