Description

  The present invention relates to a cooling device that transmits the cold heat of a thermoelectric cooling unit to a cooled object by heat conduction, directly cools the cooled object, and keeps the corpse for a long time using this cooling device. The present invention relates to a corpse storage device that prevents the corpse.

  Dry ice is usually used to keep the carcass body cold. However, since dry ice vaporizes into carbon dioxide, its use is restricted from the viewpoint of global warming.

  As an alternative to dry ice, various devices have been proposed in which cold air from a refrigerator is introduced into a cage to keep the body cool. Most of them are of a type in which cold air is introduced into a bag by a rubber hose from a separate refrigeration apparatus. In the case of this apparatus, the installation position is limited by the length of the hose into which the cold air is introduced, and the hose is dragged.

In view of this, there has been proposed a cocoon cooling device in which a cocoon is placed on a caster incorporating an air cooler, and is disclosed in Japanese Patent Application Laid-Open No. 2003-190232.
JP 2003-190232 A

  Since the cold storage device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2003-190232 uses the cold air circulation cage itself as a dead body cage, it has a special structure in which the existing cage cannot be used. There is a disadvantage of becoming expensive due to reasons such as.

  Although the used cocoon cooler can be used again, it is not preferable from the viewpoint of hygiene and user's feelings. Therefore, since the cold-air circulation soot of the reference invention is incinerated together with the body, a custom-made soot is produced each time, which is expensive and uneconomical.

  In addition, this structure has a drawback in that the rise of cooling is poor because the cooling device is started after the body is accommodated in the cold air circulation cage and placed on the basket cooling device.

Accordingly, a mattress that efficiently cools and stores a body using a thermoelectric cooling unit has been proposed and disclosed in Japanese Utility Model Registration No. 3119554.
Utility Model Registration No. 3119554

  The mattress disclosed in the above-mentioned utility model registration No. 3119554 is configured to transmit the cooling heat of the thermoelectric cooling unit to a cooling plate having a relatively large area to cool the main part of the body. The cooling plate of the head is formed in a dish shape so as to receive the back of the head, and the cooling plate on which the body part is placed uses a wide plate material so as to cover the entire body part.

  These cooling plates use metals with good thermal conductivity, for example, copper and aluminum, but in practice, inexpensive aluminum is used. The most common method for processing aluminum like a cooling plate on the head is by an aluminum die casting method.

  Then, the head cooling plate was made and used by the aluminum die casting method, but it was found that it was difficult to secure the initial cooling temperature. This is because the aluminum block body made by the aluminum die-casting method has many fine bubbles in the material, and the thermal conductivity is not so good, and the heat absorption side of the aluminum block body and the thermoelectric cooling element of the thermoelectric cooling unit It was proved that the thermal conductivity was hindered due to the poor adhesion of the contact surface with the ceramic surface. In addition, it is considered that the heat transfer surface of the cooling plate is too wide, and cold energy exceeding the capacity of the thermoelectric cooling element is consumed, so that the temperature of the cooling plate does not decrease as planned.

  A first object of the present invention is to provide a cooling device with high cooling efficiency that conducts the cooling heat of a thermoelectric cooling element of a thermoelectric cooling unit directly to an object to be cooled at a low cost.

  The second object of the present invention is to provide a mortuary storage device having a high cooling efficiency and capable of storing a corpse for a long period of time at a low cost.

  A third object of the present invention is to provide a body storage device that can be coupled to or dissociated from a cooling device while the body is housed in a conventional bag.

  A fourth object of the present invention is to provide a body storage device that can be used as it is as a body storage device for funerals.

  The cooling device of the present invention includes a thermoelectric cooling unit having a thermoelectric cooling element, and a heat transfer member for conducting cold heat of the thermoelectron cooling element to an object to be cooled, the heat transfer member being a thermoelectric cooling element. A highly heat-conductive aluminum block body having a contact surface that is in close contact with the heat-absorbing surface and a heat-transfer surface that is in direct contact with the object to be cooled, and a highly heat-conductive aluminum block body that is integrally molded to surround the heat-conductive aluminum block body It consists of an aluminum molded product having an enlarged heat transfer surface that is in direct contact with an object.

  High thermal conductivity aluminum is high purity aluminum having a purity of 99% or more or a high thermal conductivity aluminum alloy. Since high-purity aluminum has extremely high thermal conductivity, it can be used as the thermal conductive member of the present invention. As the high thermal conductivity aluminum alloy, 2000 series to 7000 series aluminum alloys can be used, but from the viewpoint of workability, 6000 series aluminum alloys are most suitable.

  In order to form a block body of high thermal conductivity aluminum, a machining method such as an extrusion method or a cutting method is used. The 6000 series aluminum alloy contains Si and Mg, and has excellent strength and corrosion resistance and good extrusion moldability. Therefore, if it is cut after extrusion, the block body can be manufactured efficiently and inexpensively. .

  The aluminum molded product is molded into a desired shape by a die casting method using a die cast aluminum alloy. As a die-cast aluminum alloy, an AD alloy is most commonly used, but an HT alloy having a high thermal conductivity is most preferably used.

  The high thermal conductivity aluminum block body is integrally formed with an aluminum molded product by insert molding by insert molding. The contact surface between the aluminum block body having high thermal conductivity and the aluminum molded product is brought into close contact with the insert molding, and the thermal conductivity is improved.

  The thermoelectric cooling element of the thermoelectric cooling unit has a terminal connected to an AC power source via an AC-DC converter. Therefore, this thermoelectric cooling unit can be driven using a domestic AC power supply.

  The body storage device of the present invention includes at least one cooling device described above. And the said cooling device is hold | maintained between the board | substrate and the top plate, and the heat-transfer member which consists of a high heat conductive aluminum block body which has a heat-transfer surface, and the aluminum molded product which has an expansion heat-transfer surface penetrates a top plate, protrudes upwards, and a dead body It has the shape which mounts.

  As a preferred embodiment, the body storage device of the present invention includes at least two cooling devices described above, and the heat transfer member of one of the cooling devices is at least one other at the position where the neck of the body is placed. The heat transfer member of the above cooling device is disposed at a position where the body part of the body is placed. As a more preferable form, 2 to 4 cooling devices arranged in the body part are dispersedly arranged in the main part of the body part.

  An example of the thermoelectric cooling element is a Peltier element.

  The cooling device of the present invention includes a highly heat conductive aluminum block body having a contact surface in close contact with a heat absorbing surface of a thermoelectric cooling element and a heat transfer surface in direct contact with an object to be cooled, and the high heat conductive aluminum block. Since it has a heat transfer member made of an aluminum molded product that has an expanded heat transfer surface that is integrally formed so as to surround the body and that is in direct contact with the object to be cooled, the high thermal conductivity aluminum block body with high thermal conductivity is a thermoelectron. The cooling element efficiently absorbs the cooling energy, and the cooling energy is transmitted to the aluminum molded product having an enlarged heat transfer surface surrounding the high thermal conductivity aluminum block body, so that a cooling device with high cooling efficiency can be provided.

  The thermoelectric cooling element, particularly the Peltier element, absorbs the heat of the object to be cooled corresponding to the area of the endothermic surface and cools the object to be cooled. Therefore, if a heat transfer member that is too larger than the cooling surface of the Peltier element is connected, the temperature of the heat transfer member, that is, the temperature of the object to be cooled cannot be lowered sufficiently. In addition, the cooling effect of the Peltier element is greatly affected by the thermal conductivity of the heat transfer member and the thermal resistance of the contact surface.

  Since the high thermal conductivity aluminum block used in the cooling device of the present invention is integrally formed by die casting with an aluminum molded product by insert molding, the contact surfaces of both are in close contact and good thermal conductivity is achieved. Thus, the cold heat of the thermoelectric cooling element can be conducted efficiently.

  Since the aluminum molded product used in the cooling device of the present invention is molded by the die casting method, a heat transfer member having an arbitrary shape can be molded easily at low cost.

  Since the corpse storage device of the present invention includes at least one cooling device described above, the corpse can be stored for a long period of time with good cooling efficiency.

  The cooling device for the body storage device of the present invention is a heat transfer member that is held between a housing substrate and a top plate, and is composed of a high heat conductive aluminum block having a heat transfer surface and an aluminum molded body having an enlarged heat transfer surface. Since it has a shape in which the body is placed by projecting upward through the body, the body can be directly placed on the heat transfer member and efficiently cooled.

  Since the heat transfer member of the body storage device of the present invention protrudes upward through the top plate, a through hole corresponding to the position and size of the heat transfer member is cut in advance on the bottom surface of the conventional cage. When the body is stored in the bag and then placed on the top plate, the heat transfer member protruding from the top plate can directly contact the body and cool the body. That is, the body and the cooling device can be brought into contact with and separated from the body while the body is stored in the cage.

  The body storage device of the present invention includes at least two or more of the above cooling devices, and the heat transfer member of one of the cooling devices is disposed at a position where the neck of the body is placed, and the neck of the body is below zero degrees. The body can be stored for a long period of time because it can be cooled, and the odor and filth emanating from the organ can be blocked at the neck and prevented from being emitted to the outside.

  Furthermore, by dispersing and arranging 2 to 4 cooling members having a relatively small heat transfer area in the main part of the body part of the body, the cooling efficiency of each cooling device is increased, and the part of the body that is susceptible to decay is kept at a lower temperature. It can be cooled to prevent decay of the body.

The following is a result of an experiment comparing the cooling efficiency of the cooling device (body storage device) of the present invention with that of the conventional one.
The cooling device of the present application is shown in FIG. 1, and the heat conducting member is made of an aluminum alloy of A6063, which is formed by extruding and then cutting, using an HT-1 die cast aluminum alloy. Integrally molded by insert molding. The size of the heat conduction member is H60 mm × W60 mm × L160 mm for the neck heat transfer member, and H35 mm × W60 mm × L160 mm for the body heat transfer member.

  As the Peltier element, FPH1-12707M (module size: 40 mm × 40 mm, DC12V, 6A) manufactured by Fujitaka Co., Ltd. was used.

  The same cooling device was used for the target product, and the heat conducting member was molded by a die casting method using only an HT-1 die casting aluminum alloy. The size of the heat conducting member is the same as that of the present invention.

  FIG. 10 shows the cooling capacity of the product of this application and the target product. Room temperature (R1), the cooling temperature of the target product (A), and the cooling temperature of the product of this application (head (B) and body part (C)) over time. Measured. In the target product, the temperature drops very slowly and does not drop below 8 ° C. On the other hand, in the product of the present application, it drops rapidly to close to 6 ° C. in 5 minutes after switching on. Finally, the temperature drops to zero degrees or below.

  FIG. 11 examined the relationship between room temperature and cooling capacity for the product of the present application. Up to 60 minutes, the cooling capacity of the present product was measured over time at room temperature, and after that, the cooling was turned on to lower the room temperature, and the relationship between the room temperature and the cooling capacity was examined. R2 is room temperature, D is the head temperature, and E is the body temperature. DD is the difference between the room temperature and the head temperature (R2-D), DE is the difference between the room temperature and the body temperature (R2-E), and both represent the cooling capacity.

In the target product of FIG. 10, the temperature difference between the room temperature and the object to be cooled is 13 ° C. when the stable state is reached (after 40 minutes), but in this product, the temperature difference between the room temperature and the object to be cooled after 40 minutes has passed. The temperature difference is clearly better than the target product at 17-21 ° C. In addition, although it does not drop below zero degrees in the target product, it can be lowered to below zero degrees in the product of this application, especially if the neck temperature is frozen below zero degrees, the generation of strange odors from the mouth and nose and the contamination Greatly effective in preventing leakage.

  The body preservation apparatus 4 includes a cover 7, but when using a ready-made bag, the cover 7 is removed. A through-hole is previously opened at a position corresponding to the position of the four cooling devices 1 on the lower surface of the basket. Then, the cover 7 is removed, and the cage containing the body 8 is placed on the chassis 4. The heat transfer members 3 of the four cooling devices 1 penetrate through the through-holes of the cage and directly contact the body. And if the power supply of the cooling device 1 is turned on, the cold heat of the Peltier element 21 will be transmitted to the body via the heat transfer member 3, and the body will be cooled. If the kite is lifted when it comes out, the cooling device 1 will naturally come off the kite, and the kite can move to the hearse as it is.

  The cooling device of the present invention can also be used as a frozen storage device for fresh food such as seafood.
