How does the fever correspond?

This page explains the heat generation measures of the AC adapter in an easy-to-understand manner, including some examples of specific heat generation measures. UNIFIVE is able to offer products that meet customer's needs.

Frequent requests are as follows.

  • We would like to lower the case surface temperature of the AC adapter.
  • We would like to consider using an AC adapter in a special environment.
  • We would like to improve the safety of the AC adapter.
  • We would like to avoid the problem of accidental component failure.
  • We want to reduce heat generation and increase efficiency.

About thermal measures

From customers, we received many inquiries about measures against heat generation to the AC adapter.
In order to ensure product characteristics, safety and quality, measures against heat generation of the AC adapter are indispensable.

So why is it essential?

The reason for this is that the heat generation is greatly affected by product characteristics and safety / quality of the AC adapter. By suppressing heat generation, it can be used for a long time, such as "progress in miniaturization", "improvement in product life span" and "energy saving improvement". This improves the characteristics of the AC adapter and prevents serious accidents such as "influence on the human body due to low temperature burns" and "smoke and ignition" caused by heat generation.

As a measure against heat, we propose the following.

  • Proposal of AC adapter according to your request reference value.
  • Proposal by addition of heat radiation shield etc.
  • Proposal by adding heat generation countermeasure parts.
  • Review of rated capacity
  • Case structure review

Examples of concrete heat generation countermeasures

So, how do you specifically tackle heat generation measures?

First of all, in designing and developing, we meet each technical standard in the evaluation of products, "design and improvement of heat sink", "addition of heat radiation shield", "selection of board excellent in heat radiation", "selection of mounted parts" By conducting various environmental tests such as "Operating Environment Temperature" and "Long Term Reliability Test", ensuring and confirming the quality and safety, it is possible to "Customer Equipment Inspection by environmental conditions "," introduction of safe and safe products into the market "and others.

As an example, you can design and refine the heat sink of the photo, suppress heat generation and ensure "compatibility" by ensuring safety against heat generation. For customers who wish to have the AC adapter according to customer's request, please refer to "review of mounting parts" and "rating review of the AC adapter itself" etc.

In the future UNIFIVE

Towards the IoT era of communication equipment, we will take measures against heat generation so that we can respond to various customers' demands, such as manufacturing according to the usage environment and manufacturing suitable for use conditions of medical equipment.

In addition, we place importance on safety in the market and are conducting safety design that meets the technical standards of the IEC standard of the Electrical Safety Act (PSE) in Japan and abroad (including Japan). Based on customer's requests for various uses in the market, requests according to each user's lifestyle are also possible.

We engage in product proposal, design, development and product production to increase productivity and to meet customer's needs as much as possible.

* By designing the heat sink, it is designed to improve heat dissipation, further miniaturization, safe and safe for customers.
