Key Findings

The ETENWOLF X5PRO tire inflator completed a full-discharge thermal rise test under a 35–40 psi load in an indoor ambient environment of 26.7 °C; results are provided for reference only against the internal thermal stability standard.

• Test type: Reliability Test (thermal stability)
• Standard: Internal standard
• Samples: 2 units (X5-8#, X5-9#)
• Ambient temperature: 26.7 °C
• Critical hotspot — X5-8#: Cylinder joint reached 95.7 °C (temperature rise 69.0 K)
• Critical hotspot — X5-9#: Cylinder joint reached 87.5 °C (temperature rise 60.8 K)
• Verdict: For reference only (■供参考)

Test Overview

Test Equipment & Setup

Test Procedure

1. Pre-test: Confirm sample quantity (2 pcs, serial nos. X5-8# and X5-9#). Record ambient temperature (26.7 °C). Verify thermocouple placement on all six measurement points: motor, battery, cylinder, cylinder joint, IC, and inductor.
2. Setup: Connect the inflator to a 35–40 psi load. Attach Type-K thermocouple probes to each measurement point per the internal wiring diagram.
3. Operation: Power on the unit and run continuously under the 35–40 psi load until the battery is fully discharged. Log temperature data throughout the run (see sibling sheet 温升变化数据 for time-series data).
4. Post-test: Record peak temperature and calculated temperature rise (K) for each measurement point per sample.
5. Acceptance criteria: Evaluate thermal stability and heat dissipation performance against internal standard. Results for this test are issued for reference only.

Test Data & Results

Observations: Across both samples the cylinder joint recorded the highest peak temperatures (95.7 °C and 87.5 °C) and the largest temperature rises (69.0 K and 60.8 K), making it the primary thermal hotspot. The inductor and IC were the next hottest components. X5-8# ran consistently warmer than X5-9# at all measurement points under identical load and ambient conditions. Full time-series temperature change data is recorded in the companion sheet 温升变化数据.

Frequently Asked Questions

What does the X5PRO thermal rise test measure?

The thermal rise test monitors peak temperatures and temperature rises (in Kelvin) at six internal measurement points — motor, battery, cylinder, cylinder joint, IC, and inductor — while the X5PRO runs continuously under a 35–40 psi load until the battery is fully discharged. The goal is to assess thermal stability, heat dissipation performance, and potential overheating risk.

Which component reached the highest temperature during the X5PRO thermal test?

The cylinder joint was the hottest component in both test samples. Unit X5-8# recorded a peak of 95.7 °C (temperature rise 69.0 K) and unit X5-9# recorded 87.5 °C (temperature rise 60.8 K) at that location, making it the primary thermal hotspot under full-discharge operating conditions.

What does “for reference only” mean in this test report?

“For reference only” (供参考) means the test was conducted to gather baseline thermal data rather than to certify the product against a mandatory pass/fail threshold. No formal pass or fail determination was made; the results are used internally to evaluate design performance and guide further engineering decisions.

What equipment was used to measure temperature in the X5PRO thermal rise test?

A thermal rise tester equipped with Type-K thermocouples was used. Type-K thermocouples are a common industrial-grade sensor suitable for measuring temperatures across the range encountered in inflator components, providing accurate readings at the motor, battery, cylinder, cylinder joint, IC, and inductor locations.
