With reference to the specific embodiment that Fig. 3, Fig. 3 are embodiment of the present invention water module base plate, water module base plate 1 in the present embodiment, comprise plate body 11, plate body 11 for installing each parts of water module, simultaneously, plate body 11 is provided with through hole, and through hole can make the air circulation of plate body 11 both sides.
The water module base plate 1 that the embodiment of the present invention provides, comprise the plate body 11 for installing each parts in water module, when unit refrigerating operaton, temperature difference inside and outside unit causes the hot pressing of water inside modules, " gravity-flow ventilation under hot pressing function " principle in applicable industry draught principle, plate body 11 offers through hole, the air circulation of plate body 11 both sides can be made, outside hot-air and the cold air convection heat exchange of water inside modules, define good ventilation heat exchange effect in water inside modules, the temperature of water module base plate 1 can be improved accordingly; On the other hand, the edge panel beating of through hole directly touches hot outside, water module base plate 1 last point of cold is counteracted further by heat conduction, the temperature of water module base plate 1 also can be improved accordingly, higher than the dew-point temperature of air, thus prevent water module base plate 1 to produce condensation water, and then decrease unit and the damage of installing metope.In addition, the inside of water module also has water pump sound and cool matchmaker's flow noise, and plate body 11 offers through hole, avoids whole water module forms resonator and noise source strengthening when noise produces.In addition, plate body 11 offers through hole, effectively can alleviate the weight of whole unit, thus reduce the mass loading to load bearing wall.
The cooling of water module base plate 1 is on the one hand due to cold emission, is because the bolt between panel beating and panel beating is fixed and the heat conduction of contact in face on the other hand.In order to anti-sealing module base plate 1 condensation, inventor, by test, analyzes and demonstrates in above two reasons which is the main cause causing water module base plate 1 to lower the temperature.
With reference to Fig. 4, when water module base plate 1 does not offer through hole, thermocouple is arranged at each position point of water module, have recorded the temperature of each measuring point in detail, simultaneously, the temperature data of each measuring point is analyzed, measuring point 07 " bottom electrical heating " in first: Fig. 4 is the temperature minimum point in water inside modules, its temperature is 12.8 DEG C, if cold emission accounts for leading factor, so the temperature of measuring point 09 " the large base plate upper left corner " should be close with it, but the temperature of the measuring point 09 of actual measurement is 23.9 DEG C, and the impact of visible cold emission on water module base plate 1 temperature is less.Second: the bulk temperature of electrical heating 4 should be lower than the bulk temperature of water pump 6 (due to same water temperature, water pump 6 has self running heating), then measuring point 05 " nearly electrical heating nut point " is lower than the temperature of measuring point 02 " nearly charging pump nut " or temperature is consistent.But the measuring point 05 of actual measurement is 24.9 DEG C, and measuring point 02 is 22.5 DEG C, and the temperature of measuring point 05, on the contrary higher than the temperature of measuring point 02, thus, also can show that the impact of cold emission on water module base plate 1 temperature is less.3rd: the temperature of measuring point 06 " fluid reservoir fixing point " is 15.1 DEG C, it is the secondary low spot of whole water inside modules temperature, and be 24.1 DEG C near measuring point 08 " the large base plate right jamming button " temperature that fluid reservoir 8 is nearest, the temperature difference of nearly 10 DEG C is had with 15.1 DEG C, in conjunction with above three criterions, can learn that cold emission is not the main cause causing water module base plate 1 to be lowered the temperature.4th: because the topmost low-temperature receiver region of water module base plate 1 is the position of lower middle at water pump 6, plate type heat exchanger 7, fluid reservoir 8 place, therefore, isothermal holding has been done to three large cool source member.The observed temperature of the measuring point 01,02,03,04,05 in Fig. 4 is: 20.8 DEG C, 22.5 DEG C, 23.4 DEG C, 24.6 DEG C, 24.9 DEG C, namely from the peak of water module base plate 1 down, form the temperature difference of successively decreasing step by step, simultaneously, the position relationship of these points, be on condensing drip to drip tray 3 after, by drip tray 3 cold is transmitted to the temperature difference step by step formed after on water module base plate 1.The mode of the heat transfer of low-temperature receiver region and water module base plate 1 has heat conduction and heat loss through convection two kinds, owing to all having done isothermal holding to three large cool source member, therefore, the impact of heat loss through convection is very little, thus, forming main cause that water module base plate 1 temperature reduces is that bolt between panel beating and panel beating is fixed and the heat conduction of contact in face.
In addition, bolt between panel beating and panel beating to be fixed and the heat conduction of contact in face is that the main cause causing water module base plate 1 temperature to reduce has carried out demonstration test, first: fluid reservoir 8 is fixed panel beating from after water module base plate 1 is separated, when fluid reservoir 8 is in hanging shape, water module base plate 1 almost no longer condensation herein.Second: drip tray 3 panel beating is pulled down from water module base plate 1, and after being removed by condensed water, the temperature of measuring point 01 " primary and secondary buttcover plate " rises to 26.8 DEG C from 20.8 DEG C, visible, and the water be condensed on drip tray 3 can form the heat conduction temperature difference of 6 DEG C.In conjunction with above 2 points, the bolt demonstrated between panel beating and panel beating is fixed and the heat conduction of contact in face is the main cause causing water module base plate 1 temperature to reduce, simultaneously, due to the mode released cold quantity that cold emission is with a kind of disperse, rate of release is slower, and the bolt between panel beating and panel beating is fixed and the heat conduction of the contact in face is mode released cold quantity with convection current, rate of release is very fast, therefore, the bolt demonstrated theoretically between panel beating and panel beating is fixed and the heat conduction of contact in face is the main cause causing water module base plate 1 temperature to reduce, binding tests and theory, preferably offer multiple through hole, and the position of multiple through hole is corresponding with the installation region of each parts of water module respectively, thus, outside hot-air flows into water inside modules from multiple through hole, simultaneously, from the edge of through hole, by heat, the bolt led between panel beating and panel beating is fixed and the contact in face, be equivalent to counteract a part of cold, thus, the bolt that improve between panel beating and panel beating is fixed and the temperature of contact in face, thus prevent water module base plate 1 to produce condensation water, and then decrease unit and the damage of installing metope.
