Description

Technical Field

[0001] The present application relates to the field of air pumps, and in particular, to an air pump with high efficiency in heat dissipation. Background Art

[0002] Air pump is a device that removes air from a closed space or adds air to a closed space. Air pumps are mainly divided into electric air pumps, manual air pumps, and foot-operated air pumps. Electric air pumps. Air pumps powered by electricity continuously compress air to generate air pressure. They are mainly used for pumping, sewage treatment, electroplating, aeration of biogas tanks, tunnel ventilation, etc.

[0003] At present, air pump heat dissipation is usually achieved by setting cooling fins on the pump body, and transferring heat to the air through the fins for heat dissipation. Since the air is not circulating, a fan is usually used to generate airflow, but the airflow can only flow in one direction. Due to the irregular shape of the air pump, the airflow cannot flow on the surface of the air pump, resulting in poor heat dissipation.

[0004] Therefore, a high-efficiency heat dissipation air pump with good heat dissipation effect is needed. Summary of the invention

[0007] By setting the guide shell, the airflow generated by the fan can flow along the surface of the pump body to ensure the heat dissipation effect.

[0008] Furthermore, there is a gap between the first air guide portion and the rear end of the motor portion for the airflow generated by the heat dissipation blades to flow into.

[0010] Furthermore, a groove recessed in a direction away from the motor part is provided on the first end wall at the connecting edge of the motor part, and a first heat dissipation fin is provided on the first end wall, and the heat dissipation fin extends into the groove.

[0011] The first heat dissipation fins are provided to guide the airflow and remove the heat through the airflow.

[0012] Furthermore, the guide housing is connected with a baffle parallel to the second end wall, and a gap exists between the second end walls.

[0013] Furthermore, the baffle plate and the second end wall form a heat dissipation space, and the heat dissipation space is connected vertically for gas to flow out.

[0014] The air flow is made to flow on the surface of the pump body part and the motor part through the first air passage and the second air passage.

[0015] Furthermore, a plurality of groups of second heat dissipating fins extending vertically are evenly distributed on the second end wall.

[0016] The airflow is guided by the second heat dissipation fins so that the heat on the second end surface is taken away by the exhaust airflow.

[0017] Furthermore, a lifting ring is integrally formed on the upper side of the pump body.

[0018] The installation and transportation are convenient by setting the lifting ring.

[0019] Further, small fins are provided at the heat dissipation fin gaps of the second end wall, and the small fins are distributed circumferentially on the second end wall to form an incomplete ring.

[0020] Some of the heat dissipation fins on the second end wall are provided with reinforcement protrusions, and the reinforcement protrusions are distributed at the incomplete annular notches.

[0021] The beneficial effect of the present application is that it provides an air pump with good heat dissipation effect and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] Reference Figure 1-4 , an air pump with high efficiency heat dissipation, comprising: a pump body, the pump body comprising: a pump body part 100, a motor part 103, and the pump body further comprising: a first end wall 104, a second end wall 105, a first heat dissipation fin 106, and a guide housing 107. The pump body part 100 comprises a pump body part 100 and a motor part 103 connected to each other, an impeller is rotated in the pump body part 100, one end of the main shaft of the motor part 103 is connected to the impeller and the other end is connected to the heat dissipation blades, and the motor part 103 generates an airflow flowing from the motor part 103 to the pump body part 100. The first end wall 104 is an end wall of the pump body part 100 connected to the motor part 103, and the second end wall 105 is an end wall of the pump body part 100 away from the motor part 103. A first heat dissipation fin 106 is arranged on the side wall of the motor part 103, and a second heat dissipation fin 101 is arranged on the pump body part 100, and the first heat dissipation fin 106 extends toward the pump body part 100.

[0037] In one embodiment, the projection range of the motor part 103 on the first end wall 104 is smaller than the first end wall 104, and the airflow flows from the motor part 103 to the pump body part 100, and the heat is taken away by the airflow, and the first heat dissipation fins 106 guide the airflow. The housing blocks the airflow, so that the airflow flows along the surface of the pump body part 100 and the motor part 103, ensuring the heat dissipation effect.

[0038] The flow guide housing 107 includes: a first flow guide portion 109 extending axially along the pump body and a second flow guide portion 110 extending radially along the pump body. A first axially extending air channel 111 is formed between the first flow guide portion 109 and the pump body; and a second radially extending air channel 112 is formed between the second flow guide portion 110 and the pump body.

[0039] In one embodiment, the second guide portion 110 is connected to a guide frame 102 , and a guide space is formed between the guide frame and the pump body. The guide space is connected to the second air channel 112 and extends along the surface of the pump body to one side of the second end wall 105 .

[0040] In one embodiment, the first air guide 109 is installed on the side wall of the motor part 103 and covers part of the first heat dissipation fins 106 on the side wall of the motor part 103. The first end wall 104 is provided with a groove 108 that is recessed away from the motor part 103 at the edge of the motor part 103, and the first end wall 104 is provided with a first end wall 104 that extends into the groove 108. A first air channel 111 is formed between the first air guide 109 and the motor part 103, and the first air guide 111 is directly opposite to the groove 108.

[0041] In one embodiment, the airflow flows into the groove 108 through the first air channel 111, so that the airflow is fully mixed in the groove 108, avoiding airflows of different temperatures at different positions from directly flowing to the surface of the pump body 100, resulting in uneven temperature of the pump body 100.

[0042] A second air channel 112 is formed between the second flow guide portion 110 and the pump body portion 100 , and the first air channel 111 is in communication with the second air channel 112 .

[0043] In one embodiment, the air flow flows into the second air channel 112 through the first air channel 111 , and can flow along the surface of the pump body portion 100 while dissipating heat through the first heat dissipation fins 106 and the second heat dissipation fins 101 .

[0044] The guide housing 107 is connected with a baffle 118 parallel to the second end wall 105, and a gap exists between the baffle 118 and the second end wall 105 to form a heat dissipation space 113. The heat dissipation space 113 is connected with the guide space and penetrates vertically.

[0045] In one embodiment, the airflow flows along the surface of the pump body 100 to the heat dissipation space 113 , and is discharged from the heat dissipation space 113 in the up and down directions.

[0046] A plurality of groups of second heat dissipating fins 101 extending vertically are evenly distributed on the second end wall 105 .

[0047] In one embodiment, the exhaust direction of the airflow in the heat dissipation space 113 is consistent with the extension direction of the second heat dissipation fins 101, so that the second heat dissipation fins 101 can guide the airflow while also taking away the heat through the airflow.

[0048] The upper side of the pump body 100 is integrally formed with a hanging ring 114, and the gap between the second heat dissipation fins 101 is provided with small fins 115, which are circumferentially distributed on the second end wall 105 to form an incomplete ring. Part of the second heat dissipation fins 101 are provided with reinforcement protrusions 116, which are distributed at the gaps of the incomplete ring.
