Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted coolant equipment, specifically a variable-structure vehicle-mounted cooling module assembly. Background Technology

[0002] Cooling equipment, sometimes called a coolant generator, liquid coolant source, or chiller, primarily aims to provide circulating coolant with specific temperature, flow rate, and pressure requirements for a heat load (the object being cooled). Vehicle-mounted cooling equipment is mainly used for heat dissipation in military and civilian lasers, radars, and high-power electronic devices on vehicle platforms. With the rapid development of industry technology, the application of vehicle-mounted cooling equipment has grown rapidly, with an increasing number and variety of models. Consequently, the modular design approach has gradually gained recognition and strengthening from both users and manufacturers. Modular design is a solution to the contradiction between customized and mass production.

[0003] Modular design was first proposed by Herbert Simon, and its concept was initially applied to the modular design of products. Modular design is a design method that, based on functional analysis of products with different functions or the same function but different performance and specifications within a certain range, divides and designs a series of functional modules. Different products can be constructed by selecting and combining these modules to meet different market demands.

[0004] A typical coolant system includes a coolant supply section, a compression refrigeration section, a conventional heat exchange section (when needed), an electrical control section, and system connection piping. The cooling module assembly mainly consists of the compression refrigeration section and the conventional heat exchange section, and is the core of achieving the cooling function. Traditional cooling module assemblies or vehicle-mounted cooling module assemblies are often fixed square structures. Installing them on beveled compartments makes it difficult to achieve a reasonable heat dissipation path, while designing them with beveled structures reveals installation difficulties or inability to meet compartment strength requirements.

[0005] For modular products, which are often embodied as entities composed of modules, decomposition based on mechanical structural elements is an important aspect. Other functional modules also often use mechanical structural modules as carriers to participate in the assembly of the entire machine or system. How to adapt coolant equipment to the characteristics of chamfered container structures, establish a variable modular structure, improve the adaptability of on-board cooling module groups, and create more possibilities for forming modular products or systems is worthy of further research.

[0006] Meanwhile, for the layout of large-capacity cooling liquid equipment in corner-shaped cabins, due to the influence of other factors, there are almost no air inlets and outlets on the bottom and end faces. To exchange a large amount of heat with the outside, heat exchangers will most likely be installed on both sides of the cabin and exhaust fans will be installed on the top slope. In this case, if an effective design solution is not adopted, it will occupy a lot of side space, resulting in the cabin being too long in the driving direction. Utility Model Content

[0007] This invention provides a variable-structure vehicle cooling module assembly to solve the problems existing in the traditional modular architecture of the prior art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The movable radiator (3.4) and the fixed radiator (5.2) are connected to an external coolant source through pipelines to form a coolant circuit.

[0011] Furthermore, the refrigerant inlet and outlet of the movable heat exchanger (3.1) face downwards, and the refrigerant inlet and outlet of the movable heat exchanger (3.1) are connected to the compressor via U-shaped hoses to form a refrigerant circuit.

[0012] Furthermore, the coolant provided by the coolant source is an aqueous solution of ethylene glycol, or an aviation coolant, or a hydrocarbon and organosilicon compound coolant, or a fluorocarbon compound coolant.

[0013] Furthermore, multiple cooling modules are distributed in an array on both sides of the top of the vehicle compartment. Channels are provided between adjacent rows, columns, or rows and columns in the array on the top of the vehicle compartment. These channels are connected to the external environment of the vehicle compartment through air inlets on the vehicle body.

[0014] Furthermore, the horizontal cross-section of the movable heat exchanger (3.1) and the fixed heat exchanger (5.1) is either straight or U-shaped.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment discloses a variable structure vehicle cooling module group, including multiple cooling modules mounted on the top edge of the vehicle compartment. The multiple cooling modules are distributed in an array on both sides of the top edge of the beveled vehicle compartment. Channels are provided between adjacent rows, adjacent columns, or adjacent rows and columns in the top of the beveled vehicle compartment, and the channels are connected to the external environment of the vehicle compartment through air inlets on the vehicle body. Figure 1 , Figure 3 middle, For refrigerant flow direction, For coolant flow direction, This indicates the direction of airflow.

[0027] like Figure 1 As shown, each cooling module includes a frame 2, a compressor, a plate heat exchanger 1, a fan 4.1, a movable heat exchanger 3.1, and a fixed heat exchanger 5.1. One side of the frame 2 faces the interior of the vehicle compartment, while the top and the other side of the frame 2 face the exterior of the vehicle compartment. The top of the frame 2 is a top plate 4.2 with an adjustable tilt angle, and the fan 4.1 is embedded in the top plate 4.2. A movable frame 3.2 is located on the side of the frame 2 facing the interior of the vehicle compartment. The movable heat exchanger 3.1 is fixed in the movable frame 3.2, and the upper end of the movable frame 3.2 is rotatably connected to the bottom left side of the top plate 4.2. When the left side of the top plate 4.2 tilts upwards, the movable frame 3.2 and the movable heat exchanger 3.1 can rise together with the left side of the top plate 4.2. When the left side of the top plate 4.2 returns to horizontal, the movable frame 3.2 and the movable heat exchanger 3.1 can fall together with the left side of the top plate 4.2. The stationary heat exchanger 5.1 is fixed inside the frame on the side facing outwards from the vehicle compartment. For example... Figure 2 As shown, the horizontal cross-sections of the movable heat exchanger 3.1 and the fixed heat exchanger 5.1 are either straight or U-shaped to meet the requirements of heat exchange capacity and space layout.

[0028] The compressor has three refrigerant outlets and two refrigerant inlets. The first refrigerant outlet of the compressor is connected to the refrigerant inlet of the stationary heat exchanger 5.1 via a pipe, and the first refrigerant inlet of the compressor is connected to the refrigerant outlet of the stationary heat exchanger 5.1 via a pipe, thus forming a refrigerant circuit between the compressor and the stationary heat exchanger 5.1. The second refrigerant outlet of the compressor is connected to the refrigerant inlet of the movable heat exchanger 3.1 via a flexible pipe, and the first refrigerant inlet of the compressor is also connected to the refrigerant outlet of the movable heat exchanger 3.1 via a flexible pipe, thus forming a refrigerant circuit between the compressor and the movable heat exchanger 3.1.

[0029] The refrigerant inlet and outlet of the movable heat exchanger 3.1 face downwards, and the refrigerant inlet and outlet of the movable heat exchanger 3.1 are connected to the corresponding refrigerant input and output ports of the compressor through U-shaped hoses 3.3 to form a refrigerant circuit.

[0030] One side of frame 2 is provided with a coolant inlet A and a coolant outlet B, which are connected to an external coolant source via pipelines. Plate heat exchanger 1 has two sets of flow channels: one set for coolant and the other for refrigerant. The two ends of the coolant flow channel of plate heat exchanger 1 are connected to coolant inlet A and coolant outlet B via pipelines, thus forming a coolant circuit by connecting the coolant flow channel of plate heat exchanger 1 to an external coolant source. The second refrigerant inlet and the third refrigerant outlet of the compressor are connected to the two ends of the refrigerant flow channel of plate heat exchanger 1 via pipelines, thus forming a refrigerant circuit between the compressor and the refrigerant flow channel of plate heat exchanger 1.

[0031] The coolant provided by the coolant source is an aqueous solution of ethylene glycol, or No. 60 aviation coolant, or No. 65 aviation coolant, or a hydrocarbon and organosilicon compound coolant, or a fluorocarbon compound coolant.

[0032] like Figure 3 As shown, this embodiment also includes a movable radiator 3.4 and a fixed radiator 5.2. The movable radiator 3.4 is fixed in the movable frame 3.2 and integrated with the movable heat exchanger 3.1, while the fixed radiator 5.2 is integrated with the fixed heat exchanger 5.1. The coolant inlet A is connected to the corresponding end of the coolant flow channel of the plate heat exchanger 1 via a three-way valve 6. One end of the movable radiator 3.4 is connected to the coolant inlet A via the three-way valve 6, and the other end of the movable radiator 3.4 is connected to one end of the fixed heat exchanger 5.1 via a hose. The other end of the fixed heat exchanger 5.1 is connected to the coolant outlet B. Thus, the movable radiator 3.4 and the fixed radiator 5.2 are connected in series and then connected to an external coolant source via the coolant inlet A and coolant outlet B to form a coolant circuit.

[0033] In this embodiment, each cooling module includes two sets of heat exchangers: a fixed heat exchanger 5.1 and a movable heat exchanger 3.1. The fixed heat exchanger 5.1 is vertically installed on the side of the frame 2 facing outwards from the vehicle compartment; the movable heat exchanger 3.1 is vertically installed on a movable frame 3.2 and can move up and down with the movable frame 3.2. After reaching a lower or higher position, it is fixed to the side of the frame 2 facing inwards from the vehicle compartment by a connecting means. The movable heat exchanger 3.1 and the movable frame 3.2 constitute the movable heat exchange assembly 3. Each cooling module also includes a rotatable fan assembly 4, which includes a tiltable top plate 4.2 of the frame and a fan 4.1 embedded in the top plate 4.2. Before unfolding, the fan 4.1 mounted on the top plate 4.2 is horizontally upward, discharging air upwards, and the movable heat exchanger 3.1 is in a low position; after unfolding, the fan 4.1 and the top plate 4.2 are tilted together at an angle α (10°~35°), discharging air obliquely upwards, and the movable heat exchanger 3.1 is in a high position. Each cooling module frame also has a set of external coolant inlets and outlets A and B on one side.

[0034] When the cooling module is an air-cooled condensing compressor unit, the movable heat exchanger 3.1 and the fixed heat exchanger 5.1 serve as condensers. The high-temperature and high-pressure refrigerant discharged from the compressor is divided into two paths and condensed and exchanged in the two sets of heat exchangers. Then, it passes through the throttling element to exchange cooling capacity in the evaporator-side heat exchanger. The coolant enters the cooling system from the coolant inlet A and finally flows out from the coolant outlet B.

[0035] When the cooling module is a combination of air-cooled condensing compressor unit and forced air cooling, it also integrates a movable radiator 3.4 and a fixed radiator 5.2. The principle is the same when the air-cooled condensing compressor unit is working. When switching to forced air cooling, the coolant enters from the coolant inlet A, passes through the three-way valve 6, and dissipates heat in the movable radiator 3.4 and the fixed radiator 5.2, finally flowing out from the coolant outlet B.

[0036] like Figure 4 , Figure 5 As shown in this embodiment, each cooling module is symmetrically distributed back-to-back on the top edge of the vehicle compartment, arranged in rows and columns. Channels are provided between rows, columns, or between rows and columns, and air inlets are provided at the corresponding channel positions on the top of the vehicle compartment.

[0037] After the movable heat exchanger 3.1 is installed upwards to a high position, the space left at the bottom serves as a maintenance surface; the pipes connecting to the movable heat exchanger 3.1 and the movable radiator 3.4 are made of U-shaped stainless steel flexible hoses, and the bending radius and length of the U-shaped stainless steel flexible hoses are determined according to the safe vertical movement distance.

[0038] The number of cooling module combinations and the design capacity of each group are determined based on the specific project optimization. Typically, the number of cooling modules is between 2 and 20 groups, and the cooling capacity of each cooling module is between 10 and 200 kW. The hull used to install each cooling module has reserved installation interfaces and air outlets on the side and top slope, which facilitates the installation of the undeployed cooling module from the outside and meets the air outlet requirements of fan 4.1.

[0039] Each cooling module requires at least one fan (4.1), with the specific number determined based on heat exchange capacity and space layout.

[0040] The movable heat exchanger 3.1, the fixed heat exchanger 5.1, the movable radiator 3.4, and the fixed radiator 5.2 respectively adopt high-efficiency copper tube finned heat exchangers or microchannel heat exchangers.

[0041] This utility model is further described below:

[0042] For example, a cooling module with a cooling capacity of 100kW has external dimensions of 1500×1000×1400 (length×width×height), a chamber width of 3000mm, and a chamber chamfer α of 15°; the movable heat exchanger 3.1 adopts a microchannel heat exchanger with dimensions of 1400×650×25.4 (length×height×thickness), corresponding to a cooling capacity of 33kW, and a theoretical height of 1400-650=750 mm reserved at the bottom; the fixed heat exchanger 5.1 adopts a microchannel heat exchanger with dimensions of 1400×1300×25.4 (length×height×thickness), corresponding to a cooling capacity of 67kW. Assuming a cooling module width of 1000mm, a 15° tilt corresponds to a height of approximately 268mm. With the movable heat exchanger 3.1 installed upwards, its theoretical lower section retains a height of 750 + 268 = 1018mm. This demonstrates that the movable heat exchanger 3.1, designed as a moving component, effectively improves the module's maintainability. Simultaneously, since 33% of the airflow passes through the movable heat exchanger 3.1, mounting it upwards further reduces air resistance.

[0043] When two cooling modules are installed back-to-back and side-to-side, the theoretical width of the channel between the cooling modules is 3000-2×1000=1000 mm, and an air inlet can be easily reserved at the top of the channel.

[0044] Furthermore, if the movable heat exchanger 3.1 were not present, the heat exchange capacity of the fixed heat exchanger 5.1 would increase by 50%, and the corresponding condenser length would increase to 1400 × 1.5 = 2100 mm, meaning the length of one cooling module would increase by 700 mm. If there are three cooling modules on one side, the affected chamber length would be 2100 mm. Therefore, it can be seen that using a cooling module with two sets of heat exchangers saves more space.

[0045] Furthermore, whether the air inlet and outlet of the cooling module use electric dampers, manual dampers, or louvers is not the content to be protected by this patent, and will not be discussed further here.

[0046] The preferred embodiments of this utility model have been described in detail above with reference to the accompanying drawings.

The various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. Such combinations, as long as they do not violate the spirit of this utility model, should also be considered as part of this disclosure. To avoid unnecessary repetition, this utility model will not further describe all possible combinations.

[0047] This utility model is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this utility model and without departing from the design idea of ​​this utility model, all modifications and improvements made by those skilled in the art to the technical solution of this utility model should fall within the protection scope of this utility model.
