Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of electric heating products, and particularly relates to an isolation heat reflux structure for enhancing air intake volume. Background Art

[0002] In electric heating products, the temperature rise inside the product is relatively high. The size and rotation speed of the fan determine the heat dissipation effect. However, a larger fan has a higher cost and occupies a larger space, and a faster rotation speed generates a greater noise. It is impossible to have both. Currently, in products, increasing the radiator or the fan is used to improve the heat dissipation effect, both of which require an increase in cost and usage space. Summary of the Utility Model

[0003] To solve the problems mentioned in the above background art, the purpose of the present utility model is to provide an isolation heat reflux structure for enhancing air intake volume.

[0007] Preferably, a square air intake groove is provided on one side of the fan installation groove, and the air intake groove protrudes from the bottom of the bracket.

[0008] Preferably, an air outlet is provided on the other side of the fan installation groove, and a wind guide plate is installed on the air outlet.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: rapid heat dissipation is achieved through the mutual cooperation of the bottom case, the fan, and the bracket. Meanwhile, a boss is provided, and the boss is lower than the heating area to prevent hot air from flowing back by heat insulation. The specific advantages are as follows:

[0010] First, the heat dissipation area and the air intake area are increased through the boss. Meanwhile, the boss is lower than the heating area to prevent hot air from flowing back by heat insulation.

[0011] Second, the position of the fan is lower than the boss, increasing the air intake volume. Brief Description of the Drawings

[0019] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and do not limit the scope of the present utility model. The structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present utility model. Therefore, they do not have technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present utility model.

[0020] Here, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, and other details less related to the present utility model are omitted.

[0021] Such as Figures 1 to 3As shown in the figure, the following technical solutions are adopted in this specific embodiment: It includes a bottom shell 1, a fan 2, and a bracket 3; a fan installation groove 3-1 is provided on the bracket 3, and the fan 2 is installed in the fan installation groove 3-1. The bracket 3 is installed on the bottom shell 1. A boss 1-1 is provided at the bottom of the bottom shell 1, and the position of the boss 1-1 corresponds to that of the fan 2; the boss 1-1 protrudes from the bottom of the bottom shell 1; the boss 1-1 is lower than the heat generation area to provide heat insulation and prevent hot air from flowing back; several short heat dissipation grooves 1-2 and long heat dissipation grooves 1-3 are evenly provided on the boss 1-1. The short heat dissipation grooves 1-2 and the long heat dissipation grooves 1-3 can achieve rapid air intake. At the same time, the boss 1-1 increases the air intake volume, enabling rapid heat dissipation in cooperation with the fan 2. A square air intake groove 3-2 is provided on one side of the fan installation groove 3-1, and the air intake groove 3-2 protrudes from the bottom of the bracket 3. The air intake groove 3-2 cooperates with the boss 1-1 to achieve rapid air intake; an air outlet is provided on the other side of the fan installation groove 3-1, and a wind guide plate 3-3 is installed on the air outlet. The wind guide plate 3-3 can achieve rapid air guiding, facilitating rapid heat dissipation. The position of the fan is lower than that of the boss, increasing the air intake volume.

[0022] In this specific embodiment, the boss is lower than the heat generation area to provide heat insulation and prevent hot air from flowing back; the position of the fan is lower than that of the boss, increasing the air intake volume. It is possible to enhance the heat dissipation effect by using a smaller fan in cooperation with the bracket.
