Abstract
A home appliance may include: a housing; and a heat exchanger disposed inside the housing, the heat exchanger including: a first pipe providing a flow path along which a refrigerant is flowable, and including aluminum, a second pipe adjacent to the first pipe, the second pipe including aluminum, and configured to receive a sensor, and a filler metal configured to couple the first pipe and the second pipe together, At least of a portion of the first pipe or a portion of the second pipe includes a zinc diffusion layer. An electrical potential difference between any two of the filler metal, the first pipe, and the second pipe is 50 mV or less.
Claims20
A home appliance, comprising:
- a housing;
- and
- a heat exchanger disposed inside the housing, the heat exchanger including:
- a first pipe providing a flow path along which a refrigerant is flowable, and including aluminum,
- a second pipe adjacent to the first pipe, the second pipe including aluminum, and configured to receive a sensor, and
- a filler metal configured to couple the first pipe and the second pipe together,
- wherein at least of a portion of the first pipe or a portion of the second pipe includes a zinc diffusion layer, and
- wherein an electrical potential difference between any two of the filler metal, the first pipe, and the second pipe is 50 mV or less.
A heat exchanger comprising:
- a first pipe providing a flow path along which a refrigerant is flowable, and including aluminum;
- a second pipe adjacent to the first pipe, the second pipe including aluminum, and configured to receive a sensor;
- and
- a filler metal configured to couple the first pipe and the second pipe together,
- wherein at least of a portion of the first pipe or a portion of the second pipe includes a zinc diffusion layer wherein the filler metal is an alloy including zinc and aluminum, with zinc present at 10 to 90 wt % relative to a total weight of the alloy.
A home appliance, comprising:
- a housing;
- and
- a heat exchanger disposed inside the housing, the heat exchanger including:
- a first pipe providing a flow path along which a refrigerant is flowable, and including aluminum, and
- a second pipe adjacent to the first pipe, the second pipe including aluminum, and configured to receive a sensor,
- wherein the first pipe and the second pipe are directly bonded so as to be integrally formed, and
- wherein a bonding width of a bonding portion of the first pipe and the second pipe is smaller than a thickness of the first pipe or a thickness of the second pipe.
