Claims (21)

A housing portion with a space formed therein;
a thermoelectric element disposed within the housing unit and performing a heat absorbing function; and
It includes a plate coupled to the outside of the bottom of the housing portion,
A wearable device wherein the plate is composed of a curved portion and a flat portion, and at least a portion of the flat portion is in close contact with the bottom of the thermoelectric element. According to claim 1,
A wearable device in which the plate is formed in an oval shape, with a flat portion formed in the center and curved portions formed on both sides in the long axis direction. According to claim 1,
The plate is formed in an oval shape and is bent downward from the flat portion toward both ends in the long axis direction. According to claim 1,
A wearable device in which most of the flat portion of the plate is in close contact with the bottom of the thermoelectric element. According to claim 1,
The plate is a wearable device in which a portion of a curved portion is disposed to be spaced apart from the bottom of the thermoelectric element. According to claim 1,
A wearable device in which a portion of the bottom of the thermoelectric element is in close contact with a flat portion of the plate. According to claim 1,
A wearable device in which a portion of the bottom of the thermoelectric element is spaced apart from a portion of a curved portion of the plate. According to claim 1,
The housing part,
A main housing body forming the lower part; and
It includes a plate seating surface that protrudes downward from the main housing body,
The plate is a wearable device coupled to the plate seating surface. According to claim 8,
A wearable device in which the plate seating surface is formed with a seating surface opening that is open to expose the bottom of the thermoelectric element. According to clause 9,
A wearable device wherein the seating surface opening is formed larger than the bottom of the thermoelectric element to allow the bottom of the thermoelectric element to pass through. According to claim 8,
The plate seating surface corresponds to a flat portion of the plate and is formed as a flat seating surface,
The thermoelectric element is a wearable device whose bottom protrudes downward from the seating plane portion. According to claim 8,
The plate includes a plate fin protruding from the periphery,
A wearable device in which a plate fastening groove is formed on a portion of the circumference of the plate seating surface into which the plate pin is inserted. According to claim 12,
The plate is formed in an oval shape,
The plate fin is a wearable device formed at both ends in the long axis direction and both ends in the short axis direction of the plate. According to claim 12,
A wearable device in which the plate pin is bent in an outward direction of the plate seating surface and coupled thereto. According to claim 8,
A wearable device wherein at least a portion of the circumference of the plate is spaced apart from the circumference of the plate seating surface. According to claim 1,
Further comprising thermal grease provided between the thermoelectric element and the plate to transfer heat,
The thermal grease is a wearable device disposed between the curved portion of the plate and the thermoelectric element. According to claim 1,
It further includes a heat sink that is in close contact with the upper surface of the thermoelectric element and transfers heat between air and the thermoelectric element,
The heat sink is a wearable device disposed on an upper side of a flat portion of the plate with the thermoelectric element interposed therebetween. According to claim 17,
Further comprising a battery that supplies electricity to the thermoelectric element,
The battery is a wearable device disposed on an upper side of a flat portion of the plate with the heat sink and the thermoelectric element interposed therebetween. According to claim 18,
A wearable device in which the thermoelectric element, the heat sink, and the battery are sequentially stacked on an upper side of the flat portion of the plate. According to claim 1,
A wearable device in which at least a portion of the bottom of the housing portion is disposed higher than the bottom of the thermoelectric element. A housing portion with a space formed therein;
a thermoelectric element disposed within the housing unit and performing a heat absorbing function; and
It includes a plate coupled to the outside of the bottom of the housing portion,
A wearable device in which at least a portion of a flat bottom of the thermoelectric element is in close contact with a flat portion of the plate.
