Abstract

DC60 Content disclosed here is a coating housing for use with various electronic components consisting of a substrate coated with a heat-emitting coating containing Thermal radiation properties on the front and back sides, where the Delta difference T1 (= T1B - T1A) between the T1A temperature at the T1 position of the enamel casing as an example and the T1B temperature at the T1 position of A substrate without a coating on it, which is used as Another sample was 2.6 degrees Celsius or more where the temperature was measured using a set. Evaluate the thermal radiation properties as shown in Figure 1 and where there will be Conforms to its basic properties (for example, to maintain airtight conditions to cover Protect the device from water and dust ingress and reduce its size and weight) while keeping Electronic devices have a lower internal temperature. (Heat Radiation Properties) Content disclosed here is a coating housing for use with various electronic components consisting of a substrate coated with a thermal radiation coating containing Thermal radiation properties on the front and back surfaces, where the difference (formula) T1 (= T1B - T1A) between the T1A temperature at the T1 position of the enamel frame, which is used as a sample set, and the T1B temperature at the location. T1 of a substrate without a coating on it, which is used as Another sample was 2.6 ° C or more where the temperature was measured using a kit. Evaluate the thermal radiation properties as shown in Figure 1 and where there will be Conforms to its basic properties (for example, to maintain airtight conditions to cover Protect the device from water and dust ingress and reduce its size and weight) while keeping Electronic devices have a lower internal temperature. (Has properties for radiating heat)
