Application Cases of Aluminum Foil Heater Pads for Refrigerator Accessories

 

 

Application Method: Cut the aluminum foil heater pad into strips matching the evaporator coil, attach it to the fin gaps/coil outer wall of the evaporator, and use it with a defrost thermostat and timer.

Function: After 8-12 hours of refrigeration, the aluminum foil heater pad (80-150W) starts automatically, defrosting the evaporator in 5-8 minutes quickly. The thermostat cuts off power automatically after defrosting, preventing frost from blocking the fins and affecting refrigeration efficiency, and solving the problem of “frost accumulation and poor cooling” in frost-free refrigerators.

Advantages: High thermal conductivity of aluminum foil for dead-angle-free defrosting; ultra-thin and flexible design fits the curved surface of the coil without occupying internal refrigerator space.

Applicable Scenario: Water pan + drain pipe assembly of household refrigerators (prone to secondary icing and blockage of defrost water)

Application Method: Wrap a narrow aluminum foil heater pad (10-15mm in width) along the outer wall of the drain pipe, and attach the other end to the bottom of the water pan, with low-power continuous heat preservation (20-50W).

Function: Prevents defrost water from freezing and blocking in the drain pipe, avoids water backflow into the refrigerator that causes food dampness and box corrosion, and is a core protective accessory for the refrigerator drainage system.

 

Applicable Scenario: Fresh frozen island freezers and beverage air curtain cabinets in supermarkets such as Walmart and Yonghui

Application Method: Customize large-size aluminum foil heaters (spliceable) according to the size of the island freezer evaporator, attach them to the back of the evaporator, and match with a high-power defrost timer (4-6 defrost cycles per day), with a power of 150-300W.

Function: Frequent door opening of supermarket freezers leads to fast frost accumulation; the foil heater pad defrosts quickly to ensure stable refrigeration of the freezer, prevent the fresh-keeping effect of fresh food from declining due to frost accumulation, and reduce the time and labor cost of manual defrosting.

Advantages: Aluminum foil is low-temperature resistant and moisture-proof, adapts to the high-humidity and low-temperature working environment of supermarket freezers, and has a long service life.

 

Applicable Scenario: Freezing/refrigeration freezers in commercial kitchens such as Haidilao and Xibei

Application Method: Attach a square aluminum foil heater pad to the bottom of the freezer water pan (30-60W), link it with the freezer power supply, and start automatically at low temperature.

Function: High usage frequency and large ambient temperature fluctuation of kitchen freezers; the heater pad prevents defrost water from freezing in the water pan, avoids ground slip and equipment short circuit caused by icing and overflow, and ensures the operational safety of the commercial kitchen.

 

Applicable Scenario: 5-20㎡ small cold storages in fresh e-commerce front warehouses and community group buying cold storages

Application Method: Customize multiple independent aluminum foil heater pads according to the evaporator zoning of the cold storage, attach them to the evaporators of each zone respectively, and each foil heater pad is equipped with an independent thermostat (200-400W).

Function: Realize zone-controlled defrosting of the cold storage, avoid large temperature fluctuations in the warehouse caused by overall defrosting, ensure the fresh-keeping quality of fresh food (fruits, vegetables, meat, seafood), and reduce defrosting energy consumption.

Advantages: Easy installation of aluminum foil heater pads without modifying the structure of the cold storage evaporator, suitable for the later upgrading and transformation of cold storages.

Applicable Scenario: Low-temperature turnover boxes for fresh cold chain logistics (short-distance distribution)

Application Method: Attach an ultra-thin flexible aluminum foil heater pad to the inner wall of the turnover box, match with a rechargeable lithium battery and a temperature control module, and work at low power (10-30W).

Function: Maintain the temperature inside the turnover box at 0-5℃ (refrigeration) or below -18℃ (freezing) during cold chain distribution, prevent food deterioration caused by high external temperature, and solve the problem of temperature out of control in the “last mile” of cold chain.

Applicable Scenario: Medical refrigerators in hospital pharmacies (for storing vaccines, reagents and medicines)

Application Method: Attach a low-power aluminum foil heater pad (10-20W) to the side wall of the refrigerator inner liner, and match with a high-precision thermostat (temperature control accuracy ±0.5℃).

Function: Medical refrigerators have extremely high requirements for temperature stability; the heater pad starts automatically when the ambient temperature is too low (such as low temperature in the laboratory in winter) for micro thermal compensation, maintaining the internal temperature of the refrigerator in the standard range of 2-8℃, and ensuring the storage safety of vaccines and reagents.

Advantages: The aluminum foil heater pad heats evenly without local overheating, and will not cause temperature shock to medical reagents.
