How do you handle a fever?

We provide a clear explanation of heat generation countermeasures for AC/DC Power Adapters — Desktop & Wall-Mount, including specific examples of such measures. UNIFIVE is able to offer Products that meet our customers' needs.

The following are common requests we receive from our customers.

Lower the surface temperature of the AC adapter case.
Consider using AC adapters in special environments.
Further improve the safety of AC adapters.
Avoid issues caused by accidental component failures.
Improve efficiency by reducing heat generation.

About Heat Countermeasures

We often receive inquiries from customers asking how Unifive addresses heat countermeasures for AC adapters.
Heat countermeasures in AC adapters are crucial responses to ensure product characteristics, safety, and quality.

So why are they considered essential?

The reason is that heat generation greatly affects product characteristics, safety, and quality in AC adapters. By suppressing heat, it is possible to achieve "miniaturization," "product lifespan improvement," and "energy efficiency improvement," leading to longer usage. These measures enhance the characteristics of AC adapters and help prevent serious accidents such as "low-temperature burns and other impacts on the human body" and "smoke or fire" caused by heat generation during market use.

As heat countermeasures, we propose the following:

Proposals of AC adapters tailored to your requested specifications.
Proposals including additional heat-dissipating shields, etc.
Proposals involving the addition of heat management components.
Review of rated capacity.
Review of case structure, and more.

Examples of Specific Heat Countermeasures

Unifive takes heat countermeasures seriously, striving to ensure quality and safety from the design and development stages to provide reliable and safe products.

First, at the design and development stage, various heat countermeasures are considered. We design and improve heat sinks to enhance heat dissipation performance. Additionally, we select heat-dissipating shields and boards with excellent thermal conductivity to achieve effective radiation. We also select internal components, add heat management parts, ensure proper distance between parts, and review case structure. These efforts allow us to address heat-related issues.

At the product evaluation stage, various tests are conducted to confirm that products meet technical standards such as environmental temperature and long-term reliability tests. We also perform tests based on the environmental conditions of customers’ devices to ensure the safety and reliability of the products we provide.

As a specific example, designing or improving the heat sink allows us to achieve product miniaturization. In addition, by suppressing heat generation, we ensure product safety. For customers who wish to use AC adapters in special environments, we work to enable compatibility and realization by reviewing the specifications of both the components and the AC adapter itself.

Looking Ahead at Unifive

In anticipation of the IoT era for communication devices, as well as to meet the usage conditions for medical equipment, we will continue implementing heat countermeasures to meet a variety of customer needs through customized manufacturing suited to their usage environments.

We also prioritize market safety through product designs that comply with Japan's Electrical Appliance and Material Safety Law (PSE) and IEC standards for overseas markets (including Japan). Based on customer needs for various market applications, we accept customized requests suited to each user's lifestyle.

Unifive is committed to proposing suitable products and being involved with sincerity from product design and development through to production, to meet our customers’ needs as much as possible.

* By designing heat sinks to improve heat dissipation and achieve more compact form factors, we strive to ensure safe and reliable usage for our customers.
