Abstract

The utility model relates to a novel fixing stand in a radiation mould unit. The stand contains a radiator, a fixing stand and a cooling fan. The fixing stand includes a main body having two sides independently provided with the cooling fan and the radiator, forming a cooling mould unit. The main body is provided with a ventilation hole corresponding to the cooling fan. The utility model is characterized in that the interior wall of the ventilation hole extends inward to have at least one or more fixed fan. The fixed fan of the utility model plays the role of conducting air flows, decreasing the noise caused by the press resonance and removing unnecessary bow wave loss. Also another wind pressure can be formed in the direction of the tangent of the fixed fan, which can avoid wind pressure loss resulted from the mutual interference of the air flows and can be used to increase the cooling efficacy of the fixed fan so as to gain more quick and effective cooling effect and to solve the matter that hot is accumulated in the lower half part of the radiator.

Embodiment

The utility model is about a kind of improved heat radiation module holder, it includes a radiator 10, a holder 20 and a radiator fan 30, radiator 10 direct contact heating bodies are to absorb its heat energy, 30 of radiator fans be utilize holder 20 fixed configurations in radiator 10 tops dispersing heat energy, below promptly enumerate two kinds of preferable enforcement kenels and describe:

As Fig. 2, shown in Figure 3, implement the improved heat radiation module holder that kenel provided for first kind for the utility model, radiator 10 comprises a central heat carrier 11, and central heat carrier 11 peripheries are outward extended with a plurality of radiating fins 12.

Holder 20 has a main body 21, and its end face is provided with fan holddown groove 22, and is fixing for radiator fan 30 assemblings, main body 21 is provided with the ventilation hole 23 of corresponding radiator fan 30 in addition, all projections have a plurality of location divisions 24 in the ventilation hole 23, can establish fixingly with radiator 10 spiral shells, form a heat radiation module.Main body 21 peripheries have the socle 25 of a plurality of downward projections again, and each socle 25 can be installed in the heat radiation module precalculated position of heater top.

In addition, ventilation hole 23 inner peripherals of holder 20 are towards the interior stator blade 26 that is extended with at least more than one, and each stator blade 26 can be the plates with angle of inclination, also can be the kenel that is similar to the fan blade of radiator fan 30.

Fig. 2～shown in Figure 4 for another example, when radiator fan 30 each stator blade 26 of priming airflow passes, stator blade 26 has the effect of steering current, can reduce the noise that pressure resonance is produced, and the tangential direction of stator blade 26 can form another strand blast, can avoid air-flow to disturb the loss of the blast that causes mutually on the one hand, on the other hand the heat dissipation of blast lifting radiator fan 30 thus, the heat energy that radiator 10 is absorbed can be dispersed more rapidly, reaches quicker, more efficient radiating effect.
