Abstract

A reagent cooling box of the present disclosure includes a reagent disk configured to hold a plurality of reagent vessels that holds reagents, a container configured to store the reagent disk in an inside of the container, a drive device configured to rotate the reagent disk in a horizontal direction, and a fan provided to the reagent disk in a direction in which air can be blown in the rotation direction of the reagent disk.

First claim

1 . A reagent cooling box comprising:
a reagent disk configured to hold a plurality of reagent vessels that holds reagents; a container configured to store the reagent disk in an inside of the container; a drive device configured to rotate the reagent disk in a horizontal direction; and a fan provided to the reagent disk in a direction in which air can be blown in a rotation direction of the reagent disk.

2 . The reagent cooling box according to claim 1 , wherein in the fan, an aspiration direction and a discharge direction are on a straight line, and an area on an aspiration side is equal to an area on a discharge side.

3 . The reagent cooling box according to claim 1 , wherein the fan is any one of an axial fan, a mixed fan, or a sirocco fan.

4 . The reagent cooling box according to claim 1 , wherein a plurality of the fans are provided to the reagent disk at equal intervals so as to have the same air blowing direction.

5 . The reagent cooling box according to claim 1 , wherein
the fan is installed below the reagent disk, and the reagent cooling box further comprises a spacer provided between an upper surface of the reagent disk above the fan and the container.

6 . The reagent cooling box according to claim 1 , wherein the reagent disk supports the reagent vessel and the fan such that a bottom of the reagent vessel and the fan are positioned below the reagent disk.

7 . The reagent cooling box according to claim 1 , wherein the container includes:
a thermally conductive heat absorbing container that has an opening in an upper portion and stores the reagent disk; a heat insulating container that stores the heat absorbing container; and a lid provided above the opening.

8 . The reagent cooling box according to claim 7 , wherein the container further includes a heat removing device provided on a side surface or bottom surface of the heat absorbing container.

9 . The reagent cooling box according to claim 1 , further comprising a controller configured to control drive of the fan, wherein
the container includes a lid, and the controller is configured to stop the fan when the lid is opened in a cooled state of the container, and operate the fan after the lid is closed.

10 . An automatic analysis device comprising the reagent cooling box according to claim 1 .
