The specific embodiment
Through accompanying drawing and combine embodiment, the present invention is further specified below, following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of multithread road parallel-flow evaporator; As shown in Figure 1, comprise header 2, radiating tube 8, heat-radiation belt 7, side plate 10, inlet tube 5 and outlet 6, a plurality of radiating tube vertical spacings laterally arrange; Between the adjacent radiating tube heat-radiation belt is installed; Difference cross connection one header at the two ends up and down of this radiating tube, header side, said upper end is equipped with an inlet tube and an outlet, at the two ends of two headers side plate is installed vertically.
Its innovative point is:
A side of corresponding inlet tube and outlet vertically is provided with a plurality of and above-mentioned radiating tube shape, big or small identical secondary radiating tube 12 between the said biside plate; Secondary heat-radiation belt 11 is installed between the adjacent pair radiating tube; This pair heat-radiation belt and heat-radiation belt are for being made into integration secondary header 1 about the two ends up and down of secondary radiating tube difference cross connection one is parallel connected with last lower header;
At the header inwall of upper end one upper spacer 4 is installed, this header inside is divided into two independent cavity,, the header inside of lower end is divided into two independent cavity at the same lower clapboard 9 of installing of the lower header inwall of corresponding upper spacer;
At last secondary header left part inwall three dividing plates 3 with holes are installed at interval; This dividing plate with holes is divided into three Connectivity Sections with secondary header; Purpose is the flow velocity of buffering cooling fluid (not shown), and it can be evenly distributed in the secondary radiating tube, thereby increases effective circulation of cooling fluid; Inwall is installed secondary dividing plate 13 at the secondary header middle part of lower end, and the secondary header inside of lower end is divided into two independent cavity;
The installation quantity of said dividing plate is set according to the actual requirements.
As shown in Figure 6, between lower end header connected horizontally and secondary header, be shaped on a plurality of through holes 14 that are used to be communicated with two headers.
The diameter of said outlet is 18 millimeters, and purpose reduces flow resistance in order to improve the flowability of cooling fluid.
Between the said adjacent pair radiating tube secondary heat-radiation belt is installed, this pair heat-radiation belt and heat-radiation belt are for being made into integration.
Need to prove, for the shape and the position of clear expression radiating tube, hidden the part heat-radiation belt among Fig. 1.
In the present embodiment,, the cooling fluid flow direction is divided into four runners through the design of dividing plate and through hole is set, specific as follows:
1, first passage, cooling fluid flows in the header of lower end from inlet tube
Cooling fluid gets in the header of upper end from inlet tube, and the dividing plate that is positioned at this header is blocked it with cooling fluid and flowed into to the left, and cooling fluid slowly flows in the header of lower end through radiating tube.
2, second channel, cooling fluid flows in the secondary header of upper end from the header of lower end end
The interior lower clapboard blocking-up cooling fluid of header that is installed in the lower end flows to the left; The through hole that cooling fluid is shaped on along the header inwall flows in the secondary header of lower end; Following secondary dividing plate blocking-up cooling fluid in this pair header flows into left, flows to the secondary header right part of upper end through secondary radiating tube.
3, third channel, cooling fluid is flowed in the secondary header of lower end by the secondary header left part of upper end
Cooling fluid flows on the left of the secondary header of upper end through three dividing plates with holes, flows in the secondary header of lower end through secondary radiating tube then.
4, the four-ways, cooling fluid flows to outlet from the secondary header of lower end
Cooling fluid flows in the header through some through holes that secondary header inwall is shaped on, and its lower clapboard stops cooling fluid to flow to the right, and cooling fluid receives external pressure to flow to outlet through radiating tube.
The present invention makes cooling fluid circulate in order according to runner through the through hole of some dividing plates and design is set in header, effectively cooling fluid is evenly distributed in each radiating tube; And effectively circulate according to the flow direction; Effectively improved heat dispersion, and outlet is 18 millimeters by 16 millimeters original increases, improves the coolant flow performance; Effectively reduce flow resistance, and improve the radiating effect of evaporimeter.
