FAQs: Custom Mini Refrigerator Components for Consumer Goods Industry Applications
Custom mini refrigerators features for consumer applications are custom aluminum evaporator plate assemblies designed for mini refrigerators with a length of 150-300 mm and a fin height of 5-15 mm making construction of a thermal conductivity of 159 W/m·K and a cooling capacity of 50-150 watts. custom stainless steel door hinge assemblies with a pivot door hinge with tolerances of +- 0.012 mm and a concentricity of .01 mm for 50,000 cycles of an open and close 50,000 operations, custom thermostat housing bodies with an embedded pocket for the sensor being +- 0.012 mm for temp control accuracy of +- 2 degrees centigrade over the region of 2 to 8 degrees centigrade and for the freezer zone of -5 to -15 centigrade with +/- 2 degrees centigrade and evaporator compressors with mounting brackets for the custom plates with vibration isolation of +- .020 mm, custom copper tubing of 6-12 mm with replied diameters of +- 0.020 mm, custom channels designed for door seal retainers with folded edges of +- 0.015 mm form a custom energy efficient mini refrigerators. Custom mini refrigerators are designed to meet +3 degrees centigrade with better energy efficiency (1.8 ratio with energy star rated with 50,000 hours of use).
Aluminum 3003 can absorb and transfer heat well because of its thermal conductivity of 159 W/m·K. This helps in heat absorption and cooling. This type of aluminum can also be formed into any shape. Its lightweight construction makes the fridge weigh less. Aluminum 3003 also has good corrosion resistance. Stainless Steel 304 also has great corrosion resistance, even over 10 years. It has good properties for springs which makes it great for door hinges. Copper is great for thermal conductivity at 385 W/m·K and is very malleable and compliant, which are good properties to have for tubing.
CNC milling creates evaporator plates which hold sets of fins that can be arranged in different patterns to maximize heat transfer with a tolerance of around ±0.030mm in spacing and ±0.040mm in height. 5-axis machining with ±0.020mm accuracy is used to make complex condenser tube geometries. Precision turning creates shafts for the compressors with a tolerance of ±0.015mm in diameter, and high accuracy precision boring is used for the door hinges with pivot holes of ±0.012mm tolerance with a perfectly smooth surface of 0.8μm. For the refrigerant tubes holes of 6-12mm are threaded with ±0.020mm accuracy. To make the mounting holes for the tubes, Thread milling produces mounting holes with ±0.012mm accuracy in depth and pitch. Tube bending creates coils for the condenser with a specific radius. then for the surface of the aluminum a corrosion resistant anodizing is done with type II (10-25μm) and then a powder coating is done on the outer surface. For stainless steel an electropolish is done with a final surface of 0.3-0.5μm and for the zinc handles a chrome plating of 10-20μm is done.
Tolerances that we record include evaporator plate, fins, spacing, height, and fin alignment and thermal performance. which leads to a cooling performance of 50 to 150 Watts and a coefficient of performance of 1.5 to 2.5. We also look at the pivot hole for the door hinge where the tolerance was 0.012 mm over 50,000 door uses, along with proper gasket alignment for energy savings of the unit. We also measure the thermostat sensor pocket tolerance at -0.012 for a thermostat function of ±2 degrees C at an optimal temperature for refrigerator, -5 to -15 degrees C for freeze. Mounting of the compressor with tolerances of ±0.020 mm for vibration to achieve a recommended sound level of 35-45 dBA. We also measure other tolerances with tubing at 0.020 mm for a braze and seal along with the seal of the door and mixer, the condenser bend and radius to achieve a provided surface finish of 0.8 to 3.2 with energy efficiencies of the unit. Each of these meets the DOE and energy star regulations.
Yes, we offer fully automated CMM (Coordinate Measuring Machine) inspection advanced rapid prototyping with an accuracy of +/- 0.005mm, and measurement of evaporator fin spacing using calipers with a +/- 0.030mm tolerance, and measurement of uniformity in fin height, hinge door pivot hole measurement using bore gauges with a 0.002mm resolution +/-0.012mm tolerance, and thermal performance tests, in which we measure the cooling capacity in watts from 50 - 150W at different ambient temperatures, temperature plate uniformity tests +/- 3°C variation in the interior volume of the chamber using a multitude of thermocouples, and door actuator cycle tests for >10,000 performances to hinge verification of fatigue, and verification of gasket compression and door cylinder gasket closure, and pressure decay tests for refrigerant leak detection, and energy consumption tests due to the drawing of power in a range of 60-150 W and > 1.8 EER, controlled noise level measurement tests due to operational sounds in the range of 35-45 dBA, door alignment tests to measure gasket closure, thermostat accuracy checks over the range of +/- 2°C over the range of temperatures, and certificates of compliance to the Energy Star, DOE Energy Conservation standards and UL 250 compliance for household refrigerators.
When it comes to smaller, specialty mini fridges, we will do low-volume production, which means we will work on only 500-10,000 units a year. However, for high-volume production with major appliance brands, we can do anywhere from tens of thousands to hundreds of thousands of units a year. There are certain documentation requirements for high-volume production including an evaporator fin array, a report on the tolerance of the door hinge with validation on cycling it over 50,000 times, thermal performance data with a cooling capacity of 50-150W, a temperature uniformity report with a validation of +/- 3 degrees, energy documentation with an efficiency of over 1.8, compliance with Energy Star, results of a refrigerant leak test, validation of door seal compression, documentation of 35-45 dBA noise level, and material compliance according to RoHS and FDA regulations. We also require a durable product that can withstand over 50,000 operating hours, and we meet ISO 9001 standards that are Energy Star, DOE, and UL certified, which means we are certified for the mini refrigerators used in homes, hotels, and commercial use.
