Embodiment Construction

[0037] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0038] see figure 1 , figure 2 and Figure 6 The heat sink in one embodiment of the present invention includes a base plate 10 and a plurality of tooth plates 20 , and the plurality of tooth plates 20 are arranged at intervals on the base plate 10 to form a heat dissipation fin structure. Specifically, a plurality of tooth pieces 20 are arranged at equal intervals. The substrate 10 is made of thermally conductive material, such as a metal plate or a ceramic substrate 10 . The substrate 10 includes two opposite surfaces, one of which is used to contact the heating element in the communication product, and can be arranged between the substrate 10 and the heating element through a thermally conductive glue or a thermally conductive medium, so that the two are in thermal contact. The other surface of the base plate 10 is used for mounting the plurality of tooth...

Abstract

The invention relates to a radiator, which comprises a base plate and a plurality of tooth pieces, the roots of the tooth pieces are connected to the base plate, a heating area, a downcomer and an interval belt between the two are formed in the tooth piece, and a The first channel and the second channel are located between the heated area and the downcomer. The hydraulic diameter of the pipeline in the heating area is smaller than the critical size, so that the working fluid in the heating area is heated to form a gas-liquid plug flow, and flows into the downcomer through the first channel. The hydraulic diameter of the pipeline of the downcomer is greater than or equal to the critical size, and the pressure of the liquid at the junction of the second channel and the downcomer is higher than the pressure of the liquid at the junction of the second channel and the heated area, so that the liquid in the downcomer passes through the first Two channels flow to the heated area. The radiator of the present invention has the advantage of high heat dissipation efficiency. The invention also provides a communication product.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radiator and a communication product using the radiator. Background technique [0002] Wireless modules are widely used in the field of communication technology, and communication products are set to pass through wirelessly to realize signal transmission and reception. The wireless module generates heat during operation, and the heat dissipation is provided for the wireless module through the setting of the radiator. A conventional heat sink includes a base plate and cooling teeth formed on the base plate. The heat consumption of the wireless module is gradually increasing, and the height of the cooling teeth needs to be continuously increased under the condition that the length and width of the radiator are fixed. However, the heat dissipation efficiency of the heat dissipation teeth gradually decreases with the increase of the height, resulting in a mismatch between t...
