Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a mechanism of a heating element plastic casing in a narrow space comprises a plastic casing 1, a heat sink a2, a heat sink B3, a heat sink C4 and a heat sink D5, wherein each of the heat sink a2, the heat sink B3, the heat sink C4 and the heat sink D5 is composed of a heat sink plate and a heat sink bump, so that a heat dissipation effect is increased, the plastic casing 1, the heat sink a2, the heat sink B3, the heat sink C4 and the heat sink D5 are made of aluminum alloy, when air flows through the plastic casing, because the heat conductivity of the aluminum heat sink is higher than that of the plastic product, the heat dissipation effect can be significantly improved, so that the heat dissipation function of the plastic casing in the narrow space can be improved at low cost, the heat sink a2, the heat sink B3, the heat sink C4 and the heat sink D5 are embedded in the plastic casing 1 in an insert manner and injection manner, the clamping blocks 11 are abutted against four corners of the heating source 6, so that the stability of the heating source 6 is better, and the plastic shell 1 and the heating source 6 are assembled inside the peripheral component 7.

The working principle is as follows: the radiating fins are embedded in the existing plastic shell 1 in an insert mode and an injection molding mode, and the aluminum radiating fins have higher heat conductivity than plastic products, so that the radiating effect can be obviously improved, and the radiating function of the plastic shell 1 in a narrow space can be improved at low cost.

Through fig. 7 and 8, the heat source 6 is directly assembled on the plastic housing 1, the assembly space of the plastic housing 1 in fig. 8 is very small, and the heat source 6 in fig. 7 is radiated by the plastic housing 1 in fig. 7, so the heat radiation function of the plastic housing 1 is very important, and the heat generated by the heat source (functional electronic component) in fig. 7 is difficult to be completely dissipated because the heat conductivity coefficient of the common plastic is relatively low, but the present invention embeds the heat sink in the form of an insert on the existing plastic housing 1 in an injection molding manner, and because the heat conductivity coefficient of the heat sink made of aluminum is higher than that of the plastic product, the heat radiation effect can be obviously improved, and the heat radiation function of the plastic housing in a narrow space can be improved at low cost.

In summary, the following steps: the utility model discloses a mechanism of heat-generating body plastic casing in narrow and small space buries the fin with the form of inserts and the mode that adopts to mould plastics on current plastic casing 1, because the coefficient of heat conductivity of the fin of aluminium system is higher than plastic products, can obviously improve the radiating effect, can improve the heat dissipation function of plastic casing in narrow and small space with low costs, solved among the prior art because the coefficient of heat conductivity of ordinary plastics is lower, the heat that the source of generating heat 6 sent is hardly by the problem of scattering completely.
