The hills are used for increasing the heat dissipation area of the hot ends 502, and the hot ends 502 of the heat exchange plates 5 are close to the cold ends of the adjacent heat exchange plates 5, so that the hot ends 502 can exchange heat with the cold ends through air, and the heat exchange efficiency of the heat exchange plates 5 is further improved in an auxiliary mode.
In a second embodiment of the present invention,
the hot end 502 of the heat exchange plate 5 is close to the hot end 502 of the adjacent heat exchange plate 5;
the heat exchanger further comprises a wind row 9 and an arc-shaped guide plate 8, wherein the wind row 9 consists of a frame and a plurality of fans, T-shaped rails are arranged on two sides of the frame and are connected with T-shaped slide ways 501 on two adjacent heat exchange plates 5, two cushion blocks are arranged on the concave end faces of the guide plate 8, two clamping plates 801 are arranged on each cushion block, and the clamping plates 801 are clamped with clamping shafts 602;
the two ends of the clamping plate 801 are positioned between the two adjacent hot ends 502, and the wind row 9 is positioned between the two adjacent cold ends. Through setting up wind row 9, the accessible fan increases the circulation of air between two adjacent cold junction, and the air is sent into between two adjacent hot junction 502 by guide plate 8 after cooling down between the cold junction, utilizes low temperature air to cool down to hot junction 502, further heats heat exchange plate 5 to the heat exchange efficiency of working medium.
The working principle of the invention is as follows:
when the number of the heat exchange plates 5 is required to be installed or increased, the T-shaped rails at the upper ends of the heat exchange plates 5 slide into the short sliding grooves, the connecting plates 6 are pushed out of the guide rails 4 by the heat exchange plates 5 along with the continuous pushing of the heat exchange plates 5, finally the two clamping shafts 602 are separated from the short sliding grooves, the connecting plates 6 are in a vertical state, after the heat exchange plates 5 are completely pushed into the guide rails 4, an operator inserts a hexagonal wrench into the prismatic grooves on the rotating shafts 604, the buckling plates 603 are changed into a horizontal state from the vertical state by rotating the rotating shafts 604, the buckling plates 603 are buckled in the sliding ways 501 of the heat exchange plates 5, the connecting plates 6 realize the locking of the heat exchange plates 5 through the buckling plates 603, and the heat exchange plates 5 cannot be pulled out of the heat exchanger.
When the buckle plate 603 is located in the slide 501 and gradually changes from a vertical state to a horizontal state, the tightening plate 605 is gradually compressed, and finally, the positioning strip 606 is located in the positioning groove, and the tightening plate 605 makes the heat exchange plate 5 cling to the joint plate 6 by using the elasticity of the tightening plate 605.
When the connecting plate 6 is in a vertical state, as an operator twists the rotating shaft 604 positioned above, the large gear 607 drives the small gear 608 to rotate, the worm 609 rotates the worm gear under the drive of the small gear 608, the shaft sleeve 610 rotates in situ, the shaft sleeve 610 is rotatably arranged in the connecting plate 6 through the support plate, the support plate is in sliding connection with the pin shaft 611 in the vertical direction, the support plate is used for limiting the rotation of the pin shaft 611, the pin shaft 611 is pushed out of the connecting plate 6 by the shaft sleeve 610, when the shaft sleeve 610 rotates, under the action of a thread groove and a thread tooth, the upper end of the pin shaft 611 gradually extends out of the connecting plate 6 and enters a pin hole, the pin shaft 611 lifts the piston plate upwards, hydraulic oil in the hydraulic tank 401 enters the hydraulic cylinder 403, the bearing plate moves downwards under the pushing of the hydraulic cylinder 403, the sleeve 404 drives the sleeve 404 to extend out of the abutting plate 7, and the sleeve 404 and the abutting pipe 405 abut against the abutting joint opening 503 on the heat exchange plate 5. The sleeve 404 is inserted into the terrace, and the sealing gasket is in contact with the surface of the terrace, after the sleeve 404 is propped against the terrace, the end face of the inner side of the lower end of the butt joint pipe 405 is separated from contact with the piston 406 along with the continuous descent of the butt joint pipe 405, so that the sealing of the piston 406 to the butt joint pipe 405 is released, the inner space of the butt joint pipe 405 is communicated with the heat exchange flow channel in the heat exchange plate 5, and the working medium enters the heat exchange plate 5 through the butt joint pipe 405 and flows into the storage plate 1 through other butt joint pipes 405 after heat exchange.
The high-temperature working medium and the low-temperature working medium enter the storage plate 1 through the working medium pipes, enter the heat exchange plate 5 through the corrugated pipe 402, the butt joint pipe 405 and the butt joint opening 503, pass through the two left butt joint openings 503, the butt joint pipe 405 and the corrugated pipe 402 in sequence after the heat exchange of the high-temperature working medium and the low-temperature working medium in the heat exchange plate 5 is completed, and then are exposed out of the storage plate 1 through other working medium pipes.
When the splice plate 6 needs to be replaced, the operator inserts the shaft into the through hole, shrinking the distance between the two long shafts 601, and allowing the operator to remove the splice plate 6 from the rail 4.
When only the heat exchange plates 5 are required to exchange heat naturally, the hot ends of the heat exchange plates 5 face the same direction, and the hot ends 502 of the heat exchange plates 5 are close to the cold ends of the adjacent heat exchange plates 5.
When the heat exchange of the heat exchange plates 5 is required to be quickened, the hot end 502 of the heat exchange plate 5 is close to the hot end 502 of the adjacent heat exchange plate 5, the wind row 9 is arranged in the T-shaped slide way 501 on the adjacent two heat exchange plates 5 through a frame, and the guide plates 8 are clamped with the clamping shafts 602 through clamping plates 801 at two ends; the two ends of the clamping plate 801 are positioned between the two adjacent hot ends 502, and the wind row 9 is positioned between the two adjacent cold ends.
Through setting up wind row 9, the accessible fan increases the circulation of air between two adjacent cold junction, and the air is sent into between two adjacent hot junction 502 by guide plate 8 after cooling down between the cold junction, utilizes low temperature air to cool down to hot junction 502, further heats heat exchange plate 5 to the heat exchange efficiency of working medium.
