Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated vehicles, in particular to a condenser assembly for a bottom-mounted refrigerated van. Background Art

[0002] The refrigeration unit is the heart of a refrigerated truck. It is divided into independent and non-independent units, and there are also different brands of domestic and imported units. The prices also vary greatly, and the refrigeration effect also has its own strengths. The selection of a refrigeration unit is mainly based on factors such as the storage temperature of the transported goods, the size of the truck, the long transportation distance, and the calculation of temperature loss. In the process of converting a van into a refrigerated truck, for cost considerations, the refrigeration unit often uses a non-independent unit. The engine of the van is located at the bottom of the vehicle body. In order to dissipate heat through the wind, most large refrigerated trucks on the market have the condenser assembly installed on the front of the vehicle. However, if the condenser assembly is installed on the front of the van, it is too far away from the engine. Utility Model Content

[0003] The purpose of the utility model is to provide a bottom-mounted condenser assembly for a refrigerated van to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A condenser assembly for a bottom-mounted refrigerated van includes a fixing device, a fan, and a condenser. The fixing device includes a main board and a bottom plate. A plurality of through holes are evenly distributed on the top of the main board. A mounting portion extending leftward is integrally formed on the left side of the main board. A left hanging side plate is bolted and fixed to the mounting portion. A protective portion extending rightward is integrally formed on the right side of the main board. A right hanging side plate is bolted and fixed to the protective portion. Baffles extending downward are integrally formed on the front and rear sides of the main board. The bottom plate is bolted and fixed to the baffles. A condenser is fixedly mounted on the top of the bottom plate.

[0006] A fan cover is fixedly mounted on the multiple through holes of the main board. The fan cover is coaxially arranged with the through hole. A through hole is arranged at the middle position of the top of the fan cover. The fan is bolted and fixed to the fan cover.

[0007] By adopting the above technical solution, the fixing device integrates the fan and condenser into a low-thickness whole, so that it can be fixedly installed on the chassis of the van. The condenser is connected to the evaporator, compressor and other components through a refrigeration hose, wherein the compressor is arranged on the engine of the van chassis and is driven by the engine. The left side of the fixing device is the side facing the front of the vehicle. When the vehicle is driving, the compressor runs with the engine. Part of the air flows in through the gap between the mounting portion and the bottom plate, contacts the condenser for heat exchange, and the other part flows in from the through hole on the left suspension side panel and blows downward on the condenser through the fan, further improving the efficiency of heat exchange. The entire fixing device effectively fixes the condenser assembly to the bottom of the vehicle, so that it can be connected to the compressor on the engine and cool and defrost the interior of the vehicle.

[0008] In a further embodiment, the left suspension side panel and the right suspension side panel have the same shape, a plurality of ventilation holes are provided on the left suspension side panel, a fence is provided on the left periphery of the left suspension side panel, the fence is composed of an upper support plate, a lower support plate, a left support plate and a right support plate, a plurality of waist-shaped grooves are provided on the top of the upper support plate, the waist-shaped grooves are used to bolt and fix the fixing device and the chassis, a plurality of through holes are provided on the lower support plate, the through holes are used to bolt and fix the left suspension side panel to the main board.

[0009] By adopting the above technical solution, since the fan is closer to the vehicle chassis than the condenser, the heat dissipation efficiency of the condenser may be affected if there is not sufficient air flow. The through holes on the left suspension side panel can allow a steady stream of normal temperature air to quickly blow through the condenser through the fan, and the enclosure can connect the main board and the connection part on the chassis of the van, so that the fixing device is firmly fixed to the bottom of the van.

[0010] In a further embodiment, a plurality of through holes are evenly arranged on the bottom of the base plate, and the plurality of through holes are all regular hexagons. The plurality of through holes are used to accelerate air flow to dissipate heat from the condenser.

[0011] By adopting the above technical solution, the multiple through holes on the bottom plate facilitate air flow, while the bottom plate itself can prevent ground debris from splashing during driving, causing bumps and damage to the condenser, and avoid circulating fluid from leaking out and causing damage to the atmosphere.

[0012] In a further embodiment, the fan includes fan blades and a motor, the rotating shaft of the motor is arranged vertically downward, the fan blades are sleeved on the rotating shaft, and the top of the motor is provided with multiple outwardly extending fixing parts, and the multiple fixing parts are all provided with positioning holes.

[0013] By adopting the above technical solution, the fan is set downward, which can quickly blow the wind blowing through the through hole of the left suspension side panel to the condenser. The fan itself has a simple structure and good shock resistance during vehicle driving, which can ensure a long service life and does not require frequent maintenance.

[0014] In a further embodiment, the condenser includes a plurality of metal fins and a plurality of base tubes, the plurality of metal fins are welded and fixed to the base tubes at equal intervals, and the metal fins are used to guide the airflow blowing from the left side of the mainboard to form turbulence.

[0015] By adopting the above technical solution, the presence of fins can greatly enhance the overall heat transfer area of the condenser, making the heat exchange process more efficient. At the same time, the airflow entering from the through-holes of the left suspension side panel forms turbulence under the guidance of the fins, reducing the boundary layer thickness and increasing the convection heat transfer coefficient, thereby effectively improving the overall heat conduction efficiency. Stainless steel fins are also used as the material of the fin tubes, because rainy weather is often encountered during road driving. If steel and aluminum alloy materials are used, they may be quickly corroded.

[0016] In a further embodiment, the fan cover includes a cover net and a base, the cover net is welded to the top of the base, a plurality of positioning mechanisms are welded along the axis on the outer wall of the base, a receiving groove is provided on the top of the positioning mechanism, and the positioning mechanism is used to be plugged and fixed to the chassis.

[0017] By adopting the above technical solution, the installation position of the fixing device can be preliminarily positioned, and after the positioning is completed, it can be fixed and connected by bolting, which effectively increases the installation efficiency.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The fan and condenser are arranged so that the fan can blow downwards over the condenser, further improving the efficiency of heat exchange. The entire fixing device effectively fixes the condenser assembly to the bottom of the vehicle, connecting the condenser with the compressor on the engine, and achieving the effect of cooling and defrosting the interior of the vehicle.

[0020] 2. The left and right suspension side panels allow for a continuous flow of normal-temperature air through the through-holes on the left suspension side panel. The enclosure connects the mainboard to the connection on the van's chassis, enhancing heat dissipation efficiency and firmly securing the fixture to the bottom of the van.

[0021] 3. Through the setting of the positioning mechanism, the installation position of the fixing device can be preliminarily positioned, and after the positioning is completed, it can be fixed and connected by bolting, which effectively increases the installation efficiency.
