When utilizing power-hungry programs or engaging in demanding tasks like gaming, mobile phones produce a lot of heat.

 

This heat has the potential to harm the phone as well as reduce battery life and slow down operations. Nevertheless, innovative phone covers are starting to appear to solve this issue.

Several cutting-edge phone cases with better heat management are discussed on this page.

1.High Thermal Conductivity Materials

1.1. Protective Case and Vehicle Dock System for Enhanced Thermal Management of Mobile Devices

Jerrold Scott Pine, 2023

A method to adapt consumer-grade mobile devices for mission-critical public safety use by using a protective case optimized for temperature regulation and a vehicle dock that can regulate device temperature. The protective case facilitates thermal dispersion from the device to prevent overheating. The vehicle dock maintains optimal device temperature using heating and cooling elements. Pogo pin electrical contacts between the case and dock allow frequent device insertion/removal.

1.2. Protective Mobile Phone Case with Temperature Regulation for Extreme Conditions

Jerrold Scott Pine, 2020

A system for using consumer-grade mobile devices in mission-critical applications like public safety that require ruggedness and extended temperature range. The system involves a protective case optimized for temperature regulation and coupling the device to a vehicle dock capable of maintaining operating temperatures in extreme conditions. The dock uses peltier devices to heat or cool the device as needed, which are monitored by polling internal temperature sensors.

2.Impact-Resistant Frames with Heat Ventilation

2.1. Smartphone Case Design with Ventilation and Environmental Sealing Features

TARGUS INTERNATIONAL LLC, 2022

Protective case for electronic devices like smartphones that allows heat to escape while still protecting the device. The case has a back vent with sealing features to prevent water and dust ingress while still allowing heat to escape from the device. The vent has a series of slits covered by a flexible membrane that can flex to open the slits when pressure builds up inside the case, allowing heat to escape.

US11470934B2-patent-drawing

2.2. Protective Case for Enhanced Heat Dissipation and Impact Resistance

Lina Zhang, 2018

A protective case for portable computing devices that provides impact protection and heat dissipation. The case has a unique frame structure with large openings around the central device area and smaller openings around the edges. This allows impact forces to be defused through the openings rather than directly onto the device. It also has a cushion layer that mirrors and interlocks with the frame structure. This absorbs shocks and vibrations. The case further has slits in the base layer to allow heat generated by the device to dissipate.

3.Removable Temperature Control Inserts

3.1. Smartphone Case with Temperature Control and Enhanced Functionality Features

BLUEBRICK COMPANY, LLC, 2022

An electronic device holder that controls temperature to protect electronic devices like smartphones from harsh conditions while providing features like card reader access. The holder has a shell with a detachable cap and an insert that can be cooled or heated. When closed, the holder partially encloses the device in a cavity and provides a chamber for the insert. A locking mechanism secures it shut. Additional features like camera access, a payment processing attachment, and a card reader slot are included.

3.2. Smartphone Case Design for Enhanced Heat Management Using Disposable Pocket Warmers

Tsutomu TANAKA, 2021

This is a smartphone case that stores and uses disposable pocket warmers to keep the phone warm in cold environments. The case has a dedicated storage compartment for the pocket warmer on the back. This allows the pocket warmer to be rubbed and activated while stored against the phone, maximizing heat transfer. The storage compartment material presses the pocket warmer against the phone for better contact.

3.3. Thermal Management Pouch for Electronic Devices with Temperature-Control Gel

Wan Tjoeng Tsang, Frank Tjoeng Tsang, 2018

A cooling pouch to prevent electronic devices like smartphones and laptops from overheating. The pouch has an inner pocket lined with temperature-controlling gel or material. When a device is placed in the pocket, the gel absorbs the device's heat and keeps it cool. The pouch is made of multiple layers including a plastic outer layer and a shock-absorbing layer to protect the device. It can be closed to securely hold the device inside.

4.Solid-State Heat Pump Integration

4.1. Mobile Device Case with Integrated Solid-State Heat Pump and Fan for Temperature Regulation

ADESA, Inc., 2022

This is a mobile device case that regulates the device's temperature, preventing overheating or freezing. The case has a solid-state heat pump like a Peltier device and a fan. The heat pump cools the device by conductively cooling its surface, and the fan convectively cools the heat pump. The case also has a removable battery cover and battery pocket.

4.2. Temperature-Regulating Mobile Device Case with Integrated Heat Pump and Fan

ADESA, Inc., 2021

A mobile device case can regulate the temperature of the mobile device, such as to cool the mobile device (in the instance of extreme heat) and/or to heat the mobile device (in the instance of extreme cold). The case includes a solid-state heat pump like a peltier cooler to cool the surface of the mobile device conductively and a fan to cool the heat pump convectively.

US20210055771A1-patent-drawing

4.3. Solid-State Heat Pump Mobile Case for Temperature Regulation

ADESA, Inc., 2020

A mobile device case that uses a solid-state heat pump like a Peltier device to cool or heat a mobile device. The case has a housing that encloses the mobile device and contains a Peltier device with a cooling side that contacts the device surface and a heat sink side. A fan cools the heat sink side. This allows the case to conductively cool the device in hot or cold temperatures to prevent performance issues. The case may also have a removable battery cover.

5.Vented Cases for Passive Heat Dissipation

5.1. Protective Mobile Phone Case with Sealed Vent for Enhanced Heat Dissipation

TARGUS INTERNATIONAL LLC, 2023

Protective case for portable electronic devices that provides passive heat dissipation, peripheral access, and protection. The case has a sealed back vent that dissipates heat from the device. The vent has a filter to prevent dust and liquid ingress. The case fully surrounds the device for protection, but the back vent allows heat to escape and provides access to device peripherals like cameras and buttons.

5.2. Protective Mobile Device Cases with Enhanced Cooling and Peripheral Protection

TARGUS INTERNATIONAL LLC, 2020

Protective cases for mobile devices allow cooling and maintain peripheral access while protecting from damage. The case has a vented back panel with an array of small vent holes that allow heat to escape while protecting the device from drops and impacts. The vented back panel also has raised edges around the camera and other peripheral openings to shield them. The vent holes are small enough to prevent the entry of liquids, dirt, or dust. This enables passive cooling and peripheral functionality while protecting the device.
