Abstract

Four coolers (1) are mounted on the top plate (41) of the casing (40) of a corpse storing device (4). A heat transfer member (3) for transferring cold heat of a Peltie element (21) in the cooler (1) penetrates the top plate (41) to protrude upward and can touch a corpse directly. Since a cooler (11) is arranged at the neck of the corpse, it can freeze the neck portion to prevent bad smell and filth from leaking to the outside thus storing the corpse for a long time. Three other coolers (12) are distributed to the abdomen of the corpse. This corpse storing device has high cooling efficiency and can store the corpse for a long time.

Description

Refrigeration apparatus and body storage apparatus using the same

[0 0 0 1]

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

[0 0 0 2]

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.

[0 0 0 3]

As an alternative to dry ice, various devices have been proposed to cool the body by introducing the cool air of the refrigerator into the cage. Most of them use a separate hose to introduce cold air into the tub with a rubber hose. In the case of this device, the installation position is limited by the length of the hose into which the cold air is introduced, and the hose is dragged, resulting in lack of mobility.

[0 0 0 4]

In view of this, a cocoon cooling device in which a cocoon is placed on a caster incorporating an air cooler has been proposed and disclosed in Japanese Patent Application Laid-Open No. 2000/190/1992.

[0 0 0 5]

Since the cold storage device disclosed in the above Japanese Patent Laid-Open No. 2 0 3 -1 9 0 2 3 2 uses the cold air circulation casket itself as the corpse casket, the existing casket cannot be used. Disadvantage that it is expensive because it is structured and custom-ordered There is.

[0 0 0 6]

Although the used cocoon cooler can be used again, it is not preferred because of hygiene and user concerns. Therefore, since the cold-flowing soot according to the reference invention is incinerated with the body, a custom-made soot is produced each time, which is expensive and uneconomical.

[0 0 0 7]

In addition, this structure has the disadvantage that the cooling rise is poor because the body is housed in the cold air circulation cage and placed on the cage cooling device before the cooling device is started.

[0 0 0 8]

Therefore, a martress that efficiently cools and stores the body using a thermoelectric cooling unit has been proposed and disclosed in Utility Model Registration No. 3 1 1 9 5 5 4.

[0 0 0 9]

The pineless disclosed in the above utility model registration No. 3 1 1 9 5 5 4 is to transmit the cold heat of the thermoelectric cooling unit to the cooling plate with a relatively large area so as to cool the main part of the body. It is configured. The head cooling plate is formed in a dish shape so as to receive the back of the head, and the cooling plate on which the body portion is placed is made of a wide plate so as to cover the entire body portion.

C O 0 1 0)

These cooling plates use metals with good thermal conductivity, such as copper and aluminum, but in practice, cheap aluminum is used. The most common way to process aluminum like a cold plate on the head is by the aluminum die-casting method.

[0 0 1 1]

Therefore, we made and used a cooling plate for the head by the aluminum die-casting method, and found that it was difficult to ensure the initial cooling temperature. This is because many aluminum block bodies made by the aluminum die-cast method are contained in the material. The thermal conductivity is not very good, and the contact surface between the aluminum block and the ceramic surface of the thermoelectric cooling element of the thermoelectric cooling unit is not very good. As a result, it was found that the thermal conductivity was hindered. In addition, it seems that the heat transfer surface of the cold plate is too wide, and cold energy exceeding the capacity of the thermoelectric cooling element is consumed, and the temperature of the cold plate does not drop as planned.

[0 0 1 2]

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

[0 0 1 3]

A 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.

C O 0 1 4)

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

[0 0 1 5]

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. Disclosure of the invention

A high cooling device can be provided.

[0 0 2 6]

The thermoelectric cooling element, in particular 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. Also, the Peltier element The cooling effect greatly depends on the thermal conductivity of the heat transfer member and the thermal resistance of the contact surface.

[0 0 2 7]

Since the highly heat-conductive aluminum block used in the cooling device of the present invention is formed into a Lie body by insert molding and an aluminum molded product by the die-casting method, the contact surfaces of both are in close contact, Thermal conductivity becomes good, and the cold heat of the thermoelectric cooling element can be conducted efficiently.

The results of experiments comparing the cooling efficiency of the cooling device (case storage device) of the present invention with the conventional one are shown below.

The cooling device of this application is shown in Fig. 1. The heat conduction member is a high heat conductive aluminum block body manufactured by extruding A 6063 aluminum alloy and then cutting it.卜 Aluminum alloy is integrally molded by inserter molding. The size of the heat transfer member is H 60mmXW6 OmmX L 16 Omm for the neck heat transfer member and H 35mmXW6 OmmX L 16 Omm for the body heat transfer member.

[0046]

As the Peltier element, FPHI-1 2707M (module size: 40 mm X 40 mm, DC 12 V, 6 A) manufactured by Fujitaka Co., Ltd. was used.

[0047]

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

[0048]

Fig. 10 shows the cooling capacity of the product of the present invention and the target product. Room temperature (R 1), cooling temperature of the target product (A), cooling temperature of the product of the present invention (head (B) and body part (C)) was measured temporarily. The target product has a very slow temperature drop and does not drop below 8 ° C. In contrast, the products of the present invention 5 minutes after putting the hoop, it drops rapidly to 6 ^e C. Finally, the temperature drops to zero degrees or below.

[0 0 4 9]

Figure 11 examined the relationship between room temperature and cooling capacity for the product of the present invention. Up to 60 minutes, the cooling capacity of the product of the present invention was measured temporarily at room temperature, and after that, the temperature was lowered by cooling and the relationship between the room temperature and the cooling capacity was examined. R 2 is room temperature, D is the head temperature, and E is the body temperature. D D is the difference between room temperature and head temperature (R 2− D), D E is the difference between room temperature and body temperature (R 2− E), both of which represent cooling capacity.

Since the cooling capacity of the Peltier element is the ability to reduce the temperature of the object to be cooled from room temperature to how many times, the cooling capacity can be displayed by the temperature difference. The temperature difference between the room temperature and the object to be cooled is 13 C when the target product in Fig. 10 enters a stable state (after 40 minutes), but the room temperature after 40 minutes has passed in the product of the present invention. The temperature difference between the object and the object to be cooled is 17 to 21 ° C, clearly superior to the target product. However, the target product does not drop below zero degrees, but with the product of the present invention, it can be lowered to below zero degrees, and in particular, if the neck temperature is frozen below zero degrees, a strange odor is generated from the mouth and nose. Greatly effective in preventing leakage of filth and filth.
