Description

  The present invention relates to a heat storage member, a heating device, a heating device for an automobile, a pan, and a heating cooker.

Various techniques using the heat stored in the heat storage material are known. For example, solar heat, factory exhaust heat or the like can be stored as heat energy in a heat storage medium such as water or air, and can be taken out and used as necessary.
In the situation of heat storage and heat dissipation, there are gaps in place and time, so means for transporting heat and heat insulation technology for storing heat for a long time were important.

  Conventional heat storage materials are broadly classified into sensible heat storage materials that use temperature changes of substances, latent heat storage materials that use phase changes of substances, and chemical heat storage materials that use chemical reaction heat.

  However, these heat storage materials have the following problems. In other words, since the sensible heat storage material and the latent heat storage material release heat to the outside over time, it is difficult to maintain the heat storage state for a long time even if they have a heat insulation mechanism. In addition, after heat release, in order to store the chemical heat storage material again, processing at a high temperature is necessary, and it has been difficult to repeatedly use it.

In recent years, livestock heat dissipation materials to which livestock heat dissipation titanium oxide having a composition of Ti ₃ O ₅ is applied have been proposed (Patent Document 1). The animal heat radiation material described in Patent Document 1 can maintain a heat storage state as long as it does not receive an external stimulus. Moreover, since the heat storage material can be easily stored again after heat radiation, it can be used repeatedly.

<First Embodiment>
[Heat storage material]
Hereinafter, the heat storage member 1 is demonstrated as an example of the heat storage member to which 1st Embodiment of this invention is applied. FIG. 1 is a plan view showing the heat storage member 1. FIG. 2 is a cross-sectional view of FIG.

  As shown in FIGS. 1 and 2, the heat storage member 1 includes ceramic particles 10, a fluid medium 15, and a container 20 filled with the ceramic particles 10 and the fluid medium 15. The container 20 has one end 20a closed, and the other end 20b is provided with a pressurizing unit 5 configured to stimulate the ceramic particles 10. In this specification, the pressurizing unit 5 corresponds to the stimulating unit in the claims.

  The heat storage member 1 uses the Pascal principle to release the latently stored heat by causing a phase transition of the ceramic particles 10 filled in the heat storage member 1.

(Ceramic particles)
The ceramic particles 10 release heat by solid-solid phase transition.
The ceramic particles 10 exhibit a first solid phase and a second solid phase having a higher free energy than the first solid phase.
The first solid phase undergoes a phase transition to the second solid phase by heat, light or current. On the other hand, the second solid phase dissipates heat by pressure or light stimulation and makes a phase transition to the first solid phase. In the present embodiment, attention is paid to the property that the ceramic particles 10 undergo a phase transition from the first solid phase to the second solid phase by heat, dissipate heat by stimulation by pressure, and undergo a phase transition from the second solid phase to the first solid phase. Designed.

  The second solid phase of the ceramic particles 10 is preferably stable at 60 ° C. or lower. In other words, the ceramic particles 10 preferably do not undergo phase transition from the second solid phase to the first solid phase even at 60 ° C. or lower. The heat storage member 1 using such ceramic particles 10 can maintain a heat storage state even at 60 ° C. or less. Moreover, since the heat insulation apparatus which heat-retains the thermal storage member 1 can be simplified or abbreviate | omitted, the apparatus in various uses can be reduced in size.

  In the heat storage member 1, the heat radiation temperature on the outer surface of the container 20 is preferably 60 ° C. or higher. When the heat release temperature is 60 ° C. or higher, the space can be efficiently warmed when the heat storage member 1 is applied to a heating device or an automotive heating device described later. Moreover, when applying the thermal storage member 1 to a pan or a heating cooker, the food can be heated or kept in a range of 60 to 65 ° C., which is a temperature at which a person can feel the food deliciously. Although it depends on the specific heat [J / (kg · ° C.)] of the forming material of the container 20 and the environment in which the heat storage member 1 is used, the heat radiation temperature on the outer surface of the container 20 is 10 ° C. to 15 ° C. than the target temperature of the object. It is good to adjust the amount of livestock heat radiation of the heat storage member 1 so that it may become high temperature.

The amount of stored and released heat of the heat storage member 1 can be adjusted by the filling amount of the ceramic particles 10. For example, the filling amount [kg] of the ceramic particles 10 when the heat radiation temperature on the outer surface of the container 20 is a predetermined temperature is calculated by the equation (1).
_{M x C x ((T 1} + ΔT) -T 2) = M y C y (T 2 -T 1) (1)
Each value of Formula (1) represents the following.
M _x : mass of the ceramic particles 10 [kg]
M _y: a container 20 Weight [kg]
C _x : Specific heat of the forming material of the ceramic particles 10 [J / (kg · ° C.)]
C _y : Specific heat of forming material of container 20 [J / (kg · ° C.)]
T ₁ : Initial temperature [° C.] on the outer surface of the container 20 or the ceramic particle 10
T ₂ : heat radiation temperature [° C.] on the outer surface of the container 20 or the ceramic particles 10
ΔT: rising temperature of ceramic particles 10 [° C.]

  In the present embodiment, the mass of the container 20 may be directly measured before the ceramic particles 10 are filled, or may be calculated by multiplying the volume of the container 20 obtained in advance by a specific gravity.

Table 1 shows the filling amount of the ceramic particles 10 when reinforced ceramic is used as the material for forming the container 20. _Cy was 1 [J / (kg · ° C.)], T ₁ was 10 [° C.], T ₂ was 75 [° C.], and ΔT was 80 [° C.].

Reinforced ceramics is a generic term for alumina reinforced ceramics obtained by firing a mixture of porcelain clay and aluminum oxide (Al ₂ O ₃ ) at a high temperature, and fiber reinforced ceramics obtained by combining silicon carbide and carbon fibers. Alumina reinforced ceramics are used as a material for forming reinforced porcelain. Examples of the reinforced porcelain include New Neohard manufactured by Aiki Kyodo Co., Ltd. or Ogiso Re-OGISO. Examples of fiber reinforced ceramics include fiber reinforced ceramics manufactured by Coors Tech Co., Ltd.

The wall thickness of the container 20 shown in FIGS. 1 and 2 was 1.5 [mm]. In addition, the diameter R of the circle when approximated by a circle that is the smallest when the container 20 is viewed in plan (hereinafter referred to as “spiral diameter R”) was set to 250 [mm]. The inner diameter of the container 20 shown in Table 1 is the inner diameter of the container 20 that does not include the pressurizing unit 5. The inner diameter of the container 20, when filled with ceramic particles 10 in advance experimentally container 20, and a diameter when T ₂ has reached more than 75 ° C..

  Table 1 shows the filling amount of the ceramic particles 10 when New Neohard made by Aiki Kyodo Co., Ltd. is used as the alumina reinforced ceramic, and the fiber reinforced ceramic of Coors Tech Co., Ltd. is used as the fiber reinforced ceramic.

The ceramic particle 10 is not particularly limited as long as it has the above-described properties, and examples thereof include livestock heat radiation titanium oxide having a composition of Ti ₃ O ₅ . Livestock heat-dissipating titanium oxide having a composition of Ti ₃ O ₅ exhibits a β phase as a first solid phase and a λ phase as a second solid phase.

  Unlike the material used in the conventional chemical heat storage material, the composition of the ceramic particles 10 does not change when radiating heat. Therefore, the heat storage member 1 using the ceramic particles 10 can easily store heat even after heat radiation as compared with a conventional chemical heat storage material, and can be used repeatedly.

(Fluid medium)
As shown in FIG. 2, a fluid medium 15 is filled between the ceramic particles 10 and between the ceramic particles 10 and the inner wall of the container 20. The fluid medium 15 propagates the pressure applied to the pressurizing unit 5 from the other end 20b toward the one end 20a. The fluid medium 15 applies isotropic pressure to the ceramic particles 10. The heat released from the ceramic particles 10 propagates to the container 20 through the fluid medium 15. At this time, the volume of the fluid medium 15 expands due to the heat released by the ceramic particles 10. Thereby, the heat storage member 1 of the present embodiment can more efficiently apply pressure to the ceramic particles 10.

  The fluid medium 15 is preferably a liquid at room temperature. In addition, when the heat storage member 1 is heated to cause phase transition from the first solid phase to the second solid phase, the fluid medium 15 is preferably excellent in heat resistance. Specific examples of such a fluid medium include silicon oil, ester oil, and phenyl ether oil.

(container)
The container 20 encloses the ceramic particles 10 and the fluid medium 15 and facilitates efficient propagation of pressure to the ceramic particles 10. Further, the container 20 heats an object to be heated that is in contact with the outer surface of the container 20 by using heat released from the ceramic particles 10.

  As shown in FIGS. 1 and 2, the container 20 has a tubular shape and has a spiral shape as a whole. Since the amount of ceramic particles 10 occupying the flat area defined by the outer periphery of the heat storage member 1 increases as the space between the spirals decreases, the heat storage member 1 increases the amount of heat released from the animal. Moreover, it is known that the ceramic which is a material for forming the ceramic particles 10 has a large heat capacity. Since the container 20 has a spiral shape, the walls of the container 20 having a small heat capacity are present at regular intervals. Therefore, it is possible to suppress an increase in the heat capacity of the heat storage member 1. Therefore, the ceramic particles 10 can be efficiently heated, and the heat released by the ceramic particles 10 can be efficiently extracted.

  When the heat storage member 1 is viewed in plan, the shape defined by the outermost periphery of the spiral shape of the heat storage member 1 is substantially circular.

  Moreover, it is preferable that the cross-sectional area of the internal space of the container 20 is constant. When the cross-sectional area is constant, the pressure applied to the pressure unit 5 can be propagated uniformly, and the heat released by the ceramic particles 10 can be taken out uniformly.

  Examples of the material for forming the container 20 include stainless steel, life iron, iron containing steel, aluminum, aluminum alloy, copper, titanium, titanium alloy, and reinforced ceramics from the viewpoint of heat transfer, heat resistance, and mechanical strength. As a forming material of the container 20, reinforced ceramic is preferable.

  For example, when the forming material of the container 20 is a reinforced ceramic, the container 20 can be manufactured by sintering what was formed into a desired shape using the reinforced ceramic.

  The pressurizing unit 5 has a cylindrical shape, and the cross section of the internal space of the pressurizing unit 5 is substantially circular.

FIG. 3 is an enlarged schematic cross-sectional view of the pressurizing unit 5. As shown in FIG. 3, the heat storage member 1 has a pressing portion 7 that is inserted into the pressing portion 5.
The pressing unit 7 prevents the ceramic particles 10 and the fluid medium 15 from flowing out of the container 20 and presses the ceramic particles 10 by being pressed from the outside. The length of the portion of the pressing unit 7 inserted into the pressing unit 5 is such that the pressing unit 7 does not detach from the pressing unit 5 even if the volume of the fluid medium 15 expands due to the heat released by the ceramic particles 10. Is set.

  As a forming material of the pressing portion 7, for example, stainless steel or iron is preferable from the viewpoint of mechanical strength.

The magnitude of the pressure applied to the pressurizing unit 5 is determined according to the pressure at which the ceramic particles 10 undergo phase transition from the second solid phase to the first solid phase and the cross-sectional area S of the internal space of the pressurizing unit 5.
A smaller cross-sectional area S of the internal space of the pressurizing unit 5 is preferable because less pressure is required. Specifically, the cross-sectional area S of the internal space of the pressurizing unit 5 is preferably 25 mm ² or less, and more preferably 1 mm ² or less.
The inner diameter of the pressure unit 5 may be different from the inner diameter of the container 20.

  As a method of pressurizing the pressurizing unit 5, for example, a method of hitting the pressing unit 7 with a hammer and pressing it can be mentioned.

  Hereinafter, the principle that the heat storage member 1 dissipates heat will be described. First, by pressing the pressing portion 7, the ceramic particles 10 and the fluid medium 15 existing in the pressing portion 5 are pressed by the pressing portion 7. The pressure applied to the pressurizing unit 5 propagates through the internal space of the container 20 from the other end 20b toward the one end 20a, and theoretically all the ceramic particles 10 are pressurized. On the other hand, the pressurized ceramic particles 10 dissipate heat and heat the fluid medium 15 therearound. Thereby, the fluid medium 15 is thermally expanded, and the internal pressure of the container 20 is increased. Theoretically, all ceramic particles 10 are pressurized by the increase in the internal pressure of the container 20. Thus, the heat storage member 1 dissipates heat.

  The ceramic particles 10 inside the heat storage member 1 can maintain the state of the second solid phase that is in the heat storage state until the pressurizing unit 5 is pressurized. And it can dissipate by pressurizing the pressurizing part 5 and can make a phase transition from the second solid phase to the first solid phase. That is, since heat can be radiated when the pressurizing unit 5 is pressurized, the heat storage member 1 can radiate heat at an arbitrary timing. From the above, according to the present embodiment, a heat storage member capable of livestock heat dissipation is provided.

[Heating device]
Hereinafter, the heating apparatus 100 will be described as an example of a heating apparatus to which the heat storage member 1 is applied. FIG. 4 is a schematic cross-sectional view showing the heating device 100.

  As shown in FIG. 4, the heating device 100 includes a burner (heater) 101, a heat storage member 1, a stimulation unit 103, a heat transport unit 107, and a blowout port 111. The heat transport means 107 includes an intake passage 109 and a blower fan 110.

  Gas is supplied to the burner 101, and the flame H obtained by burning the gas releases heat to the intake air A1. The intake passage 109 is provided with a blower fan 110 through which intake air A1 flows. The blower fan 110 transports (blows) the heat released by the burner 101 as warm air W1.

  The heat storage member 1 is provided in the middle of the intake passage 109. The warm air W <b> 1 descends the intake passage 109 and releases heat from the heat storage member 1. The heat storage member 1 receives heat from the burner 101 (or warm air W1) and stores heat.

  The stimulating means 103 pressurizes the ceramic particles 10 through the pressurizing part 5 (see FIG. 1) of the heat storage member 1 and releases the heat stored in the heat storage member 1. The hot air W1 sent out from the burner 101, the hot air W2 sent out from the heat storage member 1, and the intake air A2 merge in the intake passage 109 and are sent out indoors as hot air W3 from the outlet 111.

  In the conventional heating apparatus, when the intake air is not sufficiently heated, such as when the burner is started or when the outside air temperature is low, it takes time until the warm air is sent out. On the other hand, in the heating device 100 of one embodiment of the present invention, the heat storage member 1 that has received heat from the burner 101 and stored heat can be radiated by the stimulation means 103. Therefore, the time until warm air is sent out can be shortened compared to the conventional case.

  Moreover, in the heating apparatus 100, when the heat storage member 1 is used even when the burner 101 is not used, warm air can be sent out. That is, even when the burner 101 cannot be used due to a power failure or the like, the heat storage member 1 can be used as a spare heat source.

[Automotive heating system]
Hereinafter, an automotive heating device 200 will be described as an example of an automotive heating device to which the heat storage member 1 is applied. FIG. 5 is a schematic diagram showing an automotive heating device 200.

  As shown in FIG. 5, the automotive heating device 200 includes an automotive engine (drive source) 201, a heat storage member 1, a stimulation unit 203, a heater core 205, and a heat transport unit 207. The heat transport means 207 includes an intake passage 209, a blower fan 210, and a heat transfer pipe 211.

The engine 201 is connected to the heater core 205 via the flow path 217. A liquid that cools the engine 201 flows through the flow path 217. A water pump 218 that flows liquid to the engine 201 and the heater core 205 is provided in the middle of the flow path 217. The water pump 218 is rotated by the power of the engine 201. The exhaust heat of the engine is released to the liquid flowing around the engine 201.
The engine 201 is connected to a pipe 225 that transports the exhaust gas E3 generated by the engine 201.

  The heater core 205 is provided in the intake passage 209. Heated liquid is supplied to the heater core 205 via the flow path 217. The heated liquid releases heat to the intake air A4 sent into the room (vehicle interior) during the heating operation. The intake passage 209 is provided with a blower fan 210 through which intake air A4 flows. The blower fan 210 transports the heat released by the heater core 205 as warm air W4.

  The heat storage member 1 is provided around a pipe 225 that transports the exhaust gas E3. The heat storage member 1 receives heat from the engine 201 (or exhaust gas E3) and stores heat.

  The stimulating means 203 pressurizes the ceramic particles 10 via the pressurizing part 5 (see FIG. 1) of the heat storage member 1 and releases the heat stored in the heat storage member 1. The heat transfer pipe 211 connected to the heat storage member 1 transports the heat released by the heat storage member 1 to the intake passage 209 as warm air W5. Warm air W4 sent from the heater core 205 and W5 sent from the heat storage member 1 merge in the intake passage 209 and are sent to the room as warm air W6.

  In a conventional automotive heating device, when the liquid is not sufficiently heated, such as when the engine is started or when the outside air temperature is low, it takes time until the warm air is delivered. On the other hand, in the automotive heating device 200 according to one aspect of the present invention, the heat storage member 1 that has accumulated heat by receiving the exhaust heat of the engine 201 can be dissipated by the stimulating means 203, so that the warm air is sent out. Time can be shortened compared with the past.

[pot]
Hereinafter, the pan 300 will be described as an example of a pan to which the heat storage member 1 is applied. FIG. 6 is a perspective view showing the pan 300. As shown in FIG. 6, the pan 300 includes a pan body 301, a heat storage member 1 provided on the bottom wall 301 a of the pan body 301, a stimulation means 303, and a lid 305.

  The heat storage member 1 is welded to the bottom wall 301a. The pan 300 is a direct fire type pan, and the heat storage member 1 receives heat from the direct fire and stores heat.

  The stimulating means 303 pressurizes the ceramic particles 10 via the pressurizing part 5 (see FIG. 1) of the heat storage member 1 to release the heat stored in the heat storage member 1. The heat released from the heat storage member 1 is released to the bottom wall 301a, and the article to be heated T1 placed in the pan 300 is heated or kept warm.

  In the conventional direct-fire type pan, when the heating in the direct fire is stopped, the heat of the pan body 301 is released to the surrounding air. Further, the heat of the article to be heated T1 is also released to the surrounding air directly or via the pan body 301. On the other hand, in the pan 300 of one embodiment of the present invention, the heat storage member 1 that has received heat from an open fire and stored heat can be radiated by the stimulation means 303. Therefore, the pot 300 can be heated to heat or keep the object to be heated T1 even after the heating in the direct fire is stopped.

[Heating cooker]
Hereinafter, the cooking device 400 will be described as an example of a pan to which the heat storage member 1 is applied. The heating cooker 400 is in contact with the cooking utensil 410 and heats or keeps the object to be heated T2 placed in the cooking utensil 410. FIG. 7 is a perspective view showing the heating cooker 400. As shown in FIG. 7, the cooking device 400 includes a heat source 401 that is a driving source of the cooking device 400, the heat storage member 1, and a stimulation unit 403.

  The heat storage member 1 stores heat from the heat source 401. The position where the heat storage member 1 is provided is not particularly limited as long as it can receive heat from the heat source 401.

  The stimulating means 403 pressurizes the ceramic particles 10 via the pressurizing part 5 (see FIG. 1) of the heat storage member 1 and releases the heat stored in the heat storage member 1. The heat released from the heat storage member 1 is released to the cooking utensil 410, and the article to be heated T2 placed in the cooking utensil 410 is heated or kept warm.

  In the pan of the conventional cooking device, when the heating by the heat source 401 is stopped, the heat of the cooking utensil 410 is released to the surrounding air. Further, the heat of the object to be heated T2 is also released to the surrounding air directly or through the cooking utensil 410. On the other hand, in the heating cooker 400 of one embodiment of the present invention, the heat storage member 1 that has received and stored heat from an open fire can be dissipated by the stimulating means 403, so that cooking is performed even after heating by the heat source 401 is stopped. The tool 410 can be heated to heat or keep the object T2 to be heated.

Second Embodiment
[Heat storage material]
Hereinafter, the heat storage member 2 is demonstrated as an example of the heat storage member to which 2nd Embodiment of this invention is applied. FIG. 8 is a perspective view showing the heat storage member 2. 9 is a cross-sectional view taken along line IX-IX in FIG. The second embodiment is partially in common with the first embodiment. The difference is that the ceramic particles 10 are designed by paying attention to the property that the heat is released by the stimulation by light and the phase transitions from the second solid phase to the first solid phase. Therefore, as shown in FIGS. 8 and 9, the irradiation part 6 of the heat storage member 2 has a light-transmissive member 9 so that the ceramic particles 10 can be irradiated with light.

  In the heat storage member 2, the container 21 has a disk shape. The irradiation unit 6 is provided along the diameter direction of the heat storage member when the heat storage member 2 is viewed in plan.

The light applied to the ceramic particles 10 is not particularly limited as long as the ceramic particles 10 can undergo phase transition. When the ceramic particles 10 are livestock heat radiation titanium oxide, ultraviolet light to infrared light (laser light with a wavelength of 355 nm to 1064 nm) can be used as the irradiation light. Moreover, when the ceramic particle 10 is livestock heat radiation titanium oxide, the light quantity of the light to irradiate is the range of 0.5 * 100mJcm ^<-2 > * pulse ^{< -1} > -15 * 100mJcm ^<-2 > * pulse- ¹ .

  Hereinafter, the principle that the heat storage member 2 radiates heat will be described. First, light is irradiated toward the internal space of the heat storage member 2 through the translucent member 9. Since the ceramic particles 10 in the vicinity of the translucent member 9 are directly irradiated with light, the phase transition from the second solid phase to the first solid phase releases the stored heat. Due to this heat, the fluid medium thermally expands, so that the internal pressure of the heat storage member 2 increases. Due to this pressure, the ceramic particles 10 that are not directly irradiated with light undergo phase transition from the second solid phase to the first solid phase, and the stored heat is released. As the internal pressure rises and the heat dissipation of the ceramic particles 10 occurs in a chain, the ceramic particles 10 of the entire heat storage member 2 undergo a phase transition from the second solid phase to the first solid phase, and the stored heat is released. In this way, the heat storage member 2 releases the stored heat.

  The ceramic particles 10 in the heat storage member 2 can maintain the state of the second solid phase, which is a heat storage state, for a period until light is irradiated. Then, the stored heat can be released by phase transition from the second solid phase to the first solid phase by irradiation of light. That is, the stored heat can be released when the heat storage member 2 is irradiated with light. Therefore, the heat storage member 2 can dissipate heat at an arbitrary timing. From the above, according to the present embodiment, a heat storage member capable of radiating heat is provided as in the first embodiment.

Note that one embodiment of the present invention is not limited to the above embodiment.
For example, in the first embodiment, an example in which the heat storage member 1 is filled with the fluid medium 15 is shown, but the fluid medium 15 may not be filled. In that case, the ceramic particles 10 may be filled so as to be in contact with the adjacent ceramic particles 10. When the fluid medium 15 is not filled in the heat storage member, the configuration of the heat storage member becomes simpler, and thus the reliability of the heat storage member can be improved.

  Moreover, in 1st Embodiment, when the heat storage member 1 was planarly viewed, the shape prescribed | regulated by the outer periphery of the heat storage member 1 showed the substantially circular shape, However, A shape is not limited to this. For example, the shape defined by the outer periphery of the heat storage member 1 may be a triangle, a rectangle, a polygon, or the like.

In the first embodiment, an example in which the container 20 has a spiral shape has been described. However, the pitch of the spiral may be constant or random.
