Abstract
The utility model relates to a modular heat radiating fan structure. At least two fan components which form juxtaposition are arranged in the containing space of a fan housing seat. The sides of the fan components corresponding to each other are provided with a partition board which can divide the fan components and is shrunk inwards for an appropriate distance along the air access surface of the housing seat. When vanes are rotated toward the direction of the partition board each other, the field domain area of an air access port is increased by the partition board shrunk inwards. The air resistance is effectively reduced, and the high air flow is obtained. The utility model is additionally provided with the other fan component corresponding to the fan components so that the array of the fan components and the other fan component form an array form installation, wherein, the first row of which is fan components and the second row of which is the other fan component. A plurality of flow conducting wings are arranged on stators of the fan components in the first row, and the flow conducting wings and the vanes of the fan components in the first row are installed in an opposite direction. When the vanes of fan components of the first row are rotated toward the direction of the partition board each other. After the flow conducting wings conduct and rectify the flow, the vanes of the other fan component in the second row is correspondingly driven to contrarotating in a reverse direction, and then the maximum airflow of multiplication is obtained.
Description
Technical field
The utility model is about a kind of radiator fan structure, refer in particular to a kind of modular radiator fan structure, be provided with the fan member that is arranged side by side at least more than two in it, by a dividing plate it is separated therebetween, and make this dividing plate along the suitable distance that contracts in the air discrepancy face of fan case seat, field domain area with the air gateway that increases fan member makes it have maximum air mass flow.
Background technology
As everyone knows, significantly progressive along with electronics, network communication product science and technology, fan is used very extensive, and the planning of its function and purposes is more satisfied every electronics, network communication product and sophistication day by day gradually.With existing industrial server, its design height is IU (IU=44.45mm), yet, along with the related electronic components of server inside and the processing speed of processor (CPU) speed, cause it under running or operating state, can send high heat, therefore thereupon, a large amount of hot gas that it produced, promptly need pass through at least one fan, be lower than maximum operating temperature, make server that one normal environment of operation be arranged to make its surface temperature.
Employed fan specification in the common server, be generally the specification of one 40mm * 40mm * 20mm, the fan radiating efficiency of this specification is than the fan of other small dimension, as: 30mm * 30mm * 10mm and 25mm * 25mm * 10mm is good, simultaneously, along with the design of fan shaft volume is more little, its making is difficult more, and price is also expensive more.Therefore, considering that the fan specification with this 40mm * 40mm * 20mm is applied in the confined space of this server inside, is the existing practice under its cost, radiating efficiency and the structure.
Consult shown in Figure 1, because employed fan in the existing server, all be to utilize the side arranged side by side mode of most fan assemblys 3 by its fan case seat 31 adjacent one another are, locking is in the housing 2 of this server, so when this fan assembly 3 when carrying out thermolysis, can make the hot gas that is produced in the server, discharge outside the housing 2 of server, or cool ambient air directly is blown in the housing 2 of server, make the surface temperature in the server be lower than maximum operating temperature, make server maintain normal operation state.Its major defect is:
1, this fan assembly causes the field domain area of its air gateway limited because of the tectonic relationship of its shell block, can't obtain bigger air mass flow, so the maximum quantity of wind that it produced promptly is restricted significantly;
2, this fan assembly locking mode arranged side by side trouble and time-consuming comparatively in locking, and in the limited installing space of server, also seeming takes up space, and do not meet now product towards the demand of compact design.So the fan specification of this 40mm * 40mm * 20mm though can reach radiating effect partly, because of structure and the set-up mode thereof that is subject to this fan case seat, causes its radiating effect still to be very restricted in practical application.
At the shortcoming of said fans, the inventor through the permanent research and experiment of making great efforts, creates a kind of simply constructed modular radiator fan structure of the present utility model to be engaged in this series products manufacturing experience for many years finally.
