[0003] The heat dissipation device in the prior art is generally active, that is, the fan and other equipment force the air to flow relative to the heat source to take away the heat. However, this method will increase the power consumption of the product and bring noise and vibration at the same time. In addition, long-term use of the fan During thermal convection, there is still a risk of burns at the air outlet where the heat accumulates
[0004] In the prior art, there is also a method of passive heat dissipation using heat sinks. Although it meets the needs of heat dissipation, there are still defects: heat sinks are generally made of metal and have a high thermal conductivity, so the internal heat will be transferred quickly. To the surface of the product, the temperature difference between the inside and outside of the device will not be too large. In order to protect the user, the temperature on the surface of the device should not be too high, which also limits the limit temperature of the internal components of the device, and a higher limit temperature means The equipment can have higher efficiency, so this method also restricts the improvement of equipment performance

The invention discloses a device shell capable of reducing sensible temperature and a device. The device shell is made of plastics, the heat conductivity coefficient of plastics is 1-20w / mk; and a plurality of protruding parts are formed on an outer surface of the device shell, sunken parts are between the protruding parts, and the protruding parts and the sunken parts are such arranged that when a human body touches the device shell, the human body first contacts with the tops of the protruding parts and does not contact with an entire outer surface of the device shell of a contact position. According to the device shell, while heat dissipation efficiency is improved, sensed temperature of a consumer for the outer surface of the device is effectively reduced, and the risk of occurrence of a scald is reduced; inner elements are allowed to have higher limiting temperature, contributing to improvement of device performance; and the structure is concise, and an extra heat radiation device such as a fan does not need to be added, thereby realizing miniaturization of the device.
Description
technical field [0001] The invention relates to various devices with heating devices inside and their shells. Background technique [0002] In the process of people's life and work, they often come into contact with some products with high heating capacity. The temperature rise caused by heat accumulation will not only affect the working performance and service life of the equipment, but more importantly, it will affect people's use. Discomfort, and even cause burns to the human body, especially for small consumer electronic products, because the internal components are compact and have more opportunities to contact the human body, the above problems are particularly serious, so heat dissipation devices are necessary for these devices indispensable. [0003] The heat dissipation device in the prior art is generally active, that is, the fan and other equipment force the air to flow relative to the heat source to take away the heat. However, this method will increase the powe...
