[0007] By adopting the above technical scheme, the air can flow out from the through grooves to form air flow, the setting of multiple through grooves can improve the flow rate when the wind power is increased, and different numbers of cover plates can be taken according to the demand of the through grooves.

[0008] As a further scheme of the utility model: the upper side of the support is provided with two inward recessed clamping grooves, and the same recessed plate is clamped in the two clamping grooves.

[0009] By adopting the above technical scheme, the two ends of the recessed plate can be clamped into the clamping grooves, so that the support is convenient to take.

[0010] As a further scheme of the utility model: the support comprises a flow guide plate arranged on the side surface of the shell.

[0011] By adopting the above technical scheme, the setting of the flow guide plate plays a guiding role on the wind.

[0012] As a further scheme of the utility model: the upper side of the cover plate is integrally connected with a semicircular plate.

[0013] By adopting the above technical scheme, the setting of the semicircular plate is convenient for taking the cover plate.

[0014] As a further scheme of the utility model: the side surface of the shell is provided with multiple inward recessed heat dissipation grooves.

[0015] By adopting the above technical scheme, the setting of the heat dissipation grooves increases the contact area of the wind and the shell.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] By adopting the above technical scheme, the air can flow out from the through grooves to form air flow, the setting of multiple through grooves can improve the flow rate when the wind power is increased, and different numbers of cover plates can be taken according to the demand of the through grooves.

[0022] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In this embodiment of the utility model,

[0024] A car water pump with a detachable bracket, such as Figs. 1-3 As shown, the device includes a bearing 1, a housing 2, a support 3, a rotating shaft 4, and an impeller 5. The support 3 has multiple through slots 6 evenly spaced through its center. The middle of the wall of each through slot 6 is recessed inward to form a recessed groove 7. A cover plate 8 covers the support 3 through the through slots 6. A recessed block 9, which mates with the recessed groove 7, is integrally connected to the side of the cover plate 8 facing the through slots 6. A water seal 11 is provided on the outer wall of the rotating shaft 4. An air inlet 10 is provided on the upper side of the housing 2. The recessed block 9 and the recessed groove 7 provide a certain degree of damping and wind resistance.

[0025] The upper side of the bracket 3 is provided with two inwardly recessed slots 13, and the two slots 13 engage with the same concave plate 14. The concave plate 14 is divided into two parts and engages with each other. When not needed, the two parts of the two concave plates 14 can be moved away from each other until they are separated, thereby avoiding affecting the installation of the external fan. In addition, when the concave plates 14 are in the engaged state, the engaged part has a damping effect.

[0026] The bracket 3 includes a guide plate 15 disposed on the side of the housing 2.

[0027] A semi-circular plate 16 is integrally connected to the upper side of the cover plate 8.
