Heat transfer apparatus and container
A container for holding liquid is described. The container defines an inner region inside which liquid is adapted to be held and includes one or more walls for facilitating heating or cooling of the liquid therethrough, the one or more walls being adapted for invagination by a temperature control probe such that the temperature control probe extends into the container without directly contacting contents of the inner region of the container.
1. A system for heating or cooling the contents of a container, the system comprising:
a container configured to hold a liquid, the container having one opening region;
a closure to close the opening region of the container, the closure comprising:
an engagement portion to sealingly engage the opening region of the container;
a removable crown portion defining a recess extending into an inner region of the container via the opening region, the recess having an inner surface and an outer surface opposed to the inner surface, such that in use the inner surface is in fluid communication with contents of the container and the outer surface receives a temperature control probe to facilitate heat transfer to or from contents of the container by the temperature control probe, the crown portion attached to or integral with the engagement portion;
an overcap configured to engage with the opening region of the container and to secure the crown portion to the container, the overcap including an access aperture so that the crown portion is accessible to the temperature control probe without removing the overcap; and
a dock configured to receive the container, the dock comprising:
the temperature control probe configured to engage with the recess of the crown portion on the container; and
a temperature controller operatively connected to the temperature control probe, such that the temperature controller controls the temperature of the temperature control probe to heat or cool contents of the container via the recess without the probe contacting the contents of the container.
2. The system of claim 1 wherein the crown portion comprises a resilient material.
3. The system of claim 2 wherein the resilient material comprises a membrane having a thickness of about 0.5 mm to 10 mm.
4. The system of claim 1 wherein the crown portion comprises a substantially rigid material so that the crown portion extends into the inner region of the container.
5. The system of claim 1 wherein the crown portion includes one or more projections increasing a surface area for facilitating heat transfer between contents of the container and the crown portion by the temperature control probe.
6. The system of claim 1 wherein the dock includes a dock base and the temperature control probe extends upwardly from the dock base.
7. The system of claim 6 wherein the dock includes two or more temperature control probes.
8. The system of claim 1 further comprising a temperature sensor to sense an initial temperature of a liquid in the container prior to control of the temperature of the liquid.
9. The system of claim 1 further comprising a user input terminal to receive user inputs including inputs selected from the group consisting of: a final desired temperature of the liquid, a specific heat of the liquid, a weight of the liquid in the container, and a maximum permissible liquid temperature.
10. The system of claim 9 having a processor adapted to calculate an output energy required to obtain a final desired temperature of the liquid based on user inputs to the user input terminal.
11. The system of claim 1 further comprising a sensor to sense the weight of the liquid in the container.
12. The system of claim 1 further comprising a power source.
13. A method of heating or cooling the contents of a container, the method comprising the steps of:
adding a liquid to a container having one opening region;
closing the container with a closure configured to close the opening region of the container, the closure comprising:
an engagement portion to sealingly engage the opening region of the container;
a removable crown portion defining a recess extending into an inner region of the container via the opening region, the recess having an inner surface and an outer surface opposed to the inner surface, whereby in use the inner surface is in fluid communication with liquid in the container and the outer surface receives a temperature control probe to facilitate heat transfer to or from liquid in the container by the temperature control probe the crown portion attached to or integral with the engagement portion; and
an overcap configured to engage with the opening region of the container and to secure the crown portion to the container, the overcap including an access aperture so that the crown portion is accessible to the temperature control probe without removing the overcap;
mounting the container containing the liquid in a dock to receive the container, the dock comprising:
the temperature control probe configured to engage with the recess of the crown portion on the container; and
a temperature controller operatively connected to the temperature control probe, the temperature controller controls the temperature of the temperature control probe to heat or cool liquid in the container via the recess without the probe contacting the liquid in the container; and
heating or cooling the liquid in the container using the temperature controlled probe positioned in the recess of the crown portion.
14. The method of claim 13 further comprising the steps of:
measuring an initial temperature of liquid in the container;
obtaining one or more of the following data:
i. the final desired temperature of the liquid in the container;
ii. a specific heat capacity of the liquid in the container;
iii. a weight of the liquid in the container;
iv. a heat loss correction factor; and
calculating an amount of energy required to heat or cool the liquid to the desired temperature as a function of the initial temperature and one or more of the data of i to iv.
