Description

FIELD OF THE INVENTION

The alleged invention relates to the field of mechanical engineering and can be used in mobile facilities for the effective cooling of units that heat up during operation by means of a fluid circulating in the system that is discharged after it is heated in the unit and cooled in a heat exchanger, for example: in mobile radar stations for cooling a phased array antenna in the process of radio emission, in which a large amount of thermal energy is released.

State of the art

A device is known (see patent for the invention of the Russian Federation No. 2171915 dated 07/23/1999), containing a frame with wheels, on which a power unit is mounted, a pump unit, a hydraulic unit connected to its suction line and a hydraulic unit connected to the outlet pipe of the pump unit, a heat exchanger with a cooling system installed on the suction line of the pump unit with the ability to pass the working fluid from the hydraulic tank through the heat exchanger, the cooling system is made in the form of a fan driven into rotation by the power plant , and a hydraulic accumulator connected to the pressure line.

The disadvantage of this device is its narrow functional and operational capabilities, which are expressed in the fact that when used for cooling a large-sized object at the same time by several well-known devices located close to each other, the heat transfer effect of each of them worsens because of a similar device located in close proximity (decreases heat transfer surface, as a result of which neighboring devices will partially heat each other). In addition, due to the dense arrangement of the devices with each other, access to them significantly worsens, which in turn worsens the conditions for their maintenance and repair.

Disclosure of invention

The technical result of the proposed invention is the creation of a highly efficient liquid cooling system, mainly large-sized objects, consisting of identical cooling systems (units) installed next to each other and simultaneously working without loss of cooling in each such mini-system from the influence of neighboring heat, as well as to provide access to elements of each such mini-system for maintenance or repair, i.e. increase of functional and operational capabilities.

The technical effect is achieved by the fact that in the liquid cooling system of a mobile object, it is new that additional similar cooling systems (blocks) are installed in it, installed next to each other and working in parallel and independently from each other, while reducing the effect of heat from on the other hand, the heat exchangers of each of these devices are equipped with a suction duct on the lower side and an exhaust duct on the upper side above the forced fan, the opposite ends of which are fixed to the front when the unit is closed and closed, they are opened by means of a lever system with covers (which together increases the cooling efficiency of the system as a whole), and under the front panel of each of the blocks, a frame with tension extensions on its upper side is alternately placed, and a roller carriage mounted on this frame is moved along to the frame by means of a screw-nut transmission and fastened to the front panel using two intermediate parts to extend each cooling unit from the common case of the cooling system, and on the upper outer surface on the two sides of the frame, in the place of attachment under the front panel, grooves are made for mounting on the frame of the block of brackets with a roller and a fixed protrusion under it to ensure that the block is fully extended to the frame and prevent it from tipping over from the frame after it is fully extended (which allows technical unit maintenance and repair, i.e. operational capabilities of the system increase).

Figures 2 through 10 are shown on an enlarged scale.

The proposed liquid cooling system of a mobile object comprises a rotary container 2 mounted on the vehicle’s wheel frame 1, in which a cooled object 3 is placed, connected by means of a piping system consisting of a suction line 4 with a pump unit 5 and a pressure line 6 with a hydraulic accumulator 7 into a closed loop through a heat exchanger 8, additionally cooled by two electric fans 9, combined in a separate cooling unit, consisting of a frame 10 and a front panel 1 1. Such blocks are located next to each other along the entire wall of the container 2 (see figure 1), while from each cooling block to the cooling object 3 are two pipelines passing under the roof of the container 2 (not shown conditionally), made of flexible tubes at the points of transition from the container 2 to the object 3 and from the container 2 to the hydraulic system in the frames 10 (see figure 2).

The heat exchangers 8 of each of the cooling blocks are equipped on their lower side with a suction duct 12, and with the upper one above the forced suction ventilation of two electric fans 9, an exhaust duct 13, the opposite ends of which are fixed to the frame 10 from the inside of the front panel 11 of the cooling block, from the outside which in these places on the frame are mounted on the axles 14, the same rotary covers 15. At the bottom under the front panel 11 of each of the cooling blocks on the wall of the container 2, alternately attaches I have a frame 16 with tension braces 17 in its upper part on both sides, and in this frame there is a roller carriage 18 with rollers 19, which is moved through the frame by means of a screw 20 - a self-adjusting nut 21. The carriage 18 is fastened to the frame 10 through the panel 11 with two intermediate parts 22 in their upper part, and their lower part, these parts are inserted into the groove on the carriage 18 and can be additionally bolted (see figure 5). On the upper outer surface of the frame 16, on both sides of it, on the side of its attachment to the container 2, under the front panel 11, grooves 23 are made for installation on the frame 10 of brackets 24 with a similar roller 19 by a roller 25 in the upper part of the bracket and a stationary protrusion 26 in the lower part of the same the bracket, the installation of which on the frame 10 is made after partial extension of the cooling unit from the bracket 2 on the frame 16.

On the rotation axes 14 of each of the covers 15, levers 27 and 28 are fixed on one side, pivotally connected to each other by means of a rod 29, and on the other side of the axis 14 of the lower cover 15, an output rod 31 of the electromechanism 32 is connected with a similarly shaped lever 30, providing linear reciprocal - translational movement of its rod, and levers 27, 28, 30 are made of different lengths, i.e. have a different size value from the axis of its rotation to the axis of the swivel with a rod or rod. The housing of the electromechanism 32 is pivotally mounted on the frame 10.

A conical stop 33 is mounted on the outer upper surface of the frame 10 of each of the cooling blocks, interacting with its inclined surface with a similar surface of the spring-loaded stop 34, mounted on the container 2.

The implementation of the invention

The proposed multi-channel liquid cooling system for a mobile object in each of its channels operates as follows: initially, the electromechanism 32 is turned on, when the output rod 31 is extended, the connected lever 30 is pivoted with it, opening the lower cover 15, while the rotation of the lower axis 14 is transmitted to the lever 28 and then through the rod 29 to the lever 27, which rotates the upper axis 14, thereby opening the upper cover 15, while the lower of the covers 15 opens at an angle less than 90 °, to reduce the absorption inward precipitation, and the upper one by an angle greater than 90 ° to prevent reflection of hot air coming out of the upper duct 13 from it downward. The ability to open the covers 15 at different angles is provided by selecting the length of the levers 27, 28, 30. Next, the pump assembly 5 and electric fans 9 are turned on: the coolant passes through heat exchangers 4 and 6 through heat exchanger 8 for its cooling, the efficiency of which is increased due to its additional blowing electric fans 9, which provide a directed air flow in the intake duct 12, which also increases the efficiency of the heat exchanger 8 and minimizes the effect of heat on it from similar cooling exchangers in neighboring blocks. At the same time, the hydraulic accumulator 7 stabilizes the operation of the hydraulic system: it allows to smooth out the pressure pulsations of the coolant and compensates for its expansion arising during its pumping by the pump unit 5. The air heated in the heat exchanger 8 also goes out through the exhaust air duct 13, thereby creating an additional obstacle to the external atmospheric influences, for example, rain, from being sucked into the duct 12. In addition, the proposed air supply system is isolated from its ingress Runner 2: all the air that is sucked in through the duct 12 goes out through the duct 13. Obviously, for maintenance or repair of any of the cooling units, it is necessary to completely remove it from the container 2. To implement this feature while maintaining the health of the product as a whole in the proposed the device under the front panel 11 of the cooling unit to be removed on the vertical wall of the container 2 is attached to the frame 16 with tension braces 17 on both sides, forming a kind of receiving th table for extendable cooling unit. The frame 10 of the cooling block is smaller in size than its front panel 11, so the block cannot be pulled directly onto the frame 16. To ensure the block is pulled out onto the frame 16, a roller carriage 18 is designed, which, through the transmission of screw 20 - nut 21, is moved to the front panel 11 and by two parts 22 are fastened to the frame 10 (see figure 5), while the lower part of the parts 22 is placed in the grooves on the carriage 18.

After unlocking on the front panel 11 of the locking devices, for example, shown under the covers 15 in FIGS. 2 and 6 (this device is shown in the locked position), the cooling unit is prepared for extension. By rotating the screw 20, the carriage 18 is moved on the rollers 19 along the frame 16 and, accordingly, the frame 10 is advanced from the opening along the profile of the container 2, while if the front of the frame 10 moves on the rollers 19 along the frame 16, then the back part own guides in its lower part, for example, on rollers (see figure 2). The process of this extension is suspended for mounting brackets 24 on the frame 10 at the moment of coincidence of the grooves 23 with the place of installation of this bracket on the extendable frame 10 and then continues until the frame is fully extended to a distance that provides access to the vacant opening in the container 2 for inspection and maintenance and it: dust removal, lubrication of the guides, etc., and after installing the brackets 24, the frame 10 moves along the frame 16 in addition to the rollers 19 on the rollers 25. The electric and hydraulic communication with the extended unit is not interrupted due to flexible tubes and electrical cables between the container 2 and the frame 10 of the cooling unit (see figure 2). From unauthorized tipping of the extended unit onto the frame 16, parts 22 and protrusions 26 that come under the frame 16 are protected.

After maintenance or repair, the cooling unit can be tested for operability in the extended state on frame 16.

The mounting of the block mounted on the frame 16 into the container 2 is carried out in the reverse order: by rotating the screw 20, the roller carriage 16 is moved and the frame 10 attached to it moves to the location of the brackets 24 opposite the grooves 23, while the frame 10 will enter its own guides (rollers) on its lower plane into the guides in the opening of the container 2. Remove the brackets 24 and continue the process of pushing the frame 10 into the opening until it stops with its focus 33 in the spring stop 34 (see Fig. 10), thereby fixing the frame 10 in the vertical direction, and Cow devices fix it in the horizontal direction. The spring of the stop 34 provides for the self-installation of its movable conical element without additional adjustment of the stop as a whole in each of the openings of the container 2, in which the cooling blocks are located. Then the frame 16 with the stretch marks 17 is removed: the product is ready for use.

The advantages of the claimed liquid cooling system include: increased efficiency of the heat exchangers by ensuring the passage of directed air flows through them, independent of the heating of neighboring units, which allows you to install similar cooling units close to each other without reducing the efficiency of each of them, t. e. increased functionality of the device.

In addition, the operating capabilities of the system are expanding: a hinge outside an additional receiving table, consisting of a frame 16 with extensions 17 and a carriage 18, allows maintenance personnel to conveniently extend and retract the cooling unit from the container 2 for maintenance or repair, being directly on the surface of the arrangement vehicle i.e. without additional supports, etc. Also, this receiving table is both an operational and an industrial-technological device, since it allows you to install a new cooling unit when it is replaced in the operating organization, as well as its initial installation at the manufacturer, which reduces the number of special equipment used. In addition, the cooling unit is fully extended from the opening of the container 2 with maintenance of the internal cavity of this opening, as well as a check of the health of the unit after its repair in the extended position.
