[0002] With the gradual reduction of non-renewable resources such as coal, oil, and natural gas, people are paying more and more attention to energy conservation and full utilization. At present, the commonly used heating systems are mostly single heat source heating, such as electric heating, coal-fired heating, etc.

[0003] Phase change heat storage heating does not require additional laying of heat or gas pipelines. It takes advantage of the difference in peak and valley electricity prices. At night, low-priced valley electricity is fully utilized to store heat in the phase change unit through an electric heating device. During the day, the heat stored in the unit is released for heating as needed, saving heating operating costs.

[0004] However, traditional phase change heat storage heating equipment is fixed indoors and connected to heating or geothermal pipes during use, which makes the use process inflexible and needs to be improved. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a phase change heat storage heating device with flexible use effect.

[0018] In a preferred example, the utility model can be further configured as follows: the heat exchanger body is tilted, with the lower end close to the inside of the chassis and the upper end protruding outward.

[0019] In a preferred example, the utility model can be further configured as follows: the coils are provided with multiple layers, and the coils on adjacent sides are arranged in a staggered manner.

DETAILED DESCRIPTION

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0036] like Figure 1 , Figure 2 As shown, a phase change heat storage heating device includes a chassis 1, a water tank 2, a water pump 3, a heater 4, a phase change heat exchanger 5, a first two-way valve 6, a heat exchange fan 7, a second two-way valve 8 and a third two-way valve 9.

[0037] like Figure 1 , Figure 2 As shown, the chassis 1 is vertically arranged on the ground, and a roller 11 is arranged at the lower end of the chassis 1, so as to facilitate moving the heating device to different use positions and improve the use flexibility. The water tank 2 is arranged at the upper end of the chassis 1, the water pump 3 is connected to the water tank 2, the heater 4 is connected to the outlet end of the water pump 3, and the phase change heat exchanger 5 is arranged side by side below the water tank 2 and connected to the outlet end of the heater 4.

[0038] like Figure 1 , Figure 2As shown, the first two-way valve 6 is connected to the outlet end of the phase change heat exchanger 5, and the heat exchange fan 7 is connected to the outlet end of the first two-way valve 6 and the water tank 2. The second two-way valve 8 is connected to the outlet end of the first two-way valve 6 and the water tank 2, and the third two-way valve 9 is connected to the heater 4 and the inlet end of the second two-way valve 8.

[0039] The working process of the equipment is divided into the following three stages:

[0040] like Figure 3 As shown, the first stage is the energy storage stage:

[0041] The circulation order is: water tank 2 → water pump 3 → heater 4 → phase change heat exchanger 5 → first two-way valve 6 → second two-way valve 8 → water tank 2.

[0042] This cycle utilizes valley electricity to heat water first, and then utilizes water to bring heat to the phase change heat exchanger 55 to increase the temperature of the phase change material and bring energy to the phase change material for storage.

[0043] like Figure 4 As shown, the second stage is the energy release stage:

[0044] The circulation sequence is: water tank 2 → water pump 3 → heater 4 → phase change heat exchanger 5 → first two-way valve 6 → negative heat exchange fan 7 → water tank 2.

[0045] This cycle uses water to take heat out of the phase change material, heats the water, transfers the heat to the heat exchange fan 7, and realizes the heating operation. In this stage, the heater 4 is turned off to minimize the power consumption.

[0046] like Figure 5 As shown, the third stage is the mixing stage:

[0047] The circulation order is: water tank 2→water pump 3→heater 4→phase change heat exchanger 5→first two-way valve 6→heat exchange fan 7→water tank 2 and water tank 2→water pump 3→heater 4→third two-way valve 9→heat exchange fan 7→water tank 2.

[0048] This cycle has two paths working at the same time and converging into the heat exchange fan 7, which can not only store energy in the phase change heat exchanger 5, but also directly operate the heat exchange fan 7 for heating, thereby reducing electricity costs as much as possible, responding to the country's peak-shaving and valley-filling policy, and meeting the use needs of the heat exchange fan 7.

[0049] At the same time, by providing a heat exchange fan 7, instead of the traditional direct connection to heating or floor heating, direct heating of the heating equipment is achieved, which makes it easier to move the heating equipment to different use locations and improves the flexibility of use.

[0050] like Figure 6 , Figure 7As shown, the heat exchange fan 7 includes a heat exchanger body 71 and a fan body 72. The heat exchanger body 71 is located above the fan body 72. The heat exchanger body 71 is tilted, and the lower end is close to the inside of the chassis 1, and the upper end protrudes outward, so as to increase the air inlet area, reduce wind resistance, realize the conversion and transmission of thermal energy resources, and improve the heating effect of the heating equipment.

[0051] like Figure 7 As shown, the heat exchanger body 71 includes a shell 73, a coil 74, a water inlet head 75 and a water outlet head 76. The lower end of the shell 73 is open and connected to the fan body 72, the coil 74 is arranged in a serpentine shape in the shell 73, and the water inlet head 75 and the water outlet head 76 are both located on the same side of the shell 73 and are respectively connected to the two ends of the coil 74.

[0052] like Figure 7 As shown, the coil 74 is provided with multiple layers, and the coils 74 on the adjacent sides are arranged in a staggered manner. A plurality of heat sinks 77 are provided in the outer shell 73. The coil 74 passes through the heat sink 77 to increase the storage capacity of the water source and fully realize energy storage and release. It is also used to fully transfer heat or fully absorb heat to improve the effect of energy storage and release.

[0053] like Figure 7 , Figure 8 As shown, the coil 74 includes a plurality of straight tubes 741 that cross the heat sink 77 and a plurality of elbows 742 that connect the straight tubes 741. Both ends of the elbows 742 are provided with bamboo joint inserts 743. Both ends of the straight tubes 741 are provided with bamboo joint holes 744 for inserting the bamboo joint inserts 743.

[0054] Since the heat sink 77 is completely mounted and fixed on the coil 74, a split coil 74 is provided, and the straight tube 741 is first passed through the heat sink 77 to achieve the connection between the coil 74 and the heat sink 77, and then the bamboo joint plug 743 on the elbow 742 is quickly inserted into the bamboo joint plug hole 744 on the straight tube 741 to achieve rapid assembly of the coil 74 and the heat sink 77, thereby achieving rapid and convenient assembly of the entire heat exchanger body 71 and ensuring rapid production of the heat exchanger body 71.

[0055] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed.
