Description

Incubator humidification and condensation equipment

Technical field

The utility model relates to a kind of incubator humidification and condensation equipment, belongs to experimental instrument and equipment field.

Background technology

In order to keep good culture environment, be conducive to the growth of bacterium, cell and tissue, incubator working space ambient moisture needs high as far as possible, general relative humidity remains on more than 95%, working space remains on high humidity always, when cavity inner wall temperatures at localized regions is lower than dew-point temperature, cause condensation.Water of condensation condenses in cavity corner or edge zone conventionally, for the microorganisms such as fungi, bacterium have been created growing environment, thereby pollutes whole cell culture environment, causes the failure of an experiment, and clean incubator number of times increases, and causes culture efficiency to reduce.Existing incubator adopts following 2 kinds of forms to solve above problem conventionally:

First kind of way, tilting sink structure is made in inner bag bottom, and outside inner bag back, lower end regional area adds cold plate, artificially creates a condensation point.In machine normal course of operation, in tank, put into a certain amount of water, by heating inner liner bottom tank, make humidity return to very soon high humidity.During the humidity that reaches capacity in cavity, saturated with moisture is condensed compared with cold spot and is back in the tank of inner bag bottom in inner bag back inside lower end, the shortcoming of this kind of structure is that inner bag bottom needs to be processed into tilting tank form, and processing difficulties and cost are high, and water of condensation is clean inconvenient.

The second way, water pond adopts and forms (inner disc and outer disk) by two Stainless Steel Discs, incubator built-in fans is led cool ambient air inner disc lower end so that is formed a cool region through specific ducting system, water evaporates in outer disk, moisture is met colder inner disc and is condensed, on cavity wall and glass door, just there will not be like this condensation vapor, so circulation, guarantees that inner chamber reaches lasting saturated humidity environment.The shortcoming of this kind of structure is that water pond is made into double disk structure, and cost of manufacture is high; Built-in fans has noise, and blower fan movable part is short work-ing life, and the more complicated manufacturing cost of air channel structure is high.Dust is very easily assembled in the bottom constantly cooling fan of operation, and forms Aerosol Pollution source at incubator periphery, is unfavorable for that the incubator that clean environment is had relatively high expectations uses.

Utility model content

The purpose of this utility model be to provide a kind of incubator to close behind the door that humidity recovers fast, water of condensation is easy to clean and inner bag without being processed into tank form, handling ease, cost are low, the incubator humidification and condensation equipment of quiescent operation.

For solving the problems of the technologies described above, the utility model incubator humidification and condensation equipment, comprising: water pond, and described water pond is arranged on inner bag bottom; Thermal component, described thermal component is arranged between described inner bag and external environment, and fitting in described thermal component and described inner bag bottom, is arranged on the another side of described water pond and described inner bag contact position; First heater, described first heater is arranged on described inner bag; And secondary heating mechanism, described secondary heating mechanism is arranged on described thermal component.

At described thermal component, be provided with thermal component thermal insulation layer around.Described thermal component thermal insulation layer is connected with incubator thermal insulation layer.Described first heater is arranged on the another side of described water pond and described inner bag contact position.

The material of described water pond is stainless steel or copper or aluminium alloy.Described thermal component is stainless steel plate or copper coin or aluminium alloy plate.Described first heater and described secondary heating mechanism are heating cables.

The utility model incubator humidification and condensation equipment is after incubator start, start incubator heating unit simultaneously, first heater and secondary heating mechanism, reach after the humidity of user's setting, secondary heating mechanism quits work, and inner bag transmits heat on thermal component, and thermal component imports environment by heat again, make temperature in water pond lower than cultivating the temperature inside the box, can control aqueous vapor in incubator and be condensate in water pond.This device is by the wall of inner container of heating water pond position or adds thermal component and accelerate the speed that humidity in incubator rises and promote high humidity value to approach saturated humidity, and by controlling the heating unit working of damping device, thereby the lift velocity of controlling moisture, and make the interior condensate return of incubator to water pond.

The utility model incubator humidification and condensation equipment is placed water pond at incubator working space inner bag bottom centre position, and water pond surrounding temperature is identical with working space interior environment temperature.In water pond, pour water into, heat dissipation metal parts are placed in inner bag bottom, water pond center, and in water pond, water temp is lower than working space envrionment temperature, have formed a condenser zone like this at incubator working space.When inner bag bottom incubator heating unit and first heater energising heating water pond, the water temp in water pond raises and constant evaporation, and water extraction in water pond has supplied a controlled condenser zone.By the heating of partial condensation area decreases, also heat radiation, maintain in water pond water in lesser temps, even, in the situation that workspace temperature fluctuates, other region of working space comprises that each sidewall surfaces temperature of inner bag is higher than the surface temperature of water in water pond.Like this, water of condensation trend condenses in the middle of water pond, and other position, incubator internal work space does not form water of condensation.

In water pond and water pond, the surface temperature of water can be controlled by heating and cooling interior plate.In inner bag bottom, minute two-way arranges that heating cables ，Yi road is that incubator heating unit ,Yi road is first heater, and incubator heating unit is evenly distributed on inner bag bottom and water pond edge regional location.It is a reserved region, water pond central position that first heater is distributed in water pond surrounding interior region ，Dan inner bag bottom centre region, does not arrange heating cables, and be connected with thermal component on it, and periphery adopts thermal insulation layer sealing.Like this, the heat of the water in the middle of water pond is derived heat in time by the thermal component of inner bag bottom, maintained the low spot of water surface temperature in water pond, and thermal component periphery adopts thermal insulation layer sealing, guarantee that freezing air can not affect the air chamber temperature between inner bag and thermal insulation layer, be beneficial to the homo(io)thermism of working space.

After machine start, start humidity in incubator heating unit and first heater so that casing simultaneously and rise to very soon more than 95%, normal operating conditions, closes first heater, and in casing, water of condensation condenses in water pond.Thermal component is placed on the condensation that inner bag bottom centre position is more conducive to water of condensation, and has a segment distance apart from inner bag left and right sidewall and glass door, the possibility that when having reduced like this water in cooling water pond, cooling other position causes water of condensation to condense thereon.
