Earlier on Monday, Chinese tech giant OnePlus held a launch event where it unveiled the OnePlus Ace 2 Genshin Impact limited edition. The tech giatn equally announced a number of accessories, one fo which is the OnePlus 45W Liquid Cooling back clip. The cooling device is reputed as the first liquid cooling radiator designed for mobile phones.

Recall that OnePlus first announced the innovative yet minimalist product at MWC 2023 in February but the pricing and availability details were lacking at the time. The product is now available in China and is priced at 469 yuan ($68). We expect the company to release the product for the global market pretty soon.

As a reminder, the liquid cooling back clip from OnePlus is designed to fit perfectly onto the back of the phone in other to discipate heat generated during highly demanding tasks like hardcore gaming.

Flagship smartphones and even high-end mid-range models are usually fitted with powerful CPUs which allow games and other apps with powerful graphics and which uses a considerable amount of resources. These apps are usually power hungry and enerate a lot of heat. Thus, manufacturers have in recent times deploy internal cooling systems of these flagship and mod-range models to dissipate the heat generated during such intense usage. Sometimes, the internal cooling mechanism may not be adequate in cooling the device and that gave birth to external cooling devices. Xiaomi, Razer and even OnePlus have several models under their brand names but they are all air-cooled.

The new OnePlus 45W Liquid cooling device features two important parts. There is the part that attaches to the smartphone’s back panel and a second part which is a box-shaped cooling pump connected to the first part via a cable. Once the cooling device is snapped onto a smartphone, it starts working automatically. It subsequently stops working if it is detached. The back clip consists of a 40mm x 40mm TEC cooling sheet whie the external cooling pump has a 180,000m㎡ cold radiator with a heat dissipation power of 45W.

OnePlus claims the 45W Liquid Cooling back clip is capable of reducing the device’s temperatures by up to 20°C, which is a significant gap compared to the current air-cooled radiator from OnePlus. While this model may offer better cooling and perhaps longer usage time, the design which sees the back clip attached to a cooling pump via a wire may discourage some.
