Problems solved by technology

[0004] However, if the above-mentioned existing heat storage device is used, since the heat is stored / taken out of the heat storage material through the heat exchanger 3, there is a shortcoming of low utilization rate of the heat storage agent.
Especially in devices using heat pumps as heat sources, since heat is stored by indirect heat exchange, the efficiency is very low

Embodiment 1

[0031] figure 1 It is a structural schematic diagram of the heat storage device in the first embodiment of the present invention.

[0032] Such as figure 1 As mentioned in , the heat storage component 8 is composed of a profile 10 with a primary fluid flow path 9 , and one side or both sides of the profile 10 is provided with a heat storage body 11 , and the heat storage body 11 contains a heat storage agent 2 . The flow path plate 13 has the secondary fluid flow path 12 and is clamped by the raised portion 14, and the profiles 10 and the flow path plate 13 are stacked in sequence. The heat accumulator 11 is arranged to be in close contact with the heat accumulator component 8 and the flow path plate 13 , and an end plate 15 is provided on the outermost side thereof, and the end plate 15 is fastened by fasteners 16 such as screws.

[0033] The operation and function of the thermal storage device having the above-mentioned configuration will be described below.

Embodiment 2

[0037] figure 2 It is a schematic structural view of the heat storage device in the second embodiment of the present invention.

[0038] exist figure 2 Among them, the profile 10 in the heat storage component 8 is made of aluminum extruded profile, and the outer surface of which is in contact with the heat storage body 11 composed of a heat storage agent 2 such as sodium acetate trihydrate is provided with a resin or the like. Anti-corrosion surface film17.

[0039]The working conditions and functions of the thermal storage device with the above-mentioned configuration will be described below.

[0040] Firstly, although the regenerator 11 made of regenerator 2 such as sodium acetate trihydrate will be in contact with both sides of the aluminum extruded profile 10, since there are anti-corrosion coatings 17 on both sides of the profile 10, It can prevent the heat storage agent 2 from directly contacting with aluminum, and prevent aluminum ions from dissolving into the heat...

Embodiment 3

[0043] image 3 It is a schematic structural view of the heat storage device in the third embodiment of the present invention.

[0044] exist image 3 Among them, the flow path plate 13 is made of copper plate, and the outer surface in contact with the profile 10 and the heat storage agent 2 is provided with an anti-corrosion film 17 by means of chrome plating or the like.

[0045] The working conditions and functions of the thermal storage device with the above-mentioned configuration will be described below.

[0046] When the heat storage component 8 and the flow path plate 13 are laminated, the surface of the flow path plate 13 contacts the heat storage agent 2 and the raised portion 14 of the profile 10 . Since the flow path plate 13 is made of copper plate with excellent thermal conductivity, heat can be well transferred from the heat storage agent 2 to the secondary fluid. Moreover, since the anti-corrosion film 17 is provided on the surface of the flow path plate 13,...

Abstract

The present invention provides a heat storage device of high efficiency by improving utilization factor of a heat storage agent. This heat storage device is constituted by successively stacking a heat storage panel 8 having a primary-side fluid flow channel and a flow channel flat plate having a secondary-side fluid flow channel through a heat reservoir, and the heat reservoir, the heat storage panel and the flow channel flat plate are closely kept into contact with each other. The heat reservoir is held between the heat storage panel having the primary-side fluid flow channel and the flow channel flat plate having the secondary-side fluid flow channel and stacked, thus the heat storage agent can be packed with high concentration, the heat of a heat source can be directly transferred to the heat reservoir, and the heat can be taken in and out to the heat storage agent with high efficiency.

Description

technical field [0001] The invention relates to a heat storage device used in equipment such as heating and heating. Background technique [0002] In the existing heat storage device, a heat exchanger is generally installed in the heat storage tank filled with heat storage agent, and the circulating water heated by the heat source is sent to the heat exchanger in the heat storage tank by a circulating pump. Heat storage is carried out in the heat agent (the heat storage agent can change state between liquid and solid when the temperature changes). When heating, make the water flowing in from the water inlet pipe flow through the heat exchanger, take heat from the heat storage agent, and then supply hot water through the hot water pipe (for an example, refer to Japanese Patent Laid-Open Publication No. 2003-232563). [0003] Figure 10 shows the existing heat storage device described in the above-mentioned reference. Such as Figure 10 As shown in , this heat storage device...
