FIG. 7 is an internal view seen from the reference numeral 6B-6B shown in FIG.

As shown in FIGS. 1 and 2, an endothermic corpse cooling apparatus 100 according to an embodiment of the present invention includes a heat transfer member 110, a mat (dedicated futon) 120, and the like as an example of an object to be cooled. An endothermic cooling mechanism CL that cools the corpse, an erection table 160, a lid portion 180 that covers the upper portion of the erection table 160, and an ozone generator 170 provided at a corner of the erection table 160 are provided.
The erection table 160 has a width of 500 mm to 700 mm, a depth of 400 mm to 500 mm, and a height of 70 mm to 120 mm.
The lid portion 180 has a width of 500 mm to 700 mm, a depth of 400 mm to 500 mm, and a height of 130 mm to 170 mm.
The mat 120 has a width of 500 mm to 700 mm, a depth of 400 mm to 500 mm, and a height of 30 mm to 70 mm.

The heat transfer member 110 includes a first heat transfer member 110A that extends in the horizontal direction and contacts the abdomen of the corpse, and a second heat transfer member 110B that extends in the horizontal direction and contacts the lower abdomen of the corpse. Composed. As for the first heat transfer member 110A, for a large dog, the first heat transfer member 110A contacts either the chest or the abdomen, and the second heat transfer member 110B contacts the lower abdomen.
When the corpse is actually placed on the refuge table 160, the mat 120 is placed on the refuge table 160 and the corpse is placed on the mat 120.

  In the mat 120, insertion holes 121A and 121B through which the first heat transfer member 110A and the second heat transfer member 110B are inserted are disposed at positions corresponding to the first heat transfer member 110A and the second heat transfer member 110B. In addition, the mat 120 has a square corner and the ozone generator insertion hole 122 is disposed at a position corresponding to the ozone generator 170.

  The interval from the first heat transfer member 110A to the second heat transfer member 110B is 80 mm to 120 mm (more preferably 95 mm to 105 mm), and a corpse such as a small animal is placed on the refuge table 160. Thus, the first heat transfer member 110A cools the abdomen of the corpse, and the second heat transfer member 110B cools the lower abdomen of the corpse. As a result, the internal organs of the corpse can be efficiently cooled at a pinpoint, and the aging of the corpse (damage due to corruption) can be delayed. In particular, since the internal organs of the animal tend to rot, by cooling the abdomen and the lower abdomen, the internal organs of the cadaver can be efficiently cooled pinpointed, and the aging of the corpse (damage due to rot) can be delayed.

  Among these, the erection table 160 includes a top plate 161 and a side plate 162 provided below the top plate 161. In addition, a plurality of legs 163 are provided below (on the back surface) of the erection table 160.

As shown in FIGS. 4 to 5B, the abdomen and lower abdomen endothermic cooling mechanisms CL of the endothermic cadaver cooling apparatus 100 include a heat transfer member 110 formed of an aluminum alloy, and a thermoelectric cooling unit. As a Peltier unit 130, a heat sink 140, and a heat radiating intake fan 150.
Among these, the heat transfer member 110 is configured to contact and support the dead body from below.

  Specifically, the heat transfer member 110 includes a first heat transfer member 110A and a second heat transfer member 110B. The first heat transfer member 110A and the second heat transfer member 110B have a width of 40 mm to 50 mm, a depth of 180 mm to 210 mm, and a height of 50 mm to 90 mm.

  Then, the first heat transfer member 110A and the second heat transfer member 110B are fitted into the insertion holes 121A and 121B disposed in the mat 120 (see FIGS. 1 and 2). Moreover, the ozone generator 170 is provided in the ozone generator insertion hole 122 disposed at the corner of the mat 120 (see FIGS. 1 and 2).

The height of the heat transfer member 110 is greater than the depth of the insertion holes 121A and 121B, and the difference between the height of the heat transfer member 110 and the depth of the insertion holes 121A and 121B is within 3 mm to 60 mm. That is, in a state where the heat transfer member 110 is fitted in the insertion holes 121A and 121B, the height at which the heat transfer member 110 protrudes from the mat 120 is within 3 mm to 60 mm. Thereby, in a state where the heat transfer member 110 is fitted in the insertion holes 121A and 121B, the degree of the heat transfer member 110 protruding to the mat 120 becomes too large, and the first heat transfer member 110A and the second heat transfer member It is possible to prevent a corpse such as a large animal placed on 110B from bending into a U shape.
The Peltier unit 130 has a Peltier element 131 as a thermoelectric cooling element, and is disposed on the top plate 161.
The heat absorption side of the Peltier unit 130 is in contact with the lower end surface of the heat transfer member 110 without a gap.

Here, silicone grease or the like may be applied to lower the thermal resistance so that air does not enter between the heat absorption side surface of the Peltier unit 130 and the lower end surface of the heat transfer member 110.
Thereby, the adhesiveness between the heat absorption side surface of the Peltier unit 130 and the lower end surface of the heat transfer member 110 is improved, and heat conduction is improved.
The heat sink 140 is disposed below the Peltier unit 130 and is in surface contact with the heat generation side of the Peltier unit 130.

  The heat-dissipating intake fan 150 is disposed below the heat sink 140, sucks air that is in contact with the heat sink 140 above the heat-dissipating intake fan 150, and discharges it to the inside of the lower side plate 162. Is configured to release.

In this embodiment, the heat transfer member 110 has a contact portion 111 that extends in the horizontal direction and contacts the corpse, and a support portion 112 that extends downward from the contact portion 111 and is formed in a T shape. Has been.
Further, the width W1 of the upper portion 112a of the support portion 112 in the T-shaped front view is formed wider than the width W2 of the lower portion 112b of the support portion 112.

  That is, an inclined portion 112c in which the side surface of the support portion 112 is inclined with respect to the extending direction (vertical direction) of the support portion 112 so as to gradually become wider as it goes upward is formed on the contact portion side of the support portion 112. Has been.

As a result, the heat of the corpse is first temporarily stored in the contact portion 111 of the heat transfer member 110, and in particular, the conduction path when conducting from the end side of the contact portion 111 to the lower end of the support portion 112 is shortened.
As a result, the heat of the corpse can be efficiently and smoothly conducted to sufficiently enhance the cooling effect.
Furthermore, the rigidity of the heat transfer member 110 is also increased.
As a result, even when the weight of the corpse is large, it can be cooled while being supported.

In other words, it is not necessary to cool the corpse from the abdomen side, lower abdomen side, neck side, etc. with dry ice, and the internal organs of the corpse are efficiently pinpointed from the lower abdomen side of the corpse to change the corpse over time (Damage due to corruption) can be delayed, and in some cases, the nose and ears of the corpse do not need to be filled with cotton.
In addition, as for the thickness of the contact part 111 of the heat-transfer member 110 of T character front view, in order to acquire sufficient heat storage effect, it is desirable that it is about 8 mm-15 mm.
On the other hand, if it is too thick, the weight increases.
In the present embodiment, the heat sink 140 includes a heat sink base portion 141 and a plurality of fin portions 142.
Among these, the heat sink base portion 141 is in contact with the heat generation side of the Peltier unit 130.
The fin portion 142 protrudes downward from the heat sink base portion 141 and extends in the horizontal direction.
In the present embodiment, as an example, 18 fin portions 142 are formed.
Further, the extending direction D (longitudinal direction) of the fin portion 142 is also the width direction of the endothermic corpse cooling apparatus 100.

Further, as shown in FIG. 5A, the heat radiating intake fan 150 is disposed below the fin portion 142 and at the center of the extending range of the fin portion 142 in the horizontal direction.
Thus, an air flow is generated from both end sides of the fin portion 142 toward the center along the extending direction D of the fin portion 142 with the heat radiating intake fan 150 as the center.
As a result, heat can be released without any bias in either one of the extending directions D of the fin portions 142.
That is, heat can be efficiently released compared to the case where the heat radiating intake fan 150 is installed at a position biased in the extending direction D of the fin portion 142.
Further, the intake air amount and the exhaust air amount become the same, and the efficiency of heat exchange increases.
Further, in this embodiment, as shown in FIGS. 4 and 5B, the thickness of the heat sink base portion 141 is provided to be 6 mm or more.

As a result, the heat generated from the heat generating side of the Peltier unit 130 is first temporarily stored in the heat sink base part 141, then conducted to the fin part 142 and radiated from the fin part 142.
As a result, it is possible to avoid heat from being accumulated on the heat generation side of the Peltier unit 130.

  Furthermore, in the present embodiment, a through hole 113 penetrating from the T-shaped front to the back is formed at the center in the width direction of at least a part of the wide portion range in the support portion 112 in the T-shaped front view.

In other words, the through hole 113 is formed at the center in the width direction so as to straddle the portion 112d that is not inclined from the inclined portion 112c in the vertical direction in the support portion 112.
Thereby, the thickness of the wide portion is reduced by the amount corresponding to the through hole 113, and excessive heat storage is eliminated.
As a result, heat conduction from the contact portion 111 to the lower end of the support portion 112 through the wide portion of the support portion 112 can be improved.
In this embodiment, as shown in FIGS. 1 and 2, a gap S is provided between the lower end 162 a of the side plate 162 and the lower end 163 a of the foot portion 163.

  As a result, hot air (see FIG. 5A) released to the inside of the side plate 162 by the heat radiating intake fan 150 escapes from between the lower end 162a of the side plate 162 and the lower end 163a of the foot portion 163 to the outside of the side plate 162. .

That is, the heat released from the heat-dissipating intake fan 150 located behind the top plate 161 of the erection table 160 to the inside of the lower side plate 162 does not accumulate inside the erection table 160, and the lower end 162 a of the side plate 162 and the foot It escapes from the clearance S between the lower end 163a of the part 163 to the outside of the erection table 160.
As a result, it is possible to efficiently cool the dead body while avoiding heat accumulation inside the side plate 162.

  Moreover, since the air outside the erection table 160 is taken into the heat sink 140 inside the erection table 160 from the gap S, the heat dissipation effect of the heat sink 140 can be further enhanced, and the dead body can be cooled more effectively.

  6A and 6B, the Peltier unit 130 includes a Peltier element 131, a heat absorption side metal 132, a heat generation side metal 133, a lead wire 134, a resin case 135, and silicone. And a sealing material 136.

  Among these, the Peltier element 131 is connected to the lead wire 134, and a ceramic surface (not shown) is formed on both the heat absorption side and the heat generation side of the Peltier element 131.

When a current flows through the Peltier element 131, an endothermic phenomenon occurs on the heat absorption side of the Peltier element 131, and an exothermic phenomenon occurs on the heat generation side of the Peltier element 131.
The heat absorption side metal 132 is disposed in surface contact with the heat absorption side of the Peltier element 131 without any gap.
The heat generation side metal 133 is disposed in surface contact with the heat generation side of the Peltier element 131 without any gap.
The resin case 135 covers the Peltier element 131 and a part of the heat absorption side metal 132 and is bonded to the heat generation side metal 133.

  The silicone sealing material 136 is filled in the resin case 135 in order to eliminate a gap in the resin case 135, and a part of the silicone sealing material 136 is protruded from the resin case 135.

Thereby, even if it is a case where the Peltier unit 130 and the heat-transfer member 110 are screwed and the Peltier unit 130 and the heat sink 140 are screwed, a gap does not occur in the resin case 135.
Further, even when the impact is received, the silicone sealant 136 is elastically deformed to absorb the impact, so that the Peltier unit can withstand the impact.

Even if dew condensation occurs on the heat absorption side, moisture does not enter the resin case 135, so that the Peltier element 131 can be prevented from being damaged.
In this embodiment, the heat transfer member 110 is configured to be screwed to the heat absorption side metal 132 of the Peltier unit 130.
As a result, a gap is less likely to occur between the heat transfer member 110 and the heat absorption side metal 132.

Further, the heat generation side metal 133 of the Peltier unit 130 and the resin case 135 are integrated and screwed to the heat sink base portion 141 of the heat sink 140.
As a result, a gap is less likely to occur between the heat sink base portion 141 and the heat generation side metal 133.
Further, since it is difficult to apply stress to the Peltier element 131, it is possible to prevent the Peltier element 131 from being damaged by the stress.

  That is, since the Peltier element 131 is less likely to receive stress due to thermal expansion and contraction of the heat transfer member 110, the heat absorption side metal 132, the heat generation side metal 133, and the heat sink 140, damage to the Peltier element 131 can be avoided.

  In particular, compared to the conventional structure in which the heat transfer member and the heat sink are screwed together and the Peltier unit is sandwiched, in this embodiment, the burden on the Peltier element 131 is greatly reduced. Can be significantly lengthened.

  The ozone generator 170 generates ozone and ions. Ozone generator 170 generates ozone and ions, so that odors generated from corpses such as small animals can be suppressed. Furthermore, a bactericidal effect can be obtained.

The lid portion 180 is configured to be openable and closable with the upper end 162a of one side plate 162 as a fulcrum. When the lid portion 180 is in the open state, the corpse is taken in and out of the endothermic corpse cooling device. Further, the ozone generator 170 generates ozone and ions in a state where the lid portion 180 is in a closed state and the lid portion 180 covers the upper part of the erection table 160, so that an odor in the endothermic corpse cooling device is generated. Furthermore, it is possible to suppress the odor from leaking to the outside.
The lid 180 is made of a transparent material such as acrylic resin. And the cover part 180 is comprised so that visual recognition is possible even if it is a closed state.
