Proposed is a filter fixing module mounted to a handpiece cooling device having a connecting unit such that a refrigerant supply unit is coupled thereto, the filter fixing module including a body having a support surface formed in a plate shape, and a receiving surface formed on an edge of the support surface and protruding in a first direction relative to the support surface so as to prevent removal of a filter received in the support surface, and a grip unit connected to the body, wherein the grip unit comprises a first grip member and a second grip member extending in directions opposite to the protruding direction of the receiving surface relative to the body.

A thermal insulation backpack enabling a rapid reduction in temperature without removing a product arranged therein and achieving a thermal insulation effect, and an operation method thereof. The thermal insulation backpack comprises a main body (10) and one or more adapter assembly (30). The main body (10) is provided with a thermal insulation accommodation cavity (102) therein, and provided with a connection hole (101) in communication with the thermal insulation accommodation cavity (102). The adapter assembly (30) is inserted into the connection hole (101), and comprises a fixing frame, a sealing screen (32), and a reset assembly. An outer periphery of the sealing screen (32) is provided with a sealing strip (321) protruding outward. A connection recess (316) and a first through slot (312) are provided in the fixing frame. The first through slot (312) is connected to the thermal insulation accommodation cavity (102). The sealing screen (32) is connected to the reset assembly. When the adapter assembly (30) is connected to an external cooling apparatus, the sealing screen (32) moves toward a direction of an interior of the thermal insulation accommodation cavity (102), such that the connection recess (316) is communicated with the first through slot (312). When the adapter assembly (30) is not connected to an external cooling apparatus, the sealing strip (321) presses against a lower end of the connection recess (316), such that the connection recess (316) is not communicated with the first through slot (312).

Containers are provided herein for facilitating freezing, thawing, and/or storage of products that may be perishable, such as pharmaceuticals. The containers can include shells that enclose the product, and that include apertures permitting flow of a fluid through the containers' internal volume. The temperature of the fluid can be selected so as to freeze or thaw the product. The container optionally can include pressure building members that control the flow of the fluid through the containers' inner volume, e.g., increase the fluid flow rate and thus increase the rate with which the fluid is frozen or thawed.

A galley refrigeration system is provided in which a galley cart is positioned in the cavity of a galley compartment comprising at least a cart-facing opening positioned in a vertically intermediate region of the back wall, the galley cart or the galley compartment having a duct-facing opening positioned adjacent to the cart-facing opening. A heat exchanger configured to generate cooling air is provided within the galley compartment, adjacent the vertically intermediate region of the back wall of the galley compartment defining the cavity. An air supply duct, provided at the cart-facing opening, is configured to guide the cooling air from the heat exchanger into the galley cart, and configured to be detachably coupled to the duct-facing opening of the cart or the galley compartment. An electronically actuated valve controls a variable flow rate of the cooling air from the air supply duct into the galley cart.

A refrigeration module, comprising: a module body, in which an installation space is defined; and a refrigeration system disposed in the installation space for use in generating cold, wherein a cold supply port is provided on the module body, the cold supply port is configured to be detachably connected to an external pipeline, and the cold generated by the refrigeration system is supplied to the external pipeline by the cold supply port. Further provided by the present invention is a refrigerator that has the refrigeration module. By means of separating the refrigeration module and a storage portion, the storage portion does not need to give way to the refrigeration system, and the internal volume of the refrigerator may be greatly increased; and the refrigeration module may be freely matched with one or more of the same or different storage portions as needed.
