The cooling effect of the water tank is uneven; the rotation trajectory of the cooling fan is circular, so the optimal cooling range is also a circular range. The four corners of the rectangular water tank are areas with poor cooling effect. Sufficient cooling is not obtained for a long time, the cooling is uneven, and the local temperature is too high. Additional installation and design of a water tank guard is required, which is costly; for traditional water tank structures, an additional and separate guard needs to be designed, and then the guard is fixed on the water tank, which increases the cost.

1. In the utility model, the water tank body of the engine water tank is provided with a cooling fan avoidance recess, which can be fixed on the cooling fan during actual installation, and the cooling fan blows the wind to the cooling fan avoidance depression The fan avoids the side wall of the depression and the cooling through holes at the bottom to blow out, thereby cooling the coolant in the engine water tank, and the cooling effect is better. Another fan guard is installed, which reduces the production cost and reduces the space it takes up;

2. Since the running track of the cooling fan is circular, the area with the best cooling effect is also concentrated around its running track. The flow area is concentrated around the cooling fan as much as possible, which significantly improves the heat dissipation effect. At the same time, compared with the rectangular structure in the prior art, the circular water tank occupies less space, making the installation structure with the engine more compact;

3. Since the running track of the cooling fan is circular, the area with the best cooling effect is also concentrated around its running track. The recessed part of the cooling fan is set as a circular groove, and the cooling fan is installed in it to maximize the cooling effect. optimized cooling effect;

4. The cooling through holes are evenly distributed on the side wall and bottom of the fan avoidance recess, which can increase the contact area between the wind of the cooling fan and the water tank, thereby optimizing the cooling effect;

5. Setting the water inlet below the level of the water outlet can increase the contact area between the cooling liquid and the diffused air as much as possible, thereby optimizing its heat dissipation effect;

6. The water inlet is located at the lowest part of the water tank body, and the water outlet is located at the highest part of the water tank body, which maximizes the contact area between the cooling liquid and the diffuser, and optimizes the heat dissipation effect.

Detailed ways

The present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1-2, an engine water tank includes a water tank body 1. The water tank body 1 is provided with a cooling fan avoiding recess 2, and the side wall and bottom of the cooling fan avoiding recess 2 are provided with cooling through holes 3, so The water tank body 1 is also provided with a water inlet and a water outlet (not shown in the figure).

In the utility model, the water tank body 1 of the engine water tank is provided with a cooling fan avoiding recess 2, which can be fixed on the cooling fan during actual installation. The cooling fan blows the wind to the cooling fan avoiding recess 2, and the wind is The cooling fan avoids the side wall of the concave part 2 and the cooling through holes 3 at the bottom to blow out, thereby cooling the coolant in the engine water tank, and the cooling effect is good. It does not need to install another fan guard, which reduces the production cost and reduces the space occupied.

Further, the water tank body 1 is circular. Since the running track of the cooling fan is circular, the area with the best cooling effect is also concentrated around its running track. When the volume of the main body 1 remains unchanged, the flow area of the cooling liquid is concentrated as much as possible around the cooling fan, which significantly improves the cooling effect. At the same time, compared with the rectangular structure in the prior art, the circular water tank occupies more space. Small, making it more compact with the engine mounting structure.

Further, the cooling fan avoidance recess 2 is a circular groove. Since the running track of the cooling fan is circular, the area with the best cooling effect is also concentrated around its running track, and the cooling fan is avoided from the recess. 2 It is set into a circular groove, and the cooling fan is installed in it, which can optimize the cooling effect to the greatest extent.
