An air compressor head

Technical Field

The invention relates to the field of air compressors, and in particular to an air compressor head.

Background technique

An air compressor, also known as an air compressor, is a device used to compress gas. The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually a motor) into gas pressure energy. It is a compressed air pressure generating device.

A Chinese patent with authorization announcement number CN205207068U discloses an air compressor head, which includes a frame with a motor inside the frame, pump heads for compressing air at both ends of the frame, a cooling fan inside the pump head, the cooling fan sucks air into the pump head and cools the pump head, and three groups of cylinder assemblies for compressing air are provided on the upper part of each pump head. The cylinder assembly is located between the cooling fan and the motor, an air intake muffler is provided on the side of the cylinder assembly close to the cooling fan, and an air outlet is provided on the side of the cylinder assembly away from the cooling fan.

When the above air compressor is working, the motor drives the cylinder assembly to move to achieve air compression. However, when the air compressor is working, the cylinder assembly will generate a lot of heat, which is then dissipated by a cooling fan. However, this method has a poor heat dissipation effect and needs to be improved.

Summary of the invention

The purpose of the present invention is to provide an air compressor head with high heat dissipation effect.

The above technical purpose of the present invention is achieved through the following technical solutions: an air compressor head, including a motor, a pump head located at both ends of the motor and a cylinder assembly arranged on the pump head, a pair of air pipes are connected between the two cylinder assemblies, a plurality of evenly arranged cooling fins are arranged on the top of the cylinder assembly, a gap is provided between each adjacent two cooling fins, a cooling pipe is embedded in the gap, one end of the plurality of cooling pipes are interconnected with a water inlet pipe, and the other end are interconnected with a water outlet pipe.

By adopting the above technical solution, when the air compressor head is working, the motor is started, and the motor pump head and the various components in the cylinder assembly work reciprocatingly to achieve air compression. At the same time, when the air compressor head is working, the cylinder assembly is cooled down by the heat radiation principle of the heat dissipation fins, and then cold water is injected into the water inlet pipe. After the cold water in the water inlet pipe flows into multiple cooling pipes, the cylinder assembly is cooled down by the heat exchange principle of water. Finally, the waste water that has cooled the cylinder assembly is collected in the outlet pipe and then discharged along the outlet pipe. The cylinder assembly is cooled down by the heat radiation principle of the heat dissipation fins and the heat exchange principle of cold water, which improves its cooling efficiency and cooling effect, and achieves the effects of high cooling and high heat dissipation.

The present invention is further configured as follows: the cooling tube is made of copper.

By adopting the above technical solution, since copper has the advantages of strong corrosion resistance, good thermal conductivity and low cost, the cooling pipe made of copper can greatly improve the cooling efficiency and cooling effect of the cooling pipe, thereby further achieving the effect of high cooling and high heat dissipation.

The present invention is further configured as follows: the bottom wall and the top wall of the cooling pipe are both provided with a plurality of baffles which are arranged in a staggered manner.

By adopting the above technical solution, the flow direction of cold water is changed by setting baffles, the flow speed of cold water in the cooling pipe is increased, and the cold water is forced to pass through the cooling pipe horizontally multiple times along a specified distance, thereby enhancing the turbulence of the cold water and improving the cooling efficiency and cooling effect of the cooling pipe.

The present invention is further configured as follows: an outer wall of the motor is covered with a hollow cooling jacket, and the cooling jacket is provided with connecting pipes respectively connected to the water inlet pipe and the water outlet pipe.

By adopting the above technical solution, when cold water is injected into the water inlet pipe, part of the cold water in the water inlet pipe will flow into the cooling jacket along the connecting pipe, and then cool the motor by using the heat exchange principle of water. Finally, the waste water that has cooled the motor will be collected in the water outlet pipe along another connecting pipe, and finally discharged along the water outlet pipe, so that the entire air compressor head can further achieve the effect of high cooling and high heat dissipation.

The present invention is further configured as follows: a cooling fan is provided inside the pump head, and a plurality of exhaust grooves are provided on a side wall of the pump head.

By adopting the above technical solution, when the motor is working, the motor drives the cooling fan to rotate, and at this time, the cooling fan draws cold air from the outside into the pump head, and uses the cold air to cool the pump head, further achieving the effect of high cooling and high heat dissipation. At the same time, the waste gas with heat is discharged along the exhaust groove, thereby preventing the hot air from entering the cylinder assembly and affecting the normal operation of the cylinder assembly.

The present invention is further configured as follows: a flow channel is provided between the outer wall of the cooling tube and the side wall of the heat dissipation fin, an air blowing pipe is provided on the side wall of the pump head, and a plurality of air blowing holes arranged toward the flow channel are provided on the air blowing pipe.

By adopting the above technical solution, when the cooling fan rotates, a part of the cold air sucked in by the fan will flow into the air blowing pipe, and then blow along the air blowing hole to the flow channel formed between the outer wall of the cooling pipe and the side wall of the heat dissipation fin, thereby increasing the air flow rate on the surface of the heat dissipation fin, further improving the heat dissipation effect of the heat dissipation fin, and further achieving the effect of high cooling and high heat dissipation.

The present invention is further configured as follows: a support seat is provided on the outer wall of the lower end of the pump head, a support rod is threadedly connected to the support seat, and a support pad is provided on the lower end surface of the support rod.

By adopting the above technical solution, when the ground where the air compressor head needs to be fixed is uneven, the support pad is pushed to drive the support rod to rotate, thereby realizing the upward or downward movement of the support pad, and until all the support pads are stably in contact with the ground, the support pad is fixed to the ground, so that the entire air compressor head can be kept in a horizontal state during operation, avoiding the air compressor head from tilting, thereby improving the stability and high reliability of the air compressor head during operation.

The present invention is further configured as follows: the outer wall of the support pad is provided with a plurality of embedding grooves.

By adopting the above technical solution, when the support pad is rotated, a rigid tubular or rod-shaped driving member can be inserted into the embedding groove, and the driving member is pushed by the lever principle to drive the support pad to rotate, making the adjustment of the support pad more convenient, quick, time-saving and labor-saving.

The present invention is further configured as follows: the support rod includes a first rod body fixed to the support pad and a second rod body threadedly connected to the support seat; the upper end surface of the first rod body is provided with a sliding hole for the second rod body to be inserted and slid; a shock-absorbing spring is fixed between the lower end surface of the second rod body and the bottom wall of the sliding hole.

By adopting the above technical solution, when the air compressor head is working, the motor will drive the pump head to swing up and down. At this time, the pump head drives the support seat to move, and the pump head drives the second rod body to slide up and down along the inner wall of the sliding hole on the first rod body, while pressing the shock-absorbing spring to compress. At the same time, the rebound force of the shock-absorbing spring itself eliminates the pressure of the second rod body, thereby achieving a good shock-absorbing effect, improving the stability of the entire air compressor head when working, and further achieving the effect of high stability and high reliability.

In summary, the present invention has the following beneficial effects:

1. The cylinder assembly is cooled by the heat radiation principle of the heat dissipation fins and the heat exchange principle of the cooling pipe, which improves the cooling efficiency and cooling effect of the entire air compressor head, achieving high cooling and high heat dissipation effects;

2. The motor is cooled by the cooling jacket, and the pump head is cooled by the cooling fan, so that the whole air compressor head can further achieve the effect of high cooling and high heat dissipation;

3. The air flow rate on the surface of the heat sink fins is increased by setting an air blowing pipe, thereby further improving the heat dissipation efficiency and heat dissipation effect of the heat sink fins;

4. By providing a height-adjustable support pad, the air compressor head can be used on uneven ground. At the same time, by providing a support rod with a shock-absorbing structure, the stability of the entire air compressor during operation is improved, achieving the effect of high stability and high reliability.

Detailed ways

The present invention is further described in detail below in conjunction with the accompanying drawings.

An air compressor head, as shown in FIG1 and FIG2, includes a motor 1, a pump head 2 located at both ends of the motor 1, and a cylinder assembly 3 arranged on the pump head 2, and a pair of air pipes 31 (see FIG4) are arranged between the two cylinder assemblies 3. A support seat 4 is arranged on the outer wall of the lower end of the pump head 2, a support rod 5 is threadedly connected to the support seat 4, a support pad 6 is arranged on the lower end surface of the support rod 5, and a plurality of embedding grooves 61 are arranged on the outer wall of the support pad 6.

When using the above-mentioned air compressor head, place the air compressor head on the ground, then insert a rigid iron rod or iron pipe into the embedding groove 61, push the iron rod or iron pipe to drive the support pad 6 to rotate, and the support pad 6 drives the support rod 5 to rotate, thereby realizing the upward or downward movement of the support pad 6, until all the support pads 6 are stably in contact with the ground, and then the support pads 6 are fixed to the ground.

When the air compressor head is working, the motor 1 is started, and the motor 1 drives the crankshaft (not shown in the figure) in the pump head 2 to rotate, and the crankshaft drives the piston (not shown in the figure) in the cylinder assembly 3 to reciprocate, thereby compressing the air.

As shown in Figure 3, the support rod 5 includes a first rod body 51 fixed to the support pad 6 and a second rod body 52 threadedly connected to the support seat 4. The upper end surface of the first rod body 51 is provided with a sliding hole 53 for the second rod body 52 to be inserted and slid. A shock-absorbing spring 54 is fixed between the lower end surface of the second rod body 52 and the bottom wall of the sliding hole 53.

When the air compressor head is working, the motor 1 (see Figure 1) will drive the pump head 2 (see Figure 1) to shake up and down. At this time, the pump head 2 drives the support seat 4 to move, and the pump head 2 drives the second rod body 52 to slide up and down along the inner wall of the sliding hole 53 on the first rod body 51, and at the same time compresses the shock-absorbing spring 54. At the same time, the rebound force of the shock-absorbing spring 54 itself eliminates the pressure of the second rod body 52, thereby achieving a good shock-absorbing effect, improving the stability of the entire air compressor head when working, and achieving the effect of high stability and high reliability.

As shown in Figures 1 and 4, a plurality of evenly arranged heat dissipation fins 32 are arranged on the top of the cylinder assembly 3, and a gap 33 is arranged between two adjacent heat dissipation fins 32. A cooling tube 7 made of copper is embedded in the gap 33, and a plurality of baffles 71 arranged in an interlaced manner are arranged on the bottom wall and the top wall of the cooling tube 7 (see Figure 5). A water inlet pipe 72 is arranged at one end of the plurality of cooling tubes 7, and a water outlet pipe 73 is arranged at the other end. The outer wall of the motor 1 is covered with a hollow cooling jacket 11, and a connecting pipe 12 is arranged on the cooling jacket 11, which is respectively connected to the water inlet pipe 72 and the water outlet pipe 73.

When the cylinder assembly 3 is working, the heat radiation principle of the heat dissipation fins 32 is used to dissipate heat and cool the cylinder assembly 3. At the same time, cold water is introduced along the water inlet pipe 72. After a part of the cold water in the water inlet pipe 72 flows into the multiple cooling pipes 7, the heat exchange principle of water is used to cool the cylinder assembly 3. At the same time, another part of the cold water in the water inlet pipe 72 flows into the cooling jacket 11 along the connecting pipe 12, and the heat exchange principle of water is used to cool the motor 1. Finally, the waste water that has cooled the cylinder assembly 3 and the motor 1 is collected in the water outlet pipe 73 and discharged along the water outlet pipe 73, thereby achieving the effect of high cooling and heat dissipation by water cooling.

As shown in Figure 1, a cooling fan 21 is provided inside the pump head 2, a plurality of exhaust grooves 22 are provided on the side wall of the pump head 2, a flow channel is provided between the outer wall of the cooling tube 7 and the side wall of the heat dissipation fin 32, and an air blowing pipe 23 is provided on the side wall of the pump head 2. A plurality of air blowing holes 24 arranged toward the direction of the flow channel are provided on the air blowing pipe 23.

When the motor 1 is working, the motor 1 drives the cooling fan 21 to rotate, and the cooling fan 21 sucks the cold air from the outside into the pump head 2, and at the same time, the waste gas with heat is discharged along the exhaust groove 22, thereby preventing the hot air from entering the cylinder assembly 3 and affecting the normal operation of the cylinder assembly 3. At the same time, a part of the cold air sucked by the fan will flow into the blowing pipe 23, and then blow along the blowing hole 24 to the flow channel formed between the outer wall of the cooling pipe 7 and the side wall of the heat dissipation fin 32, thereby increasing the air flow rate on the surface of the heat dissipation fin 32, and further improving the heat dissipation effect of the heat dissipation fin 32.

Working principle: When the above-mentioned air compressor head is used, the motor 1 is started, and the motor 1 drives the crankshaft in the pump head 2 to rotate, and then the crankshaft drives the piston in the cylinder assembly 3 to reciprocate, thereby achieving air compression. When the air compressor head is working, the cylinder assembly 3 and the motor 1 are cooled by heat exchange with cold water, and the pump head 2 is cooled by the cooling fan 21, so that the above-mentioned air compressor head achieves the effect of high cooling and high heat dissipation.
