The blocker is equipped with air vents and radiators to ensure its stability and reliability


Is it normal for the signal shield I bought to generate heat?

Mobile phone signal blocker is a high-power and high current device. It definitely generates a lot of warmth when working. If the heat cannot be dissipated in a timely manner, it will inevitably affect the operation of the equipment, such as inability to shield signals or unstable interference signals. Overheating of the equipment may cause a fire. Considering signals, jammers are typically used in important locations such as evaluation rooms, meeting rooms, prisons, private meetings, etc. Any type of problem with signal jammers can cause a lot of trouble. That's why we create excellent cooling systems for our products to ensure their stability and reliability.

This blog post will introduce the most common heat dissipation solutions used in signal jammers.

So there's no more trouble, let's get started.

  • 1. Vents

  • A high-power signal jammer using all natural heat dissipation is usually a completely safe heat dissipation cover, and the shell itself is a heat sink. All components such as switching power supply products and ultra-high frequency modules are integrated into the casing.

    The shell material is aluminum, which is die-cast through different molds. Commonly used in places with harsh external environments, such as places with high levels of sand and dust, or places that require explosion-proof boxes, such as gas stations, oil depots, hazardous chemical depots, and other fields.

    Smartphone signal shields using this type of heat dissipation shell typically require a wide protective position and sturdy ability to adapt to harsh environments, while ensuring the normal operation of the internal RF module through natural heat dissipation.

  • 2. Driven cooling

  • There are various types of mobile phone signal blocking devices that are equipped with fans to dissipate heat. The radiator used in this type of mobile phone signal blocker is mainly installed on the casing after thinning the lightweight aluminum material. The RF components and power light components are installed inside the frame.

    The heat dissipation is divided into two parts. On the one hand, it is to extract the heat inside the framework to the outside, send the outdoor air into the room, form air convection, and simultaneously transport the heat to the outside. The second component is to install a fan at the corresponding cooling tooth position of the radiator module. Then the fan dissipates the heat to the area where additional heat is generated to ensure the normal operation of the internal ultra-high frequency module.

  • 3. Heat dissipation: It is both light and company friendly, with good thermal conductivity

  • Among these products, silver has the best thermal conductivity, followed by copper and aluminum. However, silver is expensive and rarely used for heat dissipation; Although copper has good thermal conductivity, it does not dissipate heat quickly, which may cause the phone signal shield to be unusable for one day a day. The heat of the machine cannot be dissipated, forming an imperceptible space in a particularly narrow space.

Thermal resources. If you encounter high temperatures in the summer, you can imagine this risk. By comparison, aluminum is the most perfect. It is lightweight and durable, with good thermal conductivity and fast heat dissipation. The ideal CPU air-cooled heat sink is all made of lightweight aluminum alloy. For this reason, the shell of the smart phone signal shield is all made of cast aluminum (lightweight aluminum alloy) material and copper bars, which achieve rapid heat transfer and heat dissipation through aluminum temperature slots, providing sufficient heat dissipation area for the device.

The contact surface of the signal shield adopts a layout of thickened and red copper, which is most likely to generate heat. Copper bars can quickly absorb heat and increase heat absorption through lightweight aluminum alloys. Internally, the concept of air convection is fully utilized. Immediately determine the temperature level through a thermistor and activate the follower. When the temperature decreases, the wind speed slows down, and vice versa.

Blow the heat generated by internal parts to the outside and restore convection with the surrounding low-temperature air, playing a circulating role. Combine internal and external to create an ideal cooling method. Fully natural ventilation, followed by heat dissipation, heat dissipation, and the internal heat of the phone signal shield is invisibly dissipated.
