Refrigerator appliance

A refrigerator comprising:

• an evaporator (i) having refrigerant tubes configured to route refrigerant through the evaporator and (ii) fins configured to facilitate heat exchange between the refrigerant and air being directed across the evaporator;
• a drain pan configured to receive condensation formed on an exterior of the evaporator;
• a heater tube (i) having first section that is internal relative to first and second ends of the evaporator and (ii) a second section that is external relative to the first and second ends of the evaporator, the second section extending to the drain pan;
• and
• a bracket (i) secured to the evaporator, (ii) engaging the second section of the heater tube, and (iii) biasing the second section of the heater tube into contact with the drain pan, wherein (a) the bracket includes a main body and a biasing arm protruding from the main body (b) the bracket engaging the second section of the heater tube and biasing the second section of the heater tube into contact with the drain pan corresponds to the biasing arm engaging the second section of the heater tube and biasing the second section of the heater tube into contact with the drain pan, and (c) the biasing arm engaging the second section of the heater tube and biasing the second section of the heater tube into contact with the drain pan corresponds to the biasing arm contacting a top of the second section of the heater tube and biasing the second section of the heater tube such that a bottom of the second section of the heater tube contacts the drain pan.

A refrigerator comprising:

• a heat exchanger having an array of tubes configured to route refrigerant through the heat exchanger;
• a pan configured to catch condensation formed on an exterior of the heat exchanger;
• a heater (i) secured to the heat exchanger and (i)) having a protruding portion extending from the heat exchanger to the pan, and
• a bracket (i) secured to the heat exchanger, (ii) engaging the protruding portion, and (iii) biasing the protruding portion into contact with the pan, wherein (a) the bracket includes a main body and a biasing arm protruding from the main body, (b) the bracket engaging the protruding portion and biasing the protruding portion into contact with the pan corresponds to the biasing arm engaging the protruding portion and biasing the protruding portion into contact vi the pan, and (c) the biasing arm engaging the protruding portion and biasing the protruding portion into contact with the pan corresponds to the biasing arm contacting a top of the protruding portion and biasing the protruding portion such that a bottom of the protruding portion contacts the pan.
