[0029] Combine the following Figure 1-Figure 3 The technical solution provided by the utility model is described in more detail.
[0030] Embodiment 1:
[0031] See also Figure 1 and Figure 2 As shown, the energy storage heat exchange device provided by the utility model includes a furnace body 1 and a heat exchanger located in a box body 2, a circulating medium for heating circulates in the box body 2, wherein: the medium inlet of the heat exchanger is connected to the oil supply pipe 3, and the medium outlet of the heat exchanger is connected to the oil return pipe 4; a heating part 7, a heat storage structure 5 and a coil 6 are arranged in the furnace body 1, the heating part 7 is electrically connected to an external power supply and can generate heat when powered on, the heat storage structure 5 is in contact with the heating part 7 for storing heat; the coil 6 passes through the heat storage structure 5, and the two ends of the coil 6 are respectively connected to the oil supply pipe 3 and the oil return pipe 4.
[0032] Among them, see Figure 1 As shown, the circulating medium in the box 2 is used to be led out through pipes to the building for heating. Figure 1 In the middle box 2, from Figure 1 The viewing angle is blocked by the side wall of the box body 2. The heat exchanger is an existing commonly used tubular heat exchanger, and its structure is not described again.
[0033] The heat storage structure 5 is a block structure made of heat storage material. The heat storage material can be a honeycomb ceramic heat storage body or a common adsorption heat storage material in the prior art.
[0034] See also Figure 1 and Figure 2 As shown, the coil 6 is in contact with the heat storage structure 5. The heat stored in the heat storage structure 5 heats the heat transfer oil in the coil 6. After being heated, the heat transfer oil enters the heat exchanger through the oil supply pipe 3 under the action of the pump body 11, and exchanges heat with the circulating medium in the box 2. After the circulating medium is heated, it is led out to the building for heating. After the heat exchange, the temperature of the heat transfer oil drops and re-enters the coil 6 through the return oil pipe 4 for heat exchange.
[0035] In the heat exchange device of this embodiment, the municipal power supply can be powered on to the heating part 7 during off-peak hours, and the heating part 7 generates heat, and stores the heat in the heat storage structure 5. The heat storage structure 5 heats the coil 6 passing through it, and the heat transfer oil in the coil 6 is heated and then increases in temperature, and flows from the oil supply pipe 3 into the heat exchanger to exchange heat with the circulating medium in the box 2. After the heat transfer oil exchanges heat, it flows back into the coil 6 from the return oil pipe 4 to be heated again. The heat transfer oil is in indirect contact with the heat storage structure 5 through the coil 6, which improves the heat transfer rate. The thermal conductivity of the heat transfer oil is higher than that of air, which reduces heat energy loss, improves the heat transfer efficiency, and thus improves the heating effect of the integrated heating system.
[0036] As an alternative embodiment, see Figure 2 and Figure 3As shown, the coil 6 includes a horizontal section 61 and a curved section 62 . The horizontal section 61 passes through the heat storage structure 5 , and the curved section 62 connects adjacent horizontal sections 61 .
[0037] The coil 6 of the above structure is inserted into the heat storage structure 5 , which can improve the heat utilization rate of the heat storage structure 5 , reduce heat loss, and transfer more heat in the heat storage structure 5 to the heat transfer oil in the coil 6 .
[0038] As an alternative embodiment, see Figure 2 As shown, the heat storage structure 5 is provided with first openings 51 penetrating through the opposite side walls thereof. The first openings 51 are arranged in a matrix-like interval arrangement, and the coil 6 passes through the first openings 51 .
[0039] Specifically, the horizontal section 61 of the coil 6 passes through the first opening 51, and the heat in the heat storage structure 5 is transferred to the coil 6 in the first opening 51, and then transferred to the heat transfer oil, thereby improving the heat utilization rate and facilitating the heat storage structure 5 to uniformly heat different positions of the coil 6.
[0040] As an alternative embodiment, see Figure 2 As shown, the heating part 7 includes more than two, and all the heating parts 7 pass through the heat storage structure 5 and are arranged in a matrix. Figure 2 The heat storage structure 5 is provided with second openings 52 penetrating through the opposite side walls thereof. The second openings 52 are arranged in a matrix-like interval, and the heating part 7 passes through the second openings 52 .
[0041] The heating part 7 (heating tube) passes through the second opening 52. When the heating tube is powered on and generates heat, it can transfer heat to the heat storage structure 5. The heat storage structure 5 stores heat, which improves the heat utilization rate and makes it easier for the heating part 7 to transfer heat to different parts of the heat storage structure 5, thereby improving the uniformity of heat in the heat storage structure 5.
[0042] As an alternative embodiment, see Figure 2 As shown, regulating valves 12 are provided at both ends of the coil 6 for regulating the flow of the heat transfer oil flowing into or out of the heat exchanger.
[0043] The flow rate of the heat transfer oil entering the heat exchanger can be adjusted by the regulating valve 12, thereby adjusting the temperature of the heat transfer medium in the box 2 to achieve the purpose of temperature control.
[0044] As an alternative embodiment, see Figure 1 As shown, the energy storage heat exchange device also includes an oil replenishment tank 8, an oil feeding pipe 9 and an oil replenishment pipe 10, wherein: the oil replenishment tank 8 is connected to the oil return pipe 4 through the oil feeding pipe 9, the outlet of the oil feeding pipe 9 is located above the oil replenishment tank 8, or is connected to the upper part of the oil replenishment tank 8, the oil replenishment tank 8 is connected to the oil supply pipe 3 through the oil replenishment pipe 10, and the port of the oil replenishment pipe 10 is connected to the bottom of the oil replenishment tank 8.
[0045] The above structure enables the energy storage heat exchange device to adapt to temperature changes. Specifically, the heat transfer oil in the energy storage heat exchange device expands in summer or when the temperature is high, and the heat transfer oil can flow back from the oil feeding pipe 9 to the oil replenishing tank 8 for storage. The heat transfer oil in the energy storage heat exchange device shrinks in winter or when the temperature is low, and the heat transfer oil in the oil replenishing tank 8 can flow back from the oil replenishing pipe 10 to the oil supply pipe 3 to replenish the amount of heat transfer oil in the oil supply pipe 3.
[0046] The above structure can adjust the amount of heat transfer oil in the device under different ambient temperatures, thereby ensuring stable operation of the entire device.
[0047] As an optional implementation, the side walls of the furnace body 1 are made of heat-insulating material, thereby reducing internal heat loss and improving heat utilization.
[0048] As an optional embodiment, the heat storage structure 5 is wrapped with a vermiculite board. As a heat-insulating material board, the vermiculite board has excellent heat-insulating performance, which can lock the temperature in the furnace body 1 and prevent heat loss.
[0049] Embodiment 2:
[0050] This embodiment provides an integrated heating system, including a box 2 and the above-mentioned energy storage heat exchange device. In this embodiment, the heat transfer oil is in indirect contact with the heat storage structure 5 through the coil 6, which improves the heat exchange rate. The thermal conductivity of the heat transfer oil is higher than that of the air, which reduces the heat energy loss, improves the heat exchange efficiency, and thus improves the heating effect of the integrated heating system.
