Description

Technical Field

[0001] The utility model relates to the field of vehicle heaters, and particularly relates to a high-efficiency parking heater. Background Art

[0002] The parking heater generates heat by burning fuel (such as diesel or gasoline), and transfers the heat to the air or coolant in the vehicle, so as to provide a warm driving environment. Such a heater usually includes components such as a compressor, a combustion chamber, a heat exchanger, and a fan.

[0003] The traditional heater is provided with an air outlet and an air inlet. The cold air enters from the air inlet, passes through the heat exchanger, and then is discharged from the air outlet. Since the cold air only contacts the heat exchanger once and is directly discharged after entering, the cold air may not fully absorb the heat released by the heat source fluid, resulting in a reduction in the heat transfer efficiency and inability to meet the expected heating or cooling requirements. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-efficiency parking heater with high heating efficiency.

[0005] The purpose of the utility model is realized as follows: A high-efficiency parking heater includes a main housing. A heat dissipation air inlet and a main air inlet are provided at the top of the main housing, a heat dissipation air outlet is provided at the bottom, and a main air outlet is provided on the right side. Air blowers are provided at the heat dissipation air outlet, the main air inlet, and the main air outlet. A combustion chamber and a control room are provided inside the main housing. A heat exchanger is provided outside the combustion chamber, and a secondary housing is provided outside the heat exchanger to wrap the heat exchanger. The secondary housing is composed of an annular outer shell, a left side plate, a right side plate, and a raised partition plate. The raised partition plate is set horizontally and abuts against the outer wall of the heat exchanger to divide the heat exchanger into an upper heat exchange area and a lower heat exchange area. A secondary air inlet is provided on the annular outer shell in the upper heat exchange area and close to the right side plate, and a secondary air outlet is provided on the right side plate in the lower heat exchange area. The secondary air inlet is connected to the main air inlet through a pipeline, and the secondary air outlet is connected to the main air outlet through a pipeline.

[0006] Preferably, one end of the raised partition plate extends from the right side plate to the left side, and the other end leaves a gap with the left side plate without abutting, forming a communication channel between the upper heat exchange area and the lower heat exchange area.

[0007] Preferably, the main air inlet sucks in cold air through a blower and then passes through the secondary air inlet, the upper heat exchange area, the communication channel, the lower heat exchange area, the secondary air outlet, and the main air outlet in sequence.

[0008] Preferably, the inner vertical surface of the right side plate of the secondary housing abuts against the right end surface of the main body of the heat exchanger.

[0009] Preferably, the heat dissipation air inlet is located above the control room.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] A secondary housing is provided outside the heat exchanger, and the interior of the secondary housing is optimized and improved. A secondary air inlet, a secondary air outlet and a raised partition are provided, realizing the circulating flow of the cold air after entering. It is ensured that after the cold air enters the secondary housing, it can sequentially pass through the upper heat exchange area and the lower heat exchange area, that is, improving the heat exchange rate between the cold air and the main body of the heat exchanger, avoiding the direct discharge of the cold air without passing through the heat exchanger, and improving the hot air outlet effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] As Figure 1-2 shown, a high-efficiency parking heater includes a main housing 1. There are a heat dissipation air inlet 101 and a main air inlet 102 at the top of the main housing 1, a heat dissipation air outlet 103 at the bottom, and a main air outlet 104 on the right side; there are fans at the heat dissipation air outlet 103, the main air inlet 102, and the main air outlet 104; a combustion chamber 2 and a control room 3 are provided inside the main housing 1. A heat exchanger 4 is provided outside the combustion chamber 2, and a secondary housing 5 is provided outside the heat exchanger 4 to wrap the heat exchanger 4; the secondary housing 5 is composed of an annular outer shell 501, a left side plate 502, a right side plate 503, and a protruding partition 504; the protruding partition 504 is set horizontally and abuts against the outer wall of the heat exchanger 4 to divide the heat exchanger into an upper heat exchange area 401 and a lower heat exchange area 402; a secondary air inlet 505 is provided on the annular outer shell 501 in the upper heat exchange area 401 and close to the right side plate 503, and a secondary air outlet 506 is provided on the right side plate in the lower heat exchange area 402; the secondary air inlet 505 is connected to the main air inlet 102 through a pipe, and the secondary air outlet 506 is connected to the main air outlet 104 through a pipe.

[0019] As Figure 2 shown, one end of the protruding partition 504 extends from the right side plate 503 to the left, and the other end has a gap with the left side plate 502 and does not abut, forming a communication channel 6 between the upper heat exchange area 401 and the lower heat exchange area 402, that is, the secondary housing is divided into a U-shaped flow channel by the protruding partition, increasing the contact time between the cold air and the main body of the heat exchanger and improving the heat output efficiency.

[0020] As Figure 1-2 shown, after the cold air is sucked in through the main air inlet 402 by the fan, it passes through the secondary air inlet 505, the upper heat exchange area 401, the communication channel 6, the lower heat exchange area 402, the secondary air outlet 506, and the main air outlet 104 in sequence; that is, a U-shaped loop is formed inside the secondary housing, and the cold air can contact the main body of the heat exchanger more, avoiding the direct discharge of the cold air from the main air outlet, and greatly improving the efficiency of hot air output.

[0021] As Figure 1As shown, the inner vertical surface of the right side plate 503 of the auxiliary housing 5 abuts against the right end face of the main body of the heat exchanger 4. After the abutment, there is no flow channel between the right side plate and the main body of the heat exchanger, ensuring that the incoming cold air flows from the right end to the left end of the upper heat exchange area.

[0022] As Figure 1 shown, the heat dissipation air inlet 404 is located above the control room. The blower at the bottom heat dissipation air outlet drives the external cold air to enter, directly cooling the control room, which is beneficial to protecting the equipment and extending its service life.

[0023] The working principle of the present utility model is described as follows: During use, the cold air sequentially passes through the main air inlet, the auxiliary air inlet, the upper heat exchange area, the communication channel, the lower heat exchange area, the auxiliary air outlet, and the main air outlet, forming a U-shaped loop within the auxiliary housing. The cold air can contact the main body of the heat exchanger more, preventing the cold air from directly discharging from the main air outlet, greatly improving the efficiency of discharging hot air. At the same time, the blower at the bottom heat dissipation air outlet drives the external cold air to enter, directly cooling the control room, which is beneficial to protecting the equipment and extending its service life.

[0024] The embodiments described above are only used to describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model.
